摘要
文章以常益长铁路某特大桥工程为依托,着重对其中的门式墩钢盖梁施工技术的应用要点展开探讨,具体包括钢盖梁的现场焊接、螺栓连接、运输、拼装、吊装等方面,研究成果可为类似跨线铁路门式墩钢盖梁施工提供技术参考。
Based on a super-large bridge project on Changde-Yiyang-Changsha railway,this paper focuses on the application points of the steel cover beam construction technology for portal piers,including on-site welding,bolt connection,transportation,assembly and hoisting of the steel cover beam.The research results can provide technical reference for the construction of the steel cover beam for portal piers of similar cross-line railways.
