邻近营业线跨繁忙航道大跨度钢桁梁无导梁纵移及横移施工技术

Non-guided Beam Longitudinal and Transverse Construction Technology of Large-span Steel Truss Beam across Busy Waterway adjacent to Business Lines

主要介绍新建沪通铁路跨蕴藻浜128m钢桁梁,邻近既有沪宁线跨蕴藻浜航道进行钢桁梁无导梁纵移及横移施工,对钢桁架施工支架搭设、钢桁梁拼装、无导梁纵移及横移就位施工工艺、施工的难点及安全注意事项等方面进行了详细的阐述,为类似工程施工提供一定参考。

This paper mainly introduces non-guided beam longitudinal and transverse construction of 128m steel truss beam across Yunzaobang in Shanghai-Nantong railway,which is adjacent to the existing Shanghai-Nanjing railway line,and describes the construction technology,construction difficulties and safety precautions of steel truss construction support,steel truss beam assembly,non-guided beam longitudinal and transverse position in detail,which provides a certain reference for similar engineering construction.
