Construction Technology of Open Curved Steel Cable Tower for Chongzuo Bridge

崇左大桥敞开式曲线钢索塔结构特殊,施工中如何保证敞开式曲线钢索塔线形定位精准,对施工工艺和质量标准提出了较为苛刻的要求。崇左大桥钢索塔采用竖向分体制作运输,桥位吊装就位后焊接成型的施工工艺,较好地解决了索塔运输、吊装和安装精度的技术难题,确保了工程质量。

The structure of the open curved steel tower of Chongzuo Bridge is very special. How to ensure the alignment accuracy of the open curved steel cable tower is very strict, which requires more stringent requirements for construction technology and quality standard. Some technologies are adopted to build the steel cable tower of Chongzuo Bridge, such as the vertical parts manufacture and transportation, and hoisting these parts at bridge position and welding them to a whole. The technical difficulties of steel cable tower transportation, hoisting and installation accuracy are well solved, and the quality of the project is ensured.
