[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0026] A multi-layer protective wall for a PE pipe, including an outer protective pipe 1, a connecting pipe 2 is inserted and connected to the inner pipe wall of the outer protective pipe 1, a support pipe 3 is inserted and connected to the inner pipe wall of the connecting pipe 2, a heat-insulating filler 8 is filled between the connecting pipe 2 and the support pipe 3, a reinforcing pipe 4 is inserted and connected to the inner pipe wall of the support pipe 3, a clamping pipe 5 is inserted and connected to the inner pipe wall of the reinforcing pipe 4, a first reinforcing layer 7 is fixedly connected to the outer surface of the reinforcing pipe 4, and a first adhesion layer 6 is fixedly connected to the inner pipe wall of the clamping pipe 5.

[0027] In this embodiment, the connecting pipe 2 includes a first pipe body 21, a second reinforcing layer 22 is fixedly connected to the inner pipe wall of the first pipe body 21, a second adhesion layer 23 is fixedly connected to the outer surface of the first pipe body 21, the first pipe body 21 is sleeved with the support pipe 3; the second adhesion layer 23 is adhesively and fixedly connected to the inner pipe wall of the outer protective pipe 1.

[0028] Through the above solution: The connection between the outer protection pipe 1 and the support pipe 3 can be strengthened through the connecting pipe 2. The heat insulation filler 8 filled between the connecting pipe 2 and the support pipe 3 can provide heat insulation protection for the entire PE pipe, improving stability. The connecting pipe 2 can be supported and fixed by adhesively fixing it to the outer protection pipe 1 through the second adhesive layer 23. The entire PE pipe can be reinforced and supported through the connecting pipe 2, improving stability.

[0029] In this embodiment, the clamping pipe 5 includes a second pipe body 51. An adhesive glue 52 is fixedly connected to the outer surface of the second pipe body 51. A corrosion-resistant layer 53 is fixedly connected to the inner pipe wall of the second pipe body 51. The second pipe body 51 is inserted and connected with the reinforcement pipe 4. The first reinforcement layer 7 is adhesively and fixedly connected to the inner pipe wall of the support pipe 3. The first adhesive layer 6 is adhesively and fixedly connected to the outer surface of the clamping pipe 5.

[0030] Through the above solution: The entire PE pipe can be protected against corrosion through the clamping pipe 5. The connection between the clamping pipe 5 and the reinforcement pipe 4 can be facilitated through the adhesive glue 52, improving stability. The PE pipe can be protected against corrosion through the corrosion-resistant layer 53 inside the clamping pipe 5, improving stability.

[0031] It should be noted that the present utility model is a multi-layer protective wall for a PE pipe. During use, the support pipe 3 serves as the main load-bearing part of the entire protective wall and is closely connected to the reinforcement pipe 4 through the first reinforcement layer 7. This connection method enhances the overall strength and stability of the pipe, ensuring the structural integrity under various use environments. The first adhesive layer 6 is used to adhesively fix the reinforcement pipe 4 and the clamping pipe 5. This connection method not only enhances the bonding force between the reinforcement pipe 4 and the clamping pipe 5 but also enables the clamping pipe to play its fixing and supporting roles more effectively, further improving the stability of the pipe. The second adhesive layer 23 on the connecting pipe 2 is closely adhered to the inner pipe wall of the outer protection pipe 1, forming a closed and stable protective layer. This connection method effectively prevents external factors from eroding and damaging the inside of the pipe, improving the service life and safety of the pipe. The connecting pipe 2 and the support pipe 3 jointly support the heat insulation filler 8, ensuring that the heat insulation filler 8 can be evenly distributed inside the pipe, thereby achieving a good heat insulation effect. The presence of the heat insulation filler 8 reduces the influence of the temperature difference inside and outside the pipe on the pipe performance, improving the stability of the pipe under extreme temperature conditions. The corrosion-resistant layer 53 can resist the erosion of various corrosive substances, extending the service life of the pipe. This design enables the pipe to maintain good performance in harsh use environments.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
