Description

Technical Field

[0001] The invention relates to the technical field of municipal pipelines, and in particular to a reinforced double-walled highly reinforced special-shaped composite pipe. Background Art

[0002] Power pipes are one of the most widely used municipal pipes. They are generally used for underground pipe installation of power or communication cables to protect cables. Existing power pipes generally adopt a single-layer round pipe structure. The single-layer power pipe is thinner and more prone to wear and tear. When the pipe body is broken, groundwater and soil will enter the pipe body through the cracks, exposing the cable to the soil and water, which will have an adverse effect on the cable. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a reinforced double-walled high-reinforcement special-shaped composite pipe which has a novel structure, strong stability and is easy to process.

[0004] In order to achieve the above objectives, the technical solution adopted by the present invention is: a reinforced double-walled high-reinforcement special-shaped composite pipe, characterized in that it includes a pipe body and a plurality of convex plates formed on the outer wall of the pipe body and arranged along the length direction of the pipe body, wherein the pipe body includes an inner layer tube and an outer layer tube arranged inside and outside, the convex plates are hollow and are formed by inflating the outer layer tube, and an intake pipe extending along the length direction of the pipe body is also connected between each of the convex plates, the intake pipe and the outer layer tube are integrally formed and a bulge structure is formed on the outer surface of the pipe body, wherein the bulge height of the intake pipe matches the height of the convex plate.

[0005] The beneficial effects of the present invention are as follows: the double-walled high-reinforcement special-shaped composite pipe of the present invention has a pipe body composed of an inner layer pipe and an outer layer pipe, and its double-layer structure can improve the structural stability of the pipe body. The convex plate side outside the pipe body can increase the contact area between it and the foundation soil when the pipe is buried, which is beneficial to improve its stability and disperse the pressure on the pipeline. In the present invention, the convex plate is a hollow structure, which can reduce the weight of the pipeline and reduce material consumption to save costs. When processing the convex plate, the hollow structure of the convex plate can be realized by inflating with an inflatable tube, which reduces the difficulty of the process. In addition, since the bulge height of the inflatable tube matches the height of the convex plate, the inflatable tube can be used as a reinforcing rib to further improve the structural stability of the pipeline.

[0006] Furthermore, the inner tube is made of PE and the outer tube is made of PP. After the present invention adopts the above structure, the PP (polypropylene) used in the outer tube has strong wear resistance, while the PE (polyethylene) used in the inner tube has strong toughness and is suitable for maintaining the tube structure.

[0007] Furthermore, the cross section of the convex plate is quadrilateral, hexagonal or octagonal. After the present invention adopts the above structure, the convex plate adopts a polygonal structure and can be used to support the high-reinforced special-shaped composite pipe during construction to prevent the high-reinforced special-shaped composite pipe from rolling and facilitate placement.

[0008] Furthermore, the cross section of the air intake pipe is a semicircular structure.

[0009] Furthermore, the spacings between the convex plates are equal. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution claimed by the present invention will now be further described in detail with reference to the accompanying drawings and specific embodiments.

[0019] Embodiment 1

[0020] See also Figures 1 to 3 As shown, a reinforced double-walled high-reinforcement special-shaped composite pipe in this embodiment includes a pipe body 1 and a plurality of convex plates 2 formed on the outer wall of the pipe body 1 and arranged along the length direction of the pipe body 1.

[0021] The pipe body 1 includes an inner layer pipe 11 and an outer layer pipe 12 arranged inside and outside. In this embodiment, the inner layer pipe 11 is made of PE material, which has strong toughness and is suitable for maintaining the structure of the pipe body 1. The outer layer pipe 12 is made of PP material, which has strong wear resistance. The pipe body 1 is composed of the inner layer pipe 11 and the outer layer pipe 12, and its double-layer structure can improve the structural stability of the pipe body 1.

[0022] The convex plate 2 is hollow and is formed by inflating the outer tube 12. In this embodiment, the cross section of the convex plate 2 is quadrilateral and the spacing between each convex plate 2 is equal. The side of the convex plate 2 outside the pipe body 1 can increase the contact area between it and the foundation soil when the pipe is buried, which is conducive to improving its stability and dispersing the pressure on the pipe. An air intake pipe 3 extending along the length direction of the pipe body 1 is also connected between each of the convex plates 2. The air intake pipe 3 is integrally formed with the outer tube 12 and forms a bulge structure on the outer surface of the pipe body 1. Specifically, the cross section of the air intake pipe 3 is a semicircular structure, wherein the bulge height of the air intake pipe 3 matches the height of the convex plate 2. In this embodiment, there are four air intake pipes 3 and they pass through the four sides of the convex plate 2 respectively, wherein the height difference between the air intake pipe 3 and the edge of the convex plate 2 is 1~2cm. Since the bulge height of the inflation pipe matches the height of the convex plate 2, the inflation pipe can be used as a reinforcing rib to further improve the structural stability of the pipe.
