摘要
新建通辽至京沈高铁新民北站铁路跨越既有铁路运营线京通左线,中桥主跨采用1孔32m槽型梁,桥址位于通霍线与京通左线2线间通霍线路基上,紧邻通霍铁路。结合工程实际,对槽型梁梁体预制及质量控制、吊装方法及相关技术措施应用、吊装过程中梁体保护等方面进行阐述分析。
Newly built Tongliao to Beijing-Shenyang High-speed railway Xinmin north railway station crosses the existing railway operation line Beijing-Tongliao left line.The main span of the middle bridge adopts 1 hole 32 m groove beam,which is adjacent to the Tongliao-huolinhe Railway.Combined with engineering practice,the beam prefabrication and quality control,hoisting method and technical measures,beam protection and other aspects are analyzed.
