DEEP MIXING METHOD OF SOIL STABILIZATION FOR FLIMSY GROUND STIFFENING

摘要

The present invention is soft ground depth mixing treatment method for soft ground reinforcement one to weak reinforcing the bearing capacity of the ground to form a soft ground, soil and cement mortar and fire by the support mixture by injecting a mixture juipjae in structure punctures group a large diameter boring relate to.; Depth mixing treatment method for soft ground reinforcement according to the invention are ground drilling method comprising using an injection apparatus equipped with a large-diameter boring form a drilling depth by digging up the improved predetermined depth from the ground surface; Juipjae injection step of the drilling pulled out by raising the injection device through the injection juipjae injection and at the same time implantation apparatus of a large diameter boring machine as; Soon as the spray injection juipjae to the puncturing portion is formed at the same time curing structure to be formed a predetermined phase structure; It characterized by a made of an solidified layer forming step of forming a solidified layer by laying a mixture of juipjae on the structure.
