By installing the assembly for splicing multiple structures in the device, the close combination between each structural unit can be ensured, and multiple structural units can be stably connected together to form a whole, continuous structural system, improving the rigidity and strength of the overall structure.

[0030] Referring to Figure 1 With Figure 2 , positioning hole 8 is used to ensure that the foundation pit support structure can be accurately installed when the bearing column 9 is set, the positioning hole 8 not only simplifies the alignment process, but also reduces the error when installing the bearing column 9, the bearing column 9 can bear the pressure of the foundation pit wall and the surrounding soil after entering the inside of the positioning hole 8, preventing the foundation pit from collapsing.
