ABSTRACT:
A modified ground, which is utilized for an underground water cut-off wall, landslide protection wall, a foundation pile or the like, is formed in an earthen foundation with the use of an excavator having at least one rotary shaft. The rotary shaft includes a bit provided on a bottom end thereof, and at least one pair of upper and lower nozzles for jetting a consolidating fluid. The upper nozzle is capable of jetting the consolidating fluid in a downwardly diagonal direction so as to generate a joined jet of the consolidating fluid in a downwardly diagonal direction by collision of the consolidating fluid jetted from the upper and lower nozzles. In the present method, the rotary shaft is inserted into the earthen foundation to form a hole therein, and then withdrawn away from the hole while rotating the rotary shaft and jetting the consolidating fluid from the upper and lower nozzles against soil surrounding the hole for enlarging the diameter of the hole in such a manner as to perform an in-situ mixing and stirring of the consolidating fluid and soil. After the resulting mixture is hardened, the modified ground having a larger diameter than the hole is formed in the earthen foundation.
