Beam arch combined system bridge structure and jacking and rotating construction method
The invention belongs to the technical field of bridge building construction, and provides a beam-arch combined system bridge structure and a jacking and rotating construction method.The beam-arch combined system bridge structure comprises a bridge lower structure, a main beam, a bridge arch structure, an arch foot cross beam, a rotating device and a temporary lengthening cross beam; the main beam is connected with a bridge lower structure, the arch springing cross beam is arranged at the joint of the main beam and the bridge lower structure, the two ends of the arch springing cross beam extend out of the two sides of the main beam, and the temporary lengthening cross beam is detachably connected with the arch springing cross beam; the swivel device is in sliding fit with the temporary lengthened cross beam, and the bridge arch structure is detachably hinged to the swivel device. The structure and construction steps are reasonable in design, transverse rotation construction of the arch of the bridge arch structure can be completed when the bridge deck is narrow, and the method is convenient in step construction and has great application prospects.
本发明属于桥梁建筑施工技术领域，提供一种梁拱组合体系桥梁结构及顶升、转体施工方法，其中梁拱组合体系桥梁结构包括桥梁下部结构、主梁、桥梁拱结构、拱脚横梁、转体装置和临时接长横梁；主梁与桥梁下部结构连接，拱脚横梁设于主梁与桥梁下部结构的连接处，且拱脚横梁的两端从主梁的两侧伸出，临时接长横梁与拱脚横梁可拆卸式连接；转体装置与临时接长横梁滑动配合，桥梁拱结构与转体装置可拆卸式铰接连接。本申请的结构及施工步骤设计合理，能够使桥梁拱结构在桥面较窄时也能完成对拱的横向转体施工，且该方法步骤施工便捷，具有很大的应用前景。
