湖杭铁路双层贝雷梁式墩梁支架施工应用技术

Construction and Application Technology of Double-layer Bailey Beam Pier Beam Support in Huhang Railway

随着我国铁路建设的快速发展,桥梁工程数量也是日益增多,尤其是城际铁路的快速发展跨越公路、管线也将日益增多。现浇连续梁墩梁式支架中双层贝雷梁的应运也就显得尤为重要,每一条上跨道路都有其独特的环境特征。墩梁式支架采用双层贝雷梁施工,安全、高效、节能。双层贝雷梁大跨度的跨越既有道路设施,解决了普通单层贝雷梁跨度小施工干扰大的难题。

With the rapid development of China's railway construction,the number of bridge projects is also increasing,especially the rapid development of intercity railways,crossing highways and pipelines will also increase.The application of the double-layer Beley beam in the cast-in-place continuous beam pier beam support is particularly important.Each upper-span road has its own unique environmental characteristics.The pier beam support adopts double-layer Bailey beam construction,which is safe,efficient and energy-saving.The large-span double-layer Bailey beam spans the existing road facilities,which solves the problem of large-span construction interference with the ordinary single-layer Bailey beam.
