运河上浮吊船整体架设钢桁梁施工技术

Construction Techniques for the Integral Erection of Steel Truss Beams with Floating Cranes on Canals

在运河上采用浮吊船整体架设钢桁梁,投入小、封航时间短、安全系数高。针对具体工程项目详细介绍了钢桁梁拼装的场地布置、基础、支架设计以及用浮吊船整体架设钢桁梁的施工工艺。钢桁梁架设顺利完成,相关经验可为类似施工提供借鉴。

The application of floating cranes to the integral erection of steel truss beams on canals helps to lower the cost-shortenthe route-closing tim e,and improve the security of construction. With real projects as exam ples, introduced in the paper arethe layout of the construction site the design of the foundation and the supporting scaffolds and the construction processes forthe integral erection of the steel truss beam with floating cranes on canals. T he successful completion of the integral erectionmay serve as a useful reference for other similar projects.
