[0016] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent similar or analogous elements. The following exemplary embodiments described in the following description are not meant to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of the present disclosure as detailed in the appended claims.

[0017] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0018] As shown in Figure 1 and Figure 2 The present embodiment proposes a double-peak multi-rib reinforced winding structure wall pipe, which comprises a pipe body 1 spirally wound by profiled strips, and the profiled strips are bonded and formed into the pipe body 1 under a heated state, the pipe body 1 comprises a hollow protrusion 2 and two side protrusions 3, the height and width of the two side protrusions 3 are 1.5-2.0 times of the hollow protrusion 2 respectively, the inner top wall of the two side protrusions 3 is fixedly connected with an inner reinforcing rib 4, the inner walls of the hollow protrusion 2 and the two side protrusions 3 are fixedly connected with reinforcing rib ribs 5, the two two side protrusions 3 are bonded with a reinforcing rib rib 6, the surface of the pipe body 1 is wrapped with an outer protective layer 7, and the outer protective layer 7 is made of high molecular weight high density polyethylene material.

[0019] The material of the pipe body 1 is high density polyethylene strip-shaped section, and the use of high molecular weight high density polyethylene significantly improves the strength, wear resistance, corrosion resistance and the like of the pipe material, and on this basis, the double-peak reinforcing rib winding pipe structure is optimized to improve the ring stiffness, compressive strength and impact resistance of the pipe material.

[0020] The hollow protrusion 2 is semicircular, and the number of the inner reinforcing rib 4 in the hollow protrusion 2 is two, which are arranged obliquely to support the hollow protrusion 2 and improve the compressive performance and ring stiffness of the hollow protrusion 2, so as to effectively disperse the external pressure of the pipeline and improve the load-carrying capacity of the pipeline.

[0021] The two side protrusions 3 are in the shape of a right-angled trapezoid, and the equal-side trapezoidal structure of the two side protrusions 3 is designed to make the external pressure more evenly distributed on the entire wave crest surface. Compared with the traditional arc-shaped wave crest, the wave crest will not be locally deformed or damaged due to stress concentration at the wave crest vertex. The double-wave-crest structure better disperses the pressure on the wave crest. The inner reinforcing rib 4 in the two side protrusions 3 is arranged at an oblique angle. The top ends of the two side protrusions 3 form a flat wave crest after being bonded. The surface of the flat wave crest is relatively flat. During the flow of the medium, the flat wave crest reduces the turbulence and vortex generated by the wave crest undulation, reduces the wear of the medium on the inner wall of the pipeline, reduces the deposition of impurities in the recess, further reduces the possibility of wear, prolongs the service life of the pipe, and is not prone to deformation or distortion during long-term use, thereby maintaining the shape and size stability of the pipeline, ensuring the normal operation of the pipeline system, reducing the maintenance and replacement costs caused by pipeline deformation, and the thickness of the two side protrusions 3 is consistent with the thickness of the inner reinforcing rib 4, so that after the pipeline is spliced, the thickness of the two inner reinforcing ribs 4 is thicker, which better increases the ring stiffness of the pipe and improves the overall toughness and pressure-bearing capacity of the pipeline.

[0022] Specifically, the double-wave-crest multi-rib reinforced winding structure wall pipe in use: using high molecular weight high density polyethylene to significantly improve the strength, wear resistance, corrosion resistance, etc. of the pipe, on this basis, by optimizing the double-wave-crest reinforcing rib winding pipe structure, the ring stiffness, compressive strength and impact resistance of the pipe are improved. The design of the equal-side trapezoidal structure wave crest makes the external pressure more evenly distributed on the entire wave crest surface. Compared with the traditional arc-shaped wave crest, the wave crest will not be locally deformed or damaged due to stress concentration at the wave crest vertex. The double-wave-crest structure better disperses the pressure on the wave crest. The inner reinforcing rib 4 inside the wave crest further improves the pressure resistance of the pipe, and the inner reinforcing rib 4 inside the wave crest helps to improve the ring stiffness of the pipe. At the same time, the double-wave-crest design enhances the stability of the pipe during underground use. The surface of the flat wave crest is relatively flat. During the flow of the medium, the flat wave crest reduces the turbulence and vortex generated by the wave crest undulation, reduces the wear of the medium on the inner wall of the pipeline, reduces the deposition of impurities in the recess, further reduces the possibility of wear, prolongs the service life of the pipe, and at the same time, the outer layer is wrapped with high molecular weight high density polyethylene material, which can fully utilize the material properties to reduce the external friction coefficient of the pipe, improve the wear resistance and corrosion resistance of the pipe, effectively solve the problem of insufficient strength of the outer wall of the traditional winding pipe to adapt to harsh working conditions such as deep underground drainage and industrial high-pressure conveying pipeline, solve the performance bottleneck of traditional pipes in actual application, and meet the higher performance requirements of modern engineering for pipes.

[0023] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
