METHOD FOR CONSTRUCTING STEEL PIPE REINFORCED SOIL CEMENT PILE

摘要

PROBLEM TO BE SOLVED: To avoid discharge of soil containing a hardener when a steel pipe reinforced soil cement pile comprised of a steel pipe and soil cement is constructed. SOLUTION: There is provided an excavating rod 1 which has at least an excavating/agitating blade 5 and an agitating blade 3 at its tip, has a lower exhaust port 7 and an upper exhaust port formed in a portion near the tip and a portion near the agitating blade 3, respectively, and includes a spiral screw 4 arranged above the agitating blade 3. During driving of the excavating rod 1, when the lower exhaust port 7 reaches a depth which is above a location where the upper exhaust port 8 reaches when the excavating rod 1 lowers to an undermost location, soil cement construction is started while a hardening solution is injected from the lower exhaust port 7.
