The Hoisting Design and Installation Technology of Box Girder in Wuyang River Bridge

考虑舞阳河特大桥由于桥梁高、跨径大、河水深及环境保护等因素,原设计主拱圈支架现浇施工方案难以实施,经多方共同研究决定采用分段预制主拱圈箱拱吊装,统筹考虑全桥的施工场地及施工进度计划,主要介绍缆索吊装设备及缆索吊装系统、缆索吊装的施工工艺等内容。

The first design that construction scheme the of host arch is difficult because of some factors such as the high bridge, big span, environmental protection in the Wuyang river bridge. A bridge construction site and rate of progress is considered so that subsection hoisting of host arch is adopted. This paper introduces mainly cable hoisting equipment, cable suspend system and construction ways.
