The foundation pit support project is a temporary project, and the designed safety reserve can be relatively small, but it is related to the regionality. Before building a house, it is necessary to excavate the foundation pit and build the foundation. In order to ensure the safety of construction in the foundation pit, the side walls of the foundation pit need to be supported and reinforced. Protection measures such as support, reinforcement, etc., but the existing foundation pit support devices are mostly used in the process of use. Multiple reinforced concrete bodies are used as support bodies to support the single-side inner wall of the foundation pit. This kind of support structure has a small bending moment and poor ability to resist soil pressure. Utility Model Content
