Description

Technical Field

[0001] The utility model relates to the technical field of double-wall corrugated pipes, and more specifically to a double-wall corrugated pipe with enhanced compression resistance. Background Art

[0002] Double-wall corrugated pipe is a new type of lightweight pipe made of high-density polyethylene. It has the characteristics of light weight, high pressure resistance, good toughness, fast construction and long service life. The outer wall has a ring-shaped corrugated structure, which greatly enhances the ring stiffness of the pipe, thereby enhancing the pipe's resistance to soil load.

[0003] The existing double-wall corrugated pipes still have the following problems: Most of the double-wall corrugated pipes on the market currently rely on their own materials and corrugated structures to improve their own compressive performance. However, in actual use, double-wall corrugated pipes are often buried in the soil, which requires the double-arm corrugated pipes themselves to bear the weight of the soil and the weight of vehicles and personnel above the soil surface. Long-term use only relies on its own materials and corrugated structures to achieve its compressive resistance, and the effect is not ideal. It is very easy to cause the double-wall corrugated pipes to deform due to long-term excessive external pressure, which in turn affects the actual use of double-wall corrugated pipes;

[0004] In addition, the existing double-wall corrugated pipes often need to be butt-jointed during installation and use. In this process, the existing methods are mostly butt-jointed by threads or bolts. This butt-jointing method is not only cumbersome to install and requires the cooperation of multiple people, but also the sealing performance of the butt joint itself is not ideal, which brings many inconveniences to actual use.

[0005] In view of this, we propose a double-wall corrugated pipe with enhanced compression resistance. Utility Model Content
