Urban elevated bridge broken column jacking construction method and device
The invention belongs to the field of bridge construction, and provides an urban viaduct broken column jacking construction method and device, and the method comprises the following specific steps: S1, preparation work; s2, temporarily supporting and installing a jacking system; s3, the broken column is jacked; s4, pier column connection and bridge recovery; safety in the construction process can be ensured by forming a temporary support through the steel pipes connected into the lattice system, integrity of the beam body in the jacking process can be ensured by conducting overall proportional jacking through the pier position rotating point, and uneven deformation or stress concentration is avoided; the first joint, the second joint and the third joint are used for jacking the beam body to the designed gradient according to the overall proportion, it can be guaranteed that the beam body meets the preset gradient requirement in the jacking process, stable passing of the bridge and the stability of the structure are guaranteed, the jacking frequency and working procedures can be reduced by adopting overall proportion jacking and translation jacking, the construction efficiency is improved, and the construction period is shortened.
本发明属于桥梁施工领域，提供了一种城市高架桥梁断柱顶升施工方法及装置，具体步骤如下：S1：准备工作；S2：临时支撑并安装顶升系统；S3：断柱顶升；S4：墩柱连接及桥梁恢复；本发明通过连接为格构体系的钢管形成临时支撑可以确保施工过程中的安全性，通过以墩位旋转点进行整体比例顶升可以保证梁体顶升过程中保持整体性，避免出现不均匀变形或应力集中，通过第一联、第二联和第三联以整体比例顶升梁体至设计坡度，可以确保梁体在顶升过程中达到预定的坡度要求，保证桥梁的平稳通行和结构的稳定性，采用整体比例顶升和平移顶升可以减少顶升次数和工序，提高施工效率，缩短施工周期。
