That is, while the plurality of soil plates 31 are integrated through the fixing member 32, the soil wall 3 is assembled.

Accordingly, when installing and recovering the earth wall 3 on the foundation pile 2, the work is performed at once through an installation device such as a separate crane, so that the work is quickly performed and the workability and usability are improved.

In addition, even if a load is applied to the installed soil wall 3, the plurality of soil plates 31 are prevented from being separated without permission, so that the quality of use can be improved.

At this time, as the earth plates 31 are integrated through the fixing member 32 and the earth walls 3 are assembled and formed, unauthorized separation is prevented even when a load is applied during installation.

Therefore, the quality of use is improved.

' 형상의 '금속구조물'로 이루어질 수 있으며; 상기 고정부재(32)는, '금속와이어구조체' 또는 '금속봉구조체'로 이루어질 수 있는 것으로; 사용자의 선택에 따라 적합하게 적용될 수 있다.In the above, the fixing member 32 is bent so that both ends are located at the top, respectively, around the center.

It can be made of a 'metal structure' in the shape of a '; The fixing member 32 may be made of a 'metal wire structure' or a 'metal rod structure'; It can be applied appropriately according to the user's choice.

In addition, both ends of the fixing member 32 are bundled and bound to each other in a state in which the earth walls 3 are assembled, and later, when transported and installed through an installation device such as a separate crane, work can be performed while holding the bundled upper portion, so workability can be improved.

In the earth wall 3 for the earth wall system according to the present embodiment made as described above, the earth plate 31 may be formed with a receiving groove 312 in which the lower portion of the fixing member 32 is fitted and accommodated.

That is, as the lower center portion of the fixing member 32 is accommodated to be exposed to the lower portion of the earth plate 31, when the lower center portion of the fixing member 32 is accepted and exposed to the lower part of the earth plate 31 in the accommodation groove 312 of the earth plate 31 located at the bottom of the fixing member 32, when the ground and the lower end of the earth, As the 'gap' does not occur, structural stability can be further secured.

On the other hand, the binding holes 311 through which the fixing member 32 penetrates and binds in the soil plate 31 may be provided on the fitting recess 313 and the fitting protrusion 314; At this time, the receiving groove 312 in which the lower central portion of the fixing member 32 is accommodated in the soil plate 31 can be integrated with the fitting recess 313 and can be formed structurally simply; It can be applied appropriately according to the user's choice.

In the soil plate 31, the fitting protrusion 314 and the fitting recessed part 313 are formed at the center of the upper and lower surfaces, respectively, so that they can be fitted and bound to each other.
