The present invention relates to a square plate pile and a wall structure using the same, and a construction method thereof, by improving the structure of the pile for the protection of concrete structures such as piers, to increase rigidity, to minimize deformation due to earth pressure, and to be pushed when the vehicle collides. This invention relates to a square board pile, a wall structure using the same, and a method of constructing the same.

In general, when building buildings, bridges, etc. in soft ground, earth walls are constructed to prevent nearby soil from falling down.

Brief description of the earth wall construction according to the prior art is as follows.

For example, when constructing shifts and piers, as shown in FIG. 1A, the temporary earth wall 1 is constructed to secure a space for the shifts A and P, and the foundation pile 2 is subjected to an excavation process. After the lower foundations are constructed with rebar, formwork and concrete, the walls and copings are constructed with rebar, formwork and concrete, and after the backfilling process, the upper structure is constructed.

That is, in the construction work, in order to form the bridges (A) and the bridges (P) of most bridges, the temporary soil wall (1) process, the foundation pile (2) process to secure the bearing capacity of the structure, the shift (A) and the pier ( It has been constructed through rebar assembly and form assembly process, concrete placing and curing process, form removal process, and backfill process to form P).

Therefore, the conventional bridges and bridge construction as described above has a problem in that a series of work processes are complicated, the quality control of each work process is difficult, the construction period is very long, and the cost of construction is not economical.

And, as shown in Figure 1b, in the case of the construction of the ground and underground three-dimensional cross-facing facilities to construct a temporary earth wall (1) to secure a space for the installation of the facility, through the excavation process, the foundation pile (2), After installing the lower slab (3) on the foundation pile (2) with reinforcing bars, formwork, concrete, the wall (4) and the upper slab (5) is constructed of reinforcing bars, formwork and concrete, backfilling, and paving.

As shown in this figure, most of the ground and underground three-dimensional intersection facilities in the construction work is the temporary earth wall (1) process to form the structure, the foundation pile (2) process to secure the bearing capacity of the structure, the ground and underground solid It has been constructed through reinforcing steel assembly and formwork assembly process, concrete placing and curing process, formwork removal process, backfilling and paving process to form cross facility structure.

Therefore, the process management of all the processes for the conventional three-dimensional cross-linking facilities as described above is difficult and the construction period is very long, there is a problem causing long-term traffic congestion.

In order to solve these shortcomings, the composite piles and the steel pile piles made by synthesizing the steel sheet piles and the steel pipe piles or the H-shaped piles are formed on the target ground to form a driving wall and a permanent wall to a predetermined depth. ) Has been proposed to construct.

As the composite pile 10 according to the related art, for example, as shown in FIG. 2A, the wing portions 12 are welded to both ends of the steel pipe pile 11 having a circular cross section, or as shown in FIG. 2B, the H-shaped pile 13. Steel sheet pile 14 is welded to the flange.

In the case of FIG. 2A, as shown in FIG. 2B, connecting rings 12a are formed at both ends of the wing part 12, and thus, the synthetic pile 10 and the upper open type steel sheet piles 15 are connected to the ring 12a. It is alternately repeated through the connection is installed, and in the case of Figure 3a type composite pile 10 and the lower open type (based on the drawing) steel sheet pile 16 is alternately connected and installed to form a wall as shown in Figure 3b.

As a specific example of the prior art, only the pier, above-ground and underground three-dimensional intersecting facilities are presented, but the conventional synthetic pile is also applied to retaining walls, walls, and the like.

The wall structure by the conventional composite pile uses the steel sheet piles (15, 16) of the circular cross-section, the steel sheet piles (15, 16) is a problem that has a high risk of bending strain and collapse because of the weak force against earth pressure applied structurally There is this.

And, as shown in Figures 2b and 3b, since the synthetic pile 10 is installed in a concave-convex shape, when the vehicle collides with the wall, it is caught on the concave portion of the wall and pushes the wall to move forward to the rear of the wall. As the wall by the synthetic pile 10 is crushed and deformed, the wall is pushed backward and the damage of the vehicle body is severe, and there is a big problem of injury to the occupants in the car.

And, because the wall by the synthetic pile 10 is a concave-convex shape, the aesthetic sensation is reduced from the visual side, and the synthetic pile 10 (steel pipe pile 11 and H-shaped pile 13) from the structural side There is also a problem that the support force against earth pressure is weak due to the shape.

In addition, the composite pile 10 (steel pipe pile 11, wing 12 or H-shaped pile 13 and steel sheet pile (14, 16)) and the steel sheet pile for the connection of the composite pile (10, As it is composed of 16), as the quantity of materials increases, there is a problem in that the cost of purchasing and manufacturing raw materials is high.

The present invention has been made to solve the above-mentioned problems, and to provide a square plate pile and a wall structure using the same and a construction method that can minimize the deflection and collapse by structurally securing the holding force against earth pressure. .

In addition, another object of the present invention is to minimize the damage caused by the collision of the vehicle to reduce the damage of the wall structure and the vehicle and to minimize the damage to life.

Another object of the present invention is to promote the visual and structural stability of the pile pile.

Another object of the present invention is to reduce the material through structural improvements.
