中新网贵阳11月22日电 (记者 瞿宏伦)一列黄色大型养路机械车组22日在贵州省毕节市境内的成贵高铁高坡隧道内精准启动轨道作业，标志着成贵高铁首次大型清筛施工正式拉开序幕。
2019年12月16日，成贵高铁正式投入运营。该线路作为“八纵八横”高速铁路网兰州(西宁)至广州通道的重要组成部分，自西南向东北方向，与渝贵高铁、贵广高铁等多条线路相接，连接了成都、贵阳两大西南客运中心，打通了从成都平原经四川盆地，穿越云贵高原至珠江三角洲、长江三角洲等地的快速铁路通道，形成了一条串连中国西部与华南、华东、东南沿海地区的战略要道，将贵州丰富的资源与广阔的市场紧密相连，为贵州的经济增长和社会进步注入了强大的动能。
成贵高铁全线共有隧道183座、桥梁468座，全线桥隧比高达81.5%，是一条名副其实的“云上高铁”。为保证线路运行安全，中国铁路成都局集团有限公司统筹全局资源，成立技术协调、质量监管、应急保障等多个专业组，有序推进施工作业。施工前，组织宜宾工电段深入隧道内部，全面掌握隧道结构、空气条件、线路状态等基础情况。各专业组据此制定“一隧道一方案”施工策略。
每日线路列车停运后，组织成都工务大机段调集桥隧清筛车、捣固车等18台大型养路机械设备，完成对轨道的道砟更换、线路捣固等作业，并在次日首班动车开行前完成线路检测，避免了对日间动车组正常运行的影响。
此次清筛施工预计12月底全面完工，将为成贵高铁提供更加安全平稳高效的通行条件，将进一步推动区域经济一体化进程，为西部地区的产业结构调整、新型城镇化建设、民众生活水平提升提供强大的推动力。(完)
