The foundation pit is generally a rectangular structure, and the soil in the foundation pit is relatively loose. Support devices will be installed on the inside of the foundation pit to prevent the foundation pit from collapsing.

[0003] For example, a Chinese patent with announcement number CN220503917U discloses a structure for preventing foundation pit support from deforming, including a base plate, a baffle body hinged on the left side of the base plate, first adjustment grooves are opened on both sides of the upper surface of the base plate, second adjustment grooves are opened on both sides of the back side of the baffle body, a bracket body is movably installed inside the first adjustment groove, and the top end of the bracket body is movably connected to the inner surface of the second adjustment groove.
