Abstract

PURPOSE: To enable the construction of a concrete pile with larger strength than a mortar pile by giving combined roles of a concrete-striking pipe and a tremie pipe to a rotary shaft in a foundation pile constructing method by using the cast-in-place concrete to large diameter.
CONSTITUTION: An excavator A is equipped with a digging bit 2 and a hole- expanding bit 3 which can be expanded at the bottom of a dug hole at the tip part of a rotary shaft 1 used for both a earth discharge pipe and a concrete-striking pipe. By emploing this excavator A, the hole is dug, while the excavated earth and sand being sucked and discharged by the rotary shaft 1. When the digging reaches a give depth, the hole-expanding bit 3 is expanded to broaden the bottom. When the expansion being ended, the discharge of earth is discontinued immediately, and the concrete is cast through the rotary shaft 1 to build a bulb at the bottom expanded. Then, the rotary shaft being pulled up gradually, the concrete 4 is cast. In the middle of this process of working, the hole is expanded by expanding the bit 3 and the concrete is cast to form a knot 5.
