Abstract

The invention relates to a suspension bridge main cable strand pre-forming and erection construction method. The method comprises a parallel steel wire rope strand, a steel wire, a front anchor cup, arear anchor cup, a positioning steel wire and a zinc-copper alloy block. The main cable strand preforming comprises the following steps of S1, manufacturing a marking steel wire; S2, manufacturing astandard length steel wire; S3, forming the parallel steel wire rope strand; and S4, pouring the steel wire rope strand anchor cup. The suspension bridge main cable strand pre-forming and erection construction method has a good structural stability, the two ends of a main cable strand are firmly connected with the front anchor cup and the rear anchor cup, the corrosion resistance is good, and theadvantages of protruding wires and scattered wires can be effectively eliminated.

Description

technical field [0001] The invention relates to the technical field of suspension bridge construction, in particular to a method for preforming and erecting main cable strands of a suspension bridge. Background technique [0002] Suspension bridges are bridges with tension-bearing cables or chain locks as the main load-bearing components. They are composed of suspension cables, cable towers, anchorages, suspenders, and deck systems. At present, the bridge with the largest span in the world is the suspension bridge with a span of 1991m built in 1998. Since the 1990s, the construction of suspension bridges in my country has entered a period of rapid development. As of 2013, my country has built 11 suspension bridges with a single span of more than 1,000 meters, marking that my country has entered the international advanced ranks in the field of suspension bridge construction. [0003] The main cable is the main load-bearing component of the suspension bridge. It mainly bears ...
