Description

Technical Field

[0001] This utility model relates to the field of composite pipes, specifically to a PP and PE mixed steel wire composite corrugated pipe. Background Technology

[0002] Composite spiral wound pipes are made through composite molding and secondary winding, giving them strong impact resistance. They have high requirements for ground bearing capacity and are suitable for construction environments requiring high-strength support.

[0003] While existing PP and PE composite corrugated pipes have a certain compressive strength, this strength still needs to be further improved; otherwise, they are prone to cracking under heavy stress, leading to quality problems.

[0004] Therefore, it is necessary to invent a composite corrugated pipe made of PP and PE mixed steel wire. Utility Model Content

[0007] Preferably, both the core tube and the first reinforcing layer are made of PE material, the first reinforcing layer is wound and hot-melted fixed to the outer surface of the core tube, and the cross-section of the first reinforcing layer is a solid arch shape.

[0008] Preferably, the spiral composite tube is made of PP material, and the inner surface of the spiral composite tube is wound and hot-melted to the outer surface of the first reinforcing layer.

[0009] Preferably, the second reinforcing layer is made of steel wire, and the number of steel wires is at least one. The second reinforcing layer is wound and fixed around the outside of the wound composite pipe.

[0010] Preferably, the corrugated composite layer is made of PE material, the corrugated composite layer is wound and hot-melted fixed to the outer surface of the first reinforcing layer, and the wound composite pipe and the second reinforcing layer are both hot-melted fixed inside the corrugated composite layer.

[0011] Preferably, the third reinforcing layer is made of PE material, and the third reinforcing layer is wound and hot-melted fixed to the outer surface of the core tube. The cross-section of the third reinforcing layer is a solid arch or a hollow arch.

[0012] The beneficial effects of this utility model are: by using the core tube, the first reinforcing layer, the wound composite tube, the second reinforcing layer, the corrugated composite layer and the third reinforcing layer in combination, not only can the compressive strength of the PP and PE mixed composite corrugated pipe be strengthened in terms of structure, but also the compressive strength of the PP and PE mixed composite corrugated pipe can be strengthened by using composite steel wire, which is beneficial to the stability of the PP and PE mixed composite corrugated pipe.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example 1:

[0022] Please refer to the appendix. Figures 1-4The PP and PE mixed steel wire composite corrugated pipe provided by this utility model includes a core tube 1. Several first reinforcing layers 2 are uniformly fixed on the outer surface of the core tube 1. A wound composite tube 3 is fixed on the outer surface of each of the first reinforcing layers 2. A second reinforcing layer 4 is wound on the outer surface of each of the wound composite tubes 3. A corrugated composite layer 5 is also fixed on the outer surface of the first reinforcing layer 2. The wound composite tube 3 and the second reinforcing layer 4 are both fixed inside the corrugated composite layer 5. A third reinforcing layer 6 is provided between two adjacent corrugated composite layers 5. The third reinforcing layer 6 is fixed on the outer surface of the core tube 1.

[0023] Both the core tube 1 and the first reinforcing layer 2 are made of PE material. The first reinforcing layer 2 is wound and hot-melted fixed to the outer surface of the core tube 1. The cross-section of the first reinforcing layer 2 is a solid arch shape. Specifically, under the reinforcing effect of the first reinforcing layer 2, the compressive strength of the PP and PE mixed composite corrugated pipe can be strengthened in terms of structure.

[0024] The spiral composite pipe 3 is made of PP material. The inner surface of the spiral composite pipe 3 is wound and hot-melted to the outer surface of the first reinforcing layer 2. Specifically, the PP pipe and the PE pipe form a spiral composite pipe.

[0025] The second reinforcing layer 4 is made of steel wire, with at least one steel wire. The second reinforcing layer 4 is wound and fixed around the outside of the wound composite pipe 3. Specifically, the compressive strength of the PP and PE mixed composite corrugated pipe can be enhanced by winding composite steel wire.

[0026] The corrugated composite layer 5 is made of PE material. The corrugated composite layer 5 is wound and hot-melted fixed to the outer surface of the first reinforcing layer 2. The wound composite pipe 3 and the second reinforcing layer 4 are both hot-melted fixed inside the corrugated composite layer 5. Specifically, this structure makes the corrugated composite layer 5, the first reinforcing layer 2 and the core pipe 1 hot-melted into an integrated PE pipe. The corrugated composite layer 5 covers the wound composite pipe 3 and the second reinforcing layer 4, improving the overall aesthetics. Moreover, the corrugated composite layer 5 is corrugated, which can also strengthen the compressive strength of the PP and PE mixed composite corrugated pipe in terms of structure.

[0027] The third reinforcing layer 6 is made of PE material. The third reinforcing layer 6 is wound and hot-melted fixed to the outer surface of the core tube 1. The cross-section of the third reinforcing layer 6 is a solid arch shape. Specifically, the third reinforcing layer 6 can structurally enhance the compressive strength of the PP and PE mixed composite corrugated pipe.

[0028] The process of using this utility model is as follows: The operator first makes the core tube 1, then winds the first reinforcing layer 2 and fixes it with heat fusion, then winds the composite tube 3 and the second reinforcing layer 4, and then winds the outer layer of the corrugated composite layer 5 and fixes it with heat fusion to form the wound composite tube. Finally, the third reinforcing layer 6 is wound around the outer surface of the core tube 1 and fixed with heat fusion.

[0029] Example 2:

[0030] Please refer to the appendix. Figures 5-6 The PP and PE mixed steel wire composite corrugated pipe provided by this utility model has a third reinforcing layer 6 made of PE material. The third reinforcing layer 6 is wound and hot-melted fixed on the outer surface of the core tube 1. The cross-section of the third reinforcing layer 6 is hollow arched. Specifically, the third reinforcing layer 6 can structurally enhance the compressive strength of the PP and PE mixed composite corrugated pipe.

[0031] The process of using this utility model is as follows: The operator first makes the core tube 1, then winds the first reinforcing layer 2 and fixes it with heat fusion, then winds the composite tube 3 and the second reinforcing layer 4, and then winds the outer layer of the corrugated composite layer 5 and fixes it with heat fusion to form the wound composite tube. Finally, the third reinforcing layer 6 is wound around the outer surface of the core tube 1 and fixed with heat fusion.
