Immersed tube cast-in-place pile

The utility model relates to the field of pile foundations, in particular to a pipe-sinking cast-in-place pile, which solves the problems that the mode of pulling out a pile pipe while vibrating is adopted, vibration generated by the mode can cause great damage to an auxiliary device, and the service life of the auxiliary device can be shortened due to the absence of a damping structure. The outer end face of the inserting rod abuts against two symmetrically-distributed recovery damping contact mechanisms, the assembling connecting base is fixedly connected with a first hydraulic cylinder, the bottom end of the bearing base is fixedly connected with a second hydraulic cylinder, and a part of hydraulic damping driving mechanisms are arranged in the recovery damping contact mechanisms. The recovery damping contact mechanism can play a role in damping when being in clamping contact with the inserting rod, the situation that the auxiliary device is greatly damaged by generated vibration when the pile pipe is pull
