大跨度钢管混凝土提篮拱安装施工技术

On construction technique for basket handle arch installation of large-span concrete filled steel tube

结合某大跨度钢管混凝土提篮拱施工案例,从提篮拱安装方案、钢管拱肋吊装、拱肋侧转等方面对大跨度钢管混凝土提篮拱安装施工技术进行了分析与研究,通过实践证明,应用提篮拱安装施工技术,操作较为简单,应用于桥梁施工中综合效益明显。

Combining with the basket handle arch construction case for some large-spa concrete filed steel tube, the paper analyzes and researches the installation construction of the large-span concrete filled steel tube from the installation scheme for the basket handle arch, the lifting of the arch rib, and the rib side-tracking, and proves the practice that the installation construction technique of the basket handle arch is simple opera tion with obvious comprehensive benefits.
