FOUNDATION IMPROVEMENT MATERIAL AND FOUNDATION IMPROVEMENT METHOD THEREFOR
PROBLEM TO BE SOLVED: To prevent a liquefaction phenomenon during earthquake, and prevent ocean pollution due to flowing of radioactive substances included in underground water from Fukushima Daiichi Nuclear Power Station and the like to the ocean.SOLUTION: A plaster slurry which is generated as a by-product of an exhaust gas desulfurizer in a ground layer, and a sodium silicate solution being water glass are mixed for chemical reaction, then the mixture is pressed in the underground and solidified, clog of sand and the ground layer are solidified and shielded for preventing liquefaction phenomenon during earthquake, and entry of the underground water of Fukushima Daiichi Nuclear Power Station and the like into a building of the nuclear power station can be prevented.
【課題】 地震時における液状化現象を防止し、福島第一原子力発電所等から発生した地下水に含まれる放射性物質の海洋流出による海洋汚染を防止する。【解決手段】 地層に排煙脱硫装置の副製品として発生した石膏スラリーと水ガラスであるケイ酸ナトリウム水溶液を混合して化学反応させ地中に圧入し固化させ、土砂の目詰まりや地層を固化しシールドすることによって、地震時の液状化現象を防止するとともに福島第一原子力発電所等の地下水が原子力発電所の建屋内に侵入することを防止する。
