随着我国经济的不断发展,桥梁施工技术水平也进一步提升。但在桥梁工程的水中承台施工中,由于地质水文条件和周边环境复杂、施工难度较大、安全风险较高等诸多不利因素,选用水中围堰的类型将对于施工安全、工程质量和施工成本将产生较大影响。本文对钢筋混凝土围堰和双壁钢围堰组合式围堰在白沙河大桥主墩承台施工中的应用情况进行了详细介绍,为在桥梁施工中使用组合围堰提供参考。 With the continuous development of economy in our country, the technical level of bridge construction has been further improved. However, due to many unfavorable factors, such as geological and hydrological conditions and surrounding environment, difficulty in construction and high safety risk, the type of cofferdam used in water supply for bridge construction will be of great significance to the construction safety, construction quality and construction cost Have a greater impact. In this paper, the application of combined cofferdam reinforced concrete cofferdam and double-walled steel cofferdam in the construction of the main pier foundation of Baishahe Bridge was introduced in detail in this paper to provide references for the use of combined cofferdam in bridge construction.
