[0002] Foundation pit support is a measure of support, reinforcement and protection for the side walls and surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit. Due to the rapid development of high-rise buildings in cities, underground parking lots, high-rise building burial depth, civil air defense and other needs, high-rise buildings need to build a certain basement. In recent years, due to the rapid development of urban subway projects, subway stations, local open excavation and other projects also involve foundation pit projects. In subway stations with double-line intersections, the foundation pit is 20 to 30 meters deep. Water conservancy and electricity also have the problem of foundation pit excavation for underground plants and underground pump rooms. Whether it is a high-rise building or a deep foundation pit project for the subway, since they are all excavated in the city, there are usually various structures such as traffic arteries, existing buildings or pipelines around the foundation pit. This involves a very important content of foundation pit excavation, and it is necessary to protect the safe use of surrounding structures.

[0003] However, most traditional foundation pit supports are temporary, one-time structures, which require large investments and are prone to waste.
