a municipal drainage system

Abstract

The invention discloses a municipal drainage system. The system comprises a sewer cover plate, a filter assembly, a flow guiding device, a sedimentation tank and a sewer. The sedimentation tank is arranged below the flow guiding device, and one side of the sedimentation tank is connected to the sewer. The bottom surface of the sedimentation tank is lower than that of the sewer. The sedimentation tank is provided with a scraping device, and the bottom of the sedimentation tank is provided with a slope surface. The drainage system can effectively filter out leaves and the like in rainwater to prevent the sewer from being blocked and affecting the drainage efficiency. The particles such as sand and gravel are filtered out and precipitated to prevent the excessive sand and gravel from directlyentering the sewer and reducing the through water cross section of the sewer. The problem of sewer blockage is effectively solved, and sediment precipitating at the bottom can be effectively removedto prevent long-term accumulation of the sediment at the bottom of the drainage system from affecting the drainage system.

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] After the heavy rain, the road surface often accumulates water. At this time, the drainage system is needed to drain the road surface to prevent the excessive water on the road from affecting pedestrians and driving. The water washed down by the rain is often mixed with many sundries, such as some leaves or on the ground. These impurities will flow into the sewer along with the rainwater and block the sewer; the sediment in the rainwater will accumulate in the sewer for a long time, so that the water passage section of the sewer will be reduced, and the drainage capacity will become poor. Sediment is better treated. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a municipal drainage syst...
