[0024] Embodiment one: a kind of anti-cracking PE pipe, as Figure 1 - Figure 4 As shown, including PE pipe main body 100, PE pipe main body 100 is installed in outer tube 200 inner cavity, outer tube 200 inner cavity is also installed with cold-proof anti-cracking mechanism, and cold-proof anti-cracking mechanism includes anti-cracking component 300, and anti-cracking component 300 includes sleeve 301, and four groups of side slots 302 are equally divided in the cavity groove of sleeve 301, and the end face of four groups of side slots 302 is provided with cavity 303, and cold-proof partition piece 304 is installed in the cavity 303, and cold-proof partition piece 304 can be specifically polyurethane foam plastic material, and PE pipe main body 100 is installed in the cavity groove of sleeve 301.

[0025] Through the cooperation of the PE pipe body 100, the outer pipe 200 and the anti-cracking assembly 300, when in cold regions, by installing the PE pipe body 100 in the sleeve pipe 301, the frost heaving stress can be reduced, and the PE pipe body 100 is protected from external damage by the cold-proof partition piece 304 provided in the sleeve pipe 301. At the same time, four groups of side grooves 302 are provided in the sleeve pipe 301, which provide installation positions for the cold-proof partition piece 304, so that the cold-proof partition piece 304 can be tightly attached around the sleeve pipe 301, forming an additional protective layer to effectively prevent the cold-proof partition piece 304 from being scratched and damaged.

[0026] As shown in Figure 1 - Figure 4 The cold-proof partition piece 304 is insertedly installed in the four groups of side grooves 302, and the outer side edge of the cold-proof partition piece 304 is provided with a pull ring 305. During actual assembly, the cold-proof partition piece 304 can be more firmly fixed in the side groove 302, thereby enhancing the stability of the entire structure and helping to reduce the risk of displacement or falling of the cold-proof partition piece 304 due to external factors. At the same time, the design of the pull ring 305 makes it more convenient for the user to insert the cold-proof partition piece 304 into the side groove 302, and also facilitates its removal when needed. Through this design, the installation and maintenance efficiency can be improved, and the operation difficulty is reduced.

[0027] As shown in Figure 1 - Figure 4 The sleeve pipe 301 cavity is also provided with a protection pipe 400, and the PE pipe body 100 is installed in the protection pipe 400.

When installing the protection pipe 400, only the skeleton 401 on four sides of the protection pipe 400 needs to be embedded into the buffer cavity 5 of the sleeve pipe 301. Through the embedded installation mode of the protection pipe 400, the PE pipe body 100 is more stable in the sleeve pipe 301, reducing the displacement or deformation of the pipeline caused by external factors. At the same time, through the design of the protection pipe 400 and the skeleton 401, the overall pressure resistance is enhanced. When subjected to external pressure, the protection pipe 400 can disperse and absorb part of the stress, thereby reducing the direct impact on the PE pipe body 100.
