Description

{STRUCTURE FOR PROTECTING LANDSLIDE}

The present invention relates to a retention structure, and more particularly, to a retention structure provided at the rear of a retention structure to be installed in the ground, wherein the retention structure and the reinforcing pile are connected by a connecting member to be fixed, Thereby minimizing the size of the retaining structure.

A retaining structure refers to a structure such as a wall that resists water pressure such as earth pressure or ground water for the purpose of preventing the collapse of the ground or the ground of the surrounding ground during the crushing of the crushed area for the foundation work.

Conventionally, a strut method, an earth anchor method, a soil nail method, a raker method, and the like have been used as a method of supporting the earth retaining structure.

If the excavation area is increased, the length of the strut is lengthened, so that buckling of the joint and distortion of the strut can cause the surrounding ground to settle down due to the deformation of the retaining structure.

The ground anchor method and the soilless nail method have the problem that ground anchor and sole nail construction can not be done when the underground water level is low and the grouting effect is small and there is not enough room at the boundary of the ground such as the underground floor of the adjacent building have.

In the case of the lacquer method, if the depth of excavation is deep, the buckling problem due to the long-term interaction of the lacquer member occurs, and the possibility of wall displacement and subsidence becomes high.

Also, the increase of the number of reinforcing stages and the construction of the intermediate pile cause a problem that the workability is lowered and the construction cost is increased.

Therefore, in the conventional method of supporting the retaining structure, when the excavation area is large, the buckling phenomenon and twisting occur due to the long conversation of the strut, and there is a fear of the settlement of the surrounding ground and due to the installation work of the lacquer, strut, and anchor, There is a problem that cost and air are increased.

Disclosure of Invention Technical Problem [8] In order to solve the problems described above, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a soil- And to prevent the occurrence of overall displacement of the retaining structure.

It is another object of the present invention to provide an earth retaining structure capable of enabling excavation work even if a structure is located around the earth retaining wall and reducing air and construction cost.

The earth retaining structure according to the present invention comprises: an earth retaining wall inserted into the ground; A reinforcing file installed at a predetermined distance behind the earth retaining wall and inserted into the ground at predetermined intervals; And a connecting member connected between the retaining wall and the reinforcing pile and spaced apart from each other by a predetermined distance in the vertical direction.

In addition, one end of the connecting member is coupled through the through hole formed in the earth retaining wall body, and the other end of the connecting member is coupled through the through hole formed in the reinforcing pile.

The reinforcing file may be a concrete file or a steel pipe file, and the connecting member may be a reinforcing bar, a PC strand, or a steel bar.

According to the present invention, the reinforcing pile is installed in the back of the retaining wall, and the retaining wall and the reinforcing pile are supported by a plurality of connecting members, thereby dispersing the earth pressure and suppressing the occurrence of overall displacement of the retaining structure.

Also, the earth retaining structure according to the present invention is easy to construct and can shorten construction cost and construction period.
