Description
According to the present invention, it is possible to prevent soil from flowing into a construction site by installing an earth retaining wall using a multi-layered high strength steel plate between a thumb pile and a thumb pile, and installing a self-supporting steel plate between the thumb pile and the self- And a method of constructing the self-supporting earth retaining structure.
As is well known, it is necessary to construct a retaining structure in order to ensure the safety of the construction work site before the construction of the structure in the various construction work such as the foundation work of the excavation of the ground to a certain depth, the joint work, and the subway construction.
The construction of such a retaining structure is carried out in order to prevent the collapse of the ground due to the earth pressure on the excavation surface or the slope, and the structure is called earth retaining walls, earth plates, earth walls and the like.
In general, in order to prevent the collapse or outflow of the soil, the H beam is fixed at a predetermined depth on the ground at a fixed interval to the edge of the ground excavation part and the cut edge of the ground excavation part, A retaining wall such as an iron plate or the like can be inserted into the retaining structure.
Accordingly, by sandwiching the H beam on the ground, the soil is excavated to a certain depth, and the earth retaining wall is sandwiched between the H beams, so that the surrounding soil can be prevented from flowing into the construction site.
If the bending strength is insufficient in comparison with the earth pressure, shear failure of the earth retaining wall occurs (breaking), and the H beam As it is separated from the flange, there is a high possibility that a large accident occurs due to the inflow of the soil to the construction site.
Therefore, in order to achieve the object of construction of the retaining structure, the retaining wall should have a bending strength corresponding to the earth pressure (i.e., compressive strength and tensile strength), and the H beam serves as a support for supporting the retaining wall do.
However, due to the limitation of the earth pressure that can be tolerated even when the earth retaining structure as described above is installed, the interior of the turf structure must be reinforced with braces or the like.
In addition, there is a problem that the number of materials is increased due to the reinforcement work of the braces, and the construction cost and the construction period are increased.
According to the present invention, it is possible to prevent soil from flowing into a construction site by installing an earth retaining wall using a multi-layered high strength steel plate between a thumb pile and a thumb pile, and installing a self-supporting steel plate between the thumb pile and the self- And a method of constructing the self-supporting earth retaining structure.
According to the present invention, the retaining wall is inserted between the thumb pile and the thumb pile, and the retaining member, which can be firmly supported and fixed to the inside of the thumb pile, is inserted into the retaining wall and then inserted. So as to provide a self-supporting type earth retaining structure capable of installing the retaining wall in a predetermined position and a construction method thereof.
Further, according to the present invention, by installing the earth retaining wall combined with the fixing member, it is not necessary to perform reinforcement works such as braces in the terra cotta work area, so that the working space inside the excavation surface can be secured more widely, To provide a self-supporting earth retaining structure capable of reducing the cost and the construction time and filling the filling material through the grouting hose between the first and second earth retaining walls to obtain the effect of grouting construction, and a construction method thereof do.
