Steel box arch bridge single arch rib framing swivel system and construction method thereof
The invention belongs to the technical field of bridge construction, and relates to a steel box arch bridge single arch rib framing swivel system and a construction method thereof. The system comprises a lower rotary disc located on a foundation, a horizontal swivel system fixedly installed on the lower rotary disc, an upper rotary disc rotationally installed on the horizontal swivel system and atraction system detachably connected with the upper rotary disc; a vertical rotating system comprises a vertical rotating hinge installed on the inner side of the upper rotating disc and used for fixing an arch rib to be assembled, a buckle cable installed on the outer side of the upper rotating disc, a buckle tower installed on the upper rotating disc and a rear anchor system fixedly installed onthe outer side of the upper rotating disc and used for balancing the upper rotating disc. The buckle cable comprises a lower buckle cable connected between the upper rotary disc and the buckle towerand an upper buckle cable connected between the buckle tower and the free end of the arch rib to be assembled, a plurality of balance cables are installed between the inner side of the upper portion of the buckle tower and the outer side of the upper rotary disc, the construction method guarantees the construction quality of the arch bridge, safety risks are reduced, construction is convenient, and the construction cost is reduced.
本发明属于桥梁施工技术领域，涉及一种钢箱拱桥单拱肋分幅转体系统及其施工方法，平转体系包括坐落在地基上的下转盘、固定安装在下转盘上的平转系统、转动安装在平转系统上的上转盘以及与上转盘可拆卸连接的牵引系统；竖转体系包括安装在上转盘内侧且用于固定待拼装拱肋的竖转铰、安装在上转盘外侧的扣索、安装在上转盘上的扣塔以及固定安装在上转盘外侧用于平衡上转盘的后锚系统，扣索包括连接在上转盘和扣塔之间的下扣索和连接在扣塔和待拼装拱肋自由端的上扣索，扣塔上部内侧与上转盘外侧之间安装有若干根平衡索，该施工方法保障了拱桥的施工质量，降低了安全风险，且施工方便，降低了施工成本。
