CONSTRUCTION METHOD FOR TAKING POLLUTION DIFFUSION PREVENTION MEASURE AGAINST POLLUTION DIFFUSION SOURCE

摘要

PROBLEM TO BE SOLVED: To provide a construction method for taking pollution diffusion prevention measures by pretreating a pollution diffusion source with a flocculant, when a water area is subjected to dredging, soil disposal and soil improvement.;SOLUTION: In a construction method for taking pollution diffusion prevention measures, when a water area is subjected to dredging, soil disposal and soil improvement, treatment is performed by directly pre-immersing a pollution diffusion source such as dredged soil or sediment for use in the soil disposal in a flocculant or directly pre-spraying the flocculant on the pollution diffusion source; and the dredging or the soil disposal is performed within the water area by the treated dredged soil, the sediment for use in the soil disposal, or the like.;COPYRIGHT: (C)2014,JPO&INPIT
