900t小曲线半径(900m)箱梁架设施工工艺探讨

Discussion on construction technology of box beam erection of 900 tons small curve radius(900 m)

研究900 t箱梁在900 m半径上的架设工艺,结合沪昆客专湖南段国内首次900 m小曲线900 t箱梁架设采用空间转向和变频驱动,实现架桥机的小曲线架梁的成功经验,总结得出了900 m小曲线900 t箱梁架设施工工艺。

This paper analyzed the erecting technology of 900 tons box girder in 900 m radius,combining with the Shanghai-Kunming passenger railway Hu＇nan section used space special and variable frequency drive for the first time in 900 m small curve 900 tons box beam erection,realized the successful experience of small curve girder for bridging machine,concluded the construction technology of 900 m small curve 900 tons box beam.
