Generally, the vertical drainage method used for the improvement of the ground floor of a young man is to form a drainage channel to artificially promote consolidation. The vertical drainage is pressurized into the ground to drain or discharge water such as pore water contained in the ground It is one of the soft ground treatment methods to complete the settlement of the ground early and to increase the bearing capacity.

Here, the vertical drainage material is a drain board formed by wrapping a plastic core material with a porous filter material, and is a bar-shaped structure.

The vertical drainage method using such vertical drainage is referred to as PBD (Plastic Board Drain) method or PVD (Prefabricated Vertical Drain) method, and is most commonly used.

Thus, by improving the soft ground through the soft ground treatment method, it can be utilized as a basis for constructing various structures such as roads, railways, airports, ports, and industrial complexes.

In the vertical drainage method referred to as the PBD method or the PVD method, a drain board (vertical drainage material) formed by wrapping a plastic core material such as a harmonica or a honeycomb with a porous filter material is laid up to a predetermined depth in the ground, It is a soft ground improving method which enables the soft ground layer to be improved hardly by discharging the pore water around the installed drain board to the ground quickly.

This vertical drainage method is simple in equipment, relatively fast in construction speed, relatively low in material cost of drain board, and minimizes ground disturbance due to penetration of casing pipe into the ground. It is mainly applied to soft ground with high water content .

Korean Patent Publication No. 10-0204639 discloses a dredging material press-in apparatus for carrying out a PBD method. This apparatus is configured to press-fit a draining material into the ground by frictionally contacting the drein material through rotation of the press- A pair of press-fit rollers press-fit the draining material in both directions and press-fit the press-fit drape material in frictional force are arranged to be spaced by a single cylinder, so that smooth press-fitting can not be achieved due to eccentricity or the like.

In addition, in the case of the above-mentioned prior art, a reader is used for vertically arranging and supporting the draining material. However, there has been a problem that the reader has to be deformed to have a length corresponding to the length of the draining material. Since the wire rope and the driving prevention motor such as the driving drum and the driving motor are installed on the upper part of the reader for the purpose of preventing the conduction according to the vertical arrangement, As a matter of course, there is a problem that the load is transmitted to the lower part when the draining material is press-fitted into the ground.

In addition, conventionally, since the contact area between the draining material and the press-in roller is small, a casing having a pipe structure is indispensably used for press-in of the ground of the draining material, and a lifting wire and a drum for driving the casing after the press- The auxiliary pressing means is also an element which transmits a load to the reader side or adds weight to the reader side. As a result, there is a problem in that the leading edge side of the auxiliary pressing means and the auxiliary pressing means The size of the reader must be increased accordingly and the structure of the rigid structure must be secured. Therefore, the cost of the equipment is increased, and there is also a problem that it is expensive to secure the structural safety.

In addition, the drainage material to be pressed into the soft ground is about 70 m or more. In order to stably support the drainage material that is pressed into the ground, it is inconvenient and inconvenient to perform a separate foundation work, there was.

Therefore, the first and second rotary parts 200 and 220 rotatably mounted in the upper area of the frame 102, the third rotary part 400 and the fourth rotary part 400, The turning portion 420 can be brought into close contact with or spaced from the both sides of the draining material 50 by the first pressing portion 300 through the fourth pressing portion 510 precisely.

In this case, the first rotary part 200 and the second rotary part 220, which are rotatably mounted in the upper region of the frame 102, the third rotary part 400, which is rotatably mounted in the lower area, The four-turn portion 420 is configured to be spaced apart in the left-right direction by the first to fourth pressing portions 300, 310, 500, 510, respectively. The first to fourth turning portions 420, Only one pair of pivotal portions may be brought into close contact with the draining member 50 and the other pair of pivotal portions may be released from the draining member 50. [

For example, in the case where the pressure input largely affects the strength and hardness of the ground on which the draining material 50 is to be pressed, the two pairs of the rotating parts 200 and 220 (400 and 420) are brought into close contact with the draining material 50 As a result, the frictional force can be increased to increase the pressing force, and when the pressing force does not act relatively large, only a pair of the rotating parts 200, 220 (400, 420) It is possible to prevent the occurrence of the load by causing the pressing force to be brought into close contact with the human body 50 without increasing the frictional force.

That is, as shown in FIG. 6, the load sensing unit 600 for sensing the load may be disposed in the first to fourth motors 210, 230, 410, and 430 to drive the respective rotary units 200, 220, When the load detected by the load sensing unit 600 is greater than a preset value, the two pairs of the rotary units 200 and 220 (400 and 420) are closely contacted with the draining material 50 and press- When the load value sensed by the unit 600 is smaller than a preset value, only one of the pair of rotary parts 200 and 220 (400 and 420) is brought into close contact with the draining material 50, can do.

As described above, the draining material 50 is press-fitted into the ground by the friction force due to the contact by the two pairs of the rotating parts 200, 220 (400, 420) Is maintained in the vertical direction, so that it can be press-fitted into the ground without eccentricity.

The first rotary part 200 and the second rotary part 220 arranged to face the pair of rotary parts 200 and 220 (400 and 420), that is, the upper area of the frame 102 with the draining material 50 therebetween, The third and fourth rotary units 400 and 420 arranged to face the lower region of the frame 102 with the draining material 50 therebetween are arranged in accordance with the input signal of the control unit 700 The first to fourth motors 210, 230, 410, and 430 may be mounted.

Accordingly, when the first to fourth motors 210, 230, 410, and 430 are driven by the input signal of the controller 700, the first to fourth rotary units 200, 220, 400, and 420 are rotated to press the draining material 50 .

As described above, only one of the pair of rotary parts 200 and 220 (400 and 420) can be brought into close contact with the draining material 50 selectively. Therefore, in this case, the draining material 50 It is needless to say that it is possible to control rotation of only one pair of pivoting parts which are in close contact with the other pivoting parts.

For example, the first rotating part 200 and the second rotating part 220 disposed on the upper side of the frame 102 are in close contact with the draining material 50, and the third rotating part 200 and the second rotating part 220, The driving signal is inputted only to the first motor 210 and the second motor 230 in a state in which the swinging part 400 and the fourth swinging part 420 are separated from each other and released from the draining material 50 Only the first turning unit 200 and the second turning unit 220 can be rotated.

In this case, the first rotary part 200 and the second rotary part 220 are released from the contact with the draining material 50, and the third rotary part 400 and the fourth rotary part 420 are rotated A drive signal is inputted only to the third motor 410 and the fourth motor 430 so that the third rotary part 400 and the fourth rotary part 420 are driven only by the drainer 50 ) To the ground.

In the embodiment of the present invention, a pair of rotary parts disposed on both sides of the frame 102 with the draining material 50 interposed therebetween is referred to as a first rotary part 200 and a second rotary part 220 And the other pair of rotary parts disposed on both sides of the frame 102 with the draining material 50 interposed therebetween is referred to as a third rotary part 400 and a fourth rotary part 420 However, it is to be understood that the present invention is not limited thereto, and its positional relationship may be changed.

Also, in the embodiment of the present invention, at least one pair of rotary parts, preferably two pairs of rotary parts 200, 220 (400, 420) are arranged as an example, but this is also for the purpose of understanding the present invention. It is needless to say that the present invention is not limited to this, and it is needless to say that the same operation and effect can be obtained by providing a press-fitting device in which three or more pairs of pivot portions are arranged as necessary.

Referring again to FIG. 2, a guide roller 104 and a guide hole 106 are formed in a lower portion of the frame 102 to guide the draining material 50 which is vertically pushed in on the soft ground Accordingly, even when the draining material 50 is press-fitted in the vertical direction only by the pair of pivotal portions, the contact area is increased, and the supporting force can be further improved. As a result, .

In the embodiment of the present invention, the first rotary part 200 and the second rotary part 220, which are paired rotating parts, and the third rotary part 400 and the fourth rotary part, The pressing portions 300, 310, 500 and 510 are horizontally connected to the upper portion of the upper portion 420 and the lower portion of the pressing portion 300 is rotatably connected to the fixing brackets 110 and 120 by the hinges 206, It is needless to say that the positional relationship between the pair of pivots and the pair of pivotal parts may be changed in the vertical direction and the pair of pivotal parts may be formed by pressing parts 300, 310, 500, 510 and hinges 206, 206, 406, 426 may be arranged differently.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
