Description

The retaining wall using pile

The present invention relates to a retaining wall using a pile. More particularly, the present invention relates to a retaining wall that can be installed without restriction in a retaining wall construction zone and uses a pile firmly fixed to a drainage part.

Generally speaking, the retaining wall refers to a wall made from cutting the ground or building up the soil so that the slope does not collapse under the pressure of the soil. In other words, it is a structure made to prevent the collapse of the soil behind, and it is a structure that maintains stability by the holding strength of the retaining wall against the earth pressure behind.

These types of retaining walls are made of plain concrete and are composed of gravity retaining walls and reinforced concrete that maintain their stability by their own weight. They are composed of cantilever retaining walls, which act as cantilevers respectively, And a front wall retaining wall reinforced by providing a constant spacing wall on the entire surface of the cantilever retaining wall.

The construction of the cantilever retaining wall, which is most widely used among the retaining walls described above, will be described in detail. Once the foundation is laid, the foundation concrete is laid on the foundation. At this time, if foundation concrete is insufficient, reinforcement of ground improvement or pile is installed. After the foundation concrete is laid, the bottom reinforcement is laid and the concrete is laid. The cantilever retaining wall is completed when the reinforced concrete is placed in the concrete thus poured and the concrete is laid.

As can be seen from the case of the above cantilever retaining wall, it can be seen that the installation method of the retaining wall is completed through the complicated process including the assembly of the tearing bar, the installation of the formwork and scaffold, and the pouring of the concrete. Accordingly, there is a problem that the construction period for installing the retaining wall becomes long, the quality is changed according to the increase of the construction cost and the skill of the field worker.

To solve this problem, the prior art 10-473375 includes a PHC pile having a hollow portion at the center and a cap concrete installed at an upper portion of the PHC pile. The retaining wall thus installed is advantageous in that the land can be effectively used and the air can be shortened.

Accordingly, the work can be unified and the work efficiency can be improved.

However, since the present invention is related to a temporary structure having a purpose, effect and structure for preventing infiltration of rainwater during excavation of a subgrade, the economical efficiency and function as a permanent structure due to an increase in hydraulic pressure due to the backside There is a problem that it can not do.

In order to solve this problem, in Japanese Patent Application No. 10-1112107, it has been found that the purpose of eliminating the water pressure and reducing the water pressure on the back surface of the retaining wall through the collecting port formed integrally vertically and integrally at the center of the inner surface of the drain panel connected to the neighboring PHC pile, The PHC piles adjacent to each other must be installed at predetermined intervals without any error and it is difficult to apply the PHC pile if there is a curved section in the construction section.

In order to prevent the crushed stone aggregate (13) from coming off, a drain panel (4) sandwiched between the stoppers (3) is provided on the front surface of the retaining wall.

The drain panel 4 may be formed of a PVC plate or the like and is fitted in a region between the bent region of the stopper 3 and the crushed stone aggregate 13. [ Thereby, it is possible to prevent the crushed stone aggregate 13 from deviating to the outside as described above.

A separate square pipe 14 may be fixed to the front surface of the stopper 3 and a fixed metal piece 51 connecting the finishing panel 50 may be fastened to the square pipe 14.

The drain pipe 15 communicates the slag aggregate 13 with the drainage duct of the finishing panel-based concrete 30 provided at the lower end of the drain panel 4. [ That is, the rainwater of the ground 100 can be discharged to the outside through the pipe 5, the aggregate aggregate 13, and the drain pipe 15. therefore,

A nonwoven fabric 8 is disposed at the front end of the drain pipe 15 to prevent foreign matter such as soil from being inserted into the drain pipe 15 from the ground 100 or the crushed stone aggregate 13. [ have.

≪ Retaining wall using pile according to the eighth embodiment >

16 is a partial cross-sectional view showing a retaining wall using a pile according to an eighth embodiment of the present invention.

Referring to FIG. 16, the retaining wall using the pile according to the eighth embodiment of the present invention is different from the retaining wall of FIG. 13 according to the seventh embodiment, and therefore, a different structure will be described here. The drainage portion of the retaining wall shown in Fig. 16 includes the crushed stone aggregate 13, the drainage panel 4, and the drainage pipe 15.

The crushed stone aggregates 13 are all buried in the space on the surface of the ground 100 and there are a plurality of voids between the buried layers to allow the storm that flows in the ground 100 to pass. That is, the crushed stone aggregate 13 can be buried in the space on the front surface of the excavation surface 110, thereby improving the drainage performance and preventing the earth pressure of the ground 100 from increasing. In order to prevent the crushed stone aggregate (13) from coming off, a drain panel (4) sandwiched between the stoppers (3) is provided on the front surface of the retaining wall.

The drain panel 4 may be formed of a PVC plate or the like and is fitted in a region between the bent region of the stopper 3 and the crushed stone aggregate 13. [ Thereby, it is possible to prevent the crushed stone aggregate 13 from deviating to the outside as described above.

A separate square pipe 14 may be fixed to the front surface of the stopper 3 and a fixed metal piece 51 connecting the finishing panel 50 may be fastened to the square pipe 14.

The drain pipe 15 communicates the slag aggregate 13 with the drainage duct of the finishing panel-based concrete 30 provided at the lower end of the drain panel 4. [ That is, the rainwater of the ground 100 can be discharged directly to the outside through the crushed stone aggregate 13 and the drain pipe 15. [

A nonwoven fabric 8 is disposed at the front end of the drain pipe 15 to prevent foreign matter such as soil from being inserted into the drain pipe 15 from the ground 100 or the crushed stone aggregate 13. [ have.

The present invention is not limited to the above-described embodiment, but may be practiced in various other forms, such as those described in the following claims, It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
