| description | PROBLEM TO BE SOLVED: To provide a construction method for a winged pile capable of constructing a winged pile of a large diameter with small torque and allowing a bearing layer to exhibit its intrinsic bearing force, while reducing moments produced on wings during use. SOLUTION: The construction method includes rotating the hollow pile 1 to bury it in the ground, the pile 1 being provided with drive wings 2 at or near its front end. At the start of burial of the pile 1 or during the burial, water or self-hardening fluid is ejected under high pressure from a nozzle 12 provided at or near the front end of the nozzle 11 inserted in the hollow part of the pile, to excavate and soften soil. The self-hardening fluid is injected into the bearing layer and mixed with the excavated soil, and the portion of the pile near the front end, including the wing 2, is installed within the mixture. |
