  • Consolidation Of Soil By Introduction Of Solidifying Substances Into Soil (AREA)

Abstract

PURPOSE: To uniformly and strongly solidify soft ground by injecting plural grouts having different permeabilities in an overlapping manner into the ground to be grouted while changing injection stage by moving a multiple tube.
CONSTITUTION: A grout of bad permeability is injected from one discharge port of a grouting multiple tube into the ground in order to form a solidified seal having a packing effect in spaces between the multiple tube and the ground; that is, the injection of the grout of bad permeability results in the formation of a solidified region A where the areas 4, 4a, and 4b are centered because the grout can penetrate into larger voids alone. Then, a grout of better permeability is injected into the ground, whereupon the grout forms fissures 5 as new penetration source and then penetrates into between soil particles in the new penetration source. Thus, since slack portion is already filled with the grout of bad permeability in the injection stage, the grout of better permeability can solidify in a certain form, like a region B.
