11月4日，记者从渝黔铁路有限公司获悉，渝湘高铁重庆至黔江段低瓦斯长隧道陈家院子隧道顺利贯通，为全线如期建成通车奠定了坚实基础。
陈家院子隧道位于重庆市武隆区，为双线单洞隧道，全长3440米，最大埋深327米。隧区穿越煤线地层，瓦斯区段占比83%，Ⅳ、Ⅴ级围岩占比89%，坍塌、瓦斯爆炸安全风险极高，施工安全压力大，给施工建设带来极大挑战。
渝湘高铁重庆至黔江段是国家中长期铁路网规划“八纵八横”中厦渝通道的重要组成部分，从重庆站引出，途经渝中、南岸、巴南、南川、武隆、彭水等区县，止于重庆市黔江区，设计时速350公里。与黔张常铁路、常益长铁路连接，线路连接长江中游城市群，是成渝城市群、长江中游城市群、海西城市群间高速客运交流的通道。
