PROBLEM TO BE SOLVED: To increase density by compressing peripheral earth and sand while forming lump bodies formed of an injection material itself in a ground by statically injecting it into the soft ground by pressure. SOLUTION: A liquid A and a liquid B are joined and mixed and the mixed liquid is injected into the ground by pressure, and a slump of the joined liquid is≥5 and a cure developing material ratio in the joined liquid is <50 weight percent. The liquid A is a suspension which has as an effective component a silica-based noncurable powdery body (material F), a calcium-based powdery cure developing material (material C), and water (material W) or a plastic gel. The liquid B has as an effective component a gelling adjusting material. The cure developing material ratio=C/(F+C)×100(%), and both F and C indicate weight. COPYRIGHT: (C)2007,JPO&INPIT
