[0001] The utility model relates to the field of PE pipelines, in particular to an impact-resistant high-toughness PE pipeline. Background Art

[0002] PE resin is made by polymerizing the monomer ethylene. Due to different polymerization reaction conditions such as pressure and temperature during polymerization, resins of different densities can be obtained. Therefore, it is divided into high-density polyethylene, medium-density polyethylene and low-density polyethylene. PE pipes are widely used in various fields, among which water pipes and gas pipes are its two largest application markets.

[0012] Preferably, both the first elastic member and the second elastic member are of a "snake-shaped" structure, and the end surfaces to which the two are attached cooperate with each other.

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0026] like Figure 1-3 As shown, the utility model provides an impact-resistant high-toughness PE pipe, comprising an inner pipe 1 and an outer pipe 2 arranged from the inside to the outside, with an interlayer left between the inner pipe 1 and the outer pipe 2;

[0029] The separation mechanism includes a separation ring frame 51 arranged on both sides of the first support ring 31 and the second support ring 41.

The guide hole 54 is penetrated by a limiting rod 6 that passes through the first limiting hole 32 and the second limiting hole 42.

The two members are clamped by the first support ring 31 and the second support ring 41, which squeeze the first elastic member 33 and the second elastic member 43 to fill the interlayer between the two.

The limiting rod 6 passes through the guide hole 54 of the separation ring frame 51, and respectively passes through the first limiting hole 32 and the second limiting hole 42 of the first support ring 31 and the second support ring 41, so that the separated support mechanisms are connected in series as a whole. After the pipeline is cut off, the remaining limiting rod 6 can serve as a lateral support mechanism to ensure its stable impact resistance.

[0035] As an installation example of the separation ring frame 51 : one end of the separation ring frame 51 is connected to the inner tube 1 through the inner tube connecting ring 52 , and the other end is connected to the outer tube 2 through the outer tube connecting ring 53 .
