DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-2 This application is described in further detail.

[0024] The embodiment of the present application discloses a double high-rib corrugated pipe.

[0025] Reference Figure 1 A double high-rib corrugated pipe includes a pipe body 1, which is formed by spirally winding a long strip of plastic strip. A plurality of winding layers are fixedly wound on the pipe body 1, and the winding layers are fixed to the pipe body 1 by glue. In other embodiments, the winding layers can be directly bonded to the pipe body 1 by hot melting. The winding layer includes a connecting portion 2 and two reinforcing portions 3, and the two reinforcing portions 3 are arranged at both ends of the connecting portion 2. The connecting portion 2 and the two reinforcing portions 3 are integrally formed, and a cavity 31 is arranged in the reinforcing portion 3 to improve the pressure resistance. A reinforcing rib 311 is fixedly arranged in the cavity 31, and one end of the reinforcing rib 311 is fixedly connected to the bottom end of the support plate 35, and the other end is fixedly connected to the top plate 34.

[0026] Among them, refer to Figure 2 The reinforcement part 3 includes an integrally formed side plate 32, a bottom plate 33, a top plate 34 and a support plate 35. The top plate 34 is arranged away from the tube body 1, and the bottom plate 33 is fitted with the tube body 1. The side plates 32 and the support plates 35 are located on both sides of the top plate 34 and the bottom plate 33. The two support plates 35 of two adjacent winding layers are fixedly connected by an adhesive layer 4, and the adhesive layer 4 is made of glue. An extension section 351 is arranged at one end of the support plate 35 away from the tube body 1, and the extension section 351 is integrally formed with the support plate 35. The extension section 351 is higher than the top plate 34, which effectively improves the ring stiffness of the tube body 1 and improves the compressive resistance of the tube body 1. The two extension sections 351 of two adjacent reinforcement parts 3 are bonded together to form a double high-rib structure, which effectively increases the structural stiffness.

[0027] Reference Figure 2 A plurality of protrusions 21 are arranged on the side of the connection part 2 away from the tube body 1. The protrusions 21 are arc-shaped structures, and two adjacent protrusions 21 are connected to each other. The protrusions 21 on the connection part 2 are continuously arranged. The arc-shaped protrusions 21 effectively improve the ring stiffness of the connection part 2, thereby improving the compressive resistance of the tube body 1.

[0028] Reference Figure 2 The side wall of the support plate 35 away from the side plate 32 is provided with a bonding groove 352, and a plurality of bonding grooves 352 are arranged at intervals along the height direction of the support plate 35. The bonding grooves 352 on the two interconnected support plates 35 are staggered, and the bonding grooves 352 are staggered to avoid excessive glue thickness at the bonding grooves 352 and affect the overall strength. In this embodiment, the cross section of the bonding groove 352 is an arc shape, and in other embodiments, the bonding groove 352 can be rectangular, triangular, or other shapes.

[0029] Reference Figure 2 Because the pipeline is subjected to the pressure of the soil for a long time, the bottom of the two adjacent support plates 35 is deformed, which may easily cause the adhesive layer 4 thereto to crack. A connecting strip 5 is connected between the two adjacent reinforcement parts 3, and the connecting strip 5 is made of plastic or steel. Specifically, a groove 331 is provided on the side wall of the bottom plate 33 close to the pipe body 1. The groove 331 is located at one end of the bottom plate 33 close to the adjacent reinforcement part 3. The two ends of the connecting strip 5 are respectively inserted into the groove 331, and the connecting strip 5 is bonded and fixed. A plurality of tooth grooves 3311 are provided on the side wall where the groove 331 abuts against the connecting strip 5. The tooth grooves 3311 are arc-shaped grooves, and may also be rectangular grooves or triangular grooves. The plurality of tooth grooves 3311 are distributed along the axial direction of the pipe body 1, and a plurality of teeth 51 for inserting into the tooth grooves 3311 are provided on the side wall of the connecting strip 5 away from the pipe body 1.

[0030] When the pipeline is subjected to radial and axial pressure, the bottoms of the two adjacent support plates 35, that is, the end of the support plate 35 close to the pipe body 1, tend to move away from each other, and the teeth of the connecting strip 5 engage with the tooth grooves 3311 on the support plate 35 to prevent the support plate 35 from deforming, effectively preventing the two adjacent support plates 35 from cracking, and further improving the overall pressure resistance of the pipe body 1.

[0031] The implementation principle of the embodiment of the present application is as follows: a plurality of winding layers are sequentially wound around the pipe body 1, and the support plates 35 of two adjacent reinforcement parts 3 are fixed as a whole by gluing, a cavity 31 is provided inside the reinforcement part 3 to effectively improve the pressure resistance of the pipe body 1, and an extension section 351 protruding from the top plate 34 is provided on the support plate 35 to further improve the ring stiffness, thereby improving the pressure resistance of the pipe body 1, and a protrusion 21 is provided on the connecting part 2 to effectively improve the structural strength of the connecting part 2, thereby achieving the effect of improving the pressure resistance of the pipeline.

[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
