Municipal road initial rainwater collection device based on rainwater and sewage diversion

Abstract

The invention relates to a municipal road initial rainwater collection device based on rainwater and sewage diversion. The municipal road initial rainwater collection device comprises a rainwater pipeline and a sewage pipeline which are buried underground in parallel, a plurality of rainwater inspection wells are arranged on the rainwater pipeline, a first connecting pipe is arranged between every two adjacent rainwater inspection wells in a communicating mode, a plurality of sewage inspection wells are arranged on the sewage pipeline, and a second connecting pipe is arranged between every two adjacent sewage inspection wells in a communicating mode. Rainwater and sewage connecting pipes are arranged at the bottoms of the rainwater inspection wells in a communicating mode, and the ends, away from the rainwater inspection wells, of the rainwater and sewage connecting pipes communicate with the sewage inspection wells. The municipal road initial rainwater collection device based on the rainwater and sewage diversion has the effect that the possibility that rainwater circulation is not smooth due to the fact that a slag blocking cage is not cleaned for a long time is reduced, and the possibility that water is polluted and the environment is influenced due to rotting and stinking of impurities blocked on the slag blocking cage for a long time is reduced.

Description

technical field [0001] The present application relates to the field of rainwater collection, in particular to an initial rainwater collection device for municipal roads based on rain and sewage diversion. Background technique [0002] The initial rainwater often dissolves polluting gases such as acid gases in the air, factory exhaust gas, and car tails. When it falls to the ground, it will wash away the roof and asphalt concrete roads, etc., making the initial rainwater contain many organic pollutants and heavy metals. Direct discharge into the river will cause a certain degree of pollution to the water environment treatment, so it is necessary to collect the initial rainwater. [0003] The Chinese patent with the authorized announcement number CN208039405U discloses an initial rainwater collection device for municipal roads based on rain and sewage diversion, including rainwater pipes and sewage pipes. The rainwater pipes are provided with multiple rainwater inspection well...

AI Technical Summary

Problems solved by technology

[0004] Regarding the related technologies mentioned above, the inventor believes that the rainwater collection device can separate the initial rainwater from the drainage system. Located at the bottom of the well, the staff needs to go down the well to clean it every time, which brings great inconvenience to the staff. If the slag cage is not cleaned for a long time, it will cause the clogging of the slag cage, which will affect the rainwater collection effect of the rainwater collection device, and the slag trap The impurities on the cage will also rot and smell, polluting the water body
