Abstract

The invention relates to a buckle pipe type pile extractor and relates to technical field of civil construction equipment. The buckle pipe type pile extractor is capable of reducing construction cost and shortening the construction period and comprises a buckle pipe and four pile pulling clamping blocks which are pivoted on the lower portions of the inner walls of the buckle pipe and can pivot vertically; the buckle pipe is a straight pipe with open upper and lower ends; the four pile pulling clamping blocks are symmetrically arranged in the circumferential direction of the buckle pipe; four limiting clamping blocks are fixed to the lower portions of the inner walls of the buckle pipe and are arranged under the four pile pulling clamping blocks correspondingly; and when each pile pulling clamping block pivots to the position where the length direction is perpendicular to the central axis of the buckle pipe, each pile pulling clamping block abuts against the corresponding limiting clamping block under the pile pulling clamping block, and the inner end of each pile pulling clamping block is located on the inner side of the corresponding limiting clamping block. The pile pulling device provided by the invention is suitable for pulling out waste pipe piles buried in the soil body.

Description

technical field [0001] The invention relates to the technology of civil construction equipment, in particular to the technology of a buckle tube type pile extractor. Background technique [0002] In the civil construction process, it is often necessary to remove the waste and old pile pipes that were originally buried in the soil. There are two main methods for removing waste pile pipes: one is the water flushing pile method, which uses high-pressure water guns to wash and dilute the soil around the waste pile pipes, and finally realizes pile pulling; the other is the full-rotation pile pulling method. In this method, a full-rotary obstacle removal machine is used to quickly rotate and cut the obstacles around the waste pile pipe, and the soil around the pile is separated from the old pile, and then the old pile is pulled out or removed. The existing methods for removing waste pile pipes require more auxiliary equipment to assist construction, and the construction steps are...
