Abstract

PURPOSE:To determine the improving degree of ground only by the amount of improving agent to be injected by a method in which a mixer having an excavating screw on the tip of its hollow shaft and a stirring blade and an injection port on its periphery is rotationally penetrated to a given depth into the ground, and a soil improving agent is injected there. CONSTITUTION:An excavating screw 1 is provided to the tip of a hollow shaft 4, a stirring blade 3 is provided to the other periphery, and plural injection ports 2 are provided in the longitudinal axial direction of the hollow shaft 4 to make up a mixer. The mixer is turned in soil for excavation to a given depth. A soil hardening slurry is then injected from the hollow shaft 4 while pulling up the shaft 4 slowing as needed. The mixing ratio of soil and hardening slurry can thus be determined only by the amount of the slurry to inject.
