SOLIDIFICATION TREATMENT METHOD FOR CONTAMINATED SOIL

摘要

PROBLEM TO BE SOLVED: To provide a solidification treatment method for contaminated soil capable of preventing diffusion of contaminants without a lot of cost as is conventionally required in more safety manner. SOLUTION: A cylindrical casing 10 which upper end side is closed and the lower end side is open is pressed into a ground of the land or a bottom of the water containing contaminated soil by applying static load and while an agitating blade 13 is inserted into the ground in the casing 10 and the agitating blade 13 is moved upward and downward under rotation, solidification material is added and mixed into the ground in the casing 10 and then the casing 10 is withdrawn.
