[0002] When laying underground comprehensive pipe corridors, in order to ensure the safety of underground comprehensive pipe corridors and foundation pits, it is often necessary to use pipe corridor foundation pit support equipment to support and reinforce the foundation pit. The utility model patent with patent application number CN202320065430.6 discloses a pipe corridor foundation pit support structure. The laying and extension of the adjustment bottom plate are achieved through the cooperation of a folding base and an adjustment bottom plate. The adjustment bottom plate is fixed through the cooperation of the adjustment bottom plate and the accommodating base. The rotation and limitation of the adjustment bottom plate are achieved through the cooperation of a spring, a limit block and a limit groove. The soil on both sides is maintained through the cooperation of the No. 1 pile wall and the No. 2 pile wall. The simple installation of the tunnel foundation pit support structure is achieved, thereby improving the convenience of the tunnel foundation pit support structure. According to the disclosed technical solution, the existing underground comprehensive tunnel foundation pit support structure, when in use, on the one hand, when supporting the foundation pit, is often only able to support the foundation pit, and is unable to effectively tighten the foundation pit, which is prone to damage to the foundation pit and the tunnel due to outward collapse of the foundation pit, which is not conducive to further ensuring the safety of the foundation pit and the tunnel.
