[0002] The main function of the reinforced structure of the inner corner of a deep foundation pit is to enhance the stability and bearing capacity of the slope of the foundation pit to avoid problems such as soil loss and structural damage. In construction and civil engineering, inner corners are usually places where problems are more likely to occur because they are usually turning points of the project and are also infiltration points for soil and water. By strengthening the structure at the inner corners, the stability and bearing capacity of the slope of the foundation pit can be increased, thereby ensuring the stability and safety of the project.

[0003] At present, after the angle of the reinforced structure of the inner corner of the deep foundation pit is fixed during use, most of them cannot quickly adjust the support angle, which makes it inconvenient to quickly support the inner corners of different angles, which can easily affect the work efficiency.
