成都地铁隧道里的“轨道医生”
2017-08-22 17:36:33 中国青年网

8月22日凌晨,夜深人静,大多数民众已进入梦乡,但在成都升仙湖地铁站,一群身穿橘红色衣服的人,手拿工具推着手推车,进入地铁线路隧道内,开始了一天忙碌的工作,市民称他们为地铁线上的“轨道医生”。
地铁检修和巡查大多是在地铁线路半夜收车与凌晨发车之间进行,时间从凌晨零时至4时之间。“在密集的列车冲击下,钢轨会发生一些细微变化,夜间需对轨道进行一次健康‘体检’,发现问题快速处理,避免影响地铁安全运营。”61岁的范云贵称,每天的工作就是检查轨道、测量和调整轨距、为轨道更换胶垫等,消除和更换可能有安全隐患的构件或钢轨。
行走在隧道里,因相对封闭隧道内的温度有点高,穿着反光衣和戴着安全帽的记者与工人师傅一起由地铁升仙湖站往火车北站区间行进,工人师傅们边走边打着手电仔细照钢轨,有时会蹲下做标记。
行进中,巡道工人边走边对发现的问题做记号,后面检修的工人就会立即检修或更换铁轨垫板,同时对轨距进行测量,确保更换前后的铁轨距离可控。“这样,乘客乘坐地铁时就不会感到颠簸或晃动了。”范云贵称。
据悉,一年365天,只要地铁运行不停,这些“轨道医生”们的工作就永远不会停歇下来,冰冷的铁轨也就成为了他们唯一的“患者”。 刘忠俊 摄
