Abstract
PURPOSE: To improve a poor subsoil efficiently by forming a primary hardening pile when a jetting agitator is lowered into a poor subsoil and then, the secondary hardening pile when it is lifted.
CONSTITUTION: A hollow rod 1 is positioned above a poor subsoil equipped with a jetting agitator 2 at the lower end thereof. Then, the jetting agitator is rotated by jetting water or the like at the tip thereof and mixes a poor subsoil with agitation with a soil stabilizing material being injected through injection holes 5 and 5 at the tip of a high pressure injection arms 4 and 4 so that a pile with an expanded diameter is formed sequentially as it is lowering down to a given depth so as to make a primary hardening pile. Then, it is lifted rotating to pull out. At the same time, a soil stabilizing material is injected under a low pressure into a hollow part of the primary hardening pile whereby the secondary hardening pile is formed for improved subsoil with a larger diameter.
