铆接钢桁梁桥整体修复关键施工技术

Key Construction Technology for Overall Repair of Riveted Truss Girder Bridge

阐述了铆接钢桁梁桥的应用现状及修复原则,以浙江路桥为例,分析制定了铆接钢桁梁整体修复的方案,重点对铆接桥梁修复过程中的杆件拆换、主桁片顶推横移、钢桁梁维修、线形控制、铆钉更换及铆接施工等关键技术进行了介绍,可为同类桥梁的修复提供借鉴。

The application status and repair principle of the riveted truss girder bridge are elaborated. Taking Zhejiang road bridge as an example, the scheme for the overall repair of the riveted truss girder is analyzed, and key technologies like member bar replacement, pushing and transverse movement of main truss unit, steel truss girder maintenance, linear control, rivet replacement and riveted construction and so on during the maintenance of riveted truss girder bridge are introduced emphatically, so as to provide reference for the repair of similar bridge .
