摘要

PROBLEM TO BE SOLVED: To form a soil improvement body over a wide range in a lateral direction by chemical grouting in one place while keeping a chemical grouting amount small.SOLUTION: A main chemical solution EA reacting with water to gelate is penetration-injected in a laterally-prevailing manner into object ground 12 by injection pressure that does not cause cleavage of the object ground 12. Thus, a soil improvement body 50 assuming a flat shape longer in a lateral direction than in a vertical direction is formed in the object ground 12.SELECTED DRAWING: Figure 2
