Embodiment 1
[0053] Embodiment 1: A durable cable body made of a single-layer PE cable body wound with a spiral rib tape.
[0054] Such as Figure 1-1~Figure 1-2 As shown, the durable cable body of the wound spiral rib tape includes a steel wire bundle 1, a winding tape 2 and a high-density polyethylene sheath 3, and after the steel wire bundle 1 is wrapped into a bundle by the winding tape 2, the high-density polyethylene Ethylene forms a high-density polyethylene sheath 3, and outside the high-density polyethylene sheath 3 one A spiral-rib adhesive tape 5 laminated by spiral winding; the surface of the spiral-rib adhesive tape 5 has two parallel ribs 501 .
Embodiment 2
[0055] Embodiment 2: a durable cable body with double-layer PE cable body wound with spiral rib tape.
[0056] Such as Figure 2-1~Figure 2-2 As shown, the durable cable body of the double-layer PE cable body wrapped with a spiral rib tape includes a steel wire bundle 1, a winding tape 2 and a high-density polyethylene sheath, and the steel wire bundle 1 is wrapped into a bundle by the winding tape 2 , heat-extruded high-density polyethylene to form an inner layer of high-density polyethylene sheath 3, and then heat-extruded high-density polyethylene to form an outer layer of high-density polyethylene sheath 4 outside the inner layer of high-density polyethylene sheath 3, There is a layer of spiral rib tape 5 attached by spiral winding outside the outer high-density polyethylene sheath 4; the surface of the spiral rib tape 5 has two raised parallel ribs 501.
[0057] In embodiment one and embodiment two, described spiral rib adhesive tape 5 can be single-layer spiral rib adhe...
Embodiment 3
[0062] Embodiment three: a method for manufacturing a durable cable body wound with a spiral rib tape, there are two methods for making the cable body:
[0063] The first method is: the durable cable body wrapped with spiral rib tape is completed in the cable body manufacturer. Density polyethylene sheath, and then a layer of lap-joint spiral rib tape is pasted on the outside of the high-density polyethylene sheath of the cable body by spiral winding. The lap-joint spiral rib tape includes a lap-joint single-layer spiral rib Adhesive tape 51a is either pasted or calendered a layer of protective film on the lap-joint single-layer spiral-rib adhesive tape 51a or a lap-joint composite spiral-rib adhesive tape 53a formed by spraying or brushing a layer of protective layer 52 .
[0064] The second method is: the durable cable body wrapped with spiral rib tape is completed at the construction site;
[0065] The specific method is: first wrap the steel wire bundles of the cable stay...
