摘要
详细阐述了汉十铁路大跨度钢管混凝土提篮式系杆拱桥拱脚的施工工艺和关键技术操作要点,借助拱脚定位装置、钢管拱定位坐标的计算软件以及BIM技术,保证了大桥拱肋线形的精确和拱脚施工的质量。
The construction process and key technical operation points of the arch foot of the long-span concrete filled steel tube basket tied arch bridge in the Han–Shi railway are elaborated. With the help of the positioning device for arch foot, the calculation software for positioning coordinates of the steel tube arch and the BIM technology, the accuracy of the line shape of bridge arch rib and the construction quality of arch foot are guaranteed.
