Lingdingyang Bridge of Shenzhong Link is a three-span suspension bridge with a full floating system of 580 + 1666 + 580. In view of the complex construction conditions of the bridge site, the construction scheme of island cofferdam was proposed for the east anchorage, and the flexible combined island cofferdam structure of ' lock steel pipe pile + I-shaped sheet pile + parallel steel wire rope ' was innovatively adopted to transform the offshore construction into land construction. For the east cable tower, the flexible manufacturing production line of steel mesh was developed, and the integrated intelligent tower building equipment suitable for ultra-high concrete cable tower was developed, forming the industrial construction technology of ultra-high cable tower based on reinforced bar product and intelligent tower building. The key construction technology of anchorage and tower solves the construction problem of super long-span suspension bridge in offshore sea, and improves the intelligent and industrial construction level of ultra-high tower engineering. |
