Abstract

PURPOSE: To enhance the improving effect of the ground by preventing the accompanying rotating phenomenon of excavated soil by turning the upper and lower rotary blades of a stirrer to mutually opposite directions.
CONSTITUTION: The lower and upper rotary blades 6 and 8 of a stirrer 1 are turned mutually in opposite directions to excavate the ground by the bit 7 of the blade 6. An improving material is injected from a slurry injecting nozzle 4 into the ground, and the stirrer 10 is pulled up while agitating and mixing soil by preventing the adhesion of soil by the mutually reverse turning of the blades 6 and 8. The soil and the improving material are repeatedly mixed by the stirrer 10 to form a mixed and agitated layer. The occurrence of accompanying phenomenon of excavated soil can thus be prevented, and the uniform mixing of the improving material can be obtained. The improving effect of the ground can be enhanced.
