PURPOSE:To prevent flow-out of soil in a short time by controlling water content of quick ground with scattering soil-coagulant composed of mixture of CMC, calcium chloride and silica, etc., onto the surface of quick ground and stirring with digging. CONSTITUTION:(A) 10 pts.wt. CMC is mixed with (B) 10 pts.wt. calcium chloride, (C) 10 pts.wt. sodium metasilicate powder, (D) 0.3-5 pts.wt. silica and (E) 1-15 pts.wt. calcium carbonate to obtain a soil-coagulant. 360-1000g of said coagulant is decided as mixing amount per 1m<2> the surface of ground multiplied by 10cm depth and scattered onto the surface of quick ground to control water content to 30-45%, then stirred with digging in about 5-20cm depth, thus subjected to compaction with mixing suitable amount of cement, as necessary. |
