Description

{SOIL RETAINING METHOD}

The present invention relates to an earth retaining method, and more particularly, to an earth retaining method having improved installation, disassembly and mobility of a wale band and a bracket, excellent in field applicability, and improved installation time, convenience, and workability.

In a typical construction site, temporary earthworking is carried out in a conventional manner to prevent the earth's collapse and displacement of the excavation surface when excavating the ground for construction (civil engineering / construction site).

At this time, the support method for supporting the earth pressure acting on the back surface of the excavation is applied. In general, a strut method or an anchor method is applied.

 The strut beam method is a method of installing a wale band fixed transversely to the earth wall and supporting a earth pressure acting on the earth wall by installing a plurality of struts across the wale strips facing each other. The H-pile and the round steel pipe are applied The construction method is applied. In this method, the length of the strand should be increased according to the interval between the facing strands.

The H-Pile strut beam method, which is used most often in the construction of the temporary earth retaining structure, has no problem in connection between the struts. However, due to the difference in stiffness between the downward and leftward and rightward directions of the H- exist.

Buckling occurs in the direction of the weak axis and displacement occurs to the H-pile, so that the earth pressure on the excavation back surface can not be effectively supported. Accordingly, in order to prevent buckling, it is necessary to reinforce the horizontal and vertical stiffeners in the direction of the weak axis. Thus, it is necessary to further increase the amount of steel material and install the stiffener.

Unlike the H-Pile described above, the strut beam method using a round steel pipe has no weak axis and no strong axis, so there is no buckling problem with respect to the weak axis, so there is no need to reinforce the weak axis. However, as in the H-pile method, it is not possible for the operator to act as a passageway for moving through the strut.

Also, the work for connecting the strut can not be performed in the air where the strut is directly installed. Therefore, after assembling the strut in a separate work site, the huge strut system is installed at the installation position by lifting equipment such as a large crane. In order to dismantle the same, the same process must be performed in reverse order, There is an accident risk.

Furthermore, unlike the H-Pile strut beam method, the strut beam method using a circular steel pipe does not provide a space for rotating the bolt or nut in the bolt fastening.

Therefore, a separate bracket device, an extension fastening part, and the like must be additionally provided so that mutual connection is made through them, so that a lot of additional preliminary and preliminary work are required.

Such advance and preliminary work is pointed out as a cause of increasing the construction cost due to the occurrence of additional labor costs and the use of a large amount of steel materials as well as air delays.

The above-described technical structure is a background technique for assisting the understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.
