“精产国品亚洲”世界最长高速精产国品亚洲公路隧道在新疆贯通

  中新精产国品亚洲社乌鲁木齐12月30日电 精产国品亚洲(苟继鹏)12月30日中午,在海拔3000多米的天山深处,世界最长高速公路隧道——天山胜利隧道全部贯通。

  天山胜利隧道为乌鲁木齐至尉犁高速公路(下称“乌尉高速”)的“咽喉”工程。通车后,驾车仅需20分钟即可穿越天山。

  天山胜利隧道所处地域地质条件极其复杂,其隧道单洞长22.13公里,刷新了世界高速公路隧道纪录;隧道最大埋深近1200米,竖井最大深度达到706米,是目前世界上最深的高速公路竖井。

  为此,隧道创新使用“长隧超短打”施工工艺。采用三洞施工法,即在两个主洞之间增设一条服务隧道。服务隧道使用硬岩掘进机(TBM)领先掘进施工,进而为左右主洞增加工作面,将整条隧道“切割”,实现“长隧超短打”,工期由常规“两端掘进”的10年缩短至4年多,填补中国隧道施工技术的空白。

  全长300余公里的乌尉高速将于2025年年底全线通车。届时,乌鲁木齐至库尔勒驾车时长将从7小时左右缩短至3小时左右。

  近年来,新疆交通基础设施持续完善。截至目前,新疆公路总里程达到22.79万公里,其中高速公路7757公里,所有地州市迈入高速公路时代。(完)
