2月21日，由(you)云(yun)投(tou)鐵(tie)路(lu)參(can)與出資建設的中(zhong)(zhong)（國）老(lao)（撾）昆(kun)（明）萬（象）鐵(tie)路(lu)玉(yu)磨(mo)段(duan)安(an)定隧(sui)道(dao)(dao)1號斜井(jing)最后一模(mo)無砟軌道(dao)(dao)澆筑(zhu)完成(cheng)，標志著全(quan)(quan)長17476米的全(quan)(quan)線第一長隧(sui)安(an)定隧(sui)道(dao)(dao)無砟軌道(dao)(dao)施工全(quan)(quan)部完成(cheng)，為確保年(nian)內(nei)中(zhong)(zhong)老(lao)鐵(tie)路(lu)全(quan)(quan)線順利通車(che)創造有利條件。

安定隧道(dao)(dao)是中老昆萬(wan)鐵路(lu)頭號重難點工程，集涌(yong)水、斷層(ceng)、高巖溫等不良地質于(yu)一體(ti)。自2020年9月(yue)23日(ri)開始首段(duan)無砟軌道(dao)(dao)施工以來，克服重要節點都在(zai)關鍵線(xian)路(lu)上等諸多困難，優化施組、攻(gong)堅克難、開展勞動(dong)競(jing)賽，向一個個節點目標發起(qi)沖(chong)刺。

目前，安(an)定(ding)隧(sui)道進(jin)口(kou)(kou)右幅已經(jing)鋪(pu)軌4.3公里，鋪(pu)軌工(gong)(gong)(gong)(gong)(gong)作以每天5千米進(jin)度推進(jin)。無(wu)砟軌道是(shi)鐵路線(xian)下工(gong)(gong)(gong)(gong)(gong)程施工(gong)(gong)(gong)(gong)(gong)的最后一道工(gong)(gong)(gong)(gong)(gong)序。為(wei)打(da)通鋪(pu)軌前最后一個堵點，盡快達到鋪(pu)軌條件，承擔(dan)安(an)定(ding)隧(sui)道出(chu)口(kou)(kou)端線(xian)下施工(gong)(gong)(gong)(gong)(gong)任務(wu)的300多名建(jian)(jian)設者春節(jie)“不打(da)烊”，春節(jie)期間堅守工(gong)(gong)(gong)(gong)(gong)作崗位(wei)全力以赴搶抓建(jian)(jian)設，經(jing)過(guo)建(jian)(jian)設者們夜(ye)以繼日地連(lian)續(xu)作業，確(que)保安(an)定(ding)隧(sui)道線(xian)下主體工(gong)(gong)(gong)(gong)(gong)程順利(li)完(wan)工(gong)(gong)(gong)(gong)(gong)。

中老(lao)鐵(tie)路全(quan)長1000多公(gong)里建成(cheng)通車后云南省昆明市(shi)至(zhi)西雙版納傣(dai)族自治州(zhou)景洪(hong)市(shi)僅需3個多小時至(zhi)老(lao)撾萬象有(you)望夕(xi)發朝至(zhi)。
