摘要： 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.

摘要： PURPOSE:To make anchorage of solid reinforcing material feasible by a method wherein a form is arranged on a threshold of an excavated groove, a blind cover is provided to an opening on the outside of the groove, the inside of the form is filled with filling agent, and a protection wall is formed to the surface of a natural ground except the place of the form. CONSTITUTION:An excavated groove 2 is formed and, at the same time, a belt-like reinforcing material 1 is inserted therein. A form 3 is placed on a threshold of the excavated groove 2, and a blind cover 6 is attached to the form 3. A grout hose 8 is inserted through an insert hole 10 provided to the blind cover 6, and filling agent such as grout is injected through the hose 8. Then a space around the belt-like reinforcing material 1 in the excavated groove 2 is filled therewith, and filling to the inside of the form 3 follows. After the filling is finished, the grout hose 8 is removed from the insert hole 10, and mortar 15 is sprayed to the natural ground surface Ms to construct a protection wall for the natural ground M. On spraying the mortar, the thickness of spraying is determined by using the outer edge of the form 3 as a ruler.
