箱梁后张法预应力施工质量控制要点

On quality control points of box girder post-tension method prestressed construction

就当前现浇式预应力钢筋混凝土箱梁施工中施工质量控制进行了阐述,结合箱梁施工工艺流程,详细介绍了箱梁模板施工,钢筋制作与安装,混凝土灌注,管道压浆等关键工序的质量控制要点,希望能为今后建设同类桥梁提供实际施工依据。

The paper illustrates the construction quality control in the current cast-in-situ prestressed reinforced concrete box girder, introduces the key procedures of the quality control factors, including the box girder model construction, the manufacture and installation of reinforcement, the concrete grouting and pipe grouting by combining with the construction craft procedure of the box girder, so as to provide the construction reference for similar bridge construction in future.
