The present invention relates to a retaining wall, and more particularly, to a prefabricated retaining wall structure of a building complex that is constructed in the fill site when building the building complex.

In general, the retaining wall is constructed on a naturally formed inclined surface or artificially formed inclined surface, for example, an inclined surface artificially generated due to road and railway construction, building complex development, and the like.

In other words, the retaining wall is constructed to secure a support base when the earth pressure supporting the structure is weak and there is a risk of structural destruction or an unequal settlement is expected.

Here, the retaining wall can be classified into a fill land retaining wall and an incision retaining wall according to its installation form.

The landfill retaining wall is constructed between a flat and a different flat when the floor is multi-leveled in constructing an architectural complex such as an apartment complex or an industrial complex.

In addition, the incision retaining wall is constructed between the cut surface and the construction key surface when the road is constructed in the form of crossing the mountain or when only a part of the mountain is cut off.

1 is a perspective view illustrating a retaining wall constructed on a roadside as a typical example of a construction of a conventional retaining wall.

Referring to FIG. 1, the retaining wall 100 is installed at the boundary between the inclined cut surface 200 and the construction road 300, while the retaining wall 100 forms a form to cast concrete to cut the cut surface ( 200) to support the earth pressure.

However, since the concrete retaining wall 100 has to install a relatively large concrete retaining wall 100 along the cut surface 200, material transportation to the site is difficult, and in the soft ground, there are many difficulties in the basic treatment.

In addition, the concrete retaining wall 100 has a hassle that must be carried out strict management so that surface loss due to rainwater, damage to the concrete due to load or impact does not occur until after the concrete is solidified sufficiently.

In addition, the concrete retaining wall 100 has a problem that requires a lot of manpower and cost for its construction and maintenance because it is necessary to check the crack phenomenon over time even after the construction from time to time to perform the appropriate repair work.

In particular, the concrete retaining wall 100 has a problem that it is very difficult to construct the higher the height of the cut surface or fill surface because the restriction is also followed by the height that can be constructed.

On the other hand, since the existing concrete retaining wall 100 is constructed only for the purpose of securing a support base, there is a problem that does not match the surrounding environment at all.

In other words, because the existing concrete retaining wall 100 is constructed in a structure suitable only for the purpose of preventing deformation and collapse due to the loss of soil on the land or incision site, there is a problem that does not match the surrounding environment at all.

Therefore, the present invention was devised to solve the general problems of existing retaining walls, for example, the land retaining walls constructed in the construction complex,
