摘要
江阴新沟河大桥主桥加劲梁采用五跨连续预应力钢筋混凝土结构,施工时采用以梁柱式临时支架为主的支撑系统和分段分次现浇混凝土施工技术,解决了全桥自重和施工荷载在主缆和吊索张拉调整结束、完成桥梁体系转换之前一直需要进行支撑以及现浇加劲梁大体积混凝土一次性浇筑量大、水化热高的技术难题。
The stiffened girder of main bridge in Jiangyin Xingou river bridge is five-span continuous prestressed reinforced concrete structure. The temporary support system with beams and columns and pouring concrete in some times are adopted to resolve that the supports are needed to bear the bridge weight and construction load,the technique difficulties of large concrete pouring volume in one time and the high hydration heat are solved too.
