跨海大桥40m跨度上行式移动模架施工探讨

Discussion on Construction of Upward Moving Formwork for the 40-meter Span of Sea-crossing Bridge

移动模架法是铁路简支箱梁原位造桥施工的一种重要方法。福厦铁路湄洲湾跨海大桥312号墩~341号台,此段落介于斜拉桥与隧道之间,根据地形地势及墩身高度等参数综合比选,采用上行式移动模架,主梁在待制箱梁上方,借助已完成箱梁和桥墩移位造梁。

The mobile formwork method is an important method for in-situ bridge construction of railway simply supported box girder.Pier No.312 to Platform No.341 of Meizhou Bay Cross-sea Bridge of Fuxia Railway,this section is between the cablestayed bridge and the tunnel.It is comprehensively selected according to the topography and pier height and other parameters.The upward mobile formwork is adopted.The girder is above the box girder to be manufactured,and the girder is constructed by shifting the completed box girder and bridge piers.
