Abstract

PURPOSE: To enhance water stopping property with an effective improvement of soft subsoil by feeding an injection material into a soft subsoil through a plurality of injection holes made in the subsoil after bars or tubular cores of steel material or the like are inserted thereinto.
CONSTITUTION: In consruting a tunnel D or the like, earth injection holes C's the diameter thereof is about several centimeters while their lengths are between several to several tens cms are bored with appropriate intervals into the ground B designed to be improved, and core materials 1 of bar or tubular type made of plastic materials or iron are inserted thereinto. Thereafter, an injection material is fed into the subsoil through the holes C to improve it. In this method, combined with the insertion of the bars or tubular material, the injection material solidifies the subsoil thereby effectively reinforcing the subsoil while improving the water stopping property.
