Concrete-filled steel tube arch bridge
The invention is applicable to the technical field of bridges, and provides a concrete-filled steel tube arch bridge which comprises an arch rib, a bridge floor structure fixed on the arch rib and an arch foot seat. The arch ribs are used for bearing a bridge deck structure and comprise a first main arch rib, a second main arch rib and a transverse supporting structure, the first main arch rib and the second main arch rib are arranged in parallel in the width direction of a bridge deck and are each of an arch structure, and the transverse supporting structure is fixedly connected between the first main arch rib and the second main arch rib; the arch foot seats are used for supporting the arch ribs and arranged at the two ends of the first main arch rib and the two ends of the second main arch rib respectively, each arch foot seat comprises an arch seat body and an arch foot arranged on the arch seat body, and the arch feet are used for connecting the arch ribs with the arch foot seats. According to the scheme, the arch bridge is divided into the arch rib, the bridge deck structure and the arch foot base, the arch rib and the arch foot base can be manufactured in advance and then transported to a construction site to connect the arch rib with the arch foot on the arch foot base, then the bridge deck structure is laid, the construction process is simplified, and manpower and material resources are saved.
本发明适用于桥梁技术领域，提供了一种混凝土拱桥，钢管混凝土拱桥包括拱肋、固定在拱肋上的桥面结构以及拱脚座；拱肋用于承载桥面结构，拱肋包括第一主拱肋、第二主拱肋以及横撑结构，第一主拱肋和第二主拱肋沿桥面宽度方向平行设置且均为拱形结构，横撑结构固定连接在第一主拱肋和第二主拱肋之间；拱脚座用于支撑拱肋，拱脚座分别设置在第一主拱肋和第二主拱肋的两端，拱脚座包括拱座以及设置在拱座上的拱脚，拱脚用于将拱肋与拱脚座连接。本方案通过将拱桥分为拱肋、桥面结构以及拱脚座三个模块，拱肋和拱脚座可以提前制作完成然后运输到施工现场将拱肋与拱脚座上的拱脚连接，再铺设桥面结构，简化施工工艺，节省人力物力。
