摘要
结合张石高速公路四十里峪大桥无落地支架现浇箱梁施工,利用墩柱抱箍和施工完的盖梁作为支点拼装贝雷梁作为支架进行现浇箱梁施工,取得了成功。重点介绍了现浇箱梁施工过程中的关键技术和控制要点,为同类施工提供参考。
Combined with experiences of construction technique for the non-floor stand cast-in-place box beam of Sishiliyu great bridge in Zhangshi elevated highway, cast-in-situ box girder is constructed by using the pier construction of hoop and the completed capping beam as fulcrum and assembling bailey beam as bracket. This paper mainly introduces the key technology and the control points of cast-in-situ box girder in the process of construction, which has a certain reference value for similar works.
