双壁钢围堰因其整体刚度大、结构稳定性强,在大型深水承台施工中往往作为首选围水结构,适用范围较广。双壁钢围堰发展至今,设计、施工技术均已成熟,但襄阳汉江五桥主墩围堰需克服深水、深埋两大难题。本文则正是以汉江五桥主墩围堰设计与施工为依托,解决卵石层中深水深埋围堰的设计与施工技术难题,为以后相似工程提供参考借鉴。 Due to its large overall rigidity and strong structural stability, double-wall steel cofferdam is often used as the preferred surrounding water structure in the construction of large-scale deep-water cap-bearing platforms and has a wide scope of application. Since the development of double-walled steel cofferdam, design and construction technology have matured. However, two main problems of deep-water and deep-buried cofferdam of Xiangyang Hanjiang River Fifth Bridge are to be overcome. Based on the design and construction of the main pier cofferdam of the fifth Hanjiang River Bridge, this paper solves the design and construction technical problems of deep cofferdam in pebble bed and provides reference for similar projects in the future.
