[0002] Geotechnical engineering construction is a branch of civil engineering. Among various civil engineering projects, geotechnical engineering occupies a very important position. When constructing deep foundation pits in geotechnical engineering, retaining walls are often used to support them.

[0003] CN 218090898 U discloses a retaining wall for supporting a foundation pit in soil and rock, including a base plate and a protective plate hinged to one side of the base plate. Limiting frames are symmetrically installed on one side of the protective plate. An upper crossbeam and a lower crossbeam are slidably connected between the two limiting frames. A bidirectional screw is threaded through the upper crossbeam and the lower crossbeam. An inclined brace is symmetrically hinged between the upper crossbeam and the base plate. A support frame is fixedly connected to the lower crossbeam, and the inclined brace passes through the support frame.

[0004] When in use, the existing device is difficult to adjust the support angle of the retaining wall according to the different sizes and slopes of the foundation pit. Therefore, more auxiliary heightening frames and auxiliary support plates are needed to make the device fit tightly with the soil foundation pit, which makes it inconvenient for workers to install the retaining wall. Therefore, we propose a soil foundation pit support retaining wall. Utility Model Content
