Highway-railway interchange superstructure and engineering construction method
The invention relates to the technical field of overpass beam constructional engineering, in particular to a highway-railway overpass superstructure and an engineering construction method. Construction of a first span bridge deck system and a third span bridge deck system is completed on a construction site; through holes of the bridge girder erection machine, box girder erection, transverse partition plate welding connection, bridge deck steel plate laying, hogging moment tension grouting, wall collision prevention, net throwing prevention, bridge deck pavement, final completion acceptance, second-span girder erection through the bridge girder erection machine and one-time in-place installation are carried out, efficiency and safety performance are greatly improved, when the bridge girder erection machine passes through the holes, temporary rails do not need to be laid, and the construction cost is reduced. The rear support and the beam carrying flatcar share the track, the working intensity is reduced, and the bridge erecting machine can adapt to construction of different curved bridges, skew bridges and straight bridges and meet general construction conditions.
本发明涉及立交桥梁建筑工程技术领域，具体涉及一种公铁立交上部结构及工程施工方法，施工现场已完成第一、第三垮桥面系施工，然后进行第二跨支座安装，进行架桥机过孔、箱梁架设、横隔板焊联、桥面钢板铺设、负弯矩张拉压浆、防撞墙、防抛网、桥面铺装，最后竣工验收，利用架桥机进行第二跨架梁，一次性安装到位，大大提高了效率和安全性能，架桥机机过孔时，不需要铺设临时轨道，后支座与载梁平车共用轨道，降低了工作强度，并架桥机能适应不同曲桥、斜桥和直桥的施工，满足一般施工条件。
