青龙湾大桥海上拼装式整体下放大型双壁钢吊箱施工技术

Construction of Large Double Wall Steel Hanging Box with Integral Assembling Method for Qinglong Bay Bridge at Sea

跨海大桥的施工面临多变的气象环境、复杂的海底地质与水文条件等众多不利因素,迄今为止,没有任何2座大桥采用完全相同的施工技术。青龙湾跨海大桥通过多方面比选,水中承台施工采用双壁钢吊箱围堰法施工,钢结构加工厂分块预制,海上整体拼装,减少了施工空间,保护了自然环境。

Changeable weather environment,complex seabed geological and hydrological conditions of the impact of many unfavorable factors faced by the construction of sea-crossing bridge,so far,no any two bridges use exactly the same bridge construction technology. Through schemes selection from several aspects for Qinglong Bay Bridge,the construction measures of the project in the construction of double wall steel hanging box cofferdam construction,steel structure processing plant block and the whole assembly reduced the construction space and protect the natural environment.
