Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipes, in particular to a reinforced double-wall corrugated pipe. Background Art

[0002] Double-wall corrugated pipe is a new type of pipe with an annular outer wall and a smooth inner wall. It was first successfully developed in Germany in the early 1980s. After more than ten years of development and improvement, it has developed from a single variety to a complete product series. The production process and application technology are very mature. Due to its excellent performance and relatively economical cost, it has been widely promoted and applied in developed countries such as Europe and the United States.

[0003] The existing double-wall corrugated pipe has a hollow structure inside and lacks a supporting reinforcement structure, which causes deformation due to external force impact during transportation. At the same time, it is deformed due to the pressure of backfill soil during use, resulting in low rigidity and short service life. Therefore, a reinforced double-wall corrugated pipe is urgently needed to solve the above problems. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the utility model is aimed at the current status of the prior art, and now provides a reinforced double-wall corrugated pipe with high utilization rate and good use effect.

[0006] (II) Technical solution

[0007] The utility model is achieved through the following technical scheme: the utility model proposes a reinforced double-wall corrugated pipe, including an inner pipe, six groups of reinforcing rods are evenly spaced and circumferentially distributed in the inner pipe, an outer pipe is arranged on the outside of the inner pipe, wave crests and wave troughs are arranged in an array on the surface of the outer pipe, a connecting steel ring is fixed at one end of the inner pipe, and a load-bearing ring is arranged at the other end of the inner pipe.

[0008] Furthermore, the reinforcing rods are welded to the inner wall of the inner tube, and the other ends of the six groups of reinforcing rods are welded and located at the center line of the inner tube.

[0009] By adopting the above technical solution, the six groups of reinforcing rods can form a reinforcing frame inside the inner tube, thereby supporting and reinforcing the inner wall of the inner tube, effectively preventing the insulation tube from being deformed due to impact and excessive pressure, and ensuring the service life and stiffness performance of the corrugated tube.

[0010] Furthermore, the reinforcing rod and the inner wall of the inner tube are sprayed with anti-corrosion paint.

[0011] By adopting the above technical solution, the reinforcement rod and the inner tube can be prevented from being corroded by the liquid in the tube.

[0012] Furthermore, the outer tube is bonded to the inner tube, and the material of the outer tube is polyethylene.

[0013] By adopting the above technical solution, the outer tube can protect the inner tube.

[0014] Furthermore, the wave crests and the wave troughs are both formed on the outer tube.

[0015] By adopting the above technical solution, the wave crests and the wave troughs are combined to form corrugations.

[0016] Furthermore, the connecting steel ring and the bearing rod are welded to the inner tube, and the outer diameter of the connecting steel ring matches the inner diameter of the bearing ring.

[0017] By adopting the above technical solution, during the laying process, the connection of the corrugated pipe can be achieved by placing the connecting steel ring in the bearing ring and welding it.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] In order to solve the problem that the existing double-wall corrugated pipe has a hollow structure inside and lacks a supporting and reinforcing structure, which leads to deformation due to external force impact during transportation, and deformation due to the pressure of backfill soil during use, which leads to low rigidity and short service life, the utility model welds six groups of reinforcing rods at equal intervals on the inner wall of the inner pipe. The six groups of reinforcing rods can form a reinforcing frame inside the inner pipe, which can support and strengthen the inner wall of the inner pipe, effectively prevent the insulation pipe from being deformed due to impact and excessive pressure, and ensure the service life and rigidity performance of the corrugated pipe.
