永和大桥钢管拱肋节段吊装施工控制

Construction Controlling of Suspending Placement in Steel Tubular Arch Truss Articulations of Yonghe CFST Arch Bridge

结合南宁市永和大桥的施工过程,主要介绍了该次钢管拱肋吊装施工技术的要点。该次钢管拱肋吊装采用的一些关键性施工技术成功地解决了实际施工过程中的一系列难题,是对我国钢管混凝土拱桥的缆索吊机斜拉扣挂悬臂拼装施工方法的进一步完善,对今后同类桥梁的施工,具有很好的参考价值。

Yonghe CFST arch bridge locates in the outer ring road of Nanning city. The key technologies of steel tubular arch rib hoisting construction are expatiated in this paper. These technologies solved some knotty problem in construction and improve the non-support cable hoisting with cableway crane with cable-stayed cantilever construction technology of our country. These construction techniques provide some available references for the CFST arch bridge construction.
