Problems solved by technology

It was first successfully developed in Germany in the early 1980s. After more than ten years of development and improvement, the promotion and application of double-wall corrugated pipes are on the rise. There are installation difficulties and safety hazards in installation and durability
[0003] In order to solve the above problems, the patent number: CN201720489818.3 proposes an outer octagonal inner circle double-wall bellows, the inner wall of which is a double-wall bellows with a cylindrical structure, which changes the outer wall of the conventional ring structure into a polygon structure to increase the contact area between the outer surface of the pipeline and the foundation in order to solve the above-mentioned problems, but the full polygon outer wall bellows structure proposed in this patent will cause the flexibility of the pipeline to decrease compared with the outer wall bellows of the ring structure. It cannot solve the safety problem, and the force uniformity of the full polygonal outer wall structure will be relatively weak

Abstract

The invention provides an outer multilateral impeller-shaped reinforced composite pipe. The outer multilateral impeller-shaped reinforced composite pipe comprises a pipe body, a spigot and a socket, wherein the spigot and the socket are arranged at two ends of the pipe body respectively, the pipe body comprises an inner layer and an outer layer, the cross section of the inner layer is in a circular ring shape, and the outer layer comprises polygonal circular ring protrusions and corrugated protrusions; and the corrugated protrusions are arranged on the surfaces of the straight edges of the polygonal annular protrusions, the polygonal annular protrusions and the corrugated protrusions are each of a hollow structure, the cross section of the outer layer is in the shape of a polygonal impeller ring, and the cross section of the spigot and the cross section of the socket are each in the shape of a ring. The outer layer of the pipe body is of a multilateral impeller circular ring structure with circular rings and corrugations, so that the contact area of the pipe body and soil can be enlarged, the pipe body has good anti-settling capacity, water and soil loss is prevented, the pipe body further has higher rigidity and higher load resistance, the axial flexibility of traditional double-wall corrugations is reserved, stress is uniform, and collapse caused by local buckling deformation or reverse bending deformation is not liable to occur.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to a polygonal pulsating reinforced composite pipe. Background technique [0002] Double-wall plastic corrugated pipe has a ring-shaped outer wall and a smooth cylindrical inner wall. With its excellent performance, it is widely used in buried drainage pipes, etc. It was first successfully developed in Germany in the early 1980s. After more than ten years of development and improvement, the promotion and application of double-wall corrugated pipes are on the rise. There are installation difficulties and safety hazards in terms of installation and durability. [0003] In order to solve the above problems, the patent number: CN201720489818.3 proposes an outer octagonal inner circle double-wall bellows, the inner wall of which is a double-wall bellows with a cylindrical structure, which changes the outer wall of the conventional ring structure into a polygon structure to increa...
