PILE PRESS-IN CONSTRUCTION METHOD AND MEMBER FOR PUSHING UNDERGROUND OBSTACLE ASIDE

摘要

PROBLEM TO BE SOLVED: To enable press-in of a pile by efficiently pushing an underground obstacle aside without reference to the size or hardness of the underground obstacle such as a stone.;SOLUTION: A member 3 for pushing an underground obstacle aside, which has a polygonal pyramid-shaped part 4 provided at a leading end of a polygonal column-shaped part 5, is pushed into the underground obstacle while being rotated or swung, and a space for allowing entry of a pile 2 is formed by drawing the underground obstacle near a periphery by the polygonal pyramid-shaped part 4 at the leading end and the polygonal column-shaped part 5 continuing therefrom. Thus, the pipe 2 is pressed into the space.;COPYRIGHT: (C)2012,JPO&INPIT
