DECONTAMINATION METHOD OF CONTAMINATED SOIL
PROBLEM TO BE SOLVED: To provide a decontamination method of contaminated soil which can permeate agents into a whole contaminated area of low permeable ground, and can purify high concentration pollutant adsorbed in silt ground or clay ground certainly.SOLUTION: In a method decontaminating ground polluted with hazardous material, a step II forming underground kneading body by injecting agents and water for the contaminated ground and penetrating or pulling out to an appointed depth with a stirring apparatus is performed. Before or in the step II, a step I feeding sand in the contaminated ground is performed.SELECTED DRAWING: Figure 2
【課題】透水性の低い地盤の汚染区域全体に薬剤の浸透が十分行え、シルト地盤や粘土地盤に吸着した高濃度汚染物質を確実に浄化する汚染土壌の浄化方法を提供する。【解決手段】有害物質で汚染された地盤を浄化する方法であって、撹拌装置を使用し、該汚染地盤に対して薬剤と水を注入しながら撹拌混練し、所定の深度まで貫入又は引き抜くことで、地中混練体を形成するＩＩ工程を行う浄化方法であって、該ＩＩ工程前又は該ＩＩ工程において、砂類を該汚染地盤に供給するＩ工程を行う。【選択図】図２
