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.

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.
