Embodiment Construction

[0027] During the use of the traditional rain-sewage pipe system inspection well cover, rainwater or sewage flows into the drainage pipe from the opening of the rain-sewage pipe system inspection manhole cover, and flows out in the drainage pipe. The smell of the water in the drainage pipe will come from the rain The water inlet of the manhole cover of the combined sewage pipeline system overflows, which in turn affects the environment, causes environmental pollution, and affects people's health.

[0028] In view of this, the designer of the present invention has designed a rain-sewage confluence pipeline system manhole cover and a rain-sewage confluence pipeline system, by improving the structure of the rain-sewage confluence pipeline system manhole cover, in the actual use process, sewage or rainwater from the rain Inflow from the port of the manhole cover of the combined sewage pipeline system, enter the drainage pipeline, and be discharged through the drainage pipeline. At ...

Abstract

The invention provides a rainwater and sewage mixing pipeline system and a manhole cover thereof, and belongs to the technical field of drainage. The manhole cover comprises a cover body and an anti-overflow component, wherein the cover body comprises a water inlet and a water outlet, and a flowing channel is formed between the water inlet and the water outlet; and the anti-overflow component is arranged in the flowing channel, enables smoothness from the water inlet to the water outlet, and enables blockage from the water outlet to the water inlet. After the manhole cover of a rainwater and sewage mixing pipeline system is arranged behind a drainage pipeline, bad smell generated by sewage cannot overflow from the manhole cover when the sewage flows in the drainage pipeline, the environment cannot be influenced, and the effect of environmental friendliness can be achieved.

Description

technical field [0001] The invention relates to the technical field of drainage, in particular to a manhole cover of a rain-sewage confluence pipeline system and a rain-sewage confluence pipeline system. Background technique [0002] The present invention aims at serious environmental protection problems in the inspection wells of rainwater and sewage shared pipelines. Because of the rainwater collection and discharge function of common rainwater and sewage shared drainage pipelines, the inspection well covers of the rainwater and sewage confluence pipeline system are all made into grid-shaped, grid-shaped rain pollution Although the manhole cover of the combined pipeline system can ensure the rapid collection and discharge of rainwater, in summer, the sewage emits an unpleasant stench and permeates the air directly through the manhole, which seriously affects the image of the city and the quality of life of citizens. Citizens complain constantly and urgently need to be resol...
