GROUND IMPROVING METHOD FOR CONFINING HEAVY METAL- CONTAMINATED SOIL IN PRESENT POSITION

机译:当前位置限制重金属污染土壤的地面改良方法

摘要

PROBLEM TO BE SOLVED: To efficiently confine heavy metals in the present position for preventing the contamination of soil by the heavy metals and the like from diffusing, thereby coping with many contamination conditions.;SOLUTION: An impervious wall formed by agitating and mixing a cement- based solidifying agent and soil is constructed around ground contaminated with heavy metals such as zinc, mercury, lead, arsenic, and hexavalent chromium by a deep mixing method, and, if necessary, an impervious board is constructed in a layer under the contaminated ground, and at the same time, contaminated soil and the cement-based solidifying agent are agitated and mixed, thereby the contaminated soil is confined in the present position.;COPYRIGHT: (C)2002,JPO
