[0024] The technical solutions in the embodiments of the present utility model will be described below with reference to the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the present utility model, not all of the embodiments. For the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without making creative inventions belong to the scope of protection of the present utility model.
[0025] As Figures 1-4 shown, a high-density polyethylene steel fiber wound high-strength and high-toughness composite pipe is formed by winding a strip body 1. The strip body 1 includes an inner wall 2 and an outer wall 3. A cavity 4 is provided between the inner wall 2 and the outer wall 3 of the strip body 1 along the length direction of the strip body 1. A reinforcing rib 5 is provided in the cavity 4 along the length direction, and a steel fiber belt 6 is provided in the strip body 1 along the length direction.
[0026] The strip body 1 is made of high-density polyethylene strip.
[0027] The steel fiber strip 6 is arranged at the bonding layer inside the inner wall 2 of the strip body 1.
[0028] Steel fiber strips 6 are provided at the bonding layers inside both the inner wall 2 and the outer wall 3 of the strip body 1.
[0029] A metal material strip 7 is arranged inside the reinforcing rib 5.
[0030] The outer wall of the strip body 1 is smooth.
[0031] The outer wall of the strip body 1 is corrugated.
[0032] The number of the steel fiber strips 6 is 1 - 10 layers according to the internal and external pressure strengths.
[0033] Example 1:
[0034] As Figure 5 shown, the outer wall of the strip body 1 is corrugated. Steel fiber strips 6 are provided at the bonding layers inside both the inner wall 2 and the outer wall 3 of the strip body 1, and a metal material strip 7 is arranged inside the reinforcing rib 5.
[0035] Example 2:
[0036] As Figure 6 shown, the outer wall of the strip body 1 is corrugated. The steel fiber strip 6 is arranged at the bonding layer inside the inner wall 2 of the strip body 1, and a metal material strip 7 is arranged inside the reinforcing rib 5.
[0037] Example 3:
[0038] As Figure 7 shown, the outer wall of the strip body 1 is smooth. Steel fiber strips 6 are provided at the bonding layers inside both the inner wall 2 and the outer wall 3 of the strip body 1, and a metal material strip 7 is arranged inside the reinforcing rib 5.
[0039] Example 4:
[0040] As Figure 8 shown, the outer wall of the strip body 1 is smooth. Steel fiber strips 6 are provided at the bonding layers inside both the inner wall and the outer wall of the strip body 1, and there is no metal material strip 7 inside the reinforcing rib 5.
[0041] Example 5:
