松花江公铁两用桥96＋2×144＋96 m钢桁梁架设施工技术

摘要

针对滨北线松花江公铁两用桥96＋2×144＋96 m 钢桁梁架设，介绍采用散拼杆件，悬臂拼装的施工方法，以及通过对临时墩和墩顶纵横移设备的合理设计与施工，顺利实现合龙，从而取得了良好的经济效益。%Aiming at the 96 +2 ×144 +96 m steel truss girder erection of Songhua River Highway and Railway Combined Bridge in the Harbin-Beian Railway,this paper introduces the smooth realization of closure achieved by adopting the con-struction method of cantilever assembly with scattered levers,as well as the rational design and construction of temporary pier and vertical and horizontal moving equipment at the top of the pier,which has achieved good economic benefits.
