宁夏境内第一条高铁隧道——银西高铁惠安堡隧道贯通

2017-09-20 18:42:08   央广网

央广网盐池920日消息(记者徐升)今天上午,我国“八纵八横”高速铁路网的重要组成部分——银西高铁惠安堡隧道顺利贯通。标志着宁夏境内高铁隧道实现“零”的突破。

惠安堡隧道由中铁上海工程局承建,隧道在宁夏回族自治区吴忠市盐池县惠安堡镇宋儿庄煤矿矿区内,距离国道211线约300米惠安堡是宁夏境内第一高铁隧道,也是银西高铁全线第一条贯通的隧道。隧道全长756米,地质复杂,不良地质和特殊地段多,地质灾害风险大。属于标段重点控制性工程,它的贯通,有利于推动银西高铁建设进度。

施工现场

据了解,银西高铁是国家中长期铁路网规划八纵中的一纵,位于陕西、甘肃及宁夏三省区境内,连接关天经济区、陇东地区和沿黄城市带,行经整个黄土高原。线路南起西北地区中心城市西安,经陕西省咸阳市、甘肃省庆阳市、宁夏吴忠市后接入银川市,全线共设车站20处。是串联陕甘宁革命老区的首条高铁,是推动“一带一路”的快速通道。对于密切少数民族地区与内地人员往来和经贸交流,促进区域经济社会发展和民生改善具有重要意义。

隧道内部

根据计划,银西高铁将于2020年底全线通车,届时宁夏融入国家高速铁路网。乘火车从西安到银川将由现在的14小时车程缩短至3小时左右
