Document Type and Number:
WIPO Patent Application WO/2023/019729
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of municipal road rainwater facilities. Specifically disclosed is a modular anti-sedimentation sewage-intercepting storm drain, comprising a rainwater grate, a prefabricated well, a primary screening basket, a diversion basket, a floating door, a sewage-intercepting basket and a sewage-intercepting frame. The primary screening basket is arranged below the rainwater grate, the diversion basket is arranged below the primary screening basket, the sewage-intercepting basket is arranged below the diversion basket, and the sewage-intercepting frame is arranged below the rainwater grate. A layering plate divides the sewage-intercepting frame into an upper sewage-intercepting frame and a lower sewage-intercepting frame. The primary screening basket, the diversion basket and the sewage-intercepting basket are all arranged in the upper sewage-intercepting frame. The floating door is arranged in the center of the sewage-intercepting basket, and may move up and down. The present invention is suitable for the reconstruction and new construction of storm drains. The use of the present invention may reduce the level of pollutants entering a rainwater main pipe while reducing the sedimentation of pollutants in rainwater runoff in a storm drain and in a connecting pipe from the storm drain to the rainwater main pipe under moderate and light rainfall, so as to ensure the overflow capacity of the storm drain under heavy rainfall and mitigate blockages.
