The construction method of landfill and pile in soft soil using the potential hydraulic material improved

摘要

PURPOSE: A landfill formation method on the soft ground using latent hydraulic materials is provided to function as a drainage layer while improving the soft ground, to have effects as a bearing layer and a cut-off layer after completing the function of a drainage layer and to form a landfill stabled structurally and advanced environmentally. CONSTITUTION: A landfill formation method on the soft ground using latent hydraulic materials comprises the steps of drying, crushing and sieve-shaking latent hydraulic materials such as byproduct lime, blast furnace slag, steel furnace slag, ash, etc. to have an appointed grain size, dissolving in a solvent by weighing fatty acid, lignin sulfonic acid and sulfonate, oxy carbonic acid and carbonate, sugar or soluble salts of Zinc and hydraulicity-lag materials at 0.1-2.0 percent weight against hydraulic materials, mixing the latent hydraulic materials and the solution, then drying to have 5-percent water content and composing vertical and horizontal drainage materials for improving the soft ground of a landfill using the manufactured materials having the effect of lagging the formation of a film and hydraulicity to be used for the protection of a bearing pile and a cut-off layer and as a cut-off layer.
