摘要
结合达成铁路客运专线32 m整孔箱梁架设的施工,总结了DF900D型导梁式定点起吊架桥机架设整孔箱梁施工工艺,并提出了安全质量控制措施,为以后的整孔箱梁、大吨位桥梁架设提供了施工技术指导。
As the construction of the passenger dedicated line started in an all-round way in China, the construction technology of 900 t whole-span box girder erection has been widely used. In this paper, with the construction technology of 32 m whole-span box girder erection in Dacheng Passenger Railway, we summarize the erecting construction technology of the whole-span box girder by DF900D fixed-point lifting bridge erection machine, and put forward the safety and quality control measures, to provide technical guidance for the erection of the whole-span box girder or large-tonnage bridge in the future.
