Composite protective layer corrosion resistant cable for cable-stayed bridge and steel wire preparation method
The invention relates to a composite protective layer corrosion resistant cable for a cable-stayed bridge. The composite protective layer corrosion resistant cable is prepared from the following steps: tightly arranging a plurality of steel wires into a steel wire bundle in a hexagon-shaped manner; continuously winding polyester fiber bands on the outer edge of the steel wire bundle, and arranging a polyethylene protective sleeve outside; stripping an epoxy resin coating on the outer layers of the steel wires, stretching into an anchor cup, of the cable; filling the space between the inner cavity of the anchor cup and the steel wire bundle with epoxy resin filler, so as to form a cool cast anchor, or filling the space between the inner cavity of the anchor cup and the steel wire bundle with a zinc-copper alloy, so as to form a hot cast anchor, wherein the steel wires are bright steel wires comprising cores; the outer layers of the bright steel wires are sequentially coated with a zinc aluminum plating and an epoxy resin coating. According to the invention, the zinc aluminum plating and the epoxy resin coating are sequentially arranged on the surfaces of the steel wires forming the cable from inside to outside, so that the anti-corrosion life can reach 100 years or above, and the corrosion resistance of the cable is improved. The invention also provides a steel wire preparation method with a simple technology.
