A limiting part 4 for supporting the central support part 3 is provided on the opposite sides of the first support part 1 and the second support part 2; the central support part 3 is fixed between the first support part 1 and the second support part 2 by the limiting part 4.

[0031] Based on the above structure, when the foundation pit needs to be supported, the first support part 1 and the second support part 2 are first inserted vertically downward into the ground slowly using a vibration device. During the insertion process, the verticality of the pile needs to be detected, and then the central support part 3 is inserted into the limit part 4 and slowly inserted into the ground to finally form a foundation pit support structure.

[0039] Based on the above structure, by arranging the second support longitudinal plate 23 at the center position of the third support transverse plate 21 and the fourth support transverse plate 22, the accuracy of the stress of the entire second support part 2 can be guaranteed, and similarly, by arranging the limiting part 4 at the center position of the second longitudinal plate, the position of the installed center support part 3 is also in the center, which guarantees the stability of the structure after subsequent assembly.

[0040] As an example, the center support part 3 can be an H-shaped connecting plate, and the center support part can include a first end plate 31, a second end plate 32, and a center plate 33; the first end plate 31 and the second end plate 32 are arranged in parallel, and the center plate 33 is arranged at the center position of the first end plate 31 and the second end plate 32;
