Assembling construction method for arch ribs in through basket steel box tied arch bridge
The invention provides an assembling construction method of an arch rib in a through basket steel box tied arch bridge, which comprises the construction steps of construction of a bridge floor structure, construction of an arch rib bracket, prefabrication and transportation of the arch rib, hoisting of the arch rib, hoisting of a wind brace, removal of a vertical bracket, reservation of an inclined bracket and the like. The inclined support and the vertical support are combined, the characteristic of good economical efficiency of the vertical support and the advantage of high safety of the inclined support are combined together, the bridge deck is prevented from being stressed, the buckling problem of the bridge deck is fundamentally solved, and meanwhile the stability of the support meets the construction requirement. After the arch ribs are assembled, only the vertical supports in the arch rib supports are removed, the inclined supports are reserved, and during pushing construction, the inclined supports serve as temporary supporting rods of the arch ribs, so that the structural strength is ensured to meet the construction requirements, materials are saved, and the construction cost is reduced.
本发明提供了一种下承式提篮钢箱系杆拱桥中拱肋的拼装施工方法，包括桥面结构的施工、拱肋支架搭建、拱肋预制和运输、拱肋吊装、风撑吊装和拆除直立支架保留斜支架等施工步骤，本发明中拱肋的拼装施工方法，将斜支架与直立支架进行组合，将直立支架经济性好的特点与斜立支架安全性高的优势结合在一起，避免桥面板受力，从根本上解决桥面板屈曲问题，同时支架稳定性也满足施工要求；而拱肋拼装完成后，只拆除拱肋支架中的直立支架而保留斜支架，在顶推施工时，斜支架作为拱肋临时撑杆，不仅保证了结构强度满足施工要求同时节约了材料，降低了施工成本。
