The invention discloses an anti-skid clamping
mechanism based on
pile foundation pulling out and an operation method of the anti-skid clamping mechanism, and relates to the technical field of
building construction. The anti-skid clamping mechanism solves the problems that existing three-shaft stirrer refitted equipment for large
pile foundation pulling out construction has certain limitation, and the downward pressure is small; and for a
pile foundation with a large depth, the
friction force between a pile and a soil body is large, the phenomenon of insufficient lifting force exists, the construction risk is large, and the construction progress is slow. The anti-skid clamping mechanism comprises a base
assembly, stable supporting leg assemblies and a rotating support body; the number of the stable supporting leg assemblies is four, and the four stable supporting leg assemblies are rotationally connected to the four corners of the base
assembly correspondingly; and the rotating support body is rotationally connected to the inner side of the base
assembly. The anti-skid clamping mechanism and the operation method thereof, the applicability is good, the safety is high, a sleeve can be pulled out and inserted, continuous pulling out or inserting can be achieved, the pulling out and inserting force is improved, the working efficiency and
working capacity are improved, and the working adaptability and working efficiency are high.
