摘要
针对过隧道型架桥机在20‰下坡架设900 t预制箱梁的特殊工况,依据铁路桥梁架设规范和过隧道型架桥机结构性能的特点,确定了顺坡过孔、平坡架梁的架设作业原则,采用了垫墩调整提梁机、下导梁高度的施工工艺,具有一定的参考价值。
The response of bridge-tunnel in the 20‰ downhill erecting prefabricated box girder 900 tons of the special status, based on the railway bridge erection norms and the bridge-tunnel-type structure of the characteristics identified longitudinal the hole, the slope-beam erection operating principles, use pad adjustment pier crane machines, the high-bean： construction process. It has the reference east.
