Retaining walls refer to structures that support roadbed fill or hillside soil and prevent fill or soil deformation. Filling is often blocked during construction to avoid landslide accidents during construction. Therefore, retaining walls are widely used in engineering construction. However, the existing retaining walls have simple structures, and most of them are set with a concrete wall. The function of the earth wall is too limited, and it cannot ensure the safety of the filling. In addition, the retaining wall mainly bears the force of the soil layer on the wall, so the lateral support of the wall is required to be firm to avoid the wall. collapse.

Utility model content

In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a retaining wall for civil engineering construction, which can improve the lateral support ability of the wall, strengthen the blocking of the soil layer, and avoid the collapse of the wall.
