[0002] At present, in the HDPE hollow wall winding pipe industry, its main structure is a rectangular structure assisted by melt adhesive bonding, which has high strength and is easy to install. However, in the actual process, the ring stiffness of the pipe will fluctuate greatly due to the selection of different formulas and the volatility of the structure. And in the actual handling and transportation process, the rectangular single-cavity structure is prone to collapse or damage when it is subjected to external force in the middle. This is mainly because most companies expand the length-to-width ratio of the rectangle to reduce the meter weight in order to pursue low weight of the product. When the large length-to-width ratio is subjected to external force, the middle part is deformed and damaged due to lack of effective support. Summary of the invention
