摘要
本文通过重庆轨道交通三号线菜园坝长江大桥段钢轨道梁裂纹病害处理施工实例,论述利用加固、钻孔止裂、焊接修补的方法对钢轨道梁裂纹进行处理,实现在轨道线路正常运营下,人员仅携带便携式工具处理裂纹的工作方式,可降低维修成本,延长钢轨道梁使用寿命。
Through the construction example of rail track girder crack treatment in the Caiyuanba Yangtze River Bridge section of Chongqing Rail Transit Line 3,this paper discusses the treatment of cracks in rail track girder by means of reinforcement,drilling and crack relief,welding and repair methods,so as to realize the working method of treating cracks by personnel with portable tools only under the normal operation of the track line,which can reduce maintenance costs and prolong the service life of rail track girder.
