Title:
CONTAMINATED SOIL TREATMENT CONSTRUCTION METHOD
Document Type and Number:
Japanese Patent JP2016017940
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a contaminated soil treatment construction method for soil contaminated by radioactivity, the method enabling a construction cost to be suppressed and a construction period to be shortened by effectively using the contaminated soil.SOLUTION: The contaminated soil treatment method comprises: a first step of excavating a ground surface in a range of a predetermined area to a predetermined depth, taking out and storing a non-contaminated sound soil 3; a second step of placing concrete layers 9, 10 on a bottom surface and an inner periphery of an excavated hole formed by the excavation in the first step; a third step of dumping an excavated contamination soil 5A, which has been stored, and a contaminated soil 20 into the excavated hole of a concrete layer form such that the excavated hole is filled with the soil and compacting the soil from above to harden the soil, the contaminated soil 20 being collected by exfoliating surface soil of mountains, fields, and the like; and a fourth step of piling the prestored sound soil 3 so as to cover the compacted contaminated soil from above.SELECTED DRAWING: Figure 8
