Abstract

PURPOSE: To form solidified soil lamps of high strength by a method in which an excavating liquid is injected on the way of injection of a grout for stabilizing the ground by using an injecting tube having independent flowpasses and the grout is again injected.
CONSTITUTION: An injection tube 1 having independent flowpasses 2a-2d and also having check valves 4a-4d on inlets to a grout mixing chamber 3 is provided. A ground-stabilizing grout is injected through the tube 1 into the ground region to be stabilized, and on the way of the grout injection, an excavating liquid instead of the grout is injected with high pressure through the flowpasses in order to excavate the ground hardened by the grout and also to mix soil in the ground. The ground-stabilizing grout is further injected through the original flowpasses to form high-strength solidified soil lumps.
