[0003] However, the ribbed part of the pipe is rectangular in shape. Since the pipe will be buried underground, in addition to the ground pressure, the pipe also needs to bear the pressure of the sewage inside the pipe and the suddenly increased pressure when a large amount of rainwater flows into the pipe during a rainstorm. The angular parts of the ribbed pipe are subjected to greater stress and are prone to deformation, wear, or even fracture. Therefore, it does not meet the existing requirements. For this reason, we propose a multi-layer multi-rib double-plastic reinforced composite winding structure wall pipe. Content of the Utility Model
