Construction method of steel box girder mounting system of large-span steel box tied arch bridge
The invention relates to a construction method of a steel box girder mounting system of a large-span steel box tied arch bridge. According to the scheme, the construction method comprises the steps that S00, a concrete enlarged foundation is poured; s10, a steel box girder support is erected; s20, an anti-collision pile is driven; s30, bearing platform end cross beams are installed; s40, mounting the steel box girder; s50, side box girders are hoisted; s60, mounting a steel cross beam; the numerical control hydraulic jacks are arranged on the rear portion of the main bridge bearing platform, the steel box girders and the steel cross beams are jacked up by the upper portions of the numerical control hydraulic jacks, and the steel box girders and the steel cross beams at the ends are made to fall on the main bridge bearing platform by operating the numerical control hydraulic jacks. Various convenient construction structures can be provided, and the construction efficiency is improved.
本申请涉及大跨径钢箱系杆拱桥钢箱梁安装体系施工方法，该方案包括S00、混凝土扩大基础浇筑；S10、钢箱梁支架搭设；S20、防撞桩打设；S30、承台端横梁安装；S40、钢箱梁安装；S50、边箱梁吊装；S60、钢横梁安装；S70、整体落梁：将数控液压千斤顶置于主桥承台后部，上部顶起钢箱梁和钢横梁，通过操作数控液压千斤顶使得端部钢箱梁和钢横梁落在主桥承台上。本申请可提供多种便捷施工结构，加快施工效率。
