中国后生报客户端讯(丁玲 李金燕 中青报•中青网记者 宋宝颖)7月6日,集宁至通辽铁路电气化改动工程全线临了一座纯正——经棚纯正全隧获胜收尾意会,至此集通铁路电气化改动工程7座纯正一说念意会。
经棚纯正位于内蒙古赤峰市经棚镇境内,全长1450米,其中有935米处于风积沙地段,属于高风险纯正,施工难度极大,是全线独逐一座风积沙纯正。崇拜施工的中铁电气化局集团有限公司铁路工程公司修复者积极克服纯正粉细砂、浅埋、顾虑夹层等不良地质影响,实行加强地质监测、严控火药使用、配备智能衬砌台车等轨范,确保了纯正安全获胜意会。
据中铁电气化局集通神色现场崇拜东说念主郜鹏星先容,在风积沙地段进行纯正施责任业,存在容易发生沙子塌漏,以至里面塌方的风险,施工中采纳地表旋喷桩、超前水平旋喷桩加固,采纳三台阶临时仰拱法等工艺进行科学施工,攻克了风积沙地段开挖施工技巧贫苦。
集通铁路横贯内蒙古中东部,是“蒙煤东运”大通说念,是接洽我国东北、华北、西北地区动力和物质供应的遑急铁路主线。2020年4月启动电气化改动,全线共923公里。改动完成后,客货运载才调将大幅擢升,年货运量将由3600多万吨提高至8000万吨以上,搭客列车速率将从65公里/小时提高至最高运转速率120公里/小时,全程运转时代将裁减6个小时控制。
