Abstract

PURPOSE: To provide a large bearing force for a pile by detachably providing a circular steel plate having a soil discharge port on its periphery, an axle steel pipe on its center, an excavating blade with a claw and a tip expansion shoe on its lower part to the lower face of a casing.
CONSTITUTION: A circular steel plate 1 is detachably attached to the lower face of a casing C, a central axle steel pipe 2 having a hole 7 for an injection pipe D is provided at the center of the circular steel plate 1, plural conical excavating blades are provided on the periphery of the central axle steel pipe 2, and a fish tail is provided at the lower end of the excavating blades 3. Also, a large number of soil discharge ports 6 are drilled in the periphery of the circular steel plate 1. Excavation is made by the excavating blade 3, and soil and sand pushed up by the periphery of the circular steel plate 1 are discharged by the casing C. Thus, a great bearing strength can be provided to the high strength pile without imposing any fatigue on the buried pile (not illustrated).
