Description

  The present invention relates to a turbid water agitation treatment apparatus, for example, agitation and separation of soil particles contained in turbid water from agitation by agitating turbid water, which is the final waste liquid generated when washing the inside of a well hole in hot spring excavation method, mud excavation method, etc. Efficient continuous processing can be performed in a short time until the discharge standard is met regardless of the amount of supply, so that the final industrial waste can be reduced in volume, etc. Moreover, the apparatus can be easily handled at the processing site.

  Conventionally, for example, cast-in-place piles as foundation work performed in civil engineering, construction, etc., underground continuous wall construction included bennite etc. that exhibit lubricity against fresh water pumped from the pump installed on the ground to the excavation site A muddy water excavation method is used in which muddy water is used as a transport fluid for excavated soil, or drilling is performed using muddy water in order to reduce excavator cooling or bit wear.

  When the quality of such muddy water is lowered, the excavation efficiency is deteriorated. Therefore, for example, the properties of the muddy water are controlled so that the viscosity, specific gravity, filtered water amount, sand fraction, PH, and the like are not more than predetermined values as indices. And if the specific gravity, viscosity, etc. become higher than necessary, and it becomes an obstacle to construction management and quality control, solid matter such as soil particles that have dissolved in the muddy water, such as specific gravity sedimentation method or centrifugal separation method, etc. By removing the water and separating it, the values of mud water viscosity, specific gravity, etc. are reduced and the excavation efficiency is improved.

  At this time, a flocculant may be mixed in the muddy water in order to increase the coagulation ability of solids such as soil particles and to improve the efficiency of the treatment.

  By the way, fresh water is used to remove the muddy water remaining in the excavation hole after the excavation by the excavator (hereinafter referred to as “residual mud water” in this specification) and clean the excavation hole. Muddy water is an industrial waste with a high soil particle content and specific gravity, high turbidity, viscosity, etc., so it is transported from a construction site to an appropriate industrial waste treatment facility by a vacuum vehicle for treatment. Processing will be performed.

  Residual muddy water in the hole is discharged from the ground to the ground by sending fresh water equivalent to the volume in the well hole into the hole by a circulation pump equipped on the ground and replacing it with the residual muddy water. The fresh water fed into the hole by this replacement work is mixed with the mud and diluted to become residual mud (hereinafter referred to as semi-mud in this specification), and still has a high mud concentration. Replacing in the same way with more than the volume of fresh water, and washing the well bore, becomes muddy water with greatly diluted mud concentration. Therefore, the semi-muddy water discharged at this time is transported from the construction site to an appropriate industrial waste treatment facility by the vacuum vehicle as industrial waste, as well as the residual muddy water, and processed.

  Then, as a method and large-scale equipment and facilities for treating these residual mud water or semi-mud waste mud water and industrial wastewater that become industrial waste, a chemical solution is mixed using a mixer consisting of meandering mixing tubes and stirred. As a result, the soil particles in the mud are agglomerated and grown as flocs to a large particle size, and the centrifugal action of the centrifugal mud separator provided after the mixer separates and reduces the solids such as soil particles and moisture. The treated water after the volume is separated and separated from the solid content flows into the fresh water filtration tank and is discharged outside after filtration. In addition, the muddy water used for which the specific gravity is increased by carrying out the mud drilling method is reduced in the specific gravity by removing the soil particles by air pressure by the centrifugal action of the centrifugal separator, so that the specific gravity is reduced and stable in the mud drilling method. There is an invention which attempts to reuse as a liquid (see, for example, Patent Document 1).

  By the way, when excavating a hot spring, for example, fresh water is sent into the excavation hole after excavation by the excavator at the excavation site, and is drained to the ground by substituting the residual mud water remaining during excavation. On the other hand, the residual muddy water pumped up from the borehole was directly transported to a processing facility such as an industrial waste facility by a vacuum vehicle and processed.

  The fresh water replaced in the excavation hole instead of the residual mud is largely affected by the residual mud during the initial cleaning. In the past, it was transported to a processing facility such as an industrial waste facility.

In addition, the clarification due to the replacement of the clear water advances by carrying out the cleaning work of the excavation hole one by one, and eventually the turbid water is transferred to the muddy water. Hauled and processed to appropriate industrial waste disposal facility. After the completion of the well bore cleaning, a submersible pump was installed to pump up the hot spring.

However, the above-described conventional invention described in Patent Document 1 is an invention mainly made up of cast-in-place piles as foundation works for civil engineering and construction, underground continuous wall construction, etc. Residual mud or semi mud that becomes industrial waste with high turbidity due to specific gravity and soil particles,
As in the hot spring excavation method, clarified water is replaced with fresh water to clean the borehole after excavation, and turbid water in which the specific gravity and turbidity of soil particles are considerably lower than the residual mud water or semi-mud water is treated. It is not a thing.

  The above-mentioned conventional invention described in Patent Document 1 is a centrifugal mud separator for separating solids such as soil particles contained in mud and moisture, and solids such as soil particles and moisture. In order to filter fresh water after separating the volume of water, a fresh water filtration tank is provided at the rear stage of the mud separator to improve the water to the last stage, and the treatment facility is enlarged and large-scale. At the same time, the installation of facilities requires a large area, so it is not suitable for installation at excavation sites. Moreover, in order to perform the muddy water operation management to the wastewater treatment function, the treatment process becomes complicated, and the equipment cost for that becomes large.

  Moreover, in the conventional invention described in Patent Document 1, a mixing liquid is used to agglomerate soil particles in the muddy water by mixing and stirring the chemical solution with respect to the muddy water, thereby facilitating separation of the soil particles and moisture. The mixer is a structure that is meandered and fixedly laid in front of the centrifugal mud separator, so it cannot be easily attached and removed, and it takes a lot of time and effort to replace it with a new one. In short, maintenance and inspection could not be performed easily.

  Moreover, since the mixing pipe used in the mud excavation method described in Patent Document 1 needs to have a constant treatment efficiency, it can be used only within a range in which the amount of muddy water to be treated is assumed in advance. However, in order to cope with various processing amounts, the versatility is low, so the use is limited.

  The present invention solves the above-mentioned conventional drawbacks, and uses, for example, turbid water that becomes the final waste liquid at the time of washing in the well hole after completion of hot spring excavation work in the hot spring excavation method or benite mud water having lubricity as a transport fluid for drilling soil The specific gravity of soil particles such as turbid water that becomes the final waste liquid for well bore cleaning in the mud drilling method, as well as turbid water containing concrete cutting powder discharged from construction sites and construction sites such as road and building demolition For turbid water whose turbidity is much lower than that of residual or semi-mud water, stirring can be carried out efficiently in a short period of time without imposing a heavy human load, regardless of the amount of supply. In addition, the separation of solids and water contained in muddy water and the release of moisture that conforms to the release standards at the construction site are also possible, making it possible to easily reduce the volume of industrial waste. Waste treatment The equipment is greatly reduced and the equipment is downsized, making it easy to carry in, install, operate, and carry out equipment at the processing site, simplifying handling operations, and making the structure simple and The purpose is to facilitate the assembly and to reduce the manufacturing cost and the equipment cost.

Are attached to the mounting substrate 1 substantially in parallel with the non-use state A (see FIG. 3), and the straight pipe parts 5, 5, 5,. It is characterized by comprising fastening means 11 which is attached to the use state B (see FIGS. 1 and 2) by being rotationally displaced in the R-shaped curved pipe portion 6 with respect to the substrate 1 at a desired angle θ.

  A flowing water hose 2 is connected to the inlet 3a, and a drainage hose 4 is connectable to the outlet 3b.

  Further, the outer shape of the agitating tubular body 8 is substantially S-shaped by the straight pipe portions 5, 5, 5 and the R-shaped curved pipe portions 6, 6 as shown in FIGS. However, the stirring tubular body 8 is not limited to that shown in the figure, and the stirring tubular body 8 is formed by meandering a plurality of times by increasing the number of installed straight pipe parts 5 and R-shaped curved pipe parts 6. You can also.

In the first embodiment, the stir tubular body 8 is assumed to have a turbid water treatment amount of 30 to 40 m ³ in hot spring excavation, and the maximum continuous treatment amount is set to 300 m / min, and the straight pipe portions 5 and 5 are used. , 5 and the R-shaped curved pipe portion 6 with a pipe diameter φ equivalent to 100 mm is adopted. However, the pipe diameter φ between the straight pipe portion 5 and the R-shaped curved pipe portion 6, The length R and the curvature R1 of the R-shaped curved pipe portion 6 are not limited to those shown in the figure, and are arbitrarily set.

  In order to attach the stirring tubular body 8 to the mounting substrate 1, the fastening means provided with the support plates 10, 10 provided so as to be fastened facing the left and right sides of the support groove 9 so that the stirring tubular body 8 can be clamped. For example, 11 is a bolt / nut 11A. The bolt / nut 11A may be of a turnbuckle type.

  Further, the tightening means 11, 11 of the first embodiment includes an R-shaped curved pipe portion 6 into which the first tightening means 11 located at the lower portion is inserted into the support groove portion 9 and the straight pipe portion 5 thereabove. The second tightening means 11 arranged in the inner region and located immediately above is arranged so as to sandwich the straight pipe portion 5 located second from the bottom by the first tightening means 11. It has become.

  From the flowing water hose 2 connected to the inlet 3a, the turbid water W pumped up from the excavation hole K to the ground tank T1 is to be treated in the stirring tubular body 8 by the other submerged pumps P1, P2 for transporting turbid water. Is supposed to be transported.

  Further, a line L ′ for conveying the turbid water W1 (fluid) after the continuous stirring treatment by the stirring tubular body 8 is connected via the drainage hose 4 connected to the outlet 3b, and the turbid water W1 after the treatment is usually dedicated. To the storage tank T2. And in this storage tank T2, solid substances, such as a soil particle, will settle and isolate | separate from a water | moisture content.

  At this time, the solids and water separated already in the storage tank T2 are not mixed with the solids and water separated again by pouring into the storage tank T2 of the muddy water W1 after the processing in which the solid water W1 is continuously conveyed thereafter. Thus, by providing a partition plate not shown in the figure, it is possible to maintain a continuous solid precipitation state. T3, T4, and T5 are settling tanks that are continuously provided downstream of the storage tank T2.

  Then, the water W2 after the solid matter such as soil particles settled and separated is finally excavated by another submersible pump P3 if there is no problem with the discharge regulations set by each municipality. Released on site. Further, the solid matter finally remaining in the precipitation tank T2 or the like again is put in, for example, a bag and dried, and an industrial waste treatment is requested from the supplier for disposal.

  Moreover, even when the flow rate of the turbid water W flowing into the stirring tubular body 8 from the inlet 3a is small, the stirring plate 7 is formed by twisting a large number of direction changing plates 7A in the circumferential direction and twisting them in the axial direction. In order to exhibit a certain level of agitation function, the straight pipe portion 5, 5, 5 is attached to the mounting substrate 1 substantially in parallel as shown in FIG. 5, 5, 5 are rotated and displaced in the R-shaped curved pipe portion 6 by a desired angle θ with respect to the mounting substrate 1, and the straight pipe portions 5, 5, 5 are vertically erected to be used in the usage state B. Therefore, the turbid water W flowing into the stirring tubular body 8 from the inlet 3a disposed above can be obtained even when the turbid water W flowing into the stirring tubular body 8 has a flow rate that is considerably smaller than the prescribed amount. Is a non-use state A in which the straight pipe portions 5, 5, 5 are mounted substantially parallel to the mounting substrate 1. Compared to the above, the agitation tubular body 8 is uniformly filled and flows uniformly inside the agitation tubular body 8, and the flowing direction is changed by the direction change plate 7A of the agitation plate 7, so that the agitation function is sufficiently exerted. Is done.

  And chemical | medical solution D1, D2 is inject | poured in the stirring tubular body 8 from the postscript chemical | medical solution injection port 12a, 12b, respectively.

  Among these, the chemical liquid D1 for aggregation is injected from a plurality of chemical liquid inlets 12a provided near the inlet 3a through which the muddy water W flows, and from the chemical liquid inlets 12b provided near the outlet 12b on the opposite side. For example, a chemical liquid D2 for solid-liquid separation such as soluble calcium chloride dissolved in water is injected.

  In the turbid water stirring device of the first embodiment, the chemical solution D1 for aggregation injected from the chemical solution injection port 12a provided in the vicinity of the inlet 3a of the stirring tubular body 8 has a certain degree of viscosity. Therefore, the stirring tubular body 8 from the vicinity of the inlet 3a to the vicinity of the outlet 3b of the stirring tubular body 8 is obtained in order to obtain a sufficient stirring function by uniformly and uniformly mixing the chemical solution D1 with the turbid water W in the stirring tubular body 8. The agglomeration by the chemical solution D1 is promoted by utilizing the substantially full length of the above and promoting stirring.

  The chemical liquid D2 for solid-liquid separation is injected from the chemical injection port 12b provided in the vicinity of the outlet 3b of the stirring tubular body 8 because the flocs aggregated after the solid-liquid is separated by the coagulation action of the chemical liquid D1 for aggregation. In order to prevent the solid matter from being finely broken again by the stirring action by the stirring plate 7, the chemical solution D2 is soluble calcium chloride dissolved in water, and has a low viscosity and good permeability, so it is connected to the vicinity of the outlet 3b. This is because the solid-liquid separation is sufficiently promoted in the drain hose 4 at the latter stage.

  Moreover, in the turbid water stirring apparatus of the first embodiment, the stirring tubular body 8 has the straight pipe portions 5, 5, 5 and the R-shaped curved pipe portions 6, 6 as shown in FIGS. 1 and 3, for example. Therefore, the stirring effect of the stirring plate 7 depends on the fluid velocity, and is essentially stirred even when turbid water W flows from the inlet 3a and from the outlet 3b. Even if the muddy water W flows in, stirring is performed.

  By the way, in the first embodiment, in the state of use B, it is not shown in the vicinity of the inlet 3a for the adjustment of the amount of the chemical solution D1 at the beginning of use or the flow rate adjustment when the maximum processing amount of the muddy water W is exceeded. In order to simplify the mounting of the stirring tubular body 8 on the assumption that the flow rate adjusting valve is equipped, the turbid water W is directly converted into the turbid water W by the use state B with the inlet 3a of the turbid water W facing upward and the outlet 3b facing downward. A sufficient agitation effect can be obtained if it flows in the agitating tubular body 8 through the descending-ascending-descending path with respect to the pipe parts 5, 5, and 5 and the passing flow rate is equal to or greater than an allowable amount.

  However, when the amount of the turbid water W flowing into the stirring tubular body 8 becomes small, the stirring tubular body 8 is installed in an upside down manner with the outlet 3b as the inlet and the inlet 3a as the outlet. When the body 8 is attached, the turbid water W flows in the stirring tubular body 8 along the ascending-descending-rising path with respect to the straight pipe portions 5, 5, 5, and even when the passing flow rate becomes small, The turbid water W is uniformly filled in the stirring tubular body 8, and the stirring action is maintained as a whole.

  Reference numerals 12a and 12b denote chemical liquid inlets provided in a desired number near the inlet 3a and the outlet 3b of the stirring tubular body 8. In the illustrated first embodiment, the chemical liquid inlets provided near the inlet 3a. From 12a, the chemical | medical solution D1 for coagulating and promoting the solid substance of the muddy water W which flows in from the said inlet 3a is inject | poured. The turbid water W that flows from the chemical inlet 12b provided near the outlet 3b, is agitated by the agitating plate 7 while passing through the agitating tubular body 8 and is agglomerated and changed by the chemical D1. Is injected with a chemical solution D2 that separates the solid into water and moisture.

  And the chemical | medical solution D1 which retains a certain amount of viscosity by inject | pouring the chemical | medical solution D1 for aggregation from the chemical | medical solution injection port 12a provided in the vicinity of the inlet 3a of the stirring tubular body 8 causes the stirring tubular body 8 to have a stirring tubular shape. The substantially entire length of the stirring tubular body 8 from the vicinity of the inlet 3a to the vicinity of the outlet 3b of the body 8 is utilized to mix uniformly and uniformly with the turbid water W by the stirring action by the stirring plate 7, and the chemical solution D1 is sufficiently stirred. Aggregation due to is promoted.

  Further, the drainage hose 4 in the subsequent stage removes the solid content and moisture of the turbid water W that has already been aggregated and changed in the stirring tubular body 8 by the chemical liquid D2 injected from the chemical liquid injection port 12b provided near the outlet 3b. Separation inside is promoted, continuous turbid water W can be treated, and the treatment efficiency is improved.

  At this time, the injection amount of the chemical liquids D1 and D2 is adjusted depending on the specific gravity of the turbid water W to be processed by passing through the stirring tubular body 8 or the input amount of the turbid water W to the stirring tubular body 8.

  Reference numeral 13 denotes an air introduction port provided at a proper position of the stirring tubular body 8. The air introduction port 13 introduces air into the stirring tubular body 8 and mixes it with turbid water W flowing into the stirring tubular body 8. This is to promote stirring of the turbid water W in cooperation with the stirring plate 7 by the water bubbles formed.

  Embodiment 1 of the turbid water stirring treatment apparatus according to the present invention has the above-described configuration. In Embodiment 1, the stirring tubular body 8 has an outer shape as shown in FIGS. 5 and the R-shaped curved pipe portions 6 and 6 are connected to each other by meandering a plurality of times in a substantially S shape, and a large number of direction change plates 7A are provided around the stirring tubular body 8. A stirring plate 7 formed by being slightly displaced in the direction and twisted in the axial direction is inserted in the longitudinal direction.

  When the agitating tubular body 8 is not in use, an R-shaped curved pipe portion 6 adjacent to the mounting substrate 1 is slidably inserted into a support groove portion 9 provided on the mounting substrate 1, and The agitating tubular body 8 is inserted between the support plates 10 and 10 erected on the left and right sides, and a plurality of the support plates 10 and 10 are provided so as to be fastened with different heights h1 and h2. The agitation tubular body 8 is attached to the mounting substrate 1 as a non-use state A in which the straight pipe portions 5, 5, 5 are installed substantially parallel to the mounting substrate 1 by tightening the tightening means 11, 11. 3).

  In the first embodiment, for example, a bolt / nut 11A is used as the tightening means 11, so that the tightening operation can be easily performed by performing a screwing operation.

  In use, the tightening means 11, 11 is first loosened, and then the R-shaped curved pipe portion 6 of the stirring tubular body 8 inserted in the support groove portion 9 is rotated around the tightening means 11 in the support groove portion 9. By moving and displacing, the straight pipe portions 5, 5, 5 arranged substantially parallel to the mounting substrate 1 in the non-use state A are erected vertically with a desired angle θ with respect to the mounting substrate 1 and displaced.

  At this time, the displacement operation of the agitating tubular body 8 is performed by sliding the R-shaped curved pipe portion 6 while being guided in the support groove portion 9, and the R-shaped curved pipe portion 6 adjacent to the mounting substrate 1. The agitating tubular body 8 is supported by the support plates 10 and 10 erected on both the left and right sides of the support groove 9 so as to be pivoted and displaced about the tightening means 11 that can be tightened between the left and right sides. Therefore, the displacement operation by one person can be performed quickly and reliably by a simple handling operation.

  Then, by tightening the tightening means 11 and 11 again, if the left and right side surfaces of the stirring tubular body 8 are sandwiched between the support plates 10 and 10 that are opposed to each other, the stirring tubular body 8 is The straight pipe portions 5, 5, and 5 are raised from the non-use state A by the desired angle θ with respect to the mounting board 1, and the mounting state is displaced to the use state B and attached to the mounting board 1 (FIGS. 1 and 2). reference).

  Thus, when the turbid water W pumped up from the excavation hole K to the ground tank T1 is conveyed through the flowing water hose 2 into the agitating tubular body 8 by the separate flowing water pumps P1, P2 for conveying muddy water, the turbid water W is mixed with the agitating tubular body 8. A large number of direction change plates 7A are slightly displaced in the circumferential direction and twisted in the axial direction and agitated while being changed in flowing water direction.

  When the chemical liquid D1 for aggregation is injected from the chemical liquid injection port 12a provided in the vicinity of the inlet 3a of the stirring tubular body 8, the chemical liquid D1 having a certain degree of viscosity is stirred in the stirring tubular body 8. By using the substantially entire length of the stirring tubular body 8 from the vicinity of the inlet 3a to the vicinity of the outlet 3b, the turbid water W is uniformly and uniformly mixed by the stirring action by the stirring plate 7, so that sufficient stirring is performed. Aggregation of soil particles and the like in muddy water W by D1 is promoted.

  Moreover, as described above, the chemical liquid D2 injected from the chemical liquid injection port 12b provided near the outlet 3b aggregates and changes the solid content and moisture of the turbid water W aggregated and changed in the stirring tubular body 8 by the subsequent stage. Separation in the drainage hose 4 is promoted, continuous turbid water W can be treated, and the treatment efficiency is improved.

  At this time, the injection amount of the chemicals D1 and D2 is adjusted by adjusting depending on the specific gravity of the turbid water W to be processed or the inflow amount of the turbid water W into the stirring tubular body 8.

  Further, in the turbid water stirring treatment apparatus according to the first embodiment, the stirring tubular body 8 includes the straight pipe portions 5, 5 from the non-use state A in which the straight pipe portions 5, 5, 5 are attached to the mounting substrate 1 substantially in parallel. , 5 are rotated and displaced in the R-shaped curved pipe portion 6 at a desired angle θ with respect to the mounting substrate 1, and the shape is changed to the usage state B, so that the straight pipe portions 5, 5, 5 are attached to the mounting substrate 1. Therefore, even when the flow rate of the turbid water W flowing into the stirring tubular body 8 from the inlet 3a is considerably smaller than the specified amount, the stirring tube is formed from the inlet 3a disposed above. The turbid water W flowing into the body 8 is uniformly filled in the agitating tubular body 8 as compared with the non-use state A in which the straight pipe portions 5, 5, 5 are attached to the mounting substrate 1 substantially in parallel. It flows evenly and is sufficiently stirred while the direction of flowing water is changed by the stirring plate 7.

  And even if the said chemical | medical solution D1 itself has a certain amount of viscosity by inject | pouring the chemical | medical solution D1 for aggregation from the chemical | medical solution injection port 12a provided in the inlet_port | entrance 3a vicinity of the stirring tubular body 8, even if the said chemical | medical solution D1 itself has a certain amount of viscosity, Utilizing substantially the entire region of the stirring tubular body 8 from the vicinity of the inlet 3a to the vicinity of the outlet 3b, the chemical solution D1 is uniformly and uniformly mixed in the turbid water W by the stirring function of the stirring plate 7 in the stirring tubular body 8 and sufficiently stirred. Therefore, aggregation by the chemical solution D1 is promoted.

  When a chemical liquid D2 for solid-liquid separation, such as soluble calcium chloride dissolved in water, is injected from a chemical injection port 12b provided at the outlet 3b of the stirring tubular body 8, the stirring plate 7 is already in the stirring tubular body 8. The agglomerated floc solid substance of the turbid water W being mixed and stirred by the stirring solution 7 is not finely broken again by the stirring action of the stirring plate 7, and the outlet 3b has a low viscosity and good permeability. The solid-liquid separation between the soil particles and the water is sufficiently promoted in the drainage hose 4 at the subsequent stage connected to the.

  Moreover, in the stirring apparatus of the first embodiment, the stirring tubular body 8 is substantially composed of straight pipe portions 5, 5, 5 and R-shaped curved pipe portions 6, 6 as shown in FIGS. 1 and 3, for example. S-shaped compactly formed, the stirring effect of the stirring plate 7 depends on the fluid velocity. Essentially, even if a fluid such as turbid water W flows from the inlet 3a, the stirring is performed and the fluid flows from the outlet 3b. Can be stirred.

  By the way, in the present embodiment 1, in the state of use B, it is shown in the drawing provided in the vicinity of the inlet 3a for the adjustment of the amount of the chemical solution D1 at the beginning of use and the flow rate adjustment when exceeding the maximum processing amount of the turbid water W1. In order to simplify the installation assuming that there is no flow rate adjusting valve, the turbid water W has a straight pipe portion 5 due to the use state B with the inlet 3a of the muddy water W facing upward and the outlet 3b facing downward. , 5, 5 through the lowering-upward-lowering path and flowing through the agitating tubular body 8, and a sufficient agitation effect can be obtained if the passing flow rate is equal to or greater than an allowable amount.

  However, when the amount of turbid water W flowing into the stirring tubular body 8 becomes small, when the outlet 3b of the stirring tubular body 8 is used as the inlet and the inlet 3a is used as the outlet, the top and bottom are mounted in the reverse mounting state. Since the turbid water W flows in the agitating tubular body 8 along the ascending-descending-rising path with respect to the straight pipe portions 5, 5, 5, the turbid water W is agitated tubular body even if the passing flow rate becomes small. 8 is uniformly filled and the stirring action is maintained as a whole.

  Therefore, the aggregation of the solid matter such as soil particles by the chemical solution D1 injected from the chemical solution injection ports 12a and 12b into the stirring tubular body 8 and the separation of the solid matter such as the soil particles and moisture by the chemical solution D2 are effectively exhibited. Thus, the continuous muddy water W is processed with high processing efficiency.

  Further, if air is introduced into the stirring tubular body 8 from the air inlet 13 provided at a proper position of the stirring tubular body 8, the turbid water W flowing into the stirring tubular body 8 is stirred by the stirring plate 7 by water bubbles. In cooperation with the turbid water W and the chemical solution D1, the mixing and mixing are facilitated.

  And the density | concentration with respect to the turbid water W of the chemical | medical solution D1 inject | poured in the stirring tubular body 8 is mixed uniformly uniformly, aggregation of solid substances, such as soil particles by the chemical | medical solution D1, is accelerated | stimulated, and the soil particle | grains by the chemical | medical solution D2 in the latter stage, etc. Since the solids and the water are effectively separated and the turbid water W can be processed continuously, the turbid water W can be processed with high processing efficiency.

  In this way, the turbid water W1 after being stirred by the stirring tubular body 8 is transported to the normal dedicated storage tank T2 as shown in the figure. And in this storage tank T2, solid substances, such as a soil particle, settle and isolate | separate from a water | moisture content.

  At this time, the solids and water separated already in the storage tank T2 are not mixed with the solids and water separated again by pouring into the storage tank T2 of the muddy water W1 after the processing in which the solid water W1 is continuously conveyed thereafter. Thus, by providing a partition plate not shown in the figure, it is possible to maintain a continuous solid precipitation state.

Then, if there is no problem in the discharge regulation, the water W2 after the solid matter in the storage tank T2 has finally settled excavates a large amount of water from which solid content such as soil particles contained in muddy water has been removed. Discharge treatment can be performed on site, and industrial waste can be greatly reduced.
In addition, solid matters such as soil particles that have finally settled at the bottom of the precipitation tank T2 and other tanks T1, T3, T4, and T5 are dried in a bag, for example, and processed by an industrial waste disposal company. Request.

  Moreover, what is shown in FIG. 6 shows Embodiment 2 of this invention.

It arrange | positions so that the straight pipe part 5 located in the 2nd position from the bottom may be pinched | interposed by this 1st fastening means 11 being arrange | positioned in the inner region of the pipe part 6 and the straight pipe part 5 above it. The second tightening means 11 positioned immediately above the first tightening means 11 has substantially the same configuration as that of the first embodiment.

  However, in the second embodiment, the fastening means 11 positioned with the third height h3 different from the bottom is further provided with the straight tube portion 5 positioned second from the bottom and the straight tube portion 5 positioned third from the bottom. By supporting the lower surface of the third straight pipe portion 5 from the bottom by the configuration arranged in the inner region, the first, second, and third tightening means 11, 11, 11 are tightened. From the non-use state A in which the pipe parts 5, 5, and 5 are attached substantially parallel to the mounting board 1, the straight pipe part 5 is rotationally displaced with respect to the mounting board 1 at a desired angle θ ', tightened, and used. The other configurations are the same as those in the first embodiment, and the other operations are the same.

  In the above description, for example, after the completion of the hot spring excavation work in the hot spring excavation method, the case where the turbid water that becomes the final waste liquid at the time of cleaning in the well hole is agglomerated / separated, etc. has been representatively explained. In addition, for example, muddy water that uses lubricated benite mud water as a transport fluid for excavated soil, turbid water that is the final waste liquid for well bore cleaning, and also discharged from general civil engineering sites such as roads, building demolition, and facility construction The present invention can also be applied optimally when solid content such as fine soil particles contained in muddy water containing concrete cutting powder is aggregated and separated from moisture.

  In the above description, the case where the agitating tubular body 8 is mounted on the upper surface of the mounting substrate 1 has been described as a representative example. However, this is merely an example and the mounting substrate 1 is not shown in the figure. When installed on the upper side, the agitation tubular body 8 is attached to the attachment substrate 1 so as to be suspended from the lower surface, or when the attachment substrate 1 is installed vertically, the attachment substrate 1 The case where the agitating tubular body 8 is cantilevered and attached to the side surface is also within the scope of application of the present invention.

  The present invention is, for example, a muddy water drilling method in which muddy water that becomes the final waste liquid at the time of cleaning in the well hole after completion of the hot spring drilling method in the hot spring drilling method or a mud water having lubricity is used as a transport fluid for drilling soil. The muddy water that becomes the final waste liquid for cleaning in the borehole, as well as muddy water containing concrete cutting powder discharged from civil engineering sites and construction sites such as roads, building dismantling, construction sites, etc. For muddy water that is considerably lower than semi-mud water, the stirring process can be carried out efficiently in a short period of time without imposing a large human load and regardless of the amount of supply. Moreover, separation of solids and water contained in muddy water and the release of moisture that meets the release standards at the construction site are also possible, making it possible to easily reduce the volume of industrial waste, and thus industrial waste.
