Bottom wrapping type vibration hammer profile steel pile pulling machine and pile pulling method thereof
The invention discloses a bottom wrapping type vibration hammer profile steel pile pulling machine and a pile pulling method. The pile pulling machine comprises a Larson type profile steel rod portionand a pile sleeve; standard channel steel and open Larson type channel steel of the pile sleeve are welded in a buckling mode, a rotation shaft is arranged on two flange plates of the standard channel steel and rotatably provided with a bottom wrapping steel plate, limiting blocks are welded to the inner surfaces of the flange plates of the standard channel steel, and the bottom wrapping steel plate is provided with triangular convex strips; and the open Larson type channel steel is welded to the bottom end of the rod portion. The pile pulling machine further comprises a main guide pipe and three branched guide pipes, and the bottom end of each branched guide pipe is provided with a spraying port. The method is characterized in that the pile pulling machine sinks to the bottom of a wastepile at a time, the bottom end of the waste pile is wrapped by the bottom wrapping steel plate, and then the waste pile is pulled out at a time. According to the pile pulling machine and the pile pulling method, the construction speed is high, the efficiency is high, the structure is relatively simple, and the manufacturing cost is low.
本发明公开了一种兜底式振动锤型钢拔桩机和拔桩方法，拔桩机包括拉森式型钢杆部和桩套；桩套的标准槽钢和敞口拉森式槽钢扣合焊接，标准槽钢的两翼缘板设有转轴，转轴可转动安装有兜底钢板，标准槽钢翼缘板内表面焊接限位块，兜底钢板设有三棱凸条；敞口拉森式槽钢与杆部底端焊接；该拔桩机还包括一根主导管和三根分支导管，每个分支导管底端设有喷口；该方法的关键在于：一次性沉入到废桩底部，利用兜底钢板兜住废桩底端，然后一次性拔出。该拔桩机和拔桩方法施工速度快、效率高，且结构相对简单，制造成本低。
