上跨铁路既有线关键架梁技术探析

Key Beam Erecting Technology of the Existing Railway

结合某铁路桥跨既有线架梁施工,根据架桥机和梁板自重、架桥机架梁高程确定承重混凝土基础尺寸,并对架桥机过孔、梁板架设施工工艺及所需时间进行分析、总结规律,进一步规范架桥机上跨铁路施工程序。

Combined with the construction of a railway bridge across the existing line,the size of bearing concrete foundation is determined according to the self-weight of the bridge erecting machine and the beam slab and the elevation of the bridge erecting frame beam.Through the analysis of the construction technology and the time required for the bridge erecting machine moving through the hole and the beam slab erection,the construction procedure of the bridge erecting machine on the broken iron road is standardized.
