摘要
该文以泉州湾跨海大桥南岸深水区引桥施工为依托,从钢吊箱的设计和施工工艺两方面,介绍了装配式钢吊箱在高桩承台施工中的应用。钢吊箱围堰施工具有施工工期短,水流阻力小、利于通航、不需要沉入河床、施工难度小、混凝土用量小等特点,目前在大跨深水桥梁中得到了广泛的应用。
Depending on the construction of the approach bridge in Quanzhou Bay Crossing-sea Bridge South Bank Deepwater Zone,the article introduces the application of assembled steel hanging box in the construction of high-pile base slab from two aspects of the design and construction of steel hanging box.The cofferdam construction of steel hanging box has been widely applied in the construction of long-span deepwater bridges because of its characteristics of the short construction period,small flow resistance,being convenient for shipping,not necessary to submerge to the riverbed,small construction difficulty and small concrete usage.
