GROUND INJECTION AGENT COMPOSITION FOR PREVENTING LIQUEFACTION, AND GROUND IMPROVEMENT CONSTRUCTION METHOD USING THE COMPOSITION
PROBLEM TO BE SOLVED: To provide a ground injection agent composition for preventing liquefaction, from which a gel product, that has an adequate gel time and is excellent in permeability to the ground, deformation resistance and durability, can be obtained and to provide a ground improvement construction method using the ground injection agent composition for preventing liquefaction.SOLUTION: The ground injection agent composition for preventing liquefaction contains (meth)acrylic acid metal salt (A), a polyvalent metal salt compound (B) other than the (meth)acrylic acid metal salt (A), an oxidant (C), a reductant (D) and water (E). The total amount of the (meth)acrylic acid metal salt (A) and the polyvalent metal salt compound (B) is 3-15 mass% of that of the ground injection agent composition. The reductant (D) contains at least one compound selected from thiosulfate compounds and bisulfite compounds. The ground improvement construction method is based on an infiltration solidification processing method using the ground injection agent composition for preventing liquefaction.SELECTED DRAWING: None
