Stone arch bridge structure transformed by stacked concrete rigid framework and transformation method
The invention discloses a stone arch bridge structure transformed by a stacked concrete rigid framework and a transformation method, the stone arch bridge structure comprises a stone main arch and an arch bridge pier platform used for supporting the stone main arch, a stacked concrete main beam is poured on an arch building of the stone arch bridge, and a stacked concrete pier platform used for supporting the stacked concrete main beam is poured on the arch bridge pier platform; according to the construction method, the arch bridge pier platform and the stone main arch of the original stone arch bridge are utilized, the overlapped concrete main beam and the concrete bridge piers are directly poured, the existing stone arch bridge is not reinforced, only an arch building of the stone arch bridge is used as a template support of the newly-built reinforced concrete continuous rigid frame bridge for construction, and the later vehicle load is borne by the overlapped reinforced concrete continuous rigid frame bridge; under the conditions that the shape of the original stone arch bridge is not changed and the stone arch bridge is not reinforced and maintained, the bearing capacity of the bridge can be improved to an expected degree, the uncertainty of reinforcing the stone arch bridge and the safety risk of dismantling are avoided, a large amount of waste is not required to be treated, the technical implementation and the construction quality are easy to guarantee, and remarkable technical, economic and social benefits are achieved.
本发明公开了一种叠建砼刚构改造的石拱桥构造及改造方法，括石砌主拱和用于支撑石砌主拱的拱桥墩台，在石拱桥的拱上建筑上浇筑叠建砼主梁，在拱桥墩台上浇筑用于支撑叠建砼主梁的叠建砼墩台；本发明利用原石拱桥的拱桥墩台以及石砌主拱，直接浇筑叠建砼主梁以及砼桥墩，不加固既有石拱桥，施工仅以石拱桥的拱上建筑作为新建钢筋混凝土连续刚构桥的模板支承，后期车辆荷载由叠建钢筋混凝土连续刚构桥承受，在不改变原石拱桥外形并不对石拱桥本身加固维修的条件下，可将桥梁的承载能力提升至期望程度，避免了石拱桥加固的不确定性及拆除安全风险，且无需大量废方处理，技术实施以及施工质量容易保障，具有显著的技术、经济和社会效益。
