The spring-type reinforcement lining is made of steel wire with plastic coating or high-strength plastic wire on its surface; the random-wire pipe wall is made of plastic wire extruded by an extruder and disrupted during molding, with a void ratio of 70-95%, and a diameter of 0.3mm to 3mm; the spring-type reinforcement lining and the random-wire pipe wall are closely contacted by the tension of the spring; the spinneret filter is made of synthetic fiber wire sprayed on the surface of the random-wire pipe wall. However, the drainage pipe of this structure is soft in texture, has a relatively general longitudinal compressive performance, is easily squeezed and deformed, and thus affects the drainage performance. In addition, the contact area between this type of pipe and the land is small, and the liquid interaction performance with the land is relatively general, so it cannot complete the drainage task well.
