Rainwater opening device with flow diversion and interception function

Abstract

The invention relates to a rainwater opening device with a flow diversion and interception function. The device comprises a well chamber with an upper opening and a through grip-shaped well cover covering the upper opening of the well chamber, and the interior of the well chamber is separated into a water passing chamber, a flow diversion chamber, a flow interception chamber and a drainage chamberthrough upper baffles, lower baffles and clapboards, wherein the upper baffles and the lower baffles are transversely arranged at intervals, and the clapboards are vertically arranged at intervals; the water passing chamber, the flow diversion chamber and the flow interception chamber are sequentially arranged from top to bottom and sequentially communicated with one another, the drainage chamberis located at the same side of the flow diversion chamber and the flow interception chamber and communicated with the flow diversion chamber, and the flow interception chamber and the drainage chamber are both communicated with an external municipal rainwater pipeline through pipelines. By means of the rainwater opening device, classified collection of rainwater on the ground can be achieved, that is to say that classified collection is automatically conducted on the rainwater on the ground according to different cumulative rainfall values, so that targeted classification treatment is conveniently conducted on treatment facilities at the tail end of an urban rainwater pipeline system to fully achieve the engineering benefits of each treatment facility, and therefore the water quality of downstream receiving water is protected.

Description

technical field [0001] The invention relates to the technical field of municipal drainage supporting facilities, in particular to a gully device with the function of diverting and intercepting flows. Background technique [0002] When rainwater falls from the sky to the ground, it will carry a large amount of dust in the air and dissolve various polluting exhaust gases in the air. After falling to the ground, it will take away the suspended solids and slag on the ground when it flows into the municipal rainwater collection facilities. Soil, so road rainwater generally contains more pollutants. For the same rainfall process, the cumulative rainfall increases continuously with the duration of the rainfall. At the same time, due to the continuous scouring and carrying effect of rainfall, pollutants in the air and on the ground will gradually decrease with the increase of cumulative rainfall. Therefore, different cumulative rainfall The content of pollutants in rainwater is als...

AI Technical Summary

Problems solved by technology

The traditional gullies collect and discharge all the rainwater coming from the road instead of diverting and intercepting the rainwater according to different accumulated rainfall, which prevents the downstream rainwater treatment facilities from being able to target different levels of pollution. Classified treatment of road rainwater will affect its treatment efficiency and effect and lead to pollution of downstream receiving water bodies
