Municipal drainage pipeline

The invention discloses a municipal drainage pipeline. The problem that sludge in a current drainage pipeline can not be well treated and thus the pipeline is blocked by the sludge. According to the technical scheme, a blocking plate achieves communication between a rainwater chamber and a sludge chamber under the action of a drive device; a screw conveyor is arranged in the sludge chamber, a one-way valve is arranged at the connection portion of the sludge chamber and a sludge pipe, the one-way valve is provided with a vertically arranged valve plate, a high-pressure medium access hole is formed in the portion, near the one-way valve, in the sludge pipe, when a high-pressure medium enters the sludge pipe, the valve plate is closed, the sludge is transported to a sludge storage tank through the high-pressure medium, real-time filtering of rainwater and sewage flowing in a sewer line is achieved, sludge can be smoothly discharged to the pipeline, and blocking of the pipeline is avoided. 本发明公开了种市政排水管道，解决了目前的排水管
