北街水道桥异形索塔爬架设计

The climbing frame design of north channel bridge special-shaped cable bent tower

以广中江高速公路北街水道桥工程为例,设计了一套适应索塔异形截面的爬架体系,介绍了该爬架系统的结构组成要素,并阐述了爬架施工工艺流程,解决了异形截面索塔变化多、施工难的问题。

Taking the north channel bridge engineering in Guangzhongjiang Expressway as an example, this paper designed a climbing frame systemadapt to cable bent tower special-shaped section, introduced the structure elements of climbing frame system, and elaborated the climbingframe construction process, solved the problems of profiled cable bent tower more changes, difficult construction.
