摘要
广州地铁四号线某墩节段箱梁胶拼施工时节段底板拼接缝不密贴,形成缝隙延伸至腹板中部,宽度逐渐减小并消失,但形成结构缺陷,文中以该梁拼装接缝处理施工实践为背景,介绍混凝土施工缝隙修补方法,为今后类似缺陷处理提供经验。
In the process of box girder splicing construction of Guangzhou Metro underground 4th line,some segments appeared cracks for splice joints not close,which extended from the base plates to the central webs with its width decrease gradually and disappeared,and caused structural defects.The article introduces the method on concrete construction crack repairing based on the splice joint processing construction practice of the bridge,and it provides reference experience for similar engineering construction for the future.
