Description

Technical Field

[0001] This utility model belongs to the field of PE pipe technology, specifically a pre-embedded anti-corrosion high-strength PE pipe. Background Technology

[0002] In municipal engineering, building water supply and drainage, and underground pipeline laying, PE pipes are widely used in pre-buried pipeline construction due to their advantages such as light weight, good toughness, and relatively low cost. However, with the increasing complexity of pre-buried scenarios and the ever-increasing requirements for pipeline service life and safety stability, traditional PE pipes have gradually exposed a series of problems that urgently need to be solved in practical applications, becoming key bottlenecks restricting their further promotion and application.

[0003] Pre-buried PE pipes are constantly exposed to the underground soil environment, where moisture, salt, acids, alkalis, and microorganisms continuously come into contact with and interact with the pipe surface. Although traditional PE pipes possess a certain degree of corrosion resistance, during long-term underground service, their surface is susceptible to penetration and erosion by corrosive substances in the soil, leading to aging, cracking, and ultimately compromising the structural integrity of the pipe.

[0006] The beneficial effects of this utility model are as follows: 1. This utility model, by setting up an anti-corrosion pipe, utilizes the excellent anti-corrosion properties of the anti-corrosion pipe to fundamentally prevent direct contact between corrosive media and the surface of the PE pipe, effectively ensuring the structural integrity of the PE pipe, significantly extending its service life, and achieving the purpose of good anti-corrosion effect; at the same time, the reinforcing mesh fixedly connected to the surface of the anti-corrosion pipe can significantly enhance the overall structural strength of the anti-corrosion pipe, and can effectively resist soil pressure and external impact in buried laying scenarios.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] like Figures 1 to 6 As shown, the present invention provides a pre-embedded anti-corrosion high-strength PE pipe, comprising: PE pipe 1, reinforcing mesh 2, anti-corrosion pipe 3, connecting disc 4, and through hole 5; The anti-corrosion pipe 3 is fixedly connected to the surface of the PE pipe 1. Through its excellent anti-corrosion properties, the anti-corrosion pipe 3 can effectively prevent corrosive media from directly contacting the surface of the PE pipe 1, thus preventing the PE pipe 1 from being eroded by corrosive media from the source and ensuring the structural integrity and service life of the PE pipe 1. The reinforcing mesh 2 is fixedly connected to the surface of the anti-corrosion pipe 3. The reinforcing mesh 2 can significantly enhance the overall structural strength of the anti-corrosion pipe 3. Especially in the scenario of burying the anti-corrosion pipe 3, it can effectively resist soil pressure and external impact, prevent the anti-corrosion pipe 3 from deforming and breaking, and further provide stable protection for the PE pipe 1.

[0013] refer to Figure 5 PE pipe 1 includes pipe 101, a connecting pipe 102 is fixedly connected to the surface of pipe 101, and a protective pipe 103 is fixedly connected to the surface of connecting pipe 102.

[0014] In this embodiment, the PE pipe 1 can serve as the core channel for transporting the medium, ensuring normal transport of the medium. The connecting pipe 102, which is fixedly connected to the surface of the pipe 101, can enhance the connection stability between the pipe 101 and the protective pipe 103, preventing them from loosening during long-term use.

[0015] refer to Figure 2 The reinforcing mesh 2 includes a steel ring 21, inside which is a stainless steel plate 22, inside which is a fiberglass sleeve 23, and inside which is a polypropylene strip 24.

[0016] In this embodiment, by setting up a reinforcing mesh 2, a basic support frame can be provided to enhance the overall structural rigidity; the stainless steel plate 22 inside further improves the tensile and impact resistance and prevents breakage under stress.

[0017] refer to Figure 6 The anti-corrosion pipe 3 includes an epoxy resin layer 31, the surface of which is fixedly connected to a polypropylene strip 24, the interior of a steel ring 21 is fixedly connected to the surface of the epoxy resin layer 31, a petroleum asphalt layer 32 is fixedly connected to the interior of the epoxy resin layer 31, an epoxy coal tar pitch 33 is fixedly connected to the interior of the petroleum asphalt layer 32, a polyethylene adhesive tape layer 34 is fixedly connected to the interior of the epoxy coal tar pitch 33, a steel strip 35 is fixedly connected to the interior of the polyethylene adhesive tape layer 34, and the interior of the polyethylene adhesive tape layer 34 is fixedly connected to the surface of the protective pipe 103.

[0018] In this embodiment, by setting the anti-corrosion pipe 3, the anti-corrosion effect of the PE pipe 1 can be increased. The polyethylene adhesive tape layer 34 can enhance the sealing and anti-corrosion effect, and the internal steel strip 35 can also improve the structural strength of the anti-corrosion pipe 3 and prevent deformation by external forces.

[0019] refer to Figure 1The through hole 5 is opened on the outside of the connecting plate 4. The connecting plate 4 is set on the front and back of the protective tube 103. The inside of the connecting plate 4 is fixedly connected to the front and back of the protective tube 103. The front and back of the stainless steel plate 22 are fixedly connected to the connecting plate 4.

[0020] In this embodiment, by setting through holes 5 and connecting plates 4, an installation channel can be provided for connecting bolts to ensure the pipeline connection is stable. The connecting plates 4 are set on both sides of the protective pipe 103 and fixed to the protective pipe 103 and stainless steel plate 22. This can not only strengthen the connection between the protective pipe 103 and the reinforcing mesh 2, but also seal and protect the pipeline end, reduce the intrusion of corrosive media, and improve the overall structural integrity of the pipeline.

[0021] refer to Figure 1 A sealing ring 6 is provided inside the connecting plate 4, and the surface of the sealing ring 6 is in contact with the inside of the connecting plate 4.

[0022] In this embodiment, by setting a sealing ring 6, the gap between the connecting plate 4 and the adjacent components can be filled, enhancing the sealing of the pipeline connection, preventing leakage of the transported medium, preventing the intrusion of external corrosive media, and further improving the pipeline sealing and anti-corrosion effect.

[0023] refer to Figure 5 A rubber ring 7 is installed inside the pipe 101, and the surface of the rubber ring 7 is fixedly connected to the pipe 101 with waterproof adhesive.

[0024] In this embodiment, by setting the rubber ring 7, the internal sealing of the pipe 101 can be enhanced, and the medium can be prevented from leaking from the interface or gap during medium transportation; at the same time, the rubber ring 7 is elastic, which can buffer the impact of the medium flow on the inner wall of the pipe 101, reduce wear and extend the service life of the pipe 101.

[0025] refer to Figure 6 A protruding plate 8 is fixedly connected to the right side of the inner wall of the polyethylene adhesive tape layer 34. The right side of the protruding plate 8 penetrates the protective tube 103 and extends into the interior of the protective tube 103. The surface of the protruding plate 8 is fixedly connected to the protective tube 103.

[0026] This embodiment sets up a convex plate 8 to form an "anchoring" structure, which greatly enhances the connection strength between the two and avoids relative displacement caused by external forces or environmental factors during long-term use. This ensures the stable connection between the anti-corrosion pipe 3 and the PE pipe 1 and guarantees the continuous effectiveness of the anti-corrosion protection function.

[0027] PE pipe 1 is the core transportation unit of the pipeline, with its internal pipe 101 directly transporting the medium and providing a stable channel. The connecting pipe 102 on the surface of pipe 101 is fixed to the protective pipe 103, forming a three-layer nested structure of "pipe 101-connecting pipe 102-protective pipe 103", which avoids direct contact and wear between pipe 101 and the external structure. To solve the problem of buried corrosion, the pipeline adopts a multi-layer anti-corrosion structure of "inner protection + outer barrier": the anti-corrosion pipe 3 wraps the protective pipe 103, the outermost epoxy resin layer 31 has excellent adhesion and corrosion resistance, the inner petroleum asphalt layer 32 and epoxy coal tar 33 have strong anti-permeability, forming a triple barrier, which greatly reduces the penetration rate of corrosive media. The polyethylene adhesive tape layer 34 inside the epoxy coal tar 33 is attached to the protective pipe 103 to enhance the sealing. To prevent the intrusion of corrosive media, the internal steel bars 35 also support the anti-corrosion pipe 3, preventing its deformation and cracking of the anti-corrosion layer, and ensuring the integrity of the anti-corrosion structure. In response to the pressure of buried soil and external impact, the reinforcing mesh 2 provides rigid protection through "frame support + multi-layer reinforcement": the outermost steel bar ring 21 surrounds the epoxy resin layer 31 in a ring, forming a rigid frame to bear and disperse soil pressure, preventing the anti-corrosion pipe 3 from denting. The internal stainless steel plate 22 is mesh-like, which enhances tensile strength and prevents breakage. Its high hardness can block impact. The glass fiber sleeve 23 inside the stainless steel plate 22 has good weather resistance and protects the polypropylene strip 24 to help disperse stress. The lightweight and high-strength polypropylene strip 24 fills the gaps in the glass fiber sleeve 23, forming a composite structure to improve the toughness of the reinforcing mesh 2, prevent brittleness, and ensure long-term structural strength.
