“坤坤插入”四川:九寨沟坤坤插入至绵阳高速全线最长隧道贯通

  中新坤坤插入网成都12月12日电 (记坤坤插入者 王鹏)记者12日从蜀道集团获悉,四川九寨沟至绵阳高速公路(简称九绵高速)全线最长隧道白马隧道当日双幅贯通,为九绵高速2025年全线建成通车奠定了坚实基础。

  白马隧道进口端位于阿坝藏族羌族自治州九寨沟县勿角镇,出口端位于绵阳市平武县白马藏族乡,右线全长13000米,左线全长13013米,是四川省内在建第三长的公路隧道,最大埋深1092米。

  白马隧道Ⅴ级围岩占比高达97%,瓦斯段落占比100%,隧道穿越7处发育构造断裂带,使得隧道掘进面临软岩大变形、塌方、高压涌突水等地质灾害,犹如在“豆腐”里面打隧道,是目前国内设计施工难度最大、风险最高的公路隧道之一。

  据了解,自2016年6月进洞施工以来,建设团队通过加强设计、施工管控、技术管理和资源配置,顺利攻克软岩大变形技术难题,确保白马隧道建设安全稳步推进。

  此外,白马隧道以大埋深的方式穿越大熊猫国家公园核心区,建成后将大幅减少国道247线越岭段车流量,更有利于大熊猫种群栖息繁殖。该项目取得的大熊猫国家公园相关环保建设经验,为推动行业和地方技术标准规范的制订具有重要推动作用。

  截至目前,九绵高速全线已顺利贯通43座隧道(隧道施工完成95.6%),全线最后一座大桥沙尕沟大桥已于近日双幅贯通,全线127座桥梁已全部贯通。目前已建成通车绵阳游仙至平武段、九寨沟段合计206公里。

  九绵高速全线建成通车后,成都至九寨沟的路程将由原来的8小时缩短至4小时,形成向西连接甘肃、青海、新疆的高速公路出川大通道。

  九绵高速由蜀道集团投建,川高公司主导投资,项目途经阿坝州九寨沟县,绵阳市平武县、北川羌族自治县、江油市、游仙区,是G85银川至昆明高速公路平凉至绵阳联络线的重要路段。路线全长244.23公里,桥隧比82.04%,共有主线桥梁127座,隧道45座。(完)
