Inner rib reinforced polyethylene pe spiral corrugated pipe

Abstract

The invention an inner-fin-reinforced polyethylene PE spiral corrugated pipe which comprises a pipe substrate made of PE and a reinforcement pipe spirally and closely wound outside the pipe substrate. A corrugated pipe is adopted as the reinforcement pipe, the cross section of the reinforcement pipe is in the shape of a minor arc arch, and the secant line of the arch faces to the outer wall of the pipe substrate to enable the winding surface of the reinforcement pipe and the pipe substrate to be a flat surface; the cross section comprises a left cavity and a right cavity which are separated through a structure cavity; binding materials are arranged between the winding surface and the pipe substrate and overflow to be filled in the structure cavity to form a reinforcing rib. According to the inner-fin-reinforced polyethylene PE spiral corrugated pipe, the cavities are formed in the two sides of the reinforcement pipe, the reinforcing rib is arranged in the middle of the reinforcement pipe, and therefore the overall specific gravity is reduced while the certain circular rigidity and circular flexibility of the overall pipe are achieved; in addition, due to the fact that the substrate, the reinforcement pipe and the reinforcing rib are all made of the same materials, the compatibility among different components is good and close connection is achieved after the overall pipe is finished. The inner-fin-reinforced polyethylene PE spiral corrugated pipe is applied to municipal pipelines.

Description

technical field [0001] The invention relates to a municipal pipe, in particular to a plastic sewage and drainage pipe. Background technique [0002] In municipal construction, the burial of underground drainage pipes and sewage pipes is an important municipal project. Commonly used drainage pipes and sewage pipes include concrete pipes and metal pipes. The new material high-strength polyethylene has strong flexibility, corrosion resistance and wear resistance. Compared with the full plastic buried drainage pipe with the same diameter and the same ring rigidity, the cost can be significantly reduced. While achieving high performance, its outstanding advantage is saving raw materials. The outer corrugated plastic winding structure wall with hollow reinforcing ribs Pipes are widely used in the construction of municipal sewage pipelines due to their good pipe-soil interaction and ring stiffness. The all-plastic winding bellows equipment is relatively simple, but for large-diame...

Problems solved by technology

The all-plastic winding corrugated pipe equipment is relatively simple, but for pipes with large diameters, the thickness of the plastic layer will become very thick to meet the ring rigidity requirements, and the cost of pipes will increase
