Abstract

PURPOSE: To improve the accuracy of the improvement of the subsurface by a method wherein the injecting pressure of water or air can be adjusted which is used for obtaining impact action necessary for the improvement of the subsurface.
CONSTITUTION: An injecting pipe 1 provided with a whole circumference horizontal injecting head 2 is inserted into a sandy subsurface 3 by a fixed depth. Water or air is jetted into the sandy subsurface 3 in the horizontal direction through the whole circumference horizontal injecting head 2, and soil grains are moved and contracted. Fillers are injected into voids formed by the movement and contraction, and the subsurface is hardened.
