Background

The hollow winding pipe is a pipe which takes high-density polyethylene (HDPE) as a raw material and is formed by winding and welding, and the special forming process can be used for producing the pipe with the diameter of 3 meters, which is difficult to complete by other production processes, and the high-density polyethylene (HDPE) not only ensures the product forming process and the product quality due to the excellent fusion welding performance, but also provides a plurality of reliable modes for construction connection, such as electric fusion welding, thermal contraction connection and the like, and is an important reason for rarely occurring leakage, and only has the special environmental protection function which other pipes do not have, so that the pollution prevention and treatment of people currently concerned provides a very effective method.

When the existing winding pipe is used as a buried drain pipe and a drain pipe, the pressure on the ground needs to be born, but the structural strength of the existing winding pipe is low, so that the compression resistance of the existing winding pipe is generally high, the larger ground pressure is difficult to bear, and currently, in order to solve the problem, a steel belt is usually arranged on the winding pipe to improve the compression resistance of the winding pipe, for example, chinese patent CN215891440U discloses a novel steel-plastic reinforced winding pipe, and although the compression resistance of the winding pipe is effectively improved by arranging steel sheets, the weight of the winding pipe is greatly increased in actual use, so that the winding pipe is inconvenient to transport, and the transportation cost is also improved.
