Abstract

PURPOSE: To maintain the straight-driving property of the excavating shaft employed at the time of overlapping ground improvement, by fitting a cylindrical excavation drum to an excavating blade provided at the tip part of the excavating shaft.
CONSTITUTION: The cylindrical excavation guide drum 4 is fitted firmly on the outer periphery of the excavating blade 2 provided at the tip part of the excavating shaft 1. On the drum 4 a cutting edge 4a is formed. When the excavating shaft 1 fitted firmly with the excavating blade 2 and a stirring blade 3 is rotated and driven into the soil, the cutting edge 4a of the drum 4 makes and advances excavation, forming an excavation diameter in the soil. By this constitution, the center of the excavating shaft is prevented from becoming eccentric even when the ground improvement is conducted in a place which overlapps with the one in which the ground improvement is already finished.
