Synchronous jacking reverse slope adjusting, splicing and widening system for hollow slab bridge and construction method
The invention relates to a hollow slab bridge synchronous jacking reverse slope adjusting, splicing and widening system and a construction method. The hollow slab bridge synchronous jacking reverse slope adjusting, splicing and widening system comprises pier columns, prefabricated hollow slabs, cover beams, pier and abutment support synchronous jacking systems, non-dismantling steel jacket box concrete heightened cushion stones and beam bottom synchronous grading jacking pre-arching systems. The beam bottom synchronous grading jacking pre-arching system comprises a sliding rail and a steel pipe support, the steel pipe support slides on the sliding rail, a jack is arranged at the top of the steel pipe support, and the jack is supported below the center line of the single prefabricated hollow slab. The method has the beneficial effects that synchronous jacking reverse slope adjustment of the hollow slab bridge is achieved through the pier and abutment support synchronous jacking system, and the construction efficiency of synchronous jacking reverse slope adjustment, splicing and widening of the hollow slab bridge is greatly improved; and the bottom of the center line of the hollow slab is jacked through the beam bottom synchronous grading jacking pre-arch system.
本发明涉及一种空心板桥同步顶升反坡调整拼接拓宽体系及施工方法，包括：墩柱、预制空心板、盖梁、墩台支架同步顶升体系、免拆钢套箱混凝土加高垫石和梁底同步分级顶升预拱体系；梁底同步分级顶升预拱体系包括滑轨和钢管支撑，钢管支撑在滑轨上滑动，钢管支撑顶部设有千斤顶，顶撑在单个预制空心板的中线下方。本发明的有益效果是：通过墩台支架同步顶升体系实现空心板桥同步顶升反坡调整，大幅度提高了空心板桥同步顶升反坡调整拼接拓宽施工效率；通过梁底同步分级顶升预拱体系对空心板中心线底部进行顶升。
