Abstract

PURPOSE: To obtain the said method by a process wherein vibration and noise hardly occur and the surrounding ground is not adversely affected when existing piles are extracted.
CONSTITUTION: Excavation bits 7 are made to extrude into the uppermost end of a main part 2 or of a front part 3 fitted to a front end of a main part 2 of a steel pipe and slide mechanisms 10, 11 and a holder connected in a V form with a pair of rod holding levers 12, 13 are interlocked and contained on the internal circumference. An extractor 1 made up like this is caused to stand as if it surrounded an existing pile, rotate, excavate the ground and be buried. After that, the holders 12, 13 are deformed by the slide mechanisms in order to hold the existing piles and then the extractor 1 is drawn up with the existing pile.
