The present invention relates to a drain board construction apparatus for injecting a drain board for drainage into the ground for the improvement of the soft ground, and more particularly, to accurately detect the progress of the process in real time and based on this, various driving units to suit the construction conditions. The present invention relates to a drain board construction device capable of high-quality construction that can complete work under precise computer control and can automatically and quickly respond to various emergency situations to maximize construction quality and safety.

Plastic Board Drain (PBD) is one of the soft ground improvement methods for early settlement and strength improvement of soft grounds such as sapphire. By embedding, the ground water is discharged to the ground through the drain board to strengthen the soft ground. Specifically, in the plastic board drain method, the drain board is inserted into the lifting casing, the lifting casing is introduced into the ground together with the drain board, and then the lifting casing is drawn leaving only the drain board, and then the top of the embedded drain board. By cutting at the surface part, the drain board is left in the ground.

In the plastic board drain method, the depth of the boundary between the soft ground and the hard ground of the lower layer is irregular throughout the construction section, and unexpected rock, rock, etc. exist in the soft ground, so that the depth of penetration of the drain board, Penetration pressure, slope of drain board, etc. should be properly controlled according to the topography and characteristics of soft ground. In addition, the drain board must be deeply penetrated from a few meters to several tens of meters in the ground, which is invisible to the driver's eyes. Coping is very important for improving construction quality.

Conventional countermeasures considering the above requirements are disclosed in Republic of Korea Patent No. 10-044906 (Application No. 10-2003-0082830), Patent No. 10-0482623 (Application No. 10-2002-0077590), Utility Model Registration No. 20-0337187 (Application No. 20-2003-0028376), Utility Model Registration No. 20-0337188 (Application No. 20-2003-0028379), Utility Model Registration No. 20-0396374 The publication (application number 20-2005-0018712) etc. are variously disclosed.

The techniques disclosed in the above publications measure process progresses such as the verticality (inclination) of the reader, the penetration depth, the penetration pressure, and the amount of rise of the drain board using various sensors and then display them on the monitor of the cab. Or trigger an alarm, allowing the driver to accurately understand the construction situation and take appropriate action accordingly.

However, in the drain board construction method (apparatus) disclosed in the related art including the above publications, it can be said that there is some improvement in that the driver can accurately grasp the progress of the process. It is only displayed on the monitor, and all the actions to recognize the situation and take necessary actions must be done directly and manually by the driver's will, which inevitably depends on the driver's skill or concentration. It is difficult and there are certain limitations in improving construction quality.

For example, if there is an unexpected rock in the ground or a point where the depth of the soft ground is too shallow than the predetermined depth (work specification), the elevating casing will not enter any more before reaching the predetermined depth and only the hydraulic pressure will rise. The operator should take measures such as seeing the penetration depth indication value and the penetration pressure indication value displayed on the monitor or watching (or listening to) the alarm indication and stopping the penetration action by identifying the above abnormal situation. The action to stop the penetration operation is to return the RCV lever (Remote Control Valve Lever) pulled in the penetration direction to the neutral position, and the hydraulic oil supplied to the hydraulic motor by switching the hydraulic control valve by the pilot pressure oil generated therefrom. You have to change direction. However, even if the monitor recognizes an abnormal situation, it takes a certain reaction time to actually operate the RCV lever, and the action may be delayed.However, in reality, the driver needs to observe various working conditions while working, so he can concentrate on the monitor Because of this, the situation where the display values of the monitor are recognized late occurs frequently. As a result, delays in operator action can cause intrusive pressures to rise excessively, overloading the machine and even leading to deformation or breakage.

In addition, when the penetration depth becomes deeper than the set specification at a point where the soft ground is too deep (in this case, it occurs when the penetration depth is set equal to the average value previously investigated over the entire construction area), the penetration depth of the elevating casing is increased. Frequently exceeding the set depth occurs. Even in this case, in the related art, when the depth of penetration reaches the design value (work specification) while the driver observes the monitor, the penetration should be stopped. If the driver's action is delayed, the construction cost increases due to excessive penetration.

On the other hand, when drawing the lifting casing after penetration, the operation of the lifting casing should be stopped before the top of the lifting casing reaches the upper end of the leader, and the driver on the work vehicle does not recognize this situation quickly and does not stop the operation quickly. This happens frequently. In this case, the lifting casing strongly collides with the frame or the upper roller of the leader upper end, causing damage to the lifting casing, the upper roller, the frame, and the like.

Such problems are more serious when considering the reality that the depth of the soft ground is very irregular over the entire construction section, and also when considering the human limitation that the driver cannot continue to concentrate throughout the work. In other words, the construction quality is low, the risk of accidents are high, the construction cost is increased, and a high-skilled driver is required.

In addition, when drawing the lifting casing after penetration, if the drain board fails to settle in the ground, the lifting casing comes up when the lifting casing is pulled out. However, if the amount of uplift is too high, it should be rebuilt at the adjacent point. However, in the related art, such a device for measuring the amount of rise has to be provided with a separate elastic addition device, such as a complicated structure and a high risk of failure.

The present invention has been developed to solve the above problems, it is possible to accurately complete the process while accurately calculating the process progress in real time and control the various driving units according to the construction conditions based on this, even in various emergency situations It is an object of the present invention to provide a drain board construction device capable of high quality construction that can maximize the construction quality and safety by automatically and quickly coping.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

As shown in FIG. 1, the drain board construction apparatus 2 according to the present invention, like the conventional general drain board construction apparatus, has a penetration vehicle 20 and a reader 30 mounted on the penetration vehicle. And, the front and rear angle adjustment cylinder 40 for adjusting the inclination of the leader 30, the left and right angle adjustment cylinder 50 for adjusting the left and right inclination of the leader 30, the up and down direction to the leader 30 A lifting casing 60 which is installed to be movable in a direction, a drain board supplying device 70 for supplying the drain board 10 to the lifting casing 60, and a casing driving to be described later for raising and lowering the lifting casing 60. Device 80 (see FIG. 2).

Here, the penetration vehicle 20 may be formed of a crane vehicle or an excavator. In the present embodiment, the vehicle 20 for intrusion is described as an example in which a bucket is removed from an excavator and a penetration device such as a reader 30 is installed. The actual shape of the front and rear angle adjustment cylinder 40 and the left and right angle adjustment cylinder 50 may vary slightly depending on whether the penetration vehicle uses a crane vehicle or an excavator, but includes the leader 30. The rest of the configuration is the same.

The drain board supply device 70 is provided in the middle of the drain board reel 71 in which the drain board 10 is wound, the upper roller 72 provided at the upper end of the leader 30, and the leader 30. The guide roller 73 is included.

As shown in FIGS. 2 and 3, the casing drive device 80 includes a winding drum 82 in which a casing drive wire 81 is wound and drawn up and down, and a hydraulic motor for driving the winding drum 82. (83), the lower guide rollers (84a to 84c) for guiding the wire (81) below the winding drum (82), the upper part of the winding drum (82), that is, the wire (81) at the upper end portion of the leader (30). Guiding upper guide roller 85. Since the casing driving device 80 is disposed inside the reader 30, the expression is omitted in FIG. 1.

As shown in FIG. 3, the wire 81 drawn upward from the winding drum 82 is connected to the upper side of the connection block 61 of the elevating casing 60 via the upper guide roller 85 and wound up. The wire 81 drawn out from the drum 82 is connected to the lower side of the connecting block 61 of the elevating casing 60 via the lower guide rollers 84a to 84c. After the drain board 10 is movably inserted into the lifting casing 60, an anchor 11 is installed at an end thereof so that the anchor 11 is lowered (penetrated) of the lifting casing 60. Push into the ground.

In the drain board construction apparatus 2 as shown in FIGS. 1 to 3, the drain board 10 is inserted into the lifting casing 60, and the anchor 11 is disposed at the end of the drain board 10. ) And then, when the hydraulic drum 83 is driven to rotate the winding drum 82 in one direction, the lower wire 81 is pulled to lower the elevating casing 60 to penetrate the ground. After the penetration, when the winding drum 82 is rotated in the opposite direction, the upper wire 81 is pulled to raise and lift the lifting casing 60 penetrated into the ground. At this time, since the drain board 10 is fixed in the ground through the anchor 11, only the lifting casing 60 is raised and the drain board 10 is embedded in the ground as it is. When the drain board 10 exposed above the ground is cut after the drawing of the lifting casing 60 is finished, the penetration operation of one drain board is completed. If the fixing of the drain board 10 is incomplete, the drain board 10 rises along the lifting casing 60 when the lifting casing 60 is drawn out. This phenomenon is called 'following', and when the amount of rise of the drain board 10 reaches a certain level (typically, 30 to 50 cm) or more, it must be reconstructed at an adjacent point.

Further, the drain board penetration construction device 2 according to the present invention, as shown in Figs. 1 to 3, is installed on one side of the reader 30, the reader tilt detection sensor 100 for sensing the inclination of the reader And a rise measurement device 110 for measuring an amount of rise of the drain board 10 when the lifting casing 60 is drawn, and a drain board 10 that is poured upon drawing by driving the drain board reel 71. A reel drive motor 120 for rewinding, and a penetration depth sensor 130 for measuring the rotational speed of the take-up drum 82 to sense the amount of movement of the lifting casing 60, that is, the amount of penetration and the amount of rise. The penetration depth sensor 130 may be formed of an encoder installed on the shaft of the winding drum 82.

As described above, the following measurement apparatus 110 is installed on the leader 30 between the drain board reel 71 and the upper roller 72, as shown in FIG. 4, and the lifting casing 60. When drawing, the sagging of the drain board 10 is sensed. When the rise occurs, the drain board 10 is stretched, and the amount of rise is measured by measuring the stretched amount.

More specifically, as shown in FIG. 5 and FIG. 6, the rise measurement apparatus 110 includes a fixing roller through which the drain board 10 drawn from the drain board reel 71 described above is spread over. (111), the guide groove 112 formed in the longitudinal direction of the leader 30 in the lower and lower side of the fixing roller 111, and the shaft 113a in the guide groove 112 is movable and rotated at the same time A lifting roller 113 which is installed to be movable and moves downward by its own weight as the drain board 10 extends downward through the drain board 10 passing through the fixing roller 111 and the guide; Limit switch 114 which is operated by the downward movement of the lifting roller 113 at the lower end of the groove 112 and outputs a corresponding signal, and the rising amount detection sensor for sensing the rising amount of the drain board 10 115. Here, the rising amount sensor 115 may be formed on the shaft (111a) of the fixing roller 111 may be formed of an encoder for sensing the rotational speed of the fixing roller 111.

The length of the guide groove 112 is preferably formed in a length shorter than the minimum allowable rise, so that it can be applied regardless of the construction area or construction conditions. For example, if the allowable rise amount is regulated between 30 and 50 cm depending on the construction area or condition, the length of the guide groove 112 is formed to be 29 cm or less.

The guide groove 112, the fixed roller 111 and the lifting roller 113 may be provided in the installation block (110a) is provided separately, as shown in the figure. The mounting block 110a, in which the guide groove 112, the fixing roller 111, and the elevating roller 113 are pre-installed, is mounted on the leader 30 by welding or bolting. ) Can be installed.

Such rise measurement device 110 of the present invention is implemented by the simple structure of the weight and the guide groove 112 of the lifting roller 113 without providing a separate structure such as elastic means.

When the drain board 10 comes up when the lifting casing 110 is drawn up as described above, when the lifting casing 60 is drawn out after the penetration, the drain board 10 is stretched, and the drain board 10 is When it sags, the lifting roller 113 moves downward along the guide groove 112 by its own weight. Accordingly, when the lifting roller 113 comes into contact with the limit switch 114, the rising signal increases, and when the drain board reel driving motor 120 is driven by the operating signal, the drain board 10 is drained. Rewind to reel 71. When the drain board 10 is rewound, the fixing roller 111 is rotated and measured by the rising amount sensor 115 along the rotational speed of the fixing roller 111.

A detailed operation process of the climb amount measuring apparatus 110 is as shown in FIGS. 7 to 10. That is, immediately after the start of penetration, as shown in FIG. 7, the drain board 10 is pulled up according to the lowering of the lifting casing 60 described above, and the lifting roller lowered as the drain board 10 is pulled up. 113 rises along the guide groove (112).
After the lowering casing 60 moves to the upper end of the guide groove 112 after the start of penetration, as shown in FIG. 8, the drain board 10 is continuously pulled up and lifted with the fixing roller 111. The roller 113 is rotated.
If rise occurs along the way of drawing the elevating casing 60 after penetration, as shown in FIG. 9, the drain board 10 is stretched (loose), and as the drain board 10 is stretched, the lift is performed. The roller 113 is lowered along the guide groove 112 by its own weight. At the end of the lowering of the lifting roller 113, the lifting roller 113 comes into contact with the limit switch 114. When the limit switch 114 is in contact, the penetration control module 300 receives the signal and applies a driving signal to the drain board reel driving motor 120 described above to drive the reel driving motor 120 in the rewind direction. As a result, as shown in FIG. 10, the drain board 10 wound up is rewound to the drain board reel 71. The rewinding speed of the drain board reel 71 is equal to the maximum deflection amount of the drain board 10. The maximum deflection amount 10 of the drain board 10 is calculated according to the length of the guide groove 112 and input to the penetration control module 300 in advance.

FIG. 11 shows an overall configuration diagram of a drain board construction apparatus related to the control portion and the drive portion according to the present invention.

As shown in FIG. 11, the drain board construction apparatus 2 according to the present invention includes an RCV lever 3 installed inside a cab of a penetration vehicle and generating a pilot signal in response to a driver's operation, and a penetration vehicle. The hydraulic oil pump 4 for supplying hydraulic pressure to the various driving parts of the hydraulic pump 4 and the hydraulic oil 4 to selectively supply the hydraulic oil generated from the hydraulic pump 4 by the pilot signal from the RCV lever 3 to the respective driving parts. Hydraulic control valve 5 to control.

The RCV lever 3, the hydraulic pump 4, and the hydraulic control valve 5 are basically installed in a general intrusive vehicle, that is, a crane vehicle or an excavator vehicle, and a detailed description thereof will be omitted. However, when the RCV lever 3 is selectively operated in various directions determined according to the working method, a pilot signal (pilot oil pressure) corresponding to the selected working method is generated, and the hydraulic control valve 5 is switched by the pilot signal. Thus, the hydraulic oil generated from the hydraulic pump 4 is selectively supplied to each drive unit. As described above, the driving unit may include a front and rear angle adjustment cylinder 40, a left and right angle adjustment cylinder 50, a winding drum hydraulic motor 83, a turning hydraulic motor 45, and the like.

In addition, the drain board construction apparatus of the present invention, as described above, is installed in the penetration depth sensor 130 for sensing the movement amount of the elevating casing 60, the reader 30 to sense the inclination of the reader 30 The reader tilt detection sensor 100, the lifting casing 60 includes a lift amount detection sensor 115 and a limit switch 114 for sensing the rise amount along the drain board 10 when drawing up.

In particular, a separate trip to the hydraulic control valve 5 in addition to the intrusion hydraulic pressure sensor 140 for sensing the hydraulic pressure supplied to the hydraulic drum 83 for the winding drum and the signal by the RCV lever 3. A pilot control valve 150 for providing a pilot signal to stop the hydraulic motor 83 for the winding drum.

In addition, it forms a series of signal connections with the RCV lever 3, the sensors 100, 114, 115, 130, 140 and the trip pilot control valve 150, and computes the sensing signals output from them. A penetration control module 300 for controlling a driving unit including the pilot control valve 150 for trip and a penetration control module 300 installed in a cab of the penetration vehicle according to the processing result. It includes a monitor 160 for displaying a variety of construction information including the sensing value from each of the sensors by the control of.

The penetration control module 300 is the lifting casing applied from the penetration depth sensor 130 in a situation in which an operation signal is received from the RCV lever 3 (that is, in a situation where penetration operation is in progress). The penetration depth or the draw height of 60 reaches a preset value (ie, reaches a maximum value), or the hydraulic pressure applied from the penetration hydraulic pressure sensor 140 rises to a preset value (ie, to a maximum value); Or when the reader tilt value applied from the reader tilt detection sensor 100 reaches a preset value (ie, reaches a maximum value), the operation signal from the RCV lever 3 is ignored, and The trip signal is applied to the trip pilot control valve 150 to generate a pilot signal from the trip pilot control valve 150. Then, the hydraulic control valve 5 is switched by the pilot signal to shut off the hydraulic oil supplied to the hydraulic drum 83 for the winding drum. Therefore, when the depth of penetration, pull height, intrusion hydraulic pressure, and the inclination of the leader 30 reach the maximum allowable values set at the time of work, even if the driver who does not recognize this continues to operate the RCV lever 3 in the intrusion position automatically, A trip signal is generated to immediately shut off the hydraulic pressure supplied to the hydraulic drum 83 for the winding drum. Therefore, no problem of intruding, drawing out, or raising the hydraulic pressure above the maximum allowable value does not occur, and as a result, the construction quality is improved, and safe construction without damage or damage to the equipment can be guaranteed. The maximum allowable value is set by the driver at the construction site according to the construction specification.
For example, when a trip is made by the penetration depth or the penetration pressure, the driver who recognizes the trip moves the RCV lever 3 from the penetration position to the neutral position, and the penetration is made until the operation is stopped through the monitor 160. Check depth and penetration pressure. When the penetration depth reaches the normal construction range, the penetration is made to suit the specification. After the trip is released, the RCV lever 3 may be operated in the drawing direction to perform drawing. Otherwise, if the intrusion pressure is high and it is determined that a trip has been made even though the depth of penetration has not reached the set point, the driver may no longer have the unexpected depth of rock or soft ground in the casing 60. After performing the extraction by operating the RCV lever 3 in the drawing direction without performing excessive penetration, the penetration operation is performed again to the adjacent ground.
In addition, after the trip by the drawing height is made, the driver who has recognized the trip moves the RCV lever 3 from the drawing position to the neutral position. The trip by the drawing height is made because the lifting casing 60 has risen to the set height, so that the drain board 10 exposed on the surface of the ground is cut and the work is finished.
In addition, when the inclination of the leader 30 during the construction is out of the set value, a trip is made, the driver who recognizes the trip stops all the work and refers to the inclination value of the reader 30 displayed on the monitor 160, and the RCV lever ( 3) by operating the front and rear angle adjustment cylinder 40 and the left and right angle adjustment cylinder 50, the reader 30 may be set up immediately.

The penetration control module 300 may more specifically include a signal processing module 310, a penetration construction controller 320, and a driving execution module 330.
