依托迁曹铁路曹妃甸特大桥预留二线架梁工程,针对4.0 m小线间距架设T梁,临近既有电气化铁路,接触网不停电、铁路不停运架梁的实际情况,就如何确保安全运梁、喂梁、架梁,研究采用架桥机改造,接触网改造,架桥机立柱采取绝缘措施,偏移铺设工程线,偏位架梁,激光测距控制等措施,达到了临近既有电气化铁路小间距预留二线安全架梁、快速架梁的目的。
Relying on Cao Cao Caofeidian Bridge to reserve second-line beam girder project, for the 4.0 m small line spacing erection of T-beam, near the existing electrified railway, the contact line without electricity, the railway non-stop transporting the actual situation of the beam, on how to ensure safe transportation Beam, girder, girder, the research adopts bridge machine transformation, catenary reconstruction, erecting machine girders to take insulation measures, offset laying project line, deflection beam, laser ranging control and other measures, reaching the existing Small railway electric railway reserved for second-line safety girder, the purpose of fast girder.
