Steel truss girder erection construction method
The invention belongs to the technical field of bridge construction, and provides a steel truss girder erection construction method which comprises the following steps: S1, guide beam and girder erection crane installation construction and S2, main body steel truss girder erection construction, and the guide beam and girder erection crane installation construction comprises steel guide beam installation, steel truss girder SA16/SA15/SA14 hoisting and girder erection crane installation; by adopting the combined erection construction method of side span pushing and main span cantilever hoisting, the problem that a support method and a single cantilever assembly method cannot meet the construction requirement is solved, the construction difficulty of large-section steel truss girder erection and the influence on navigation are reduced, the construction safety is ensured, and the construction efficiency is improved; and meanwhile, by adopting a tower beam parallel construction method, the construction period and benefits are guaranteed, and the method is suitable for large-scale popularization.
本发明属于桥梁建设技术领域，提供了一种钢桁梁架设施工方法，包括以下步骤：S1、导梁及架梁起重机安装施工和S2、主体钢桁梁架设施工，其中导梁及架梁起重机安装施工包括钢导梁安装和钢桁梁SA16/SA15/SA14吊装及架梁起重机安装；本发明通过采用边跨顶推+主跨悬臂吊装的组合架设施工方法，解决了支架法及单一悬臂拼装法不能满足施工的问题，降低了大节段钢桁梁架设的施工难度及对通航的影响，确保了施工安全，提高了施工效率；同时通过采用塔梁平行施工的方法，保证了施工工期及效益，适合大规模推广。
