Method of inhibiting contamination of soil
专利汇可以提供Method of inhibiting contamination of soil专利检索，专利查询，专利分析的服务。并且PURPOSE: To prevent the movement or diffusion of noxious substance through soil, by forcibly pouring water into flooding pipes provided in he earth at the position where the noxious substance is existent and its vicinity, and collecting the noxious substance together with water through a suction pipe or the like provided on the ground or in a ditch, a pool or the earth.
CONSTITUTION: To the central part 8 of a region, 1,000kg 20%-salt water was spread. It was poured through flooding pipes 4 and sucked through a suction pipe 7. At the time of 10hr after the salt water was spread, 10m
3 water was spread to the vicinity of the part 8. The amount of salt in water having flowed into the suction pipe 7 in the lapse of 72hr after the salt water was spread was measured and integrated. The result was 178.3kg which meant the removal of the spread salt water at a ratio of 89% from the region. In order to efficiently attain the purpose of this method, a means for detecting noxious substance may be pref. provided between a structure and the flooding pipes, so that the pressure of water in the flooding pipes is held ordinarily at a natural value while it is raised by a pump or the like when noxious substance is detected by the detector means.
