Description

Technical Field

[0001] This utility model relates to the field of HDPE pipe technology, specifically to HDPE internally ribbed multi-hole reinforced spiral pipe. Background Technology

[0002] HDPE spiral wound pipes are widely used in municipal drainage, sewage treatment, and industrial fluid transportation due to their advantages such as light weight, corrosion resistance, and long service life. However, traditional HDPE spiral wound pipes often have simple corrugated external rib structures with limited support strength. Under external soil pressure, vehicle loads, or other forces, they are prone to deformation, collapse, or even rupture, leading to pipe damage, fluid leakage, and affecting normal pipeline use, increasing maintenance costs and safety hazards. Furthermore, some HDPE spiral wound pipes with reinforced external rib structures exhibit poor bonding stability between the external ribs and the pipe body during the molding process, leading to rib detachment after long-term use, further reducing the overall performance of the pipeline. Therefore, we provide an HDPE spiral wound pipe that effectively enhances the support strength of the external ribs, has a stable structure, and excellent molding effect to meet the high-strength requirements of practical engineering applications. Utility Model Content

[0003] The purpose of this invention is to provide an HDPE internally ribbed multi-hole reinforced spiral pipe to solve the problems mentioned in the background art, such as insufficient external rib support strength, easy deformation and damage, and poor stability of the external rib and pipe body of traditional HDPE spiral pipes.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] HDPE internally ribbed multi-hole reinforced spiral pipe, including pipe body and plastic corrugated profile;

[0006] The corrugated plastic profile is spirally wound around the outside of the tube body to form an outer corrugated shape;

[0007] The corrugated plastic profile includes a body, reinforcing ribs, and vertical ribs, and the body, reinforcing ribs, vertical ribs, and tube body are co-extruded composite molded together.

[0008] The reinforcing ribs are provided in two sets, and the two sets of reinforcing ribs are respectively provided on both sides of the inner wall of the body. The bottom width of the reinforcing ribs is greater than the top width, and the reinforcing ribs are set as arc-shaped structures that fit with the inner wall of the body.

[0009] The vertical rib is located in the middle of the body, and both ends of the outer wall of the vertical rib are provided with arc-shaped protrusions.

[0010] In a preferred embodiment of this utility model, the top of the vertical rib is provided with a top head, and the top of the top head is connected to the top of the inner wall of the body.

[0011] In a preferred embodiment of this utility model, the bottom of both ends of the top head is provided with an arc-shaped chamfer; and a through hole is provided in the middle of the vertical rib.

[0012] In a preferred embodiment of this utility model, the radius of curvature of the reinforcing rib arc structure is the same as the radius of curvature of the inner wall of the body.

[0015] In a preferred embodiment of this utility model, the through hole in the middle of the vertical rib is circular or elliptical.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0017] In the corrugated plastic profile, the two sets of reinforcing ribs adopt a design of "wide at the bottom, narrow at the top, and curved to fit the body," which not only expands the contact area with the body but also tightly fits the inner wall to form stable support, effectively dispersing the radial pressure of the pipe and preventing local deformation of the body. The middle vertical rib, combined with symmetrical arc-shaped protrusions, further widens the support surface and enhances the bending and shear resistance. Combined with the connection between the top end and the top of the body, a "triangular support structure" is formed, allowing the outer ribs to form a three-dimensional pressure-bearing system. When facing external forces such as soil compression and vehicle loads, the deformation rate is reduced compared to traditional pipes, thus improving the overall performance and service life of HDPE spiral pipes.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] Please refer to Figure 1-2 HDPE internally ribbed multi-hole reinforced spiral pipe, including pipe body 100 and plastic corrugated profile 200;

[0024] The corrugated plastic profile 200 is spirally wound around the outside of the tube body 100 to form an outer corrugated shape;

[0025] The corrugated plastic profile 200 includes a body 300, reinforcing ribs 400 and vertical ribs 500, and the body 300, reinforcing ribs 400, vertical ribs 500 and tube 100 are co-extruded composite molded together.

[0026] Two sets of reinforcing ribs 400 are provided, and the two sets of reinforcing ribs 400 are respectively provided on both sides of the inner wall of the body 300. The reinforcing ribs 400 are set as arc-shaped structures that fit against the inner wall of the body 300. The setting of the reinforcing ribs 400 improves the side wall support of the body 300. The bottom width of the reinforcing ribs 400 is greater than the top width, which further improves the support stability of the reinforcing ribs 400 for the body 300. When the pipe is subjected to external radial pressure, the reinforcing ribs 400 can effectively disperse the pressure and prevent the body 300 from undergoing local deformation.

[0027] The vertical rib 500 is located in the middle of the body 300. Both ends of the outer wall of the vertical rib 500 are provided with arc-shaped protrusions 600. This structure can further enhance the bending resistance and shear resistance of the vertical rib 500, disperse external forces, and improve the overall support performance of the outer rib. The arc-shaped protrusions 600 can also play a certain buffering role when the pipe is subjected to axial force, reducing wear at the connection between the vertical rib 500 and the body 300.

[0028] The top of the vertical rib 500 is provided with a top head 800, and the top of the top head 800 is connected to the top of the inner wall of the body 300.

[0029] The bottom of both ends of the top head 800 is provided with an arc-shaped chamfer 900; the vertical rib 500 has a through hole 700 in the middle. The arc-shaped chamfer 900 can effectively eliminate stress concentration at the connection between the top head 800 and the vertical rib 500, and improve the structural stability and service life of this part.

[0030] The radius of curvature of the arc-shaped structure of the reinforcing rib 400 is the same as the radius of curvature of the inner wall of the body 300, ensuring that the reinforcing rib 400 and the inner wall of the body 300 are tightly fitted without gaps, thereby improving the bonding strength between the two and avoiding stress concentration during the stress process.

[0031] The arc-shaped protrusions 600 at both ends of the outer wall of the vertical rib 500 are symmetrically distributed. The height of the arc-shaped protrusions 600 is 3-8mm, preferably 7mm, and the width is 5-12mm, preferably 11mm.

[0032] The cross-section of the top head 800 is trapezoidal, and the top width of the top head 800 is adapted to the top width of the inner wall of the body 300.

[0033] The through hole 700 in the middle of the vertical rib 500 is circular or elliptical, preferably elliptical. The through hole 700 can reduce the weight of the plastic corrugated profile 200 and save raw materials without affecting the supporting strength of the vertical rib 500. At the same time, it facilitates heat dissipation of the pipe during the molding process and reduces internal stress.

[0034] The working principle of this utility model is as follows: through co-extrusion composite molding technology, the plastic corrugated profile 200 is tightly bonded to the pipe body 100, ensuring the connection stability between the outer rib and the pipe body 100; using two sets of bottom-wide, top-narrow, arc-shaped reinforcing ribs 400, the support strength on both sides of the body 300 is enhanced, preventing local deformation of the body 300; the middle vertical rib 500, together with the arc-shaped protrusion 600 and the top head 800, forms a multi-directional support structure, improving the overall rigidity and resistance to external forces of the plastic corrugated profile 200; the through holes 700 on the vertical rib 500, while reducing weight and saving materials, optimizes the heat dissipation effect during the pipe forming process and reduces internal stress.

[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
