Description

Technical Field

[0001] The utility model relates to a manhole cover, in particular to a manhole cover with a rainwater outlet garbage filtering circulation system, belonging to the technical field of urban road drainage facilities. Background Art

[0002] Urban road drainage facilities include road surface drainage and roadside drainage. Common road surface drainage facilities are usually manhole drainage devices, which drain water into the sewer outlet through multiple drainage holes on the manhole cover and then discharge it from the underground drainage pipe. In order to facilitate drainage, common manhole covers usually have larger drainage outlets, which makes drainage convenient and not easy to clog.

[0003] However, the common sewer drainage devices have basically no effect on filtering garbage and debris. Due to the large drainage outlet, when rainwater flows into the sewer through the drainage outlet, fallen leaves, garbage, mud, etc. will also enter the sewer network with the water flow. These things that cannot rot or degrade quickly, as well as materials such as sand and gravel that are not filtered, can easily accumulate in the underground drainage pipes, reducing the flow rate and flow channel of the drainage pipes, and slowly causing blockage. Therefore, when it rains, there are often urban flooding and serious waterlogging on the roads. Even road facilities that are originally used for drainage have manhole covers that are washed away from the sewer outlets by water pressure due to poor drainage, resulting in a great safety hazard.
