长大隧道内铺设的钢轨及配件,在地质水文复杂、通风排水设备不完善等条件下,通过水、烟、冰的共同作用,促使钢轨锈蚀,从而给设备的正常使用、维修以及安全运输工作带来一系列问题。因此,研究解决钢轨及其配件的腐蚀问题就显得非常重要。一、杜草隧道概况杜草隧道位于开道线杜草～治山两个车站之间,分为新旧两条,新隧道由1975年5月开始施工,1980年9月通车运营,全长3900.53米,进口(哈方)有487.68米,为450米半径曲
Under the conditions of complicated geological and hydrological conditions and imperfect ventilation and drainage facilities, the rails and accessories laid in the long tunnels promote the rail corrosion through the joint action of water, smoke and ice, thereby giving the normal use, maintenance and safe transportation of the equipment Brought a series of questions. Therefore, it is very important to study and solve the corrosion problem of rails and fittings. I. Introduction of Ducao Tunnel Ducao Tunnel is located between the two stations of Ducao-Zhiyan in the open road. It is divided into two old and new stations. The new tunnel started construction in May 1975 and opened to traffic in September 1980 with a total length of 3900.53 meters. Import (Kazakhstan) 487.68 meters, 450 meters radius of curvature
