Novel cantilever construction steel box arch bridge structure without temporary measures
The invention discloses a novel cantilever construction steel box arch bridge structure without temporary measures. The structure is formed by combining a steel box arch rib, a concrete skewback, a plurality of suspenders and a bridge deck structure. By increasing the cross section size of the arch rib and depending on self structure cantilever construction, the arch rib can bear the structure stress in a finished bridge state and can meet the stress requirements of various working conditions in the construction stage; jacking force can be applied to the two sides of the arch rib before the arch rib is closed, the stress of the arch rib and the arch support is adjusted, and the purpose of saving the construction cost is achieved; in the construction process of the arch ribs, closure and arch forming of the arch ribs can be achieved without the help of external auxiliary facilities, a large number of temporary measures needed in the previous arch bridge arch rib construction process are saved, the arch bridge manufacturing cost is reduced, and the safety reserve of the arch bridge is improved.
本发明公开了一种无大临措施新型悬臂施工的钢箱拱桥结构，结构由钢箱拱肋、混凝土拱座、若干吊杆以及桥面结构组合而成；本发明通过增加拱肋截面尺寸，依靠自身结构悬臂施工，使其不仅可以承受成桥状态下的结构受力，还能满足施工阶段各工况受力需求；在拱肋合龙前也可对拱肋向两侧施加顶推力，调整拱肋、拱座的受力，达到节约工程造价的目的；拱肋在施工过程中不需要借助外部辅助设施即可实现拱肋合龙成拱，节约了以往拱桥拱肋施工过程中所需的大量临时措施，降低了拱桥造价、提高了拱桥的安全储备。
