Construction method of large-span steel box continuous arch bridge
The invention discloses a construction method of a large-span steel box continuous arch bridge. The construction method comprises seven steps of dividing large sections of steel box girders, arranging shortcuts and gantry cranes, arranging a steel trestle, erecting a bracket, assembling the steel box girders, mounting other hole span steel girders and dismounting the bracket. According to the steel box girder, large-section splicing, flat car transportation and gantry crane hoisting are completed in a splicing field, the welding work amount of field installation is reduced, the project quality is guaranteed, before installation construction, through the BIM virtual installation technology, the problems occurring in the installation process of the large sections of the steel bridge are found out, an optimal correction scheme is given, and the construction efficiency is improved. Field work is reduced, and construction quality is improved.
本发明公开了大跨度钢箱连拱桥施工方法，包括钢箱梁大节段划分、便道及龙门吊布置、钢栈桥布置、支架搭设、钢箱梁拼装、安装其他孔跨钢梁和支架拆除七个步骤。本发明钢箱梁采用在拼装场完成大节段拼装，平板车运输，龙门吊吊装大节段箱梁，减少了现场安装的焊接工程量，有利于保证工程质量，在安装施工前通过BIM虚拟安装技术，找出钢桥梁大节段在安装过程中出现的问题并给出最佳修正方案，减少现场工作，提高施工质量。
