At present, polyethylene pipes become plastic pipelines with second largest consumption in the world after PVC, and are widely used in engineering such as water supply, agricultural irrigation, gas transportation, pollution discharge, mine mortar transportation and the like, and fields such as oil fields, chemical industry, post and telecommunications. Plastic pipes with reinforcing ribs are increasingly used in many fields such as urban sewer pipes and drainage engineering. The inside of the water drainage pipe has no pressure, and different forms of reinforcing ribs are arranged on the periphery of the pipe wall in order to improve the performance of resisting external pressure and impact. The commonly used plastic pipe with reinforcing ribs mainly has two forms: one is made by adopting a direct extrusion molding mode, and the most representative is a double-wall corrugated pipe; the other is made in a spiral winding forming mode, and represents double-wall pipes, polyethylene winding structure wall pipes, steel strip spiral winding corrugated pipes and the like. The polyethylene winding structure wall pipe has very wide application, has the main advantage of being capable of manufacturing the pipe with the caliber larger than 1000mm by using small-sized equipment in the aspect of the caliber. However, the raw material used by the polyethylene winding structure wall pipe is mainly polyethylene, and the elastic modulus of the polyethylene is small, so that the ring stiffness of the manufactured pipe cannot meet the requirement, and the application and development space of the polyethylene winding structure wall pipe is limited.
In order to increase the ring stiffness of the winding pipe, at present, steel belts, steel ribs and other reinforcing structures are additionally arranged on the outer surface of the winding pipe, although the ring stiffness of the pipe is increased, the product structure is unstable due to structural reasons, stress points are too concentrated, the structure is extremely easy to damage, the steel belts, the steel ribs and the outer surface of plastic are combined too much, the stripping force of a combined part is low, and engineering accidents caused by the fact that the structure is damaged and a steel-plastic combined surface is stripped exist.
It is therefore of particular importance to design a pipe with high strength.
