PURPOSE:To prepare light weight solidified soil, which requires no special mixer, resists even high pressure feed, has high fluidity under a non-solidified state, has excellent workability due to high fluidity and has a wide applicability. CONSTITUTION:Soil, a solidifying material and water-absorbed and expanded gel-like resin granule are mixed, the mixture is transferred and charged to the position of execution under a non-solidified state, and left at stand and solidified, and bubble-shaped air gaps are formed in soil by the drying and shrinkage of resin granule after solidification. The method can be applied to the filling of a cavity section in the periphery of a structure with land subsidence. When the structure is supported by pile foundations 12 in a poor subsoil 10, the mixture is pressure-fed by a pump into the air gap generated between the ground and a footing 14 by the subsidence of the poor subsoil 10 to fill the air gap, and left at stand and light-weight solidified soil 16 is formed, thus filling the air gap section. The method can also be applied to other back-filling material, banking material, light-weight column, etc. |
