央广网北京6月20日消息(记者孟永辉王妍)据中国之声《新闻和报纸摘要》报道,昨天上午,随着全线卡脖子工程胡麻岭隧道贯通,连接我国西南和西北最便捷的铁路大通道——兰渝铁路全线贯通。
胡麻岭隧道是连接我国西北和西南最便捷快速的大能力运输通道——兰渝高速路上的“头号重难点工程”。2011年8月,离贯通仅剩173米时,施工遇到了“第三系富水粉细砂”地层。
中铁第一勘察设计院院长刘为民:胡麻岭隧道地层的水稳特性非常复杂,在施工的过程中,不断出现突水、流沙等现象。
在这样的地层做隧道开凿就好比在“在豆腐脑里打洞”。过去5年半,胡麻岭隧道发生了四次大突涌,清理砂浆15万立方米,2015年,建设者研发出组合式的真空降水技术,使开凿速度大大加快。
胡麻岭隧道的正式贯通,意味着兰渝铁路将于今年年内全线开通运营,服务甘陕川渝三省一市的22个县区。建成通车后,重庆直达兰州全程运行距离比现在可缩短近700公里,节省运行时间约11个小时。
