Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, specifically to an enhanced spiral corrugated pipe. Background Technology

[0002] Spiral corrugated pipes, due to their light weight, corrosion resistance, and ease of construction, have been widely used in various fields such as municipal drainage, farmland irrigation, and industrial wastewater treatment. However, in practical use, existing spiral corrugated pipes have significant shortcomings: insufficient structural strength, making them prone to deformation and cracking under external or internal media pressure, severely affecting their service life and safety; furthermore, some products have poor impact resistance and aging resistance, making them difficult to adapt to complex and diverse operating environments. Therefore, this invention proposes an enhanced spiral corrugated pipe to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an enhanced spiral corrugated pipe, which aims to improve the structural strength, impact resistance, and anti-aging properties of the spiral corrugated pipe, thereby extending its service life and ensuring safe use.

[0004] To achieve the above-mentioned utility model objectives, the technical solution provided by this utility model is as follows: an enhanced spiral corrugated pipe, comprising a pipe body, wherein the outer side of the pipe body is provided with spiral protrusions, the spiral protrusions being distributed in a continuous spiral shape on the outer surface of the pipe body; and an inner reinforcing layer is provided inside the pipe body, the reinforcing layer being tightly fitted to the inner wall of the pipe body.

[0005] Furthermore, the spiral protrusion is provided with reinforcing ribs inside, which are arranged along the extension direction of the spiral protrusion and are integrally formed with the spiral protrusion.

[0006] Furthermore, the reinforcing layer includes a base layer, a first impact-resistant layer is provided on the outside of the base layer, an anti-aging layer is provided on the outside of the first impact-resistant layer, and the anti-aging layer is connected to the inner wall of the pipe.

[0007] Furthermore, the tube body is provided with connecting parts at both ends, and the connecting parts are provided with external threads on the outside.

[0008] Furthermore, the tube body is made of high-density polyethylene material, and the reinforcing ribs are made of glass fiber reinforced plastic.

[0009] Furthermore, the first impact-resistant layer is a polycarbonate layer, and the anti-aging layer is a polyethylene layer with added antioxidants and ultraviolet absorbers.

[0010] The advantages of this invention compared to the prior art are as follows: By setting spiral protrusions with reinforcing ribs on the outside of the pipe body, this invention significantly improves the structural strength and ring stiffness of the corrugated pipe, enabling it to withstand greater external pressure and reducing the occurrence of deformation and breakage.

[0011] The internal reinforcement layer of the pipe includes an impact-resistant layer and an anti-aging layer. The impact-resistant layer improves the pipe's impact resistance, making it less susceptible to damage when subjected to external impacts. The anti-aging layer enhances the pipe's anti-aging ability and extends its service life, making it particularly suitable for complex environments such as outdoors.

[0012] The pipe ends are equipped with external threads and sealing rings, which facilitates quick connection between pipes and provides good sealing to effectively prevent media leakage.

[0013] The pipe body is made of high-density polyethylene material and reinforced with glass fiber reinforced plastic ribs, which reduces the weight of the pipe and lowers the construction difficulty while ensuring the performance of the pipe. Attached Figure Description

Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] Combined with appendix Figure 1 To be continued Figure 3 An enhanced spiral corrugated pipe includes a pipe body 1, with spiral protrusions 2 on the outer side of the pipe body 1, the spiral protrusions 2 being distributed in a continuous spiral shape on the outer surface of the pipe body 1; and an enhancement layer 3 is provided inside the pipe body 1, the enhancement layer 3 being tightly fitted to the inner wall of the pipe body 1.

[0020] Furthermore, the spiral protrusion 2 is provided with a reinforcing rib 4 inside, the reinforcing rib 4 is arranged along the extension direction of the spiral protrusion 2, and is integrally formed with the spiral protrusion 2.

[0021] Furthermore, the reinforcing layer 3 includes a base layer 301, a first impact-resistant layer 302 is provided on the outside of the base layer 301, and an anti-aging layer 303 is provided on the outside of the first impact-resistant layer 302. The anti-aging layer 303 is connected to the inner wall of the pipe body 1.

[0022] Furthermore, the tube body 1 is provided with connecting parts 5 at both ends, and the connecting parts 5 are provided with external threads on the outside.

[0023] Furthermore, the tube body 1 is made of high-density polyethylene material, and the reinforcing rib 4 is made of glass fiber reinforced plastic.

[0024] Furthermore, the first impact-resistant layer 302 is a polycarbonate layer, and the anti-aging layer 303 is a polyethylene layer with added antioxidants and ultraviolet absorbers.

[0025] The specific implementation of this utility model is as follows: In the production process of this reinforced spiral corrugated pipe, the pipe body is first made by extrusion molding. At the same time as the pipe body is extruded, a spiral protrusion is formed simultaneously, and a reinforcing rib is embedded inside the spiral protrusion. The reinforcing rib and the spiral protrusion are integrally formed by injection molding, thereby enhancing the structural strength of the spiral protrusion.

[0026] Subsequently, reinforcing layers are sequentially laminated inside the pipe body. First, the base layer is tightly bonded to the inner wall of the pipe body. Then, the first impact-resistant layer is coated on the outside of the base layer. Finally, an anti-aging layer is coated on the outside of the first impact-resistant layer, so that the reinforcing layers are firmly bonded to the pipe body, thereby improving the overall strength, impact resistance and anti-aging performance of the pipe body.

[0027] Connecting parts are machined at both ends of the pipe body, external threads are machined on the outside of the connecting parts, and sealing rings are installed on the inside of the connecting parts to facilitate the connection between pipes and ensure the sealing of the connection.

[0028] In use, the connecting parts of two adjacent corrugated pipes are butted together, and a threaded connection is achieved through external threads. The sealing ring ensures the sealing of the connection and effectively prevents media leakage. The spiral protrusions on the outside of the pipe body and the internal reinforcing ribs can improve the ring stiffness of the pipe and enhance its ability to withstand external pressure. The first impact-resistant layer in the reinforcing layer can improve the impact resistance of the pipe, making it less prone to damage when subjected to external impacts. The anti-aging layer can enhance the anti-aging ability of the pipe and extend its service life in outdoor and other environments.
