MANAGING SYSTEM FOR WEAK GROUND CONSTRUCTION WORK, MANAGING APPARATUS FOR WEAK GROUND CONSTRUCTION WORK AND A MANAGING METHOD OF MANAGING APPARATUS FOR WEAK GROUND CONSTRUCTION WORK}

The present invention relates to a construction management method by the management system for the soft ground treatment method, the management system for the soft ground treatment method, and the management system for the soft ground treatment method.

The soft ground treatment method is a method for compacting the ground before building a structure where the ground is soft, for example, a mud flat, and includes a sand drain method and a paper board drain method. There are various construction methods, and in particular, the PBD construction method has been widely implemented at home and abroad due to its simple construction and low construction cost. Therefore, the conventional soft ground treatment method will be described taking the above P.B.D method as an example.

In the PBD method, a continuous cardboard (95 mm wide and 3 mm thick) is pressed into the ground containing a lot of moisture, such as a tidal flat, into the ground, and the excess water in the soft ground species is absorbed through the drain board. It is a method of forcibly discharging to the ground by capillary phenomenon and loading of upper fill.

The press-in of the drain board wound on the roll is a mandrel (or also called caching) mounted on the leader of a movable endless tracker and a vibro hammer (or hydraulic motor) forcing the mandrel to a suitable depth. )

FIG. 1 schematically shows a situation in which the above general P.B.D method is being performed.

In general, the P.B.D method is based on the following procedure.

1. Move the endless track tractor 11 to the selected working position.

2. The inclination of the trackless tractor 11 and the leader 12 is properly maintained. (The mandrel is mounted on the leader and placed in the ground with the same inclination as the inclination of the leader. Usually, the inclination of the leader is ground. Have a slope of 2 degrees or less on a line perpendicular to

3. The drain board 14 wound on the roll 13 is bitten by the mandrel 15 to perform the press-fitting process. (The drain board is attached to the anchor plate provided at each press-fitting work at the end of the hook-shaped mandrel. Are bitten)

4. After pressing the drain board 14 to a suitable depth (for example, 50 m), the mandrel 15 is drawn out. At this time, the anchor plate and the drain board 14 remain in a press-fit state, but in general, when the mandrel 15 is drawn out, the drain board 14 retreats a predetermined length along the drawn mandrel 15. do.

On the other hand, for the accuracy of the PBD method (such as the vertical indentation depth and the depth of the indentation depth of the drain board), a management system for grasping the construction situation and notifying the user to the appropriate operation is required, Such a management system is conventionally used to detect the indentation depth of the mandrel, the current sensor for detecting the amount of current flowing into the vibrohammer for indentation of the mandrel or the hydraulic pressure of the hydraulic motor for indentation of the mandrel Any one of the oil pressure sensor to sense, and the management system that receives the information detected from the sensors and displays in analog form.

However, the management system as described above has the following problems.

First, since the inclination of the leader was not managed by the management system, the accuracy of the indentation construction was reduced by performing the construction work by judging whether the indentation inclination of the mandrel was appropriate.

Second, since the primitive weight is used to detect the inclination of the tractor during the movement of the tractor, the tractor driver judges the inclination of the tractor as an approximation and moves the tractor, and a considerable weight compared to the tractor body. Since the degree of inclination of the leader is judged by snow, there is a high risk of the tractor overturning when the tractor moves.

Third, it was difficult for the user to grasp the exact state of the indentation construction by displaying the information detected from the detectors in an analog form.

Fourth, it was easy to reduce the accuracy of the construction by determining whether the construction is defective by guesswork without accurate measurement of whether the indentation construction of the drain board is within an appropriate range value.

Fifth, the drawing work was mobilized by the mobilized manpower to draw out the poorly constructed drainboard, which resulted in the slowing of construction work and the waste of manpower.

Sixth, by performing the memorized construction order by the operator, it was possible to bring about the inconvenience and smooth construction progress according to the memory of the operator.

Seventh, due to the wear of the circular pulley mounted on the transmitter for detecting the indentation depth of the mandrel, the indentation depth detected by the transmitter has a predetermined error compared to the actual indentation depth, thereby reducing the accuracy of construction.

Eighth, the zero point of the mandrel indentation depth is continuously disturbed at every indentation construction. In this case, it is difficult to make more precise construction because the user sets the zero point to the eye mass to measure the indentation depth of the mandrel.

Ninth, individual detailed work data could not be obtained for the work hole in which the drain board was press-fitted. In particular, in the case of testing the press-fitted construction at a predetermined position in order to investigate the ground in advance, detailed information for each worker (underground depth may vary depending on depth, and other working conditions may vary. In this case, there was no information over time for each depth and it was common to have only data on the results of the work.

The present invention, in order to solve the problems described above, the management system for the soft ground treatment method that can accurately grasp the position of the mandrel to accurately determine the indentation depth of the mandrel, the management system applied to the management system and the It is to provide a construction management method by the management system.

Characterized in that it comprises a.

Hereinafter, with reference to the drawings will be described a preferred embodiment according to the present invention.

2 is a block diagram of a management system for a soft ground treatment method according to an embodiment of the present invention.

2, the management system for the soft ground treatment method according to an embodiment of the present invention, the tractor inclination detector 21 for detecting the inclination of the tractor 11, and the leader 12 of the tractor 11 After being indented together with the reader inclination sensor 22 for detecting the inclination of the gradient, the transmitter 23 for detecting the indentation depth of the mandrel 15 mounted on the reader 12, and the mandrel 15 The amount of current flowing into the retracting length detector 24 for detecting the retracting length of the drain board 14 which is retracted by the drawing of the mandrel 15 and the vibrohammer used for press-fitting the mandrel 15.

Figure 3 shows the appearance of the management system 300 according to an embodiment of the present invention applied to the management system, Figure 4 shows a block diagram of the management system 300 of FIG.

3 and 4, the management system 300 according to the embodiment of the present invention applied to the construction management system of FIG. 2 is connected to the case 31 and the various detectors forming an appearance, and the case 31. 4), the main controller 33a which commands the exhibition by analyzing the information received from the various sensors through the connector 32, and receives the information from the various sensors. The control unit 33, which is composed of an auxiliary control unit 33b capable of digitally converting information to the main control unit 33a and exchanging information with the main control unit 33a, and connecting the main control unit 33a. And a monitor 34 which is an exhibition unit capable of displaying information analyzed by the main control unit 33a, and connected to the main control unit 33a and stored in the storage space 35a in the case 31. Instruction of a user (not shown) to the main control unit 33a A keyboard 35, which is an input device capable of inputting a matter, and a wired connection to the auxiliary control unit 33b, which can input a user's instructions to the main control unit 33a in parallel with the keyboard 35. It is connected to the remote control unit 36 which is an auxiliary input device, the main control unit 33a, and is connected to a storage unit 41 for storing information analyzed by the main control unit 33a, and the main control unit 33a. A driver 37 for storing the information analyzed by the main control unit 33a on a separate diskette, and a printer connected to the main control unit 33a and outputting the information analyzed by the main control unit 33a as a document. And an alarm unit 39 connected to the auxiliary control unit 33b and generating an alarm sound when information received from the plurality of detectors is out of a range of a reference value previously set by the user through the keyboard 35. ) And the control unit 33 and monitor 34 It is operated by a separate power source and is configured to include an inclinometer 40 that can receive and display information from the leader slope detector and tractor slope detector.

The reason why the control unit 33 is divided into the main control unit 33a and the auxiliary control unit 33b is to make the analysis work of the main control unit 33a more smoothly. According to an application example, the main control unit and the auxiliary agent may be used. The fisherman may be integrated into one control unit.

Hereinafter, the P.B.D method by the management system for the soft ground treatment method and the management system 300 applied to the management system according to the present invention will be described with reference to the drawings.

The user manipulates the keyboard 35 of the management system 300 to input an appropriate numerical value required for the construction work according to the measurement items of the chart displayed through the monitor 34 as shown in FIG. Instructs it to remember it and act accordingly. In FIG. 4, the measurement column and the measurement range column are already programmed columns, and the design value setting column, alarm setting value column and alarm sound column are fields to be input by the user. (Of course, the chart of FIG. 4 is an example. ).

First, in the DEPTH design value setting column, an appropriate indentation depth of the mandrel 15 to be indented is input, an appropriate indentation depth range is input in the alarm set value, and a check is made in the alarm sound column. In general, since the work is mechanical and various situations at each ground point are different, it is very difficult for the mandrel 15 to be press-fitted precisely to the same depth in response to the input numerical value. Therefore, set the minimum appropriate range that includes the appropriate numerical value in the alarm set value, and if it is out of this proper range, it will be regarded as poor construction and the alarm will be sounded through the alarm unit. will be.

Second, input the proper indentation depth of the drain board 14 in the design value setting column of PAPER, input the appropriate indentation range of the drain board 14 in the alarm setting value column, and then enter the drain board 14 in the alarm sound column. If the indentation depth of) is out of the appropriate indentation range input whether or not to generate an alarm sound to inform the user. As such, the reason for inputting the proper indentation depth value of the mandrel 15 and the appropriate indentation depth value of the drain board 14 is that when the mandrel 15 is drawn after being press-fitted with the drain board 14, the drain Since the retraction of the board 14 generally occurs, the indentation depth of the mandrel 15 and the depth in which the drain board 14 is actually indented do not coincide most of the time.

Third, in the design value setting column of the SPEED, an appropriate indentation speed of the mandrel 15 is input, and an alarm setting column and an alarm sound column are similarly inputted. In general, the mandrel 15 is poured by vibro hammer or a hydraulic motor, where the indentation speed is high where the ground is weak, and the indentation speed is low where the ground is strong. Therefore, the user calculates the appropriate indentation speed of the mandrel 15 by examining the degree of weakness and strength of the ground before construction. However, when the indentation speed of the mandrel 15 is faster than the calculated proper indentation speed, the probability of poor construction can be great because the mandrel 15 is bent in the ground due to the ground resistance. Therefore, checking the indentation speed of the mandrel 15 is a necessary matter required for accurate construction.

Fourth, enter PRES or AMPERE. At this time, in order to press-fit the mandrel 15, it inputs to AMPERE when a vibro hammer is used, and checks and inputs to PRES when using a hydraulic motor. Therefore, input appropriate design value, alarm setting and alarm sound. In general, it is necessary to pre-investigate the ground, but since there is an invisible situation, hard ground may be constructed unexpectedly below a predetermined depth. In this case, the user may not be forced to press the mandrel 15 up to the preset press-in depth value of the mandrel 15. Therefore, in order to grasp the resistance pressure of the ground applied to the mandrel 15, it is necessary to detect the hydraulic pressure of the current sensor 25 or the hydraulic motor flowing to the vibro hammer.

Fifth, inputting the inclination of the tractor 11 and the leader 12, which is the XY coordinate plane and the point where the mandrel 15 is pressed into (0,0) point the tractor 11 And inputting an appropriate design value set value, an alarm set value, and an alarm sound value for the degree in which the reader 12 is inclined from the axis perpendicular to the XY axis, that is, the inclination of the "X" axis and the inclination of the "Y" axis (Fig. In Fig. 5 the slope input column of the tractor is shown as the BASE column).

Sixth, in the design value setting column of the BACK, an appropriate value of the drain board 14 that is retracted by a predetermined degree when the mandrel 15 is drawn out is input, and an alarm set value and an alarm sound column are input. In general, since the drain board 14 is press-fitted by the mandrel 15, the maximum indentation depth of the drain board 14 coincides with the indentation depth of the mandrel 15. However, since the drain board 14 is retracted to some extent as the mandrel 15 is pulled out later, the actual indentation depth of the drain board 14 is different from the indentation depth of the mandrel 15. Therefore, the user needs to determine the indentation depth of the mandrel 15 in view of the actual indentation depth of the drain board 14, and needs to set an appropriate indentation depth of the mandrel 15, and the drain board 14. It is necessary to analyze the indentation depth of) separately.

Seventh, after drawing the mandrel 15 in the BACK TIME column, the drawing motor 26 is operated to input a predetermined time for applying the drawing force to the drain board 14. This is to apply the drawing force to the pressurized drain board 14 for a predetermined time so that the drain board 14 can be properly indented. If the drain board 14 is drawn by the drawing force for a predetermined time as described later, the drain board 14 must be completely drawn out or rebuilt because it is poorly constructed.

Eighth, enter any other necessary information and press the Save key.

Of course, the above input items may have more input columns as necessary.

Before or after inputting the appropriate numerical value as described above, the user determines the construction order and inputs it through the keyboard 35. The input of the construction sequence can be made by selecting a coordinate automatic setting input for selecting an automated work sequence that has already been programmed in several forms, or by selecting a manual setting input for setting the order of the tasks manually.

First, the automatic coordinate setting input is input through a chart displayed on the monitor 34 as shown in FIG. 6A. Select and enter one of the various types (A type, B type, C type .....) already programmed in the job type column, and the number of lines for press-in construction in the job number column. In the example, it is 3 lines), and then enter-if you want to move the job in the A-> D direction for odd increase / decrease and + for D-> A direction. In the next initial coordinate input column, if a coordinate to be initially constructed is selected and inputted, the work order and coordinates are automatically displayed in the left column of FIG. 6A.

On the other hand, as shown in FIG. 6B, the manual setting input of coordinates is input by setting the construction order one by one from the first construction coordinates to the last construction coordinates, and also pressing a storage key after inputting a required column.

In addition, the user needs to perform a test and pulley setting to calculate the degree of wear of the circular pulley 23a provided on the transmitter 23 for detecting the indentation depth of the mandrel 15. In FIG. 7, the transmitter 23 as described above is illustrated. In general, the circular pulley 23a has a circumferential length of 153 cm, and the mandrel 15 is press-fitted 50 cm when the circular pulley 23a is turned around. However, when the circular pulley 23a is worn out due to long use of the transmitter, the circumferential length thereof becomes short. For example, when the mandrel 15 is press-fitted about 10m, the circular pulley 23a rotates 20 wheels and thus the press-in depth sensed by the transmitter 23 is 10m, but it is normal if the mandrel 15 is actually used. Even though the indentation depth is 10 m, when the circular pulley 23a turns 24 wheels and the transmitter detects the indentation depth of the mandrel 15 as 12 m, wear of the circular pulley 23a occurs. That is, in the case of the normal transmitter 23 without the wear of the circular pulley 23a, if the actual indentation depth of the mandrel 15 is 10 m, the transmitter 23 will detect the indentation depth as 10 m, but the wear of the circular pulley 23a will not occur. If the transmitter 23 is generated, even if the actual indentation depth of the mandrel 15 is 10m, the transmitter 23 will detect that 12m is pressurized.

Therefore, when the wear of the circular pulley (23a) as described above, the user must input the instruction to determine the 12m value detected by the transmitter 23 as 10m in order to determine whether the correct construction. Of course, this input is conveniently input by a predetermined chart displayed through the monitor 34. Therefore, when the pressurized construction of the actual mandrel 15, the control unit 33, if the information received from the transmitter 23 is 12m in consideration of the instructions entered by the user, that is, the wear of the circular pulley 23a The actual indentation depth of the mandrel 15 is calculated, and the calculated indentation depth of the mandrel 15 is displayed on the monitor 34. Of course, since it is 10m when detected as 12m, all the indentation depth values detected by the transmitter 23 are calculated and displayed in a value calculated by the ratio of 12:10.

In addition, enter other items necessary for indentation management.

After setting the default value and inputting the user's instructions and instructions to the management system 300, the following specific construction work is performed. In the actual construction work, various necessary management is made through the remote control 36 is connected to the auxiliary control unit 33b by wire for convenience of work rather than the keyboard 35.

I. Movement of the tractor 11

First, when the user presses the coordinate view button through the remote controller 36, the monitor 34 of the management system 300 displays the coordinates according to the construction order previously input by the user as described above with reference to FIGS. 6A and 6B. Accordingly, the user drives the tractor 11 to move to the coordinates according to the construction order. One example of the coordinates according to the construction order displayed on the monitor 34 is shown in FIG. The black portion represents the coordinates at which the current work is to be performed, and the dashed-dotted portion represents the coordinates at which the next construction is to be performed. Of course, depending on the application may be to choose a different color. This clear marking is used to display the coordinates of the current construction and the coordinates of the next construction so that the user can easily distinguish them from other coordinate points. It is easier to identify compared to the location.

On the other hand, during the movement of the tractor 11, the user can turn on only the inclinometer 40 power of the management system 300 (of course, depending on the application example, take a configuration such that all the devices of the management system is operated by one power supply). Although, the present embodiment may allow the inclinometer to be operated by a separate power source from the monitor and the control unit as described above in order to prevent unnecessary operation of the monitor and the control unit and the consumption of power. Inclinometer 40 connected to tractor inclination sensor 21 and reader inclination sensor 22 displays the inclination of tractor 11 or leader 12 according to the user's choice (of course, tractor and reader depending on application) Can also be configured to display all the slopes of At this time, while the user checks the inclination of the tractor 11 and the leader 12, the user performs an operation to prevent the tractor 11 overturning, and moves to the construction coordinate point corresponding to the construction order.

II. Adjusting the Slope of the Tractor 11

After moving to the construction position, the inclination of the tractor 11 is adjusted. The inclination of the tractor 11 is to perform a stable construction work after balancing the entire equipment before the indentation construction.

First, the user turns on the total power of the management system 300 to operate the control unit 33 and the monitor 34 and then display the inclination of the tractor 11 through the remote control 36. The display of the monitor 34 may be displayed as a two-dimensional graph with digital information according to the user's selection as shown in FIG. 9A.

9A, the current tractor 11 has a slope of 0.71 degrees on the X axis, and a slope of 0.50 degrees on the Y axis. On the other hand, the point indicated by the dashed line is the inclination limit value of the tractor 12 required for proper work, if out of this the user needs to fit the inclination of the tractor 11 within the range of the dashed line.

III. Matching the Slope of the Reader 12

After the inclination of the tractor is adjusted, the inclination of the leader 12 is adjusted. The inclination of the leader 12 determines the inclination in which the mandrel 15 is press-fitted, and the inclination in which the mandrel 15 is press-fitted determines the inclination in which the drainboard 14 is press-fitted. Determination is necessary for proper indentation.

First, the user displays the inclination of the reader 12 through the remote control 36. The display of the monitor 34 is displayed as shown in Fig. 9B.

Similarly, the point indicated by the dashed line is the inclination limit value of the leader 12 necessary for proper work, and if it is out of this, the user may change the inclination of the leader 12 through the leader inclination adjusting device provided in the tractor 11. It needs to fit within range. In general, as described in the prior art, it is preferable that the inclination of the leader 12 is within a range of 2 degrees in a line perpendicular to the ground for proper construction work, so that the limit value indicated by a dashed line is also within a range of 2 degrees. Do.

On the other hand, since the inclination of the tractor and the leader may have a mutual influence, depending on the application example, it is also possible to float the tilt of the tractor and the leader at the same time by floating Figure 9a and 9b in one window.

Ⅳ. Indentation Construction

If the inclination of the reader 12 is appropriate, the user presses the drain board 14. This press-in construction is examined in order.

1. Displaying Work Status Chart

At this time, the user to display the work situation chart that can display the information detected from the various sensors on the monitor 34 at a time through the remote control 36.

This chart is as shown in FIG. 10 or FIG.

First, FIG. 10 will be described from the left.

In the DEPTH, the indentation depth of the mandrel 15 detected from the transmitter 23 is analyzed and displayed by the controller 33. Therefore, the indentation depth of the mandrel 15 is displayed numerically in the compartment displayed digitally, and the indentation depth of the mandrel 15 is displayed in the bar graph at the lower side thereof. At this time, the control unit 33 will be displayed by analyzing the information detected from the transmitter 23 in consideration of the wear of the circular pulley (23a) as described above.

PAPER refers to the actual indentation depth of the drain board 14. Therefore, in the cell that is displayed digitally, the actual indentation depth of the drain board 14 is limited to the length in which the drain board 14 is retracted when the mandrel 15 is drawn out from the indentation depth of the mandrel 15. On the lower side, the indentation depth of the mandrel 15 is displayed in a bar graph. At this time, the control unit 33 wears the circular pulley 23a on the information detected from the retracting length detector 24 for detecting the retracting length of the drain board 14 when the mandrel 15 is drawn as described above. In view of the degree, the analysis will be displayed.

In the APERE, the controller 33 analyzes the detected value from the current sensor 25 for sensing the amount of current flowing to the vibrohammer for placing the mandrel 15 and displays it in real time according to time. Of course, when the hydraulic motor is used for placing the mandrel 15, the PRESSURE column is displayed and the hydraulic pressure is displayed.

X is the X-axis inclination of the reader 12, Y is the Y-axis inclination of the reader 12, the control unit 33 analyzes and displays the value detected by the leader inclination sensor 22 in real time.

The SPEED is displayed in real time with the indentation speed of the mandrel 15. As described above, the indentation depth of the mandrel 15 and the rotational amount of rotation of the circular pulley 23a of the transmitter 23 are proportional, and the rotation speed of the circular pulley 23a and the indentation of the mandrel 15 are also proportional to each other. Since the speed is proportional, the control unit 33 can determine the indentation speed of the mandrel 15 by analyzing the speed at which the circular pulley 23a of the transmitter 23 rotates and the degree of wear of the circular pulley 23a. And these values are displayed.

The B / PAPER exhibits the length of retraction of the drain board 14 upon drawing of the mandrel 15.

The user can display a work situation chart in which the above values are displayed on the monitor 34 to check the work status according to the current construction at a glance, and immediately determine whether the construction is defective.

In general, digital information can be displayed to the user by displaying a sophisticated value, but when the numerical value is continuously changed for a very short time, the analog graph notation is more useful to the user and has the advantage of accurately identifying the information. That is, while the construction work is completed, it is convenient for the user to be displayed by digital information, but in the situation where the construction work is in progress, it is more convenient for the user to display in analog form. Therefore, the management system 300 according to the present embodiment displays them in parallel so that the advantages of the analog and digital displays can be utilized.

FIG. 11 shows a part capable of exhibiting the indentation speed of the mandrel 15, a part capable of displaying the front mouth depth of the drain board 14, and a retraction length of the drain board 14 in the work situation chart as described above. The parts that can be omitted are omitted, and the rest are as described above with reference to FIG. 10.

On the other hand, the work situation chart according to the construction completion at each construction time is stored in the storage unit 41. This work situation chart is useful when the user needs situation data for a specific construction. This is because, as shown in FIG. 10 and FIG. 11, in the present work situation chart, the ground resistance pressure, the slope and the like at each point of the ground are analyzed and displayed in real time as the construction work progresses by the control unit. For example, if you want to carry out soft ground work for a certain area, you need to test the construction of several points in order to know the ground information of that area. In this case, the ground situation of each point of the ground is analyzed in real time, and the analyzed information is recorded in the work situation chart and stored in the storage unit 41, so that the user later outputs it and needs information for actual work (drain The indentation depth of the board, the indentation speed of the mandrel, etc. can be extracted.

2. Indentation Process

The user who floats the above work status chart on the monitor 34 performs the press-fitting construction of the drain board 14 in earnest.

First, the proximity sensor 28 detects the zero position at every press-fitting operation of the mandrel 15, and the controller 33 sets the zero position by the information received from the proximity sensor 18. Therefore, the indentation depth of the mandrel is calculated from the zero setting.

The vibrohammer pours the mandrel 15, and the mandrel 15 begins to be pressed into the ground together with the drain board 14 which is bitten by the anchor plate provided at the end thereof.

At this time, in the work situation chart, various numerical values according to the current work situation that changes with time start to be input.

In addition, if the user is out of the range of the appropriate numerical value previously input during the construction work, the warning unit 39 may sound a warning sound.

3. Mandrel (15) Drawing Process

When the mandrel 15 is press-fitted to a set appropriate value, the mandrel 15 is pulled out. At this time, as described above, the drain board 14 is retracted by a predetermined degree, and the retraction length of the drain board 14 and the actual press-in depth of the drain board 14 are displayed in the working situation chart.

4. Determination of adequacy of construction and drawing out of drain board 14

When the drawing of the mandrel 15 is completed and the actual indentation depth of the drain board 14 and the like are displayed in an appropriate range in the work situation chart, as described above, the user can use the drawing motor ( 26, the drawing instruction of the drain board 14 is given for a predetermined time. Of course, depending on the application, this can be done automatically.

At this time, the tension generated in the drain board 14 by the drawing force applied by the drawing motor 26 is detected from the tension sensor 27, the control unit 33 receives this tension value to the monitor 34 Display it. If the displayed tension value is greater than or equal to the predetermined value, proper construction is achieved, and if less than or equal to the predetermined value, poor construction is performed.

Depending on the application, it may be configured to generate an alarm sound through the alarm unit 39 so that the user immediately knows whether or not the failure.

It looks at one of the drawing example of the drain board 14 according to the poor construction as described above.

The user may set an appropriate tension value of the drain board 14 in advance through the keyboard 35, and when the user pulls the drain board 14 for a predetermined time as described above, the control unit 33 receives from the tension sensor 27. If the tension value of the drain board 14 is below the proper tension value, the drawing motor 26 instructs to pull the drain board 14 continuously. In this way, the poorly constructed drain board 14 can be drawn out.

Of course, depending on the application example, the user looks at the tension value of the drain board 14 displayed through the monitor 34, determines whether the drain board 14 is defective or not, and draws the motor 26 through the remote controller 36. ) May be enabled.

As described above, when one construction work is completed, the user drives the tractor 11 to move to the next construction position.

Of course, the above-described processes I, II, and III are processes applied to each press-fitting of the drain board 14.

On the other hand, it is also possible to document and output to the printer 38 all the charts displayed on the monitor 34 as described above and charts to be able to grasp all working conditions at a glance, and also by the driver 37 It can be stored on the diskette, such output and storage can be performed by the user via the keyboard 35 or the remote control 36.

The following shows an example of the output document of the printer 38 showing all the working conditions at a glance in actual construction work (for example, Yeongjong-do airport site construction work).

When the first press is made to press the mandrel 15 to reach a certain set value, the buzzer sounds and the mandrel 15 is drawn out. At this time, the printer 38 prints as follows.

In this way, the work status is sequentially summarized according to the construction order and output as a document.

 12 shows an example of a status document outputted as a document in which work statuses are sequentially summarized as described above.

Meanwhile, the P.B.D method using the management system and the management system 300 applied thereto will be described with reference to FIG. 13 or below.

1.Calculation of the actual indentation depth of the mandrel 15 and the drain board 14 (see Fig. 13)

The user undergoes a constant experiment as described above, i.e., an experiment to find the degree of wear of the circular pulley such as when the indentation depth of the actual mandrel is 10 m and the indentation depth detected from the transmitter is indicated by 12 m. When the error occurs as the user inputs to the control unit to recognize the depth received from the transmitter 23 to 10m per 12m,

First, the control unit 33 recognizes and analyzes the user's instructions to calculate the degree of wear of the circular pulley 23a.

Second, press the mandrel (15) in accordance with the indentation construction.

Third, the zero position of the mandrel 15 is detected and set.

Fourth, by the transmitter 23 detects the indentation depth of the mandrel 15 according to the indentation construction.

Fifth, the control unit 33 calculates the actual indentation depth of the mandrel 15 in consideration of the wear degree of the circular pulley 23a calculated above to the indentation depth of the mandrel 15 received from the transmitter 23. do.

Of course, the actual indentation depth of the calculated mandrel 15 is displayed on the work situation chart displayed on the monitor 34 by the instruction of the control unit 33.

On the other hand, after calculating the actual indentation depth of the mandrel 15 as described above,

Sixth, when the mandrel 15 is drawn out, the retracted length of the drain board 14 that is retracted with the mandrel 15 to some extent is sensed.

Seventh, the actual indentation depth of the mandrel 15 and the retreat length of the drain board 14 are analyzed to calculate and display the actual indentation depth of the drain board 14.

2. Determination of proper construction and drawing of drain board 14 which is poor construction (see Fig. 14 and 15)

The drain board 14 has various possibilities to be poorly constructed. An example of poor construction of the drain board 14 is that the mandrel 15 is pressurized in the ground so that the mandrel 15 is bent so that the drain board is pressurized or loosely pressurized. And the case where the press-fitting construction is performed in a state where the inclination is not proper, and the press-fitting is performed under the set proper press-in depth. As one example of whether or not a defect is determined in the case of being loosely indented, as shown in FIG. 14,

First, drawing force is applied to the press-fitted drain board 14 through the drawing motor 26.

Secondly, the tension of the drain board 14 to which the drawing force is applied is sensed.

Third, by comparing the tension of the drain board 14 with a predetermined reference value to determine whether or not the drain board 14 is defective construction.

Fourth, if the tension value is less than or equal to the predetermined reference value, the drawing motor 26 is continuously operated. If the tension value is greater than or equal to the predetermined reference value, the drawing motor 26 is stopped.

In addition to the above-described examples, as described above, the control unit 33 analyzes the indentation depth of the drain board 14 and the like and determines whether the construction fails to reach an appropriate design value. Therefore, referring to Figure 15 is drawn out of the poorly constructed drain board,

First, the controller 33 analyzes the values sensed by the various detectors to determine whether the drain board 14 is defective.

Second, if the construction of the drain board is appropriate, the construction work will be terminated, but if it is determined that the drain board 14 is defective, the control unit 33 instructs the drawing motor 26 to fix the poorly constructed drain board 14. Command to draw.

Third, the drawing motor 26 is operated by the command of the control unit 33 as described above to draw the drain board (14).

3. Slope detection and display (see Fig. 16)

During the movement of the tractor 11 and the press-fitting construction of the drain board 14, the slope of the tractor 11 and the leader 12 is sensed and displayed in order to prevent overturning and construction of the tractor 11,

First, the inclination of the tractor 11 and the leader 12 is detected from the inclination detectors 21 and 22 of the tractor 11 and the leader 12.

Second, the inclination of the tractor 11 and the leader 12 is analyzed.

Third, the inclinations of the tractor 11 and the leader 12 are displayed in two dimensions so that the user can recognize the inclination of the tractor 11 and the leader 12.

Fourth, the user adjusts the inclination of the tractor 11 and the leader 12 while looking at the inclination of the displayed tractor 11 and the leader 12.

4. In case of exhibiting construction order (see Fig. 17)

First, the user inputs the press-fitting construction order of the drain board 14 to the control unit 33 through the keyboard 35.

Second, the control unit 33 analyzes the construction order input by the user.

Third, the analyzed construction order is displayed on the monitor 34. Here, the exhibition may be displayed in two-dimensional coordinates, as shown in Figure 8, it is preferable to display at least one or more of the current construction order or the following construction order distinguished from other coordinates.

Fourth, construction work should be carried out according to the displayed construction order.

5. Judging the indentation speed of the mandrel 15 and adjusting the indentation speed (see FIG. 18).

First, the control unit 33 determines a reference value for the appropriate rotational speed of the circular pulley 23a proportional to the proper indentation speed of the mandrel 15 according to the ground pressure of the construction area input by the user.

Second, inject the mandrel (15).

Third, the rotational speed of the circular pulley 23a is received.

Fourth, the rotation speed of the circular pulley 23a received above is compared with the reference value. Fifth, when the rotational speed of the circular pulley 23a is equal to or greater than the reference value, the indentation speed of the mandrel 15 is lowered. Here, the reference value may be given in a constant speed range, and the fourth step may be made by a separate command of a user or automatically by a controller by a program.
