1、 Difference in material selection The plastic manhole for rainwater needs the function of dust and mud, because the rainwater will wash the sand on the ground into the manhole, and if there is no dust and mud pool, it is easy to block. Due to light pollution of rainwater, it can be directly discharged into urban rivers after being collected by rainwater plastic inspection wells. After natural sedimentation, it can be used as natural municipal water for landscape water and road sewage spraying
