前坪水库交通桥施工中贝雷架支撑现浇连续箱梁技术的应用

Application of cast-in-place continuous box girder supported by Beret frame in traffic bridge of Qianping Reservoir

前坪水库输水洞交通桥施工采用贝雷架连续梁支撑顶模板方法进行,不受下部地形和地质条件影响,安全风险低、造价相对低廉。简述了贝雷架梁支撑方法、注意事项以及拆除过程,为类似工程提供借鉴和参考。

In the construction of the water transport tunnel bridge in Qianping Reservoir,the roof formwork supported by the continuous beam of Beret is adopted.This method is not affected by the lower terrain and geology,so it has low safety risk and relatively low cost.In this paper,the methods,precautions and removal process of Beret girders are briefly introduced to provide reference for similar projects.
