Reinforced concrete deck type arch bridge and construction method thereof
The invention discloses a reinforced concrete deck-type arch bridge and a construction method thereof, and belongs to the technical field of deck-type arch bridge construction.The arch bridge comprises a main arch ring steel arch frame, the main arch ring steel arch frame is provided with a plurality of spandrel columns, a bridge deck system is arranged at the tops of the spandrel columns, and the two ends of the bridge deck system are each provided with a bridge abutment fixedly connected with a foundation; the two ends of the main arch ring steel arch frame are each provided with an arch support, the two arch supports are fixedly connected with a foundation, and each arch support is provided with a plurality of sand unloading cylinders. The two ends of the main arch ring steel arch frame are each provided with one end triangular section piece, the two end triangular section pieces are hinged to the multiple unloading sand cylinders, the main arch ring steel arch frame is divided into the middle arch crown closure section, the splicing section and the arch foot section, rapid splicing in a factory can be achieved, rapid splicing through a cable crane system on site is facilitated, the construction steps are simplified, and the construction efficiency is improved. The construction efficiency of the reinforced concrete deck type arch bridge is improved, and the construction period of the reinforced concrete deck type arch bridge is shortened.
本发明公开了一种钢筋混凝土上承式拱桥及其施工方法，属于上承式拱桥施工技术领域，该拱桥包括主拱圈钢拱架，主拱圈钢拱架设有多根拱上立柱，多根拱上立柱的顶部设置有桥面系，桥面系的两端均设置有一个与地基固定连接的桥台；主拱圈钢拱架的两端端部均设置有一个拱座，两个拱座均与地基固定连接，每个拱座上均设置有多个卸载砂筒；主拱圈钢拱架的两端分别设置有一个端三角节件，两个分别与多个卸载砂筒铰接，通过将主拱圈钢拱架分割为中间拱顶合拢段节、拼接段和拱脚段，不仅可以实现在工厂快速拼接，而且便于现场使用缆索吊系统快速拼装，简化了施工步骤，加快了钢筋混凝土上承式拱桥施工效率，缩短了钢筋混凝土上承式拱桥施工周期。
