Precise assembly construction structure of large-span stiff skeleton concrete arch bridge
The invention discloses a precise assembly construction structure of a large-span stiff skeleton concrete arch bridge, and belongs to the technical field of bridge construction. The precise assembly construction structure comprises a mountain body, arch feet, arch rings, tower frames, a connecting steel cable, hanging rods, bridge columns and a road surface, wherein the tower frames are arranged at the top of the mountain body; the connecting steel cable is used for connecting the two tower frames; and the hanging rods are arranged at the bottom of the connecting steel cable. According to theprecise assembly construction structure, the arch rings of the concrete arch bridge are composed of the two fixed arch rings and one connecting arch ring, so that the length of each independent half arch ring is shortened, the transportation difficulty, the requirements for equipment and the construction difficulty are reduced, the construction period can be shortened, and the construction processis simplified; according to the invention, the tower frames can be used as cableway brackets for mounting the semi-arch ring when the arch bridge is constructed, and can also be used as bridge towerframes after the construction is finished; and the bridge columns and the arch rings are dragged by utilizing the connecting steel ropes and the hanging rods, so that the effect of sharing the supporting force is achieved, and the stability of the bridge is improved.
本发明公开了一种大跨劲性骨架混凝土拱桥精准拼装施工结构，属于桥梁建筑技术领域，包括山体、拱脚、拱圈、塔架、连接钢索、吊杆、桥柱和路面，所述塔架设置于山体的顶部；所述连接钢索用于连接两个塔架；所述吊杆设置于连接钢索的底部。本发明中，该混凝土拱桥的拱圈采用两个固定拱圈和一个连接拱圈组成，缩短了每个单独的半拱圈的长度，降低了运输困难、对设备的要求以及施工难度，还可以缩短工期，简化施工工艺；本发明中，塔架在对拱桥施工时可以充当安装半拱圈用的索道支架，在施工结束后还可以充当桥梁塔架，利用连接钢索和吊杆对桥柱以及拱圈进行牵引，起到分担支撑力的作用，提高桥梁的稳定性。
