某大道跨陇海铁路转体桥施工技术探讨

On construction technique for rotary bridge crossing Lianyungang-Lanzhou Railway on some avenue

以某大道跨陇海铁路立交转体桥为背景,从公跨铁转体桥承台基础防护、下上承台施工、牵引索安装及保护、球铰加工、主墩施工、牵引系统、辅助系统、称重试验和配重、转体前准备工作、转体合拢实施6个方面系统的阐述了公跨铁转体桥梁施工各个环节施工工艺和要求,通过精心组织和严格的过程管理,顺利实现了某大道跨陇海铁路公跨铁转体桥顺利转体合拢。

Taking the rotary bridge crossing Lianyungang-Lanzhou Railway on some avenue as the background,the paper illustrates the construction crafts and requirements for every step for the rotary bridges for roads crossing railways from the six aspects,including the protection of the foundation platform of the rotary bridges for roads crossing railways,the construction of upper foundation,installation and protection of haulage cable,spherical hinge processing,construction of main pier,haulage system,auxiliary system,weight test and balance weight,preparations before the rotatory work,and the closure of the rotary structure,and realizes the rotary closure of the rotary bridge of roads crossing Lianyungang-Lanzhou Railway of some avenue with the cautious organization and process management.
