Construction method of high-speed railway bridge catenary foundation
The invention discloses a construction method of a high-speed railway bridge catenary foundation, and relates to the field of high-speed railway bridge catenary foundation construction, which mainly aims to solve the problem of large construction difficulty when a bridge is supplemented with a catenary foundation in the prior art. Holes are formed in the bolt positions of a flange plate of a bridge body; bolts penetrate upwards from the bottom of the flange plate of the bridge body, and a lower embedded steel plate and an upper embedded steel plate are installed at the same time; the concretesurface chiseling treatment is performed within the top foundation range of the flange plate of the bridge body and the lower edge foundation of the flange plate, then drilling is performed, and steelbars are implanted after the holes are cleaned; residual structural steel bars are bound or welded; firm welding is performed after the steel bars are implanted; and a foundation formwork is installed, and concrete is poured. The foundation formwork at the lower edge of the flange plate is fixed through a scaffold, and a concrete mold inlet is reserved during installation. Concrete of a foundation base at the lower edge of the flange plate is vibrated by an attached vibrator, and the top foundation of the flange plate is vibrated by an inserted vibrating rod. The construction method has the advantage that the problems of misburying, missing burying and supplementing of the high-speed railway bridge catenary foundation are solved.
一种高速铁路桥梁接触网基础施工方法涉及高速铁路桥梁接触网基础施工领域。主要是为解决目前桥梁段补做接触网基础施工难度大的问题而发明的。在梁体翼缘板的螺栓位置开孔；自梁体翼缘板底部向上穿入螺栓，同时安装下预埋钢板和上预埋钢板；对梁体翼缘板顶基础范围及翼缘板下缘基础范围进行混凝土表面凿毛处理，然后钻孔，清孔后植入钢筋；绑扎或焊接剩余结构钢筋；植筋完毕后焊接牢固。安装基础模板，浇筑混凝土。翼缘板下缘基础模板通过脚手架固定，安装时，应留设混凝土入模口。翼缘板下缘基础底座混凝土采用附着式振捣器振捣，翼缘板顶面基础采用插入式振捣棒振捣。优点是解决了高速铁路桥梁接触网基础错埋、漏埋、补增问题。
