Large-span frame bridge jacking construction method for reinforcing existing railway lines based on combined temporary beams
The invention relates to the technical field of business line railway jacking construction, and particularly discloses a large-span frame bridge jacking construction method for reinforcing an existing railway line based on combined temporary beams. Comprising the steps of frame structure bridge prefabrication and back beam construction, rail stress relief, temporary buttress installation, steel sleeper beam installation, longitudinal beam installation, manual hole digging pile construction, transverse lifting beam installation, excavation and jacking, combined construction beam dismantling and line recovery. After the temporary buttresses are used for erecting the combined I-beam, operations such as manual hole pile digging and transverse lifting beam mounting can be carried out, the buckling rail beam pile digging process is omitted, the safety risk is reduced, and the construction period is shortened. When the manual hole digging pile is constructed, a construction channel is dug under a railway line, the number of times that personnel enter the railway line can be reduced, railway operation and personal safety are guaranteed, meanwhile, continuous construction can be conducted when a train comes, and construction efficiency is improved.
本发明涉及营业线铁路顶进施工技术领域，具体公开了基于组合工便梁加固既有铁路线进行大跨度框架桥顶进施工方法，包括框构桥预制及后背梁施工→轨道应力放散→临时支墩安装→钢枕梁安装→纵梁安装→人工挖孔桩施工→横抬梁安装→开挖顶进→组合工便梁拆除、线路恢复。利用临时支墩进行组合工便梁架设后，便可进行人工挖孔桩、横抬梁安装等作业，取消扣轨梁挖桩工艺，减少安全风险，节省工期。施工人工挖孔桩时，在铁路线路下开挖施工通道，可减少人员进入铁路线内的次数，保障了铁路运行及人身安全，同时列车来临时可连续施工，提高了施工效率。
