The present invention relates to an earthquake structure that is installed on the side of the excavation to cope with earth pressure and to prevent the collapse of the excavated soil during the ground excavation work for the installation of underground structures such as underground pipes and sewage boxes, and the underground structure construction method using the same. More specifically, by implementing the earth block structure in which the detachable towing means is installed to install the underground structure, it is unnecessary to mobilize separate crane equipment for the towing and installation of the underground structure, thereby improving space utilization and workability, and also the underground structure The present invention relates to an earthquake structure equipped with a detachable traction means capable of controlling the width according to the installation width of the installation and to enable an active construction response to the site conditions immediately, and a construction method of the underground structure using the same.

Generally, when the ground excavation work such as building underground structures such as underground floors of buildings, subways, or dig pipes to bury underground pipes, when the well-known area is wide around the layout of the building, a sufficient angle of relief can be obtained. In the case of a site where a sufficient angle of repose is not secured due to the site conditions, the earth wall is installed on the side of the excavation to prevent the earth wall from collapsing.

The cobble wall is a temporary construction that bears the side pressure such as earth pressure and water pressure generated during the excavation work, its variety is also various bars,

First, the thumb pile earth wall is to install the earth plate between two H-piles while drilling the ground, inserting the H-pile, and then excavating. It is a method of supporting an excavation wall by inserting a earth plate while inserting or boring and inserting it into the ground and proceeding excavation.

In addition, the retaining wall is a bar that can be installed as another method of steel sheet piles, the method of installing the steel sheet piles to enable the role of the water wall and earth wall at the same time is mainly used where water-repellency is required.
