PILE CONSTRUCTION METHOD FOR REINFORCING SOFT GROUND

摘要

The present invention provides a method to construct a pile for reinforcing soft ground, capable of preventing environmental pollution, caused by grout, and easily constructing a pile. The method includes a step of forming an injection hole by boring the ground; a step of placing a double-wall tube, in which a lower part of a grout injection pipe is fixed, into the injection hole; a step of filling a gap between inner and outer walls of the double-wall tube with high pressure gas; and a step of filling the inside of the double-wall tube with the grout through the grout injection pipe.
