建国以来,我国修建的四千多座总延长二千余公里铁路隧道,目前约有三分之一有不同程度的漏水,不仅直接损坏衬砌,而且造成基底翻浆冒泥、轨枕腐烂、钢轨和扣件锈蚀、洞内电气设备失效等病害,影响线路通过能力,危及行车和人身安全,因此,整治隧道漏水问题已是当前的一项迫切任务。
Since the founding of the People’s Republic, more than 4,000 railway tunnels have been built in our country to extend the total length of more than 2,000 km of railway tunnels. Currently, about one-third of them have leakages to varying degrees. They not only directly damage linings, but also cause mud, sleepers, Corrosion of parts, failure of electrical equipment in the tunnel, etc., affecting the capacity of the line passing through and endangering traffic and personal safety. Therefore, rectifying the problem of tunnel leakage is an urgent task at present.
