Geotechnical treatment method of landfill and industrial wastes landfill and soil solidification composition of the ground

摘要

When landfill of household garbage and various industrial wastes is landfilled in the ground of the landfill without any construction work, the leachate generated from the household garbage and industrial wastes will destroy the environment by burning the landfill trough and its ground water.;As a means to overcome such environmental destruction, the soil is solidified, and the soil composition is applied to the first, second and third layers of the landfill in this order to solidify and cure.;The solidification curing thickness of the filler is preferably 0.6-1.0 m.;The third layer is constructed with a 5% slope, and at the same time, a plurality of leachate inflow passages having a semicircular cross section are disposed on the third layer, so that a semicircular groove formed by flooding is formed.;The soil solidifying composition used is 25 wt% zeolite, 60 wt% local soil, 2-5 wt% coconut oil treated lime, 10-15 wt% cement, 1-2 wt% transparent waterproofing solution, 1-2 wt% % Of calcium chloride, 0.03-0.20wt% of calcium chloride, 0.03-0.20wt% of magnesium chloride, 0.03-0.20wt% of sodium chloride, 0.0002-50wt% of sodium chloride, 0.01% by weight of silicate, 0.001-0.01% by weight of silicate, and 0.001-0.02% by weight of sodium sulfate.;The first layer obtained by this construction method had a coefficient of permeability of 10^-7Cm / sec, a compressive strength of 15 kg / cm 2 and a second layer having a coefficient of permeability of 10^-7Cm / sec compressive strength of 10 kg / cm 2, and the third layer has a coefficient of permeability of 10^-10Cm / sec or more, and the leachate is completely waterproofed.
