青岛海湾大桥是国家高速公路网青岛到兰州高速公路的起点段,是山东省“五纵四横一环”公路网上框架的重要组成部分,是青岛市规划的胶州湾东西两岸跨海通道“一路、一桥、一隧”中的“一桥”。上部结构形式主要是现浇箱梁、预制箱梁吊装、大节段钢箱梁吊装。针对移动模架现浇箱梁大桥各参建设方充分论证施工方案,制定了详细的施工措施,决定在十合同段做现浇箱梁的首孔浇筑;本文介绍了现浇箱梁的施工工艺、预应力施工、试验参数、质量检验、施工总结等内容,为以后的现浇箱梁施工提供施工经验。
Qingdao Bay Bridge is the starting point of National Expressway Network Qingdao to Lanzhou Expressway and an important part of Shandong Province’s “Five Vertical, Four Horizontal and One Ring” highway network framework. Qingdao Bay Bridge is a planned cross-sea channel between east and west of Jiaozhou Bay “All the way, a bridge, a tunnel” in the “bridge.” The superstructures are mainly cast-in-place box girder, prefabricated box girder hoisting, large section steel box girder hoisting. In order to fully demonstrate the construction plan for all the construction sites of cast-in-place box girder bridge with movable floor frame, detailed construction measures are formulated and the first hole of cast-in-place box girder is decided to be cast in the same ten sections. The construction technology of cast- , Prestressed construction, test parameters, quality inspection, construction summary and so on, providing construction experience for the construction of cast-in-place box girder in the future.
