摘要
该文结合上海某跨江大桥的钢桁梁实际施工情况,阐述和分析了钢桁梁整节段全焊拼装作为一种比较先进的施工工艺在实际施工中的应用。整节段全焊拼装技术与传统的单杆件散拼法相比,减少了高空作业量,实现了工地作业工厂化、高空作业地面化、水上作业陆地化、散装作业整体化的目标,大幅缩短了工期,提高了钢桁梁的安装质量,具有较高的经济效益。
According to the practical construction condition of steel truss beam for a crossing-river bridge in Shanghai, the article sets forth and analyzes the full-welding assembly of integrated segment for the steel truss beam taken as a more advanced construction technology to be applied in the practical construction. Compared with the traditional single-member assembly method, the full-welding assembly technique of integrated segment decreases the overhead working quantity, realizes the objective of field working to factory, overhear working to ground, water working to land and single-assembly working to integration, which widely shorten the constructing period, enhance the installing quality of steel truss, and have the higher economical benefits.
