Description

Technical Field

[0001] This application relates to the field of corrugated wall pipe technology, and in particular to HDPE hollow reinforced corrugated AB type spiral wound pipe. Background Technology

[0002] In the field of drainage and fluid transportation pipelines, traditional pipe materials have many limitations in terms of structural strength, material utilization, and functionality. Currently widely used single-walled pipes, such as ordinary Type A pipes, often employ a solid or single-layer design. To meet external pressure strength requirements, the pipe wall thickness often needs to be increased, leading to high material consumption and heavy pipes. This not only increases transportation costs but also causes inconvenience in construction and installation. Furthermore, a single structure is difficult to effectively distribute external pressure, making it prone to deformation and cracking under complex conditions such as rainwater erosion and soil compression, thus shortening the pipe's service life. While some traditional corrugated pipes possess certain pressure resistance, the lack of a reasonable internal reinforcement structure still results in insufficient structural stability when subjected to large external loads.

[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0004] To address the problem that currently widely used single-structure pipes, such as ordinary type A pipes, are unable to effectively distribute external pressure and are prone to deformation and cracking under complex working conditions such as rainwater erosion and soil compression, thus shortening the service life of the pipes, this application provides HDPE hollow reinforced corrugated type AB spiral wound pipe.

[0005] The HDPE hollow reinforced corrugated AB type spiral wound pipe provided in this application adopts the following technical solution:

[0006] HDPE hollow reinforced corrugated AB type spiral wound pipe includes an inner pipe wall and a composite spiral wound wall pipe arranged in a spiral distribution on the outer wall of the inner pipe wall. The composite spiral wound wall pipe includes an A type pipe and a B type inner pipe. The B type inner pipe is composed of B type inner pipe one and B type inner pipe two. An adhesive vertical rib is provided between each two adjacent composite spiral wound wall pipes.

[0007] Preferably, the inner walls at the top ends of the first and second type B inner tubes are set in an arc shape.

[0008] Preferably, the type B inner tube one and type B inner tube two are symmetrically distributed in the type A tube.

[0009] Preferably, the bottom ends of the first type B inner tube and the second type B inner tube extend into the type A tube to form an integral structure with the type A tube.

[0010] Preferably, the points where the Type B inner tube 1 and Type B inner tube 2 contact the inner wall of the Type A tube are provided with central reinforcing ribs to improve the connection strength.

[0011] Preferably, a hollow cavity is formed at the center of the A-type tube, and the hollow cavity includes hollow inner walls symmetrically distributed within the B-type inner tube one and the B-type inner tube two.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The composite spiral wound pipe in this application, composed of type B inner tubes (Type I and II) and type A tube, along with a central reinforcing rib, significantly enhances external pressure resistance, effectively resisting external loads in rainwater and drainage scenarios, ensuring the pipeline's stability and durability. The smooth design of the inner tube wall greatly reduces fluid transport resistance, ensuring efficient transmission. The hollow structure formed by the hollow cavity and hollow inner wall reduces pipe weight while maintaining strength, facilitating transportation and installation. It also absorbs fluid impact and reduces noise. Furthermore, the composite spiral wound pipe employs a glue-injection spiral winding process, creating a stable and continuous pipe structure, further enhancing the overall stability of the pipeline.

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses HDPE hollow reinforced corrugated AB type spiral wound pipe. (Refer to...) Figure 1The system comprises an inner pipe wall 4 and a composite spiral-wound pipe 1 arranged spirally on the outer wall of the inner pipe wall 4. The composite spiral-wound pipe 1 includes a type A pipe 7 and a type B inner pipe, with an adhesive rib 3 between each pair of adjacent composite spiral-wound pipes 1. The smooth surface design of the inner pipe wall 4 significantly reduces resistance during fluid transportation, ensuring that fluids such as water and sewage can pass through quickly and smoothly, improving pipeline transportation efficiency and reducing the risk of blockage. Through an adhesive injection process, adjacent composite spiral-wound pipes 1 are bonded together and spirally wound using the adhesive ribs 3, constructing a continuous and stable pipeline structure, enhancing the overall integrity and fracture resistance of the pipeline, and further improving the pipeline's durability and reliability. The type A pipe 7 and the type B inner pipe can be made of HDPE, PP, or FRPP materials.

[0020] like Figures 2-3 As shown, the type B inner tube is composed of type B inner tube 1 5 and type B inner tube 2 6. The inner walls of the top ends of type B inner tube 1 5 and type B inner tube 2 6 are set in an arc shape. Type B inner tube 1 5 and type B inner tube 2 6 are symmetrically distributed in type A tube 7. The bottom ends of type B inner tube 1 5 and type B inner tube 2 6 extend into type A tube 7 and form an integral structure with type A tube 7.

[0021] In this application, central reinforcing ribs 9 are provided at the contact points between the inner walls of Type B inner tube 5 and Type B inner tube 6 and the inner wall of Type A tube 7 to improve the connection strength. This forms a three-dimensional support system, which effectively disperses external pressure, enhances the connection strength of each component, and significantly improves the overall external pressure strength of the pipeline. This allows it to stably withstand external loads in pressure-bearing scenarios such as rainwater and drainage, reducing the risk of deformation and damage, and extending its service life.

[0022] In this application, a hollow cavity 2 is formed at the center of the interior of the type A pipe 7. The hollow cavity 2 includes hollow inner walls 8 symmetrically distributed within the type B inner pipe 5 and type B inner pipe 6. The hollow structure formed by the hollow cavity 2 and the hollow inner walls 8 significantly reduces material usage while maintaining pipe strength, resulting in a substantial reduction in pipe wall thickness and weight. This not only reduces transportation costs but also makes pipe installation easier and more convenient, reducing construction difficulty and labor costs, and improving construction efficiency.

[0023] The implementation principle of the HDPE hollow reinforced corrugated AB type spiral wound pipe in this application embodiment is as follows:

[0024] Type B inner tube 1 (5) and Type B inner tube 2 (6) are symmetrically distributed inside type A tube 7, extending at the bottom to form an integral structure with type A tube 7. The top is designed as a cat-ear-shaped arc structure. Adjacent composite spiral wound tubes 1 are bonded together by adhesive ribs 3 using an injection molding process, and then spirally wound to form a stable and continuous pipe structure. The inner tube wall 4 serves as the direct channel for fluid transportation, and its smooth surface reduces fluid flow resistance, ensuring smooth fluid passage.

[0025] The central reinforcing rib 9 is located at the contact point between the inner walls of the type B inner tube and the type A tube 7, enhancing the connection strength between components and improving the overall external pressure resistance of the pipeline. The arc-shaped structures of type B inner tube 1 (5) and type B inner tube 2 (6) work synergistically with the central reinforcing rib 9 to effectively disperse external pressure. In pressure-bearing scenarios such as rainwater or drainage pipes, they can better withstand external loads, preventing pipe deformation or damage. The hollow cavity 2 and hollow inner wall 8 form a hollow structure, significantly reducing material usage while ensuring pipeline strength. Compared to a single type A tube 7, the wall thickness is significantly reduced, lightening the pipeline weight and facilitating transportation and installation. Simultaneously, the hollow structure also provides a buffering effect, absorbing the impact force generated by fluid flow and reducing water flow noise.
