Most municipal PVC drainage pipelines on the market are smooth straight pipes with inner and outer walls, and the corrugated pipe is not adopted because impurities remained at the trough position of the inner wall of the corrugated pipe which needs drainage for a long time to increase corrosion, and the smooth inner wall pipeline is beneficial to increasing drainage flow rate. For the common municipal PVC drainage straight pipe is mainly a single-layer PVC pipeline, the strength of the common municipal PVC drainage straight pipe is mainly determined by manufacturing materials, waterlogging occurs in a plurality of cities in summer in China in the present year, the drainage problem is particularly emphasized, when the drainage amount is large, huge water pressure can cause pipeline expansion to generate cracks, and then the problems of cracks and pipeline breakage, drainage leakage and influence on normal drainage occur. In order to improve the structural strength of municipal PVC drainage pipelines, I propose a novel municipal PVC drainage pipeline.
