斜跨河流45 m现浇梁支架施工技术

On construction technique of 45-meter cast-in-place support across rivers

以和平站特大桥为例,通过选用321型贝雷梁作为主纵梁,配合5排螺旋管作为主支撑,跨河处采用型钢焊接为整体支架作为跨河支架的支撑结构,有效地解决了施工难题,为今后同类工程提供参考。

Taking the super-large bridge at Heping Station as the example,the paper selects type 321 bailey beam as the main longitudinal beam and 5-row spiral pipes as the main support,and adopts the steel welding general support as the support structure for the crossing-river support,so as to solve the construction difficulties and provide some reference for similar projects.
