a municipal drainage system

Abstract

The invention discloses a novel municipal drainage system. The system comprises a sewage outlet cover plate, a filter assembly, a flow guiding device, a sedimentation tank and a sewer, wherein the sedimentation tank is arranged under the flow guiding device, one side of the sedimentation tank is connected with the sewer, the filter assembly is arranged under the sewage outlet cover plate, and thefilter assembly comprises screen cloth, sliding blocks arranged at the two ends of the screen cloth and a spring connecting the screen cloth and the sliding blocks. The novel municipal drainage systemhas the advantages that leaves and other items mingled in rainwater can be effectively filtered out to prevent the sewer from being blocked to affect the drainage efficiency; sand, stones and other particulate matters are filtered and precipitated to prevent excessive sand and stones from directly entering the sewer to make the water passing cross section of the sewer reduced, so that the problemof sewer blockage is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of urban drainage and waterlogging prevention engineering, and in particular relates to a municipal drainage system. Background technique [0002] With the acceleration of urbanization, the municipal drainage system is a very important livelihood project. After the heavy rain, the road surface often accumulates water. At this time, the drainage system is needed to drain the road surface. However, because there are many sundries washed down by the rainwater, usually mixed with some leaves, silt, etc., they enter the sewer together, making the drainage system unsmooth. The reduction will cause water on the road, complicate the road conditions, and affect the driving of vehicles; as debris accumulates in the pipeline, the water passage section of the sewer will decrease and the drainage capacity will deteriorate. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the p...

Problems solved by technology

After the heavy rain, the road surface often accumulates water. At this time, the drainage system is needed to drain the road surface. However, because there are many sundries washed down by the rainwater, usually mixed with some leaves, silt, etc., they enter the sewer together, making the drainage system unsmooth. Reduced, causing water on the road, complicating the road conditions and affecting the driving of vehicles; as debris accumulates in the pipeline, the water passage section of the sewer becomes smaller and the drainage capacity becomes poorer
