In general, in order to construct the underground of civil engineering structures or structures, the excavation of excavation of the ground (earth) in the top of the earth, If the slope of the cutting surface (the surface caused by the excavation in the excavation work such as the ground) is steep and too high, the worker who works at the bottom of the slope will collapse or fall of rock So that a pile of soil is installed to prevent this.

However, since the conventional soil pile is mainly made of steel (H beam) whose section is H-shaped, it is not inserted smoothly into the ground without drilling the hole. Therefore, In this case, it is necessary to fill up the hole after the pile is inserted. Therefore, it takes a long time to work and it is difficult to construct. If the drilled hole can not be hardened, the soil film may not suppress or prevent the displacement of the pile, And the like.

In addition, when a pile is installed under the existing civil structure or building structure, the height between the ground and the bottom of the structure is less than the height of the pile, and the height between the bottom surface of the bridge top plate and the ground If the length of the pile is lower than the length of the pile, the pile can not be vertically erected due to the interference with the bridge deck. Therefore, it is difficult to penetrate into the ground and the pile should be made so that the pile .

In addition, when the construction space is narrow and the length of the pile to be penetrated into the ground is long, there is a problem in that it is difficult to penetrate the pile due to difficulty in entering and parking the crane or auger equipment.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to prevent the disturbance of the surrounding ground and the displacement and deformation of the pile by allowing the pile to penetrate directly into the ground without drilling a hole.
