贵阳市水环境科普馆人行桥钢桁架拖拉施工技术

Construction technology of steel truss pulling of pedestrian bridge in Guiyang water environment science museum

以贵阳市水环境科普馆人行桥钢桁架工程施工为例,结合现场重点介绍在南明河打围堰,采用了钢管墩支撑+贝雷片+拖拉小车体系,及"分片吊装焊接成单个大节段+单个大节段钢桁架组装拖拉依次拖拉+整体落梁"的施工技术。

Taking for example the construction of steel truss of pedestrian bridge in Guiyang Water Environment Science Popularization Museum,the cofferdam construction technology in Nanming river is introduced emphatically combining with the site.The system of steel pipe pier support + Bailey piece + hauling cars is adopted,as well as the ' single large segment hoisted and welded + single large segment steel truss assembly and hauling + whole beam falling' construction technology.
