摘要
介绍江西省温 (家圳 )厚 (田 )高速公路龙王庙赣江大桥水中高桩承台的施工 ,针对深水急流施工条件 ,采用单壁钢吊箱围堰技术。阐述了设计思路、结构形式和施工技术 ,并对承台施工进行了详细叙述。施工承台封底混凝土时使用了水下不离散混凝土絮凝剂UWB ,保证了施工质量。该项技术较好地解决了施工中的难题 ,其成功经验对今后类似工程的施工具有参考。
The paper introduces the underwater construction of elevated pile foundation of Gan River Bridge. According to the deepwater construction conditions the technology of single wall steel suspending cofferdam is adopted. In this paper the think of design, form of structure and the construction technology are elaborated and the construction of elevated pile foundation is stated in detail. The bottoming concrete in foundation construction uses non discrete concrete flocculation agent UWB to ensure the construction quality. This technology solves the problems in construction and has referenced and generalized value for the same project in future.
