摘要： Provided is a method for manufacturing a hot extruded polyethylene zinc-aluminium alloy-plated steel wire hauling cable. The method involves: in accordance with arrangement rules for steel wires at the cross section of a hauling cable (4), the length of the hauling cable is controlled through a central standard wire, zinc-aluminium alloy-plated steel wires are bundled at a twisting angle of 2°-4°, a high-strength polyester belt is wound externally on the steel wire bundle, a double-layer high-density polyethylene protection layer is hot-extruded through a double-cavity co-extrusion one-time moulding process, anti-wind- and rain-induced vibration embossments are arranged on the outer layer of a polyethylene protection jacket according to design requirements of the hauling cable (4) regarding wind- and rain-induced vibration, and the hauling cable is coiled and stored after both ends of the hauling cable (4) are anchored. Finally, the hauling cable is transported to an erection site according to delivery requirements, and erected one by one. The process for manufacturing the hauling cable (4) is not limited by a construction site, is less affected by climate factors, is convenient to control due to industrialised production management, and can satisfy the service requirements of long length, high accuracy, and durability for stay cables in super -long-span bridges in a marine environment.

摘要： A method for manufacturing prefabricated parallel steel wire preformed cable strands for a main cable of a suspension bridge, comprising: prefabricating a plurality of zinc-coated steel wires into cable strands in factory, wherein this step mainly comprises the fabrication and configuration of marked steel wires and standard steel wires and a steel wire placement and shaping procedure; preforming desired cross sections at positions of the cable strands corresponding to tower and splay saddles, in order to install the cable strands to the saddles. Both ends of each cable strand are anchored using hot-cast anchors, and then the cable strands are coiled and transported to the construction site, and then are mounted one by one. Due to high precision during fabrication, the cable strands have stable quality and can be quickly mounted.
