[0127] During operation, the stabilizing driving part 35 is turned on, and the stabilizing driving part 35 pulls the stabilizing linkage part 36 to move, so that the stabilizing linkage part 36 pulls the movable clamping part 31 to swing. At the same time, the hinge mechanism 37 limits the movable clamping part 31, so that the movable clamping part 31 can adapt to the clamping and fixing work of assembled steel pipe piles of different specifications.

[0128] A pile foundation stabilizing mechanism 3 is provided in the present application. The clamping angle of the pile foundation stabilizing mechanism 3 can be adjusted according to the specifications of the prefabricated steel pipe pile. At the same time, the pile foundation stabilizing mechanism 3 can cooperate with the clamping plate 112 and the fixed base 111 to clamp and protect the prefabricated steel pipe pile to avoid damage to the prefabricated steel pipe pile.
