Zusammenfassung:	The utility model provides an HDPE rectangular high-rib winding pipe. The corrugated pipe comprises a pipe body and bell and spigot joints at the two ends of the pipe body, the pipe body is formed bywinding a strip, the strip is integrally formed by a ribbed pipe and a bottom strip, the section of the ribbed pipe is rectangular, two rectangular PP corrugated pipe supports are arranged in the ribbed pipe, and PP, HDPE and PP three-layer composite vertical ribs are sequentially formed in the middle of the section of the rectangular ribbed pipe. The outer surface and the bottom belt of the rectangular ribbed tube are made of HDPE materials. The beneficial effects of the utility model are that; rib pipes and a bottom belt of the HDPE rectangular high-rib winding pipe are integrally formed ina melt extrusion mode. The HDPE vertical ribs and the two rectangular PP pipe walls in the rib pipe form three layers of composite vertical ribs, the sectional inertia moment of the rib pipe is maximized, meanwhile, the charac
