Abstract

A pilot hole is drilled in a ground by a first drilling unit having a rotary table and a down-the-hole drill. A guide rod is inserted into the pilot hole . A second drilling unit is then mounted on the guide rod. This second drilling unit is provided with an earth drilling bucket for drilling the ground, hydraulic cylinders for fixing a stationary unit of the second drilling unit on a wall of a target borehole in the ground , and another hydraulic cylinder for causing the earth drilling bucket to advance. Drilling reaction force during boring work can thus be supported by both the wall of the target borehole and the guide rod. While being rotated, the earth drilling bucket is caused to advance over a distance corresponding to a stroke of the hydraulic cylinder. This operation is repeated until the target borehole is formed over its entire length.

Figure 27 illustrates the lateral view that another different tradition is bored pick method and drilling machine, and Figure 28 shows the magnification ratio lateral view of the unit of rig described in Figure 27.

By conventional art shown in Figure 27, be used for boring the pick up drilling machine 220 of base 218 target borehole 219 fixed mechanism 240 is housed, fixed mechanism 240 fixedly creeps into the main body of auger 220 by pressing boring 219 wall, and drilling machine has a drilling tool 241 that is arranged under the main body.

Said fixing mechanism 240 respectively has the hydraulic cylinder 221 that an extensible plate 222 and that can be pressed on the drill hole wall 219 on the ground 218 is used to extend extensible plate 222 as shown in figure 28, thereby extensible plate 222 is pressed on the ground 218, and this hydraulic cylinder 221 also can make extensible plate 222 shrink and cause extensible plate 222 and ground 218 separately.Fixed mechanism 240 comprises the combination of some hydraulic cylinders 221 and extensible plate 222 and is arranged in the horizontal plane by three directions respectively.It should be noted that the fixed mechanism shown in Figure 27 and 28 has only two groups.In addition, these fixed mechanisms 240 are mounted on the fixed cell 233.

What be connected with fixed cell 233 bottoms is one by the rotating mobile unit 234 of bearing.Just constituted the main body of drilling machine 220 by these fixed cells 233 and mobile unit 234.

Mobile unit 234 is by rotating mechanism, and promptly motor 236 also is rotating.In addition, by propulsive mechanism, promptly hydraulic cylinder 235, are connected with fixed cell 233 at the one end, are connected with mobile unit 234 at its other end, and mobile unit 234 can move down with respect to the fixed cell 233 that is maintained fixed state.In addition, mobile unit 235 has a central cutter 237 in extreme lower position, have a neighboring cutter 238 that forms fixed drill bit in the position that is higher than central cutter 237, also have an outermost periphery cutter 239 that forms removable drill bit, this cutter can and shrink in the radial direction expansion.These central cutter 237, neighboring cutter 238 and outermost periphery cutter 239 are formed the drilling tool 241 that can bore digging, sand and rock.

The broken soil and the stone that bore pick by drilling tool 241 are to be inhaled in the loading bin 226 through a casting pipe when vacuum inhalator 224 is actuated.Subsequently, hack and stone pass through the bottom of loading bin 226 and discharge.Have a talk in passing, the end portion of casting pipe 225 is to inject to creep among the cylinder open 233a of auger 220 fixed cells 233, in the face of the position of the end portion of the casting pipe 225 of central cutter 237 rear walls has enough big pipe diameter.Position on boring 219 is provided with a upright derrick 223, and this derrick 233 is provided with a laser vertical degree tester 221, and the verticality tester is used to detect arbitrary off-centring between auger 220 central axiss and the central axis as target borehole 219.Derrick also has a suspension hook 231 that is used for promoting or falling according to hanging position drilling machine 220.

On the other hand, a TV camera 240a is installed on fixed cell 233 upper walls of auger 220, it can monitor said fixing mechanism 240, boring mechanism 235 and drilling tool 241.On ground, a monitoring panel 228, a power unit 229 and a generator 230 are arranged near the derrick 223.But from the vision signal of TV camera 240a with from the detection signal input monitoring dish 228 of laser vertical degree tester 227.Power unit 229 can be used as the hydraulic cylinder 22 that constitutes fixed mechanism 240, constitute the hydraulic cylinder 235 of boring mechanism and also make the hydraulic cylinder power source that outermost periphery cutter 239 is expansible and shrink.Generator 230 is as the power source of motor 236 grades.

Above-mentioned drilling machine 220, derrick 223 comprise laser vertical degree mensuration meter 227, comprise vacuum inhalator 224, the casting mechanism of loading bin 226 and casting pipe 225, monitor and control handwheel 228, power unit 229, generator 230 grades constitute the auger that creeps into that bores basic 218 the target borehole 219 of picking up together.

According to the conventional art shown in Figure 27 and 28, that bores that pick is to use as will being illustrated below structure creeps into that auger finishes.

For instance, just in time below derrick 223 pre-subdrilling dig a large diameter hole.Drilling machine 220 is reduced in the hole by hanging position by means of derrick 223, suspension hook 231.On this position, the hydraulic cylinder 221 of fixed mechanism 240 (described hydraulic cylinder as shown in figure 28) stretches and makes extensible plate 222 live in to state the wall in hole at a horizontal plane inner close fitting.Therefore, the fixed cell 233 of drilling machine 220 is fixed.

Then, rotate in motor 236 driven mobile units 234 that make simultaneously, the hydraulic cylinder 235 that constitutes propulsive mechanism stretches.Therefore, central cutter 237, neighboring cutter 238 and outermost side face periphery cutter 239 drop in the ground 218 when rotating, and therefore bore in ground 218 and excavate boring 219.When a stroke when removable unit 234 by the hydraulic cylinder 235 of propulsive mechanism reduces, motor 236 stalls.

When the hydraulic cylinder 221 that makes fixed mechanism 240 shrank in this position, extensible plate 222 left hole 219 walls in the ground 218.Therefore, the hydraulic cylinder 235 of propulsive mechanism is shunk.For instance, by the weight of fixed cell 233 itself, fixed cell 233 is descended towards mobile unit 234.

Then, the hydraulic cylinder 221 of fixed mechanism 240 is stretched again, thereby extensible plate 222 is close to by the wall of digging the boring 219 that forms by brill.Thereby the fixed cell 233 of drilling machine 220 is fixed.

Then, 236 driven whiles of motor, moving meter 234 is rotated, and the hydraulic cylinder 235 of propulsion plant is stretched.Therefore, be similar to aforesaidly, the total length of boring the hole 219 of pick is equivalent to the stroke of hydraulic cylinder 235.By repeating similarly to bore pick operation, the hole that can bore the pick Len req.

In above-mentioned brill pick process, sucks in the loading bin 226 via casting pipe 225 by actuating vacuum inhalator 224 owing to boring hack and the sillar that pick is collected at central cutter 237 rear walls, subsequently, outside the bottom by loading bin 226 is discharged to.

In above-mentioned brill pick process, off-centring, i.e. the misalignment that between the central axis of the central axis of drilling machine 220 and target borehole 219, occurs or according to hardness or pliability and its unevenness of ground 218 soil, and make drilling machine occur tilting.Under this situation, be the detection signal of response from 227 outputs of laser vertical degree tester, correct the signal of off-centring or gradient from monitoring panel 228 outputs one.For replying last signal, select one with one of relevant hydraulic cylinder 221 of formation fastening devices 240 so that its stretching, extension or contraction.

In addition, the operation of fixed mechanism 240 and drilling tool 241 etc. can be monitored on monitoring panel 228 by the vision signal from TV camera 240a output.

Yet the existing indivedual residual problems of above-mentioned conventional art will be illustrated hereinafter.

By the way, first conventional art of Figure 24 A and 24B need be arranged the additional process of drilling machine main body 175 and also for following tunnel reaming bit 172 is installed in additional process on the drilling rod 171 for forming the tunnel.So just increase more brill pick operation and bored the pick expense.In addition, the hole of waiting to bore pick must be less than substrate 174, and the diameter of therefore waiting to bore the hole of pick is restricted.

In addition, for producing driving power, second conventional example shown in Figure 25 need be adjusted the big gravimetric value of drilling pipe 181 weight in advance.Although not shown in the drawings crane also needs a goliath.Therefore generally speaking, drilling machine is that volume is big and benzene is heavy, and machine is transported to the problem that the operation of boring on the pick building site relates to the transportation difficulty.Moreover second conventional example is to avoid ground 180 slumps to need the water feed apparatus of a large amount of feeding waters 186, and is to discharge a large amount of mud need dispose the mud discharger that contains mud discharge pipe 185, and not shown suction pump etc.Therefore, this just can not bore pick, unless can arrange such water feed apparatus and mud discharger.Can cause the more pick operation of boring to bore the pick expense like this with raising.On the other hand, constitute the suction pump of water feed apparatus and mud discharger basically owing to be subjected to the restriction of capacity, therefore the mud amount of discharging also is restricted.Consequently, the bore dia that can bore pick is subjected to the restriction of employed drilling pipe 181.

On the other hand, in the 3rd conventional art shown in Figure 26, it is big and weight is big that crane 196 and counterweight pedestal must be designed to shape, so that can bear reaction force in brill pick process.Therefore, it is difficult crane 197 or the like being transported to the brill pick required operation in building site.More brill pick operations can be caused like this, thereby the pick expense of boring can be increased.Moreover, relate to drilling pipe (sleeve pipe) 193 diameters and on it is made, restricted or be restricted, therefore, the aperture that needs to bore pick also is restricted.

As mentioned above, pick is bored in the lifting of first conventional art, promptly bores the brill pick boring method of pick vertical shaft and bores the pick auger, needs upper and lower tunnel, therefore, can not bore pick in common ground.Recycled back in second technology is bored the swinging drilling pipe driver of pick and the 3rd technology, two kinds of technology respectively in boring the pick process, bear reaction and guarantee to bore the pick instrument propulsive force each need a kind of big overall size and drilling machine of extremely weighing of weight.Be difficult with the drilling machine conveyance to the operation of boring the pick building site like this, cause the more operation of needs to bore pick and make the brill pick expense problem of higher that becomes.

Moreover, all above-mentioned conventional arts be generally used for diameter reach 2 to 3 meters or thereon under brill pick boring, cause treating another problem of the target borehole diameter restrictions of boring pick.When construction, for example the power transmission tower in the mountain area as their basic hole, must form the boring that the aperture reaches the 3-4 meter in ground.Be to bore the big like this aperture of pick, also must be designed to big overall size and heavier weight according to the various drilling machines of above-mentioned this technology, yet so a kind of rig basically is difficult to build.Even this drilling machine is feasible, when boring the pick hole in the mountain area, also must transport to brill pick building site by this large-scale and heavy machine, this is inconvenient for hauling operation.It is impracticable that difficult transport makes the actual use of arbitrary conventional art.Therefore, present case, the basic hole of boring each power transmission tower of pick in the mountain area is to rely on the artificial pick of boring.Therefore, require more operational sequence.

It seems that it is impracticable improving the efficient of boring pick work, thereby can cause boring the increase of pick cost.

In addition, according to the conventional art shown in Figure 27 and 28, boring pick and fixedly behind the drilling machine, only extensible plate 22 is being accomplished the fixing of drilling machine 220 near firmly holing 219 walls.Under the quality influence of ground 218 and/or since with the hydraulic cylinder 221 that constitutes fixed cell 240 among stroke difference, behind fixing drilling machine, sizable off-centring will certainly appear between the central axis of the central axis of target borehole 219 and drilling machine 220, and/or bigger inclination will certainly appear in drilling machine 220 in boring the pick process.Under such a case, need expensive time control operation to adjust and to proofread and correct the position of drilling machine 220.Therefore just be difficult to expect the improvement of arbitrary brill pick operating efficiency.

Moreover drilling machine 220 can produce a large amount of vibrations and survey the reflecting surface of meter 227 except form the laser vertical degree on a drilling machine part, just is left with no alternative.Therefore be difficult to detect above-mentioned off-centring and/or gradient.So just be difficult to bore pick one hole with high-accuracy verticality.

The present invention improves in view of the present circumstances of above-mentioned conventional art is existing.

Below, the boring method that creeps into of the present invention will be illustrated based on accompanying drawing with the embodiment that creeps into auger.

Figure 1A to 1F is the schematic diagram that creeps into boring method according to the claim 1,2,3,4,5,6 that is equivalent to the application, 8 and 9 first embodiment.

Shown in Figure 1A, in this embodiment, creep into a diameter and be positioned on the ground 1 less than the first rig unit of the pilot hole (location drilling just) of target borehole.First creeps into unit comprises that (down-the-hole) drilling tool 2, in the well that creeps into locating hole is as the hydraulic power unit 4 of the drive source of drilling tool in the well 2 and rotating disk 3 and (unshowned) compressor as the driving force of drilling tool in the well 2.By the way, as disclosing at Japan special permission publication application number HEI 3-119284 and SHO 63-312497 like that, the rig unit that the interior drilling tool 2 of well is housed is well-known.

When starting hydraulic power unit under the state at Figure 1A rotating disk 3 being rotated, creeping into of drilling tool 2 is that air by the compressor shown in Figure 1B provides is finished in the well.Broken soil that produces by creeping into and stone can face toward drilling area blowing and they are discharged to the outside of ground 1 by the air of for example being supplied with by compressor.Under above-mentioned state, upwards in the winding shaft during drilling tool 2, in ground 1, formed a locating hole 6.

In this embodiment, a derrick 62 uprightly be installed in Fig. 1 C clearly shown in locating hole 6 above.Derrick 62 is provided with a capstan winch 63.In this case, can insert guide rod 7 in the locating hole 6, and the second rig unit (drilling well unit head) 8 of a formation diameter greater than the target borehole of locating hole 6 is assemblied on the guide rod 7.This can cause guide rod 7 to be passed in the extended situation of the formed cylindrical aperture in the second rig unit, 8 centers.Although in this embodiment, guide rod 7 is inserted into by in the 2 formed locating holes 6 of drilling tool in the well,, drilling tool 2 also can be used as guide rod 7 in the well.Here, some pulleys 66 top and derrick 62 of being installed in the second rig unit 8 also is provided with a pulley 64.The wire rope 65 of the outside volume pine of the capstan winch 63 on one derrick 62 is wrapped on the pulley 64 of all pulleys 66 of the second rig unit 8 and derrick 62.One end anchor of wire rope 65 fixes on the derrick 62.Therefore, wire rope 65 can be rolled up pine or rolling-in by driving capstan winch 63, so that the second rig unit 8 can be descended at the bearing of trend of suspension status lower edge guide rod 7 or mention.

The second rig unit 8 comprises the drilling tool that creeps into ground 1, makes mechanism that drilling tool rotates on horizontal plane, advances the mechanism of drilling tool and with respect to the fixing mechanism of the main body of rig unit of ground 1.Say that by the way the driving power source of above-mentioned rotating mechanism, propulsive mechanism and fixed mechanism is above-described hydraulic power unit 4.Thereby, the primer fluid pressure device can optionally drive rotating mechanism, propulsive mechanism and the fixed mechanism of the second rig unit 8, when driving that fixed mechanism fixes the top that constitutes rig unit 8 and when then being maintained fixed the position and driving rotating mechanism and propulsive mechanism with top, the drilling tool that is installed in the bottom that constitutes main body is advanced downwards along guide rod when being rotated, thereby make drilling tool can in ground 1, bore pick one vertical drilling (vertical shaft) as required target borehole.

In this case, for example the main body of the second rig unit 8 should so be constituted, so that the said fixing mechanism that main body can support on it is installed also also has the movable part 19a that the fixed part (unit) 10 and that can fix on the formed target borehole 7a wall is clamped drilling tool in ground.The above fixed mechanism is to be used to extend and the hydraulic cylinder 60 that shrinks corresponding extensible plate 61 is constituted by some extendible plates 61 and some, and wherein, these plates can be close on the wall of target borehole 7a.Above-mentioned rotating mechanism is made up of for example hydraulic motor 20, and movable part (unit) 12 is rotated on horizontal plane.Above-mentioned propulsive mechanism is made up of hydraulic cylinder 21, and it can make movable part 12 advance downwards.

When beginning to creep into operation with the second rig unit 8, at first drive the fixed mechanism of the second rig unit 8, that is to say, hydraulic cylinder 60 is extended, so that the fixed part 10 of the second rig unit 8 is fixed on the structural member of derrick 62.In this case, starting hydraulic power unit 4 is to drive as the hydraulic motor 20 of the rotating mechanism of the second rig unit 8 with as the hydraulic cylinder 21 of propulsive mechanism.Then, comprise that the movable part 12 that creeps into bucket 19a as the earthwork of drilling tool advances downwards when rotating, whereby, in corresponding to predetermined distance range, finished and crept into (boring pick) operation as the stroke of the hydraulic cylinder 21 of propulsive mechanism.After this, the second rig unit 8 is decommissioned.In this case, make hydraulic cylinder 60 withdrawals to remove fixed part 10 with respect to the fixing of derrick 62 and driving capstan winch 63.So, fixed part 10 is descended in the scope of the preset distance that is equivalent to hydraulic cylinder 21 strokes by deadweight.

When hydraulic cylinder 60 is extended once more, extensible plate 61 is contacted with the wall that forms this boring 7a, so that fixed part 10 is fixed.Fig. 1 D represents to creep into after the end first time on spreading all over preset distance with the fixed part that is fixed on the derrick 62, carries out same several times operation and finish the situation of creeping on preset distance.In above-mentioned predetermined distance range each through same operation for several times finish creep into after, the position of fixed part 10 sd sos is even it is fixed on the wall of boring 7a of ground 1.Below will begin to do an explanation from state shown in Fig. 1 D.

Now, drive hydraulic motor 20 and hydraulic cylinder 21 once more.Shown in Fig. 1 E, comprise cubic metre of earth a movable part that creeps into bucket 19a 12 and in rotation, advance downwards as drilling tool, creep into so that in the predetermined distance range of the stroke that is equivalent to hydraulic cylinder 21, finish.

At this moment, rig unit 8 once had been stopped operation, and made hydraulic cylinder 60 starts, and made extensible plate 61 leave the wall of boring 7a.This releasing fixed part 10 fixedly be relevant with the wall of boring 7a in the ground 1.By driving capstan winch 63, cause fixed part 10 in the preset range that is equivalent to hydraulic cylinder stroke shown in Fig. 1 F, to descend by its deadweight.

Then, repeat similar operation with alternately mobile fixed part 10 and movable part 12.Therefore this makes might, in ground, can form required target borehole 7a in its length range by creeping into several times continuously in the predetermined distance range that is equivalent to hydraulic cylinder 21 strokes.

Such creeping in the operation process, for example broken soil and the stone that is produced by brill pick target borehole 7a then creeps on the rear wall of bucket 19a by utilizing a cubic metre of earth shape of creeping into bucket 19a to be stacked on the earthwork.Therefore, the broken soil that bores pick is like this pushed up with stone and can be taken out from boring 7a by driving capstan winch 63 and promoting rig unit 8.

After target borehole 7a forms, the second rig unit 8 is unloaded and takes out from target borehole 7a from guide rod 7.After the second rig unit 8 is taken out from above-mentioned target borehole 7a, similarly, guide rod 7 is taken out from target borehole 7a.Thereby, creep into operation and be accomplished.

According to the boring method that creeps into of this embodiment, the reaction force that produces during creeping into is born through the wall of the target borehole 7a that fixed mechanism is drilled in by ground 1.In addition, the reaction that produces during creeping into also can be born by the guide rod 7a with enough rigidity.Thereby, might limit this reaction force, so that in drilling process, can make the swing of the second rig unit 8 reduce to minimum.This just might creep into ground as the crow flies along the bearing of trend of guide rod 7, therefore can prevent the off-centring of central axis of the rig unit 8 relevant and the inclination that rig unit 8 is occurred, excavate boring 7a with high vertical precision thereby allow to bore with the central axis of target borehole 7a.In addition, be unwanted basically creeping into the dimensional orientation of adjusting rig unit 8 between operational period.This just can improve and creeps into efficiency of operation.Because boring 7a can be formed by high vertical precision, so just no longer need to do the diameter of boring 7a bigger.When among the boring 7a that concrete is irritated after into creeping into, the concrete of perfusion can be finished in minimum loss.

In addition, be designed to availablely cubic metre of earth creep into bucket 19a and discharge broken soil and stone.In other words, the earthwork is crept into bucket 19a also as a cubic metre of earth output mechanism.The earthwork is crept into bucket 19a and is generally known, the earthwork quantity that the as many brill of capacity that allows the accumulation and the earthwork to creep into bucket 19a excavates, and irrelevant with the situation of ground with the degree of depth of creeping into.Therefore might under the situation that does not need to dispose any special earthwork output mechanism, discharge broken soil and stone effectively.

As above illustrated, the reaction force that is produced in drilling process is born by target borehole 7a and guide rod 7.Therefore, itself to bear big like this reaction force by the second rig unit 8 be unnecessary in research.This makes might the little and lightweight second rig unit 8 of body plan shape.In addition, guide rod 7 can be designed to have less radial dimension, so that it can be inserted in the locating hole 6 of diameter less than target borehole 7a.Because these characteristics, just can be designed to the auger that creeps into that the first rig unit of interior drilling tool 2 of well and guide rod 7 and the second rig unit 8 are equipped with in littler and lighter the comprising of weight of its global shape.Therefore, can make to transport and comprise and be equipped with that drilling tool 2 and the first rig unit of guide rod 7 and the needed work of auger of creeping into of the second rig unit 8 become more or less freely in the well.Be associated therewith, can make and creep into required operation quantity minimizing, thereby might reduce drilling cost.

When wanting to form when having larger-diameter target borehole 7a, only need be to adjust the size of cubic metre of earth creeping into the size of bucket 19a or being similar to the second rig unit with the corresponding mode of the diameter of target borehole 7a.This makes the target borehole 7a that just might bore pick one required diameter, and need not increase guide rod 7 and the second rig unit basically in size and weight.Therefore, although suitable difficulty is still thought in the formation of this big target borehole so far, form that the target borehole 7a of the big diameter about 3 to 4 meters still can be easy to reach.

According to present embodiment, with creep into auger be transported to the operation of creeping into the building site be quite easily and the target borehole of 3-4 rice left and right sides diameter also carry out easily.Therefore, although pick is also bored in these basis borings up to now by hand, present embodiment also is applicable to the form of mountain area defeated ground tower or the boring of suchlike basis.For replacing the manual pick of boring, the formation in the basic hole of the suitable mountain area of this example power transmission tower etc. is crept into efficiency of operation thereby improved widely.

In the above embodiment, the broken soil that produces by creeping into and ten thousand also can be discharged by means of creeping into bucket 19a as the earthwork of drilling tool.Then, this broken soil and stone can use the combination of air or water supply and air that it is discharged to the outside of ground 1.

In the above-described embodiments, when after target borehole 7a forms, guide rod 7 being taken out from target borehole 7a, after the separation guide rod, just guide rod 7 can be taken out from target borehole 7a.

In the above-described embodiments, after target borehole 7a forms, the second rig unit 8 and guide rod 7 are moved to the outside of ground 1 from target borehole 7a.Unless such constructing inserted among the target borehole 7a and hindered such as tower, these second rig units 8 and guide rod 7 can be covered and they do not moved on to the outside of ground 1 with the tower of constructing, inserted among the target borehole 7a in for example ground 1.

In addition, in the above-described embodiment, a vertically extending boring is to creep into as target borehole 7a.But the brill that the invention is not restricted to this vertical drilling is dug.Might creep into the boring that direction that a boring of extending in the horizontal direction or one tilts at a predetermined angle with respect to vertical direction is extended.

In the above-described embodiment, when creeping into boring 7a, the earthwork is crept into when bucket 19a advances it is rotated on horizontal plane, so that creep into.But, might carry out the rotation of the drilling tool on the horizontal plane and the propelling of drilling tool each other independently.

For instance, the movable part 12 that comprises the main body of the second rig unit 8 can be used as one and has and replace the above-mentioned earthwork to creep into the drilling tool of bucket bucket 19a, that can rotate in vertical plane.Because the fixed part 10 of drilling tool 8 is fixed on the wall of formed boring 7a in the ground 1 through fixed mechanism, so, when the hydraulic cylinder 21 that extends as propulsive mechanism, bucket is rotated in vertical plane.Therefore, creep into and to carry out in the predetermined air line distance scope of the stroke that is equivalent to hydraulic cylinder 21 along the bearing of trend of guide rod 7.Then, bucket is retreated in above-mentioned predetermined air line distance scope at once.In this case, drive rotation motor (hydraulic motor) 20 as rotating mechanism, and make removable unit 12, promptly the bucket as drilling tool turns over a predetermined angle.Under this situation, as above illustrated, drive hydraulic cylinder 21 again reducing drilling tool, thereby, can make bucket can in predetermined air line distance scope, bore the base that picks up.In the same way, bore pick boring 7a to the degree of depth that is equivalent to preset distance.Then, remove the fixing of fixed cell 10 by fixed mechanism, so that fixed part can descend by for example its deadweight.On the other hand, in above-mentioned predetermined air line distance, creep into boring 7a again.Creep into by repeating, be included in the propelling of bucket in the predetermined air line distance scope and retreat with and the required target borehole 7a of rotation in above-mentioned predetermined angular range can on its whole length, form.It is this that what creep into defined in boring method and the claim 2 of the present invention is consistent.

Please consult above-described Figure 1A to 1F again, below will the practiced drilling operation of first embodiment that be crept into auger by above the present invention who constitutes be illustrated.

The first rig unit that comprises drilling tool 2, guide rod 7 in the well and the second rig unit 8 etc. are transported to the scene of creeping into.When creeping into operation, the first rig unit that at first will be equipped with interior drilling tool 2 of well and rotating disk 3 is installed on the ground 1 to creep into just like the pilot hole 6 of the diameter shown in Figure 1A less than target borehole 7a.In the state shown in Figure 1A, actuate hydraulic power unit 4 and rotating disk 3 is rotated and from compressor, air is input into drilling tool 2 in the well.Like this, creep into by drilling tool 2 in the well shown in Fig. 1 B accomplished.Face toward by the air of supplying with by compressor and drill the outside that the zone blowing is discharged to ground 1 by boring broken soil that pick produced and stone, then, drilling tool 2 in the winding shaft, thus in ground formation pilot hole 6.Guide rod 7 shown in Figure 5 is inserted in the pilot hole 6.

For instance, along with guide rod 7 is inserted in the pilot hole 6, the discharge platform that derrick of installing like that shown in Fig. 6 etc. 62 and operation are assemblied in the control room 80 moves switch 111.Therefore, the control module 100 that creeps into of a master signal slave controller 99 can be outputed to casting platform mobile unit 98.Casting platform 82 shown in Figure 12 and 13 moves outside derrick 62, is enough to make the second rig unit 8 to be placed on wherein big space thereby form.

By under the wire rope suspension situation, rig unit decline switch 86 or the rig unit of arrangements of operations in control room 80 promotes switch 87 at the rig unit in addition.As a result capstan winch driver element 95 by starting to drive the capstan winch 63 on the support 73 of derrick 62, therefore, as shown in Fig. 6 waits like that, the second rig unit 8 descends under suspension status or raises and be installed on the guide rod 7.Then, as shown by way of example among Fig. 9, required one or more hydraulic cylinders 79 it (four hydraulic cylinders, just forward and backward a, left side and right hydraulic cylinder) are optionally extended or shrink with moving load sensor 77 and pin 78, so that pin 78 is assemblied in the guide rod 7.Therefore, guide rod 7 is located in such a way, makes it can not swung.

When the second rig unit 8 begins to creep into operation, at first operate shown in Figure 15, be placed in and creep into firing switch 88 in the control room 80.Therefore, hydraulic fluid can be fed into four hydraulic cylinders 60 that constitute fixed mechanism, so that these hydraulic cylinders 60 are extended.As a result, can make extensible plate 61 press the corresponding reaction force base plate 76 of derrick 62, whereby, the fixed cell 10 of rig unit 8 is fixed on these reaction force base plates 76.In addition, also hydraulic fluid is supplied with hydraulic cylinder 19f,, and make removable drill bit 19e keep enlarging the position of creeping into diameter so that hydraulic cylinder 19f is extended.The state that STA representation shown in Fig. 6,7,8 and 9 is obtained at this moment.

In this case, under to the response of the master signal exported the control module 100 from creeping into of controller shown in Figure 15 99 starting as the hydraulic motor 20 of rotating mechanism with as the hydraulic cylinder 21 of propulsive mechanism.So removable unit advances downwards when rotating,, just bore native bucket 19a, fixed drill bit 19d and can move drill bit 19e and can in the predetermined distance range of the stroke that is equivalent to hydraulic cylinder 21, creep into operation so that by drilling tool.

At this moment, operation in the control room 80 creep into shutdown switch 89 after, some signals are exported in creeping into of slave controller 99 in the control module 100, so that stop solution pressure motor 20 and hydraulic cylinder 21 operations, the hydraulic cylinder 60 that forms fixed mechanism is shunk so that extensible plate 61 separates with the reaction force base plate 76 of corresponding derrick 62, make the hydraulic cylinder 19f withdrawal of removable drill bit 19e.

When under this situation, operate in the rig unit decline switch 86 in the control room after, at creep into master signal that control module 100 exported under the starting capstan winch driver element 95 of response by controller 99.By the deadweight of rig unit 8 fixed cells 10, can make hydraulic cylinder 21 withdrawals, thereby fixed cell 10 can be landed towards removable unit 12.After fixed cell 10 descended in predetermined distance range, capstan winch driver element 95 was out of service.

After repeating this operation for several times, operate again and creep into firing switch 88 in the control room 80.At this moment, the hydraulic cylinder 60 of fixed mechanism is moved so that each extensible plate 61 is pressed on the wall of the boring 7a that creeps into, thereby make fixed cell 10 by firmware.In addition, primer fluid pressure motor 20 and also as the hydraulic cylinder 21 of propulsive mechanism, this advances removable unit 12 downwards under rotating, therefore, can creep into bucket 19a, fixed drill bit 19d and removable drill bit 19e holes in the predetermined distance range that is equivalent to hydraulic cylinder 21 strokes by the earthwork.

Then, repeat similar operation until make the broken soil of sufficient amount and stone is deposited in and cubic metre of earth creeps among the bucket 19a.In the above drilling operation, Fig. 1 D and Figure 10 show that fixed cell 10 directly is fixed in the target borehole by fixed mechanism and situation is before crept in starting.On the other hand, Fig. 1 E represents to finish with respect to the situation of creeping in the preset distance of hydraulic cylinder stroke.In addition, Fig. 1 F shows in order to carry out creeping in the next preset distance, and fixed cell 10 has been fixed on situation among the target borehole 7a by fixed mechanism.

When repeat drilling operation in preset distance after, when a considerable amount of broken soil and stone be deposited in the earthwork and creep into the interim storage 19c of portion of bucket 19a, the rig unit in the operation control room 80 promoted switch 87.As a result, the master signal that control module 100 is exported that creeps at response slave controller 99 just starts capstan winch driving switch 95, makes rig unit 8 be raised (rising) to the derrick 62 that is arranged in target borehole 7a top under suspension status.At this moment, the casting platform that operates in the control room 80 moves switch 111.Thereby, make casting platform 82 move to rig unit 8 bottom-right positions.In this case, be operable in casting firing switch 90 in the control room 80.Creeping under the master signal of being exported in the control module 100 of response slave controller 99, hydraulic fluid is fed to the earthwork and creeps into the cylinder pressure 97 that bucket is opened/closed, and is opened so that the bucket bottom is crept in the earthwork.Thereby, broken soil and stone are crept into bucket 19a removal to the casting platform 82 that shows of Figure 12 from the earthwork.After the removal of finishing broken soil and stone, operate in the casting shutdown switch 91 in the control room 80.As a result, under to the response of creeping into the master signal that control module 100 exports of slave controller 99 and the opening/closing hydraulic cylinder 97 of bucket is crept in the starting earthwork, close the bottom that bucket 19a is crept in the earthwork whereby.When and then switch 111 is moved in the operations platoon earthen platform, the starting casting platform that creeps under the master signal of being exported in the control module 100 at response slave controller 99 moves switch 98, thus make casting platform 82 and on loaded get out the outside that soil 83 is transported to derrick 62 together.Getting out soil 83 and can from casting platform 82, be shed on casting platform 82 by unshowned mechanism.

As shown in figure 14, accuse when finishing already or in the process of creeping into when target borehole 7a has formed on its whole length and crept into, when having found in target borehole 7a, to exist the gravel 85 that disturbs mutually with operation or suchlike erratic block, they separate guide rod 7 in the mode near rig unit 8, then operate the support that is installed in the control room 80 and move switch 110.The result, as Figure 13 and 14 is represented, under the response of creeping into the master signal of being exported in the control module 100, start unshowned support mobile unit and support 73 and move to the side, so that make rig unit 8 shift to the next door from the position on the target borehole 7a to slave controller 99.Therefore, the rig unit 8 that is hung by wire rope 65 can take off and it is removed from wire rope 65.The gravel 85 that will occur as shown in figure 14 in the target borehole 7a is removed, and places original position to continue to creep into operation guide rod 7 and rig unit.

After the second rig unit 8 is removed during in the end of job, the separating part that guide rod 7 is arranged that stays, the described part that still will be placed among the target borehole 7a also will be taken out from target borehole 7a.

In the above described manner, target borehole 7a can be crept into as the crow flies along the extension 7a of guide rod.

In addition, deal with separately by the detection signal of being exported from load cell 77, angular transducer 93 and range sensor 94 for the control that forms a more accurate target borehole 7a, rig unit 8 and carry out.Below, this control will be illustrated based on Figure 16 to 20.

Guide rod 7 also is provided with an above-described load cell 77.But, this load cell 77 for example is made up of the load cell or the similar device of diaxon detection type, therefore, can detect the power of the right angle intersection of X-Y direction in Figure 16.Two axes of coordinates X ' on Figure 16-Y ' represents diaxon (line), these two axles are exactly that fixed cell 10 at rig unit 8 connects the respect to one another of propulsive mechanism to be fixed when being fixed on the wall of target borehole 7a, that is four two axial lines (axle) that hydraulic cylinders 21 also extend with the right angle relative to one another.If being provided with, guide rod 7 and rig unit 8 prevent the mechanism of rig unit 8 around guide rod 7 rotations, the X-Y axis is in advance by the direction of load cell 77 detected power, it can with the X '-Y ' axial alignment (location) that can be set in hypothetically on the rig unit 8.In this case, just do not need the above-mentioned angular transducer 93 that is arranged on the rig unit 8.Because above-described anti-locking mechanism is not set in first embodiment, so owing to hang the reversing of wire rope 65 of rig unit 8, anyly attempt to be used in the X '-Y ' axis that sets on the rig unit 8 and almost can not succeed with align (location) of the X-Y axis of load cell 77.Therefore, 93 of the angular transducers of rig unit 8 are used as the power on the direction that is transformed into two axis of imaginaries the X '-Y ' that setting on the rig unit 8 in the power on the direction of two axial lines X-Y, wherein, the power on the two axial lines X-Y direction is detected by load cell 77.

In addition, as shown in Figure 18, can formulate following formula:

F＝P+N (1)

P×L ₂＝N×L ₁ (2)

In formula:

N: synthesizing resulting power by load cell 77 detected two power of pressing on the both direction X-Y.

F: in the drilling process of bucket 19a is crept in the earthwork, put on the bias load on the rig unit 8.

P: put on the reaction force on the guide rod 7.

L ₂Creep into the lower-limit point of bucket 19a and creep into distance between the approximate center point of bucket 19a from the earthwork that its short transverse is observed in the earthwork, this is to produce reaction force P on the bucket lower-limit point, and supposition is being similar under cubic metre of earth situation of the central point generation bias load F that creeps into bucket 19a.

L ₁Creep into the distance of the approximate center point of bucket 19a from the earthwork of observing in its short transverse to load cell 77.

Here, distance L ₂Can be looked at as the constant that shape determined that can creep into bucket 19a by the earthwork.As mentioned above, power N can be used as the synthetic of power, just the detected value that obtains by two axial lines X-Y direction that is detected by load cell 77.In addition, distance L ₁Be to determine according to the signal of from the above range sensor 94, being exported.Therefore, the reaction force P that puts on guide rod 7 can be calculated according to formula (2).In addition, based on above-mentioned determined reaction force P with by the measured composite force N of above-described load cell 77, just can determine to put on the value of the bias load F on (acting on) rig unit 8 according to formula (1).Bias load F is opposite with composite force N with reaction P on direction.

When creeping into operation, each detection signal of load cell 77, angular transducer 93 and range sensor 94 all is input to the misalignment control module 101 of the controller 99 that is installed in the control room 80.At this moment, misalignment control module 101 carries out for example coming the judgement of the composite force N of free load cell 77 detected two axial lines X-Y directions.In addition, according to by the variation on the length of range sensor 94 detected wire rope 65, also carry out distance L shown in Figure 180 ₁Judgement.Then, calculate to determine to put on the reaction force P of guide peg 7, according to calculating according to formula (1) by above determined reaction force P and composite force N.And exist relation shown in Figure 19 between all above determined composite force N, reaction force P and the bias load F.As shown in figure 20, at this moment, calculate according to the detection signal of angular transducer 93 so that will be transformed into power F ' on X '-Y ' axis, and determined the component of the power F ' on X '-Y ' axis direction at the bias load F on the X-Y axis.Then, calculate, in this target range scope, should make one of hydraulic cylinder 60 elongation of relevant fixed mechanism shown in Figure 16 and withdrawal so that these component are reduced to zero for the target range of determining operation.Output and start relevant hydraulic cylinder 60 in the misalignment control module 101 of the corresponding master signal slave controller 99 of Cao Zuo target range therewith in response to this master signal.

In above-described mode, might during bore operation, control the dimensional orientation of rig unit 8, therefore, rig unit 8 affords equal power basically along its whole peripheral surface.This makes and might make the central axis of rig unit 8 keep basically overlapping with the central axis of guide rod 7 when boring pick all the time, just keeps overlapping with the central axis of target borehole 7a.

First embodiment that creeps into auger of the above formation combines also and can bear reaction force and also can bear reaction force by guide rod 7 through the wall of fixed mechanism by target borehole 7a with the boring method that creeps into shown in above-mentioned Figure 1A to 1F, thereby can limit and reduce the swing of rig unit 8 in drilling process.This makes and might hole along the bearing of trend of guide rod 7, and can make the central axis of rig unit 8 reduce to minimum, so that can bore the boring 7a of pick one high vertical precision with respect to the misalignment of the central axis of target borehole 7a and the inclination of generation rig unit 8.In drilling process, just do not need to adjust the dimensional orientation of rig unit 8 basically, thereby making to improve creeps into efficiency of operation.Say that again boring 7a can be formed on high vertical precision ground, so that no longer need to make boring 7a to do unnecessarily greatly.When the boring 7a that concrete is poured into after creeping into, concrete can the least disadvantage amount be poured into a mould.

In addition, the earthwork is crept into bucket 19a also as casting mechanism.No matter the situation of ground and the degree of depth of creeping into, the earthwork are crept into bucket 19a and are allowed to pile up therein with the suitable quantity of the capacity of bucket 19a is crept in the earthwork and get out soil and stone.Therefore, might carry out the discharge of this soil that gets out and stone, and need not any special casting mechanism.

In the above-described embodiments, when beginning to creep into the second rig unit 8, reaction force is born by the reaction force base plate 76 on each pillar 71 that is installed on the derrick 62.Therefore, do not need other large-scale component to bear and creep into reaction force, thus generation interests economically.

Say that again reaction force is born by the wall and the guide rod 7 of above-described target borehole 74 in drilling process.Therefore, to the second rig unit 8 just do not need itself (needn't) consider to bear big reaction force, the second rig unit 8 can be done small and lightly for this reason.In addition, guide rod 7 can be designed to have so less diameter, makes and so long insert it in the pilot hole (locating hole) 6 of diameter less than target borehole 7a.Because these characteristics can form the little and lightweight auger that creeps into of its overall shape, this auger comprises the first rig unit and the second rig unit 8 that knot tool 2, guide rod 7 in the well are housed.Therefore, comprise the first rig unit and in the well adorned drilling tool 2, guide rod 7 and the second rig unit 8 creep into auger be transported to creep into on-the-spot just than being easier to.Because can reduce to creep into needed process number, might accomplish to reduce drilling cost.

To have larger-diameter target borehole 7a in order forming, only to need to adjust the size of drilling tool, for example with the corresponding to second rig unit 8 of the diameter of target borehole 7a on the earthwork creep into bucket 19a.Although the shaping of this big boring once was considered to suitable difficulty in the past, under size that does not cause the guide rod 7 and the second rig unit 8 and the substantive situation about increasing of weight, the target borehole of 3 to 4 meters left and right sides diameters can be easy to be formed.

That understands as mentioned above is such, because the rig auger being transported to the work at the scene of creeping into can be formed soon than the major diameter target borehole that is easier to about 3 to 4 meters, the auger that creeps into according to present embodiment also can be applicable to the power transmission tower in mountain area or constructing of suchlike basis boring, but constructing so far of this basis boring also finished by manual creeping into.

, can improve significantly and creep into efficiency of operation when being applied to the constructing of basis boring of the power transmission tower in the aforesaid mountain area when the creeping into that auger replaces manual creeping into of present embodiment.

Second embodiment that creeps into auger according to the present invention is illustrated below in conjunction with accompanying drawing 21 and 22.

As casting mechanism, this second embodiment is provided with the mechanism that discharges broken soil and stone, and these pulverize soil and stone sucks by vacuum, in other words, uses air pressure and is stacked on the interim storage compartment 19c that bucket 19a is crept in the earthwork.

According to this second embodiment, a vacuum unit 102 is positioned on the ground and a loading bin 104 that stores broken soil and stone is placed on the derrick 62.In the pipeline between loading bin 104 and vacuum unit 102, a strainer 103 is installed.One end of one casting pipe 105 is connected its lower end and then is in the position of creeping into the interim storage 19c of portion of bucket 19a in the face of the earthwork with loading bin 104.All the other structures are similar to the corresponding construction of above-described first embodiment.

In this second embodiment,, start vacuum unit 102 when wanting to discharge owing to the result who creeps into operation when being deposited in the earthwork and creeping into broken soil among the interim storage 19c of portion of bucket 19a and stone.When vacuum unit 102 work, the broken soil among the 19c of portion of storage temporarily and stone are drawn into casting pipe 105 and it is stored in the loading bin 104, by the way say, purified in filter element 103 by 102 inhaled airs of vacuum unit.In this case, creep into the broken soil and the stone that draw off the interim storage 19c of portion of bucket 19a from the earthwork and be stored in the loading bin 104, take out from derrick with regard to the bottom of available suitable mechanism opening loading bin 104 and pulverize soil and stone.Other beneficial effect is similar to the above-mentioned effect that is obtained among first embodiment of auger of creeping into according to the present invention.

Below, the 3rd embodiment that creeps into auger according to the present invention will 23 be illustrated in conjunction with the accompanying drawings.

In the 3rd embodiment, one as the drilling tool on the lower-limit point of removable unit 21 that is installed in the second rig unit 8, and a roller bit 106 that creeps into ground 1 by swing roller is installed in cubic metre of earth creeping on the appropriate location of bucket 19a of above-mentioned second embodiment shown in Figure 22.Remaining structure is similar to the corresponding construction of second embodiment shown in above-mentioned Figure 22.Above-mentioned constitute creep into auger also can be in ground accurately ground auger dig a target borehole 7a.

In above-described first to the 3rd embodiment, guide rod is so to constitute, and can be divided into a plurality of parts to it.Target borehole 7a creep into the short place of distance, configurable (assembling) but do not contain the guide rod 7 of this separate section.

In addition, above-mentioned first to the 3rd embodiment respectively is provided with the hydraulic cylinder 60 as the mechanism that drives the extensible plate 61 of fixed mechanism.But, might adopt such structure, a promptly configurable motor replaces hydraulic cylinder 60, installation such as tooth bar or the such switching mechanism of like and makes the rotation of motor be transformed into linear movement and can extensible plate 61 can be advanced or retreat by this switching mechanism.Say that by the way four fixed mechanisms then are installed in forward and backward a, left side and the right position on the horizontal plane.But, only there are two fixed mechanisms to arrange only have three fixed mechanisms to arrange by mutual opposed relationship by spaced apart relationship.If required, fixed mechanism more than five or five also can be installed.

In above-described first to the 3rd embodiment, all disposed load cell 77, angle biography degree device 93 and distance (spacing) sensor 94.But, because can not relying on these detection signals basically, target borehole 7a do not crept into high vertical precision, therefore might they designs there be the embodiment of these sensors 77,93,94.

In addition, in each of above-described first to the 3rd embodiment, hydraulic motor 20 all is housed as fixed mechanism.The layout that substitutes these hydraulic cylinders 20 is a motor.

In above-described first to the 3rd embodiment, bucket 19a, drilling tool or vacuum unit 102 are crept in the earthwork be arranged to casting mechanism.But, might dispose facing to the broken soil of drilling area and stone jet compressed-air actuated mechanism and facing to this pulverizings soil and stone winding-up compressed air with they eliminatings.Replace as another kind, the mechanism of water pressure soil also can be set.

Because creeping into boring method and creeping into boring according to the application's claim 1-35 Machine be designed to can be by above-described target borehole wall and guide rod bear and creep into Reaction force, the rig unit that bores the pick target borehole can be made into one do not require itself bear big Creep into structure reaction force, small-sized and light. Therefore, creeping into drilling machine can be by the profile chi Very little ground little and in light weight is consisted of. For creep into drilling machine be transported to creep into on-the-spot required Work be easier, therefore, can reduce and creep into required operation quantity, thereby so that have May creep into drilling machine with tradition compares and can reduce drilling cost.

In addition, for formation has larger-diameter target borehole, only need to adjust the chi of drilling tool Very little, load onto the drilling tool consistent with the diameter of target borehole creeping into drilling machine. This is so that have May be easy in the situation of the actual size that does not need to enlarge guide rod and creep into drilling machine Creep into the target borehole of a required size. Therefore, although before the formation of big target borehole (once) be very difficult, but the large diameter target borehole that has about 3 to 4 meters can be on ground Constructed in the base.

What understand as mentioned above is such, has become suitable appearance to creeping into on-the-spot carrying work Easily, the formation of 3 to 4 meters large diameter target borehole in the left and right sides can be accomplished. Therefore, though Once finished by the manual institute of creeping into before the boring of right basis, but crept into boring according to of the present invention Method and creep into the basis boring etc. that drilling machine also can be applicable to the power transmission tower in many mountain areas Form. Creeping into boring method and creep into drilling machine and be applied in many mountain areas according to of the present invention The formation of basis boring of power transmission tower etc. the time, creep into the efficient of operation and can be carried significantly High.

In addition, creeping into reaction force can be by wall and the guide rod of above-described target borehole Bear. This is so that might limit and reduce the pendulum that creeps into drilling machine between operational period creeping into Moving, thereby might limit the central axis that creeps into drilling machine with respect to the center of target borehole The misalignment of axis, and also the drilling machine run-off the straight is crept in restriction, so that target borehole can pen Directly formed along the guide rod extension. Therefore, on horizontal plane basically not Need to adjust and creep into the dimensional orientation of drilling machine, thereby make the control when creeping into operation Become and be easier to. Compare with conventional art, the boring method that creeps into according to the present invention can be effective Ground forms the boring with more accurate perpendicularity.

Particularly according to the creeping in the drilling machine of claim 21, drilling tool creeps into for the earthwork and digs Bucket, this earthwork is crept into bucket and also be can be used as casting mechanism. The casting operation can be by promoting and falling The earthwork of suspension status is crept into bucket and is effectively reached. Roughlly speaking, do not need to dispose other Casting mechanism. Therefore, creep into the discharge operation that drilling machine can improve the soil that gets out and stone Validity, and be economical, this is because creep into the required number of components of structure of drilling machine Can keep lessly.
