Problems solved by technology

The key process of drag reduction and pulling out piles is to peel off the soil around the abandoned piles to reduce the frictional resistance and achieve the purpose of pulling out the piles. Twist off, insufficient clamping force, easy to cause deformation of the drilling stripping sleeve
[0004] To this end, a device and construction method for removing pile foundations near the existing high-speed railway station building are provided to solve the problem of twisting of piles after stripping

Abstract

The invention relates to the technical field of removal of piles, in particular to a device for removing a pile foundation near an existing high-speed rail station building and a construction method.The device for removing the pile foundation near the existing high-speed rail station building comprises a removing device body, and the removing device body comprises a drilling sleeve externally connected with a drilling machine, a reinforcing protection assembly and a stripping assembly; the stripping assembly comprises inserting cones and a base rotating ring, the inserting cones are vertically connected to the drilling sleeve in an inserted mode and distributed in a circumferential array mode, and the base rotating ring is installed on the bottom face of the drilling sleeve in an assembled mode. And then the positioning cone is transversely inserted into the stripped rock layer in a vertical extrusion mode to form lateral clamping force, so that the connection strength of the pile base is reduced, the clamping force is improved, and twisting off and pulling-out are facilitated.

Description

technical field [0001] The invention relates to the technical field of pile removal, in particular to a pile foundation removal device and a construction method near an existing high-speed railway station building. Background technique [0002] Some of the newly built enclosure piles and ground-connecting wall structures overlap with the existing old enclosure piles and old engineering piles, and need to be pulled out and sealed, and the underground water head is high, and the construction is close to the high-speed railway station building, and the engineering safety risk is high. In order to ensure that the normal operation of the high-speed railway station building will not be affected during the construction of the piles, and to ensure that the ground connecting walls and the retaining piles will not collapse during the trough construction in the later stage, so as to meet the stability of the confined water, the existing pile foundations need to be sealed immediately aft...
