Plan Selection of Steel Overhead Bin Lowering

襄渝铁路二线流水河右线大桥位于陕西省安康市火石岩水库内,主墩基础入水深度达60 m,采用直径为2.0 m的钻孔灌注桩基础,承台为深水高桩承台,采用单壁钢吊箱围堰施工。结合工程建设实例对单壁钢吊箱的下放方案的选定进行了探讨。

Yijia River Right-strung Large Bridge and Liushui River Right-strung Large Bridge of Xiangyu Ⅱ strung railway are located in the reservoir of Ankang City. The water entry depth of its main pier foundations is 60 m, which adopt the boring cast-in-place foundation with a diameter of 2.0 m. The pile caps are elevated in deep water and adopt the single-wall steel overhead bin-cofferdam construction. In light of the construction practice, this paper discusses the plan selection of single-wall steel overhead bin＇ s lowering.
