百米级预制装配式架设装备施工关键技术

Key construction technology of 100-meter prefabricated bridge erection equipment

文中以某跨海大桥为依托,针对海上预制装配化桥梁建设对施工场地和环境的高要求,提出了一种百米跨架设技术,研究设计了百米级海上预制装配式节段拼装架桥机。该技术采用节段拼装的施工工艺,实现了百米级跨径的架设技术,提高了施工效率,满足大跨度桥梁工程的特殊需求,为海上桥梁的建设提供了可行的解决方案。

Taking a sea-crossing bridge as an example,considering the demanding requirements for offshore prefabricated bridge construction on the construction site and environment,a 100-meter-span erection technology is proposed,and a 100-meter offshore prefabricated segmental bridge erection machine was studied and designed.The bridge erection machine adopts segmental assembly technology in the erection of 100-meter span,improves the construction efficiency,meets the special needs of long-span bridge engineering,and provides a feasible solution for the construction of offshore bridges.
