营业线箱梁横移改线综合施工技术研究及应用

Research and Application of Comprehensive Construction Technology for Transverse Shift and Change of Business Line Box Girder

宁盐上、下行联络线与连镇铁路同步实施,新建宁淮铁路引入相关工程需对已建宁盐上、下行联络线部分线路进行优化,由于既有宁盐铁路上、下行线特大桥已完成铺轨架梁工作,通过对既有宁盐铁路既有箱梁采用梁位纵横向调整、高差调整、角度分级偏转、滑靴滑道组合滑移系统等关键技术的应用,实现了对既有箱梁的利旧,为后续类似工程的施工提供借鉴及参考。

Ningyan upper and lower link lines are implemented simultaneously with Lianzhen Railway. The introduction of related projects for the new Ningyan and Huai Railway needs to optimize some lines of the existing upper and lower link lines of Ningyan Railway. Since the existing super bridge of the upper and lower lines of Ningyan Railway has completed the work of laying rails and setting beams, Through the application of key technologies such as beam position adjustment, height difference adjustment, angle grade deflection, slipboot slide combination sliding system and so on to the existing box girder of Ningyan Railway, the existing box girder is restored, which provides reference for the subsequent construction of similar projects.
