摘要： A method for fabricating a wire strand from parallel steel wires for a main cable of a suspension bridge, the method including: 1) selecting and coloring a steel wire as a marking steel wire which is to be positioned at a vertex of a wire strand including a plurality of parallel steel wires and having an equilateral polygon section; 2) drawing position markers at positions of the standard steel wire corresponding to control points of splay cable saddles, center points of main cable saddles, middle points of side spans, a middle point of a middle span, and starting points of anchor heads of anchor spans of a suspension bridge; 3) relaxing and shaping coils of the steel wires to yield a prefabricated wire strand; 4) preforming the positions of the cable saddles; 5) coiling the wire strand including; and 6) casting anchor of the wire strand.

摘要： A method for fabricating a steel wire cable having a Zn—Al alloy plating, the method including: arranging steel wires according to an arrangement rule at a cross section of the steel wire cable; controlling a length of the overall cable by a length of a central standard wire; twisting a bunch of the steel wires comprising a zinc-aluminum alloy plating with a torsion angle of between 2° and 4°; wrapping the steel wire bunch with a polyester wrapping bandage and covering a resulting product with a double-layered protective polyethylene sheath; anchoring the two ends of the steel wire cable by anchors using fillers; and coiling the finished-product of the steel wire cables.
