CONTAMINATED SOIL TREATMENT CONSTRUCTION METHOD
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
【課題】汚染土を有効に活用して工事費用を抑制するとともに工事期間の短縮を可能とする放射能等に汚染された土地の汚染土壌処理工法を提供する。【解決手段】地表を所定面積の範囲で所定深さまで掘削して汚染されていない健全土壌３を取り出し保管する第１工程と、当該第１工程で掘削して形成された掘削穴の底面及び内周にコンクリート層９、１０を打設する第２工程と、保管しておいた掘削した汚染土５Ａ及び山，野等の表面土壌を剥離して採取した汚染土壌２０を上記コンクリート層状の掘削穴に満杯になるように投棄して、上から締め固めて硬化する第３工程と、この締め固められた汚染土壌を上から被うように上記あらかじめ保管しておいた健全土壌３を堆積する第４工程とを備えた。【選択図】図８
