12月10日，滇中引水昆(kun)(kun)明6標昆(kun)(kun)呈(cheng)隧洞(dong)10號(hao)支洞(dong)平洞(dong)開挖至主洞(dong)處，與主洞(dong)段實現順利交(jiao)匯。
昆(kun)呈隧洞(dong)全長(chang)56.58公里，具有主(zhu)洞(dong)線路長(chang)、合(he)同(tong)工(gong)期長(chang)；圍巖(yan)變化大(da)(da)、物流(liu)組織難度大(da)(da)；社會關注度高、安(an)全風險(xian)高、環水保(bao)要求高的“兩長(chang)兩大(da)(da)三(san)高”特點，施工(gong)難度和風險(xian)極大(da)(da)。截至(zhi)12月10日，昆(kun)呈隧洞(dong)10#施工(gong)支洞(dong)已完成(cheng)開挖支護1019.571米，順(shun)利掘(jue)進至(zhi)主(zhu)洞(dong)，較計劃工(gong)期提前377天，為(wei)下一步(bu)主(zhu)洞(dong)施工(gong)奠(dian)定堅實(shi)基礎(chu)。
滇中引水(shui)(shui)(shui)(shui)工(gong)(gong)(gong)程是國務院(yuan)確定的(de)(de)172項節水(shui)(shui)(shui)(shui)供水(shui)(shui)(shui)(shui)重大(da)水(shui)(shui)(shui)(shui)利工(gong)(gong)(gong)程中的(de)(de)標志(zhi)性(xing)工(gong)(gong)(gong)程，途經麗江(jiang)、大(da)理、楚雄、昆明、玉溪(xi)、紅(hong)河，線路(lu)全長(chang)664.326公(gong)里，其(qi)中引水(shui)(shui)(shui)(shui)隧洞611公(gong)里，總(zong)工(gong)(gong)(gong)期96個月，是云南省有史以來和目前全國在(zai)建的(de)(de)引調水(shui)(shui)(shui)(shui)工(gong)(gong)(gong)程中，投(tou)資規(gui)模最(zui)大(da)、建設難度最(zui)大(da)的(de)(de)水(shui)(shui)(shui)(shui)利工(gong)(gong)(gong)程。工(gong)(gong)(gong)程竣工(gong)(gong)(gong)后(hou)每年平均引水(shui)(shui)(shui)(shui)量(liang)達34.03億立方米，將有效(xiao)緩解滇中缺水(shui)(shui)(shui)(shui)的(de)(de)困(kun)境。
