To provide a method for stabilizing a deep layer mixed soil which enhances the workability of highly cohesive soil such as fine sand, silts and clay, and a system therefor.
The method for stabilizing deep layer mixed soil includes drilling a hole in soil, injecting thereinto a soil dispersing agent containing at least one of (i) an acrylic acid polymer or copolymer or a salt thereof; (ii) an acrylic acid/sulfonic acid copolymer or a salt thereof; (iii) an acrylic acid/phosphoric acid copolymer or a salt thereof; (iv) a mixture of at least one of a sulfonic acid polymer and a phosphoric acid polymer with an acrylic polymer or a salt thereof, mixing the soil with the soil dispersing agent to form a mixture of the soil and the dispersing agent, and mixing the mixture of the soil and the dispersing agent with a cement binder to mainly form a soil-containing stabilized soil.
