Construction method for withdrawal of waste pile

The invention involves a construction method of pulling-out the waste pile. The invention includes the flowing steps: aligning the pile extractor at the waste piles needed pull-out, vibrating the pile extractor with the vibrating hammer to making it sink down into soil along the pile body while casting; when the bottom of pile extractor sinks the lower of the pile tip, clipping the outer walls of waste pile with the cuneiform block on the cuneiform clipping pile machine of post extractor from out side, pulling the pile extractor up with the auxiliary withdrawal pile power equipment, turning on the hydrojet export which is installed on the side of the pile extractor bottom, slip casting while pulling up the pile to filling the hollow hole leaved by the pile body; hanging the pile body with crane after the last part of pile reaches ground surface, relaxing the cuneiform pile extractor and hanging out the next pile; filling the hole with the slurries until hole mouth after the pile body is pulled out completely. It solves the difficulty of extracting waste pile, its effect is that it completes separating pile from soil around it, clipping the pile body, pulling out the pile body, filling the pile hole using one pile extractor; it works rapidly with pollution-free, low cost and smaller disturbance and affecting of the soil, the method is easy to grasping, operating time is short, the use of power is limited, efficiency is high.
