Technical Field

The invention relates to the technical field of drainage engineering, in particular to a plastic pipeline with a self-cleaning structure for sewage drainage for a municipal sewer.

Background

The sewer is a public facility in cities, the device appears as early as the ancient Roman period, generally speaking, a sewer system is used for collecting and discharging domestic wastewater generated in cities and industrial wastewater generated in industrial production, at present, the sewer is of a round pipe type, plastic pipes are widely applied to gas pipes, water supply pipes, oil delivery pipes and the like due to the characteristics of good corrosion resistance, no leakage, excellent flexibility, good scratch resistance, rapid crack transmission and bending resistance, long service life and the like, the trend of the development of the domestic and foreign plastic industries is wide popularization and application, the interior of the plastic water pipe is smooth, a thin mud layer can be formed on the inner wall of the water pipe due to the fact that tap water cannot be discharged, a large amount of bacteria can be bred when the tap water pipe is not used frequently at night, the tap water used in the next morning has great potential safety hazard.

Through the retrieval, chinese patent application number is CN 201621024912.3's patent, discloses a steady state pipe with self-cleaning function, and the steady state pipe is five layer structures, by outer to interior outer, glue glutinous layer, intermediate level, interior glutinous layer and the inlayer of gluing outward in proper order, the skin is tripropylene polyethylene or polyethylene plastics, the intermediate level is the aluminium strip, the skin links to each other through gluing glutinous layer outward with the intermediate level, the inlayer is super-hydrophobic material, the inlayer links to each other through gluing glutinous layer in passing through with the intermediate level. The steady-state tube with self-cleaning function in the above patent has the following disadvantages: the flow velocity of liquid in the pipeline is faster, especially causes great impact to the pipeline of vertical transport, reduces the life of pipeline.
