Perforated corrugated pipe is a new type of seepage and drainage plastic pipe with a corrugated appearance formed by adding other additives to high-density polyethylene (HDPE). Permeable corrugated pipe is processed by punching holes at the grooves and wrapping needle-punched geotextile around the outside of the pipe. According to the type of corrugated pipe, it can be divided into single-wall permeable corrugated pipe and double-wall permeable corrugated pipe. Since the pipe holes of this product are in the troughs and are strip-shaped, it effectively overcomes the disadvantage that flat round hole products are easily blocked and affect the drainage effect. According to different drainage requirements, the size of the pipe holes can be 10mm×1mm-30mm×3mm, and can be evenly distributed in ranges such as 360 degrees, 270 degrees, 180 degrees, 90 degrees, etc. It is widely used in drainage fields such as highways, railway subgrades, subway engineering, waste landfills, tunnels, green belts, sports fields, and slope protection caused by high water content, as well as agricultural and horticultural underground irrigation and drainage systems. Together with flexible permeable pipes and plastic blind ditches, it has become the three main products in China's civil engineering construction (seepage and drainage).
