SHIELDING LAYER AND METHOD OF MULTILAYER SOIL ADDITION RESTORING USING THE SAME

摘要

A polluted soil barrier layer is provided to reduce the concentration of pollutant about dilute and to prevent the suppression, the neutralization, and the second prevention of environmental contamination by an additive. A polluted soil barrier layer comprises a heavy metal rising barrier layer(21) for blocking the heavy metal and the hydrogen ion rising from the pollute soil(10) of the lower part the neutralization, a moisture rising barrier layer(22) which is formed with the material in which the air gap is large and lowers the capillary tube high, an earth and sand barrier layer(23) consisting of the ecologically friend material in order to be disassembled after inflow of earth and sand intercepting part for two or three years.
