METHOD PURIFICATION FOR POLLUTION OF SOIL IN-SITU

摘要

PURPOSE: A pollution purification method of contaminated soil is provided to purify the contaminated soil inside a constant area around a bore hole, and to prevent the ground density degradation around the bore hole. CONSTITUTION: A pollution purification method of contaminated soil comprises the following steps: punching a bore hole using a bore hole drilling apparatus(100); compressing a drug solution formed by dissolving drugs for purifying the contaminated soil to water, with a extra-high pressure pump(200); connecting the bore hole drilling apparatus with the extra-high pressure pump through a double swivel(140) on top of a double rod(120); inserting the double rod to the bore hole; cutting the ground by high-pressure spraying the drug solution using a jet nozzle and inserting the drug solution to gaps; and rotating the double rod to purify the soil.
