SOIL CONCRETING COMPOSITION AND CONSTRUCTION METHOD FOR TREATING SOFT GROUND OF RECLAIMED LAND FOR GARBAGE AND INDUSTRIAL WASTES BY USING THE COMPOSITION

摘要

PURPOSE: Provided are a soil concreting composition and a construction method for treating soft ground of a reclaimed land for garbage and industrial wastes by using the composition, which can prevent leachate from permeating into soil and groundwater of the reclaimed land. CONSTITUTION: The soil concreting composition comprises 2-5wt.% of unslaked MgO and gypsum powder, 80wt.% of field soil such as mountain or coastal soil, 2-5wt.% of unslaked lime, 10-15wt.% of cement, 1-2wt.% of clear waterproof liquid and urine, 1-2wt.% of water, and 1-2wt.% of a soil concreting mixture comprising 0.05-0.35wt.% of potassium chloride, 0.03-0.25wt.% of calcium chloride, 0.03-0.20wt.% of magnesium chloride, 0.03-0.20wt.% of sodium chloride, 0.0002-0.01wt.% of cobalt chloride, 0.0002-0.01wt.% of silica, 0.001-0.02wt.% of sodium sulfate. The construction method for treating the soft ground of the reclaimed land is performed by concreting a groundwater flowing layer(12) to have a thickness of 0.3-0.4m, a groundwater efflux freeze protection layer(13) to have a thickness of 0.2-0.3m, and a leachate shielding and waterproof surface layer(14) to have a thickness of 0.1-0.3m by using the soil concreting composition.
