Description

{Steel sheet pile wall structure}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel sheet pile wall structure, and more particularly, to a steel sheet pile wall structure that provides easy reuse and ease of installation and disassembly of a wall structure, and also provides a solid connection structure.

The steel sheet pile method is a method for continuously or intermittently interlocking sheet piles to form a permanent or temporary wall to serve as an earth retaining wall or a water wall by mainly restraining the lateral external force. As the method is excellent in workability, There are a wide range of applications such as quay walls, revetments, breakwaters, culverts, water walls, docks and shifts.

Typically, steel sheet piles are used as temporary structures, but when used as permanent structures, dead loads can be reduced and soil structures can be readily supported and the entire construction can be performed quickly.

These earth structures should be easy to install in the ground, and should be easy to dismantle after installation of the structure.

In addition, earth structures installed in the earth should have durability against earth pressure.

However, in the conventional soil structure, an example is shown in which a sheet pile composed of a plate or the like is combined with an "H" -shaped steel sheet. In the soil structure, deformation of a sheet pile is developed in the ground, There is a problem that reuse is impossible due to such deformation.

Also, the conventional soil structure has a problem that the soil structure collapses due to the earth pressure acting on the sheet pile during excavation process and structure construction process after installation.
