DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
With respect to wall structures applicable to retaining walls and the like, in particular, it can support various sediments such as earth and sand, industrial waste, aggregate,
The present invention also relates to a steel wall structure that can be used repeatedly. The present invention can be embodied, for example, in a cantilever type retaining wall.

[0002]

2. Description of the Related Art In a conventional civil engineering work, for example, in order to prevent collapse of an excavated surface such as a shallow foundation work, an earth retaining work for providing an earth retaining wall on the excavated surface is performed. In addition, in the cut section, the embankment section, and the like, when a soil structure or the like cannot prevent collapse, a retaining wall as a wall structure is provided to support the earth pressure. This retaining wall is provided as a retaining wall for supporting a cut-out portion and an embankment portion on a road, a residential land development site, or the like, as a revetment for a river or a harbor, and for a bridge to prevent collapse of an embankment portion around an abutment. As a conventional retaining wall,
For example, a pile-shaped bar is driven into the ground at predetermined intervals, and a plate is supported between the bars. In addition, there are a self-supporting type, an anchor type, a cutting type, and the like as the earth retaining work, and a sheet pile is used as an earth retaining wall. As the retaining wall, concrete-structured ones such as a gravity retaining wall, a leaning retaining wall, a cantilever retaining wall, a stay wall retaining wall, and a supporting wall retaining wall are also used.

[0003]

As described above, since the conventional retaining wall is constituted by a combination of a pile-shaped bar and a plate, it must be constructed on site, and the construction takes time and labor. It takes. Also, once installed on site,
Difficult to reuse elsewhere. On the other hand, since the retaining wall of the concrete structure is bulky, the transportation cost to the installation site is high, and reuse is not easy.

[0004] Therefore, an object of the present invention is to provide a wall structure that can be easily installed on site and that can be easily reused.
