摘    要:介绍某(114.75+229.5+114.75)m钢桁柔性拱钢桥的架设方法与配套施工装备设计。该钢桥共有两座,一座主跨跨越高速公路,另一座主跨跨越河流。跨越高速公路者不允许在桥下设置临时支墩或进行吊装作业,跨越河流者在桥下设置临时支墩既困难也不经济。所以提出采用专门的塔吊提升站+架梁动臂吊机进行对称悬臂拼装架设方案。阐述了架设方案设计及配套施工装备设计,尤其是架梁动臂吊机的设计要则。

关 键 词:钢桁柔性拱  配套施工装备  架梁动臂吊机  塔吊提升站

Abstract:This paper introduces the laying and erecting method and complement construction equipment design of a (114.75 + 229.5 + 114.75) m steel truss flexible arch beam bridge.There are two bridges of this kind,the main span of one crossing a highway,and the main span of another crossing a river.Setting temporary rest pier or doing lifting works under bridges is not allowed for those crossing highways;its hard and costly to set up temporary rest pier under bridge for those crossing rivers.Therefore,a symmetrical c...
Keywords:steel truss flexible arch beam  complement construction equipment  movable arm tower crane for erecting bridges  lifting station of tower crane
