The utility model discloses a spatial and temporal distribution physical simulation device of initial stage rainwater polluting thing in soil can determine the initial stage rainwater in the infiltration circumstances of different rainfalls in the soil body, can study the accumulation of pollutant in the soil body through pedotheque and the surplus liquid sample gathered not in the co -altitude soil layer to probe the spatial and temporal distribution law of initial stage rainwater polluting thing in soil. The device bankets a cylinder section of thick bamboo, trompil metal mesh, stainless steel bearing support and the surplus liquid collecting vessel four bibliographic categories by the transparent and divides and form, can accomplish a series of experiment process such as initial rainwater simulation, rainwater infiltration, the high sample collection of each soil layer and surplus liquid recovery. This technique can provide an effective scheme for monitoring initial stage rainwaterpolluting thing distribution situation in the soil body, has important theory innovation value and engineering meaning, provides theory and technical guidance for the development in sponge city.
