LAYING METHOD FOR PIPE, ETC. TO SOFT GROUND, ETC.

摘要

PURPOSE:To improve execution-ability, etc. by constructing tilt continuous walls so as to mutually approach, forming a structure with a V-shaped section into the ground and laying the pipe, etc. into the structure. CONSTITUTION:A device proper 1 is inclined onto a catapillar holding machine 2 at a necessary angle, and the lower end of an agitating shaft 3 is set onto the surface of the earth. The agitating shaft 3 is dropped while being turned, a milky coagulant is injected into the ground from an injection hole 7 by rotating the agitating shaft 3, and the tilt continuous wall 14 is formed. Another tilt continuous wall 15 is shaped by conducting the same work from an opposite position, and the V-shaped structure 16 is constructed. Soil in the V-shaped structure 16 is removed, and the pipe 17, etc. are laid.
