铁路隧道里的坚守：高温天穿秋裤，日行万步护通行安全|182tv免费视频在线观看
中新网牡丹江7月17日电 (席凯)“外面30多摄氏度，进隧道得先套秋裤。”这是国铁哈尔滨局集团公司牡丹江工务段牡丹江路桥车间工长唐衍海说得最多的一句话。
7月16日8时许，唐衍海和3名伙伴拿着检查工具，走向滨绥铁路最老的咽喉——杜草隧道。这条1942年建成的隧道全长7773.5米。
隧道分为上下行，唐衍海一般早上出发，检查完往哈尔滨方向的上行隧道，下午紧接着再检查往牡丹江方向的下行隧道，这样一去一回，每天一趟。
“我们不是散步，是‘看病’。”唐衍海把隧道当成一位老人，“钢轨是骨头，衬砌是皮肤，渗水、裂纹就是老年斑，得天天看。”夏天，隧道里仅有20摄氏度左右，冷风顺着钢轨灌进来，像开了最大挡的空调。可这份“凉爽”并不友好。
“外面一身汗，进去三分钟就起鸡皮疙瘩，冷热一激，感冒来的可勤呢。”57岁的桥隧工苏友明边说边裹紧工装外套，裤脚里还露出一截秋裤。更难受的是潮湿，不到半小时，衣服黏在身上，像裹了一层保鲜膜。
一去一回就是一万五千多米，巡检的时候需要慢走细看，内侧壁、拱腰及拱顶都要认真仔细地检查，他们弯腰看路基、抬头看拱顶、侧耳听滴水。“最怕听见‘滴答’。”“渗水一多，冬天结冰就容易把衬砌撑裂，易造成安全隐患。”唐衍海说。
11时许，上行隧道检查完，4个人蹲在隧道口吃起了自己带的食物。随便对付一口他们就继续检查，回程时太阳正毒，隧道口的光像一道白帘子，把里外隔成两个世界。
15时，唐衍海和工友们走出隧道，衣服上的水珠被太阳蒸成盐渍。“今天微信运动又第一。”桥隧工贾志信晃了晃手机。(完)
