[0002] The foundation pit slope is prone to collapse or landslide accidents due to loss of support during the excavation process, and the foundation pit support can stabilize the slope, reduce the collapse risk and ensure the safety during the foundation pit excavation process. Meanwhile, the support structure can also provide sufficient space for the construction of basement and other foundation structures to ensure the smooth construction.

[0003] The existing foundation pit support method is to insert a plurality of baffle plates on the ground, then dig out the foundation pit in the baffle plate, and weld a plurality of connecting rods in the baffle plate to stabilize the baffle plate. This method can effectively prevent slope collapse, but when welding the connecting rod, due to the large mass of the connecting rod, only hoisting or supporting in the foundation pit method can be used to fix the connecting rod. If the hoisting method is used, the connecting rod will shake during hoisting, making it difficult to find the welding position. If the supporting method in the foundation pit is used, the connecting rod is placed on the surface of the foundation pit during the process of digging the foundation pit, and the connecting rod and the baffle plate are welded by supporting the connecting rod on the surface of the foundation pit. However, due to the poor flatness inside the foundation pit, the connecting rod is prone to tilt when placed inside the foundation pit. Both methods will increase the difficulty of welding, and if the connecting rod is not welded stably, it will affect the supporting effect. SUMMARY
