Zusammenfassung:The utility model discloses a wall pipe material with a high-density polyethylene-wound structure. The pipe material has the structure that a polyethylene pipe wall is externally and spirally wound with at least one layer of hollow rib pipes, layers of the rib pipes are arranged with one another at intervals, the outer-layer rib pipe and the inner-layer rib pipe are tangent with each other in a goods font-shaped way, and the tangent rib pipes are fixed with one another in a welding way. After the wall pipe material is used, the raw material can be saved, and the finished product cost can be reduced. Compared with the prior art, under the same pipe diameter and the same pipe weight, the wall pipe material is greatly higher in ring stiffness, and high in use reliability, thereby being widely applicable to the fields such as the rainwater and waste water drainage engineering, the drainage in the chemical industry and the like.
