Background
Municipal drainage pipes refer to rainwater and sewage pipelines under municipal roads, namely commonly called as 'sewer pipelines', rainwater is generally drained into rivers nearby, and sewage is drained into sewage treatment plants. The sundries washed by rainwater are more, plastic bags, paper scraps, leaves, silt and the like are mixed usually, the rainwater mixed with the sundries is discharged into the municipal drainage pipeline, the sundries are accumulated to reduce the water passing cross section of the municipal drainage pipeline, the drainage capacity of the municipal drainage pipeline is weakened, and road ponding and urban waterlogging are caused easily. Some municipal drainage pipe's sewer is provided with the filter screen, can filter most debris through the filter screen, but sets up the water cross-section that leads to that the filter screen can reduce the sewer on the one hand, and on the other hand filter screen can not filter silt yet. When rainwater enters the drain pipe with small gradient from the sewer with large gradient, the flow speed is reduced, silt and suspended solid carried in the rainwater are easily deposited in the drain pipe with small gradient, and therefore the drainage pipeline silts up. Silt of silting up in the drain pipe itself is difficult to clear up, and stifled drainage pipe is constantly silted up to silt, finally causes road ponding and urban waterlogging.
