Column foot connecting method for additionally arranging sound barrier on existing rail transit bridge
The invention discloses a column base connecting method for additionally arranging a sound barrier on an existing rail transit bridge, which comprises the following steps of: arranging a fixing bolt between a U-shaped steel plate and a bridge baffle, arranging the U-shaped steel plate on the bridge baffle, and fastening a through bolt outside the U-shaped steel plate and the bridge baffle; the profile steel beam is arranged on the U-shaped steel plate, the fixing bolt penetrates through the lower side end face of the profile steel beam, and the fixing bolt is fastened; the steel stand columns are arranged on the profile steel cross beams, and the steel stand columns and the profile steel cross beams are fixedly connected through column foot bolts. The section steel cross beams are additionally arranged on the bridge baffles, the bridge baffles and the steel stand columns used for sound barrier installation are connected through the section steel cross beams, the problem that sound barrier column feet and existing bridge baffles cannot be directly connected is solved, transformation of existing bridges is avoided, the construction period is shortened, and normal operation of rail transit is guaranteed; the influence on the existing rail transit is small, the investment is saved, the economic and social benefits are objective, and the popularization and application prospects are good.
本发明公开了一种用于既有轨道交通桥梁增设声屏障的柱脚连接方法，包括以下步骤：将固定螺栓设置于U型钢板与桥梁挡板之间，并U型钢板置于桥梁挡板上，将对穿螺栓紧固于U型钢板、桥梁挡板外；将型钢横梁置于U型钢板上，且固定螺栓贯穿型钢横梁下侧端面，紧固固定螺栓；将钢立柱置于型钢横梁上，通过柱脚螺栓固定连接钢立柱、型钢横梁。利用在桥梁挡板上增设型钢横梁，通过型钢横梁分别连接桥梁挡板和声屏障安装所用的钢立柱，解决声屏障柱脚与既有桥梁挡板无法直接连接的困难，避免了对既有桥梁的改造，节约施工工期，保证轨道交通正常运营，对既有轨道交通影响小，节约了投资，具有客观的经济和社会效益，具备良好的推广应用前景。
