Abstract

PURPOSE: To reduce the cost of construction by a method in which a blowing agent is injected while mixing soil with a hardener into a place by a pump and a quick setting agent is also charged immediately before placement for in-situ back-filling work.
CONSTITUTION: Excavated soil is mixed with a hardener such as specific cement, and a blowing agent is injected into the mixture to form an expanded slurry. The slurry so formed is sent under a pressure to a back-filling place by pump, where the unit volume weight of the back-filling material 6 is made smaller than that of soil by adjusting the mixing ratio of excavated soil and hardener and the injecting amount of the blowing agent and also the unit volume weight of the soil is equalized with or made slightly greater than that of water. Since the unit volume weight of the material 6 is small when revetment is constructed, lateral soil pressure to the revetment wall 5 is small and the needs for enlarging the wall 5 is eliminated. The constructing cost can thus be reduced.
