向阳河中桥维修加固及拓宽改造施工技术

Construction Technology of Maintenance and Reinforcement and Widening and Reconstruction of Xiangyang River Middle Bridge

针对向阳河中桥在建成多年后,由于原有道路等级提升,需要对该桥进行维修加固以及拓宽改造这一问题,对该桥梁进行实地调研,详细了解向阳河中桥的整体工程概况以及病害分布情况。通过对向阳河中桥的病害分析,制定了裂缝注浆封闭以及粘贴钢板加固两种措施,并对该桥的加固设计方案以及施工要点进行详细分析,完成了加固改造拓宽任务。

Aiming at the problem that Xiangyang River middle bridge needs to be repaired,strengthened,widened and reconstructed due to the upgrade of the original road level after many years of completion,the method of on-site investigation of the bridge is used to learn more about the overall project overview of the bridge and Disease distribution.Through the analysis of the disease of Xiangyang River middle bridge,two methods including crack grouting sealing method and pasting steel plate reinforcement are formulated,and the reinforcement design scheme and construction key points of the bridge are analyzed in detail,and the task of reinforcement,reconstruction and widening was completed.
