路桥工程中危桥加固施工与维修技术研究

Research on Construction and Maintenance Technology of Reinforcement of Dangerous Bridge in Road and Bridge Engineering

本文针对锚喷混凝土加固技术、增大梁截面加固法、体外预应力加固技术进行了基本介绍,以某危桥加固维修项目为实例,围绕裂缝修补、粘贴钢板、增大截面加固、桥梁维修四个层面,探讨了危桥加固施工与维修技术在路桥工程中的具体应用,以期为危桥加固工程施工管理提供参考依据。

This article gives a basic introduction to the reinforcement technology of anchor shotcrete,the reinforcement method of enlarged beam section and the external prestressed reinforcement technology.Taking a dangerous bridge reinforcement and repair project as an example,it discusses the specific application of the construction and maintenance technology of dangerous bridges in road and bridge engineering around the crack repair,paste steel plates,increase of the cross-section reinforcement and bridge maintenance four levels,with a view to providing reference for the construction management of the reinforcement engineering of dangerous bridges.
