预应力混凝土连续梁节段预制拼装已成为当今桥梁建设的发展方向,预制、拼装可平行作业,工厂化、机械化施工质量更有保证,对环境影响小,施工周期短、效率高。武西高速公路桃花峪黄河大桥引桥连续箱梁,就是采用先简支后连续节段预制拼装施工。文章介绍了桃花峪黄河大桥引桥箱梁节段拼装施工及工艺,通过优化设备选型、优选胶拼材料、工艺的实施实现节段拼装优质快速施工。
The prefabricated prefabricated prefabricated continuous beams of prestressed concrete have become the development direction of bridge construction. Prefabrication and assembly can be carried out in parallel. The quality of mechanized construction can be guaranteed with little impact on the environment, short construction period and high efficiency. Wusi Expressway Taohuayu Yellow River Bridge continuous box girder, is the use of the first simple support after the continuous prefabricated segment assembly construction. This paper introduces the assembly and construction of the bridge girder section of the Taohuayu Yellow River Bridge, optimizes the equipment selection, optimizes the selection of materials and processes, and achieves the high quality and speedy construction of segment assembly.
