AI Technical Summary
Existing drainage pipes are prone to rapid wear due to friction and impact when the water flow velocity is high or when they carry solid particles such as sand and mud, resulting in a reduction in pipe wall thickness.
An anti-erosion drainage pipe with protective components was designed. By setting up protective pipes, guide rings, limit frames and locking grooves, a buffer layer is formed to isolate water flow from directly impacting the inner wall of the pipe and prevent wear.
It effectively extends the service life of the pipeline, reduces wear caused by water flow impact and friction, and improves the durability of the pipeline.
