12月10日，滇中引水昆明6標昆呈隧洞(dong)10號支(zhi)洞(dong)平洞(dong)開挖至主洞(dong)處，與主洞(dong)段實現順利交匯。

昆(kun)呈(cheng)隧(sui)洞(dong)全長(chang)56.58公里，具有主(zhu)洞(dong)線路長(chang)、合同工(gong)(gong)期長(chang)；圍巖(yan)變化(hua)大、物流(liu)組織難(nan)度(du)大；社會關(guan)注度(du)高(gao)、安全風(feng)險高(gao)、環(huan)水保要(yao)求高(gao)的“兩(liang)長(chang)兩(liang)大三高(gao)”特點，施(shi)(shi)(shi)工(gong)(gong)難(nan)度(du)和風(feng)險極大。截至(zhi)12月10日，昆(kun)呈(cheng)隧(sui)洞(dong)10#施(shi)(shi)(shi)工(gong)(gong)支(zhi)洞(dong)已完成(cheng)開挖支(zhi)護(hu)1019.571米，順利掘進至(zhi)主(zhu)洞(dong)，較(jiao)計劃工(gong)(gong)期提(ti)前377天(tian)，為下一步主(zhu)洞(dong)施(shi)(shi)(shi)工(gong)(gong)奠(dian)定堅實基礎。

滇(dian)中引水(shui)工(gong)(gong)(gong)(gong)(gong)程(cheng)是(shi)國務院確(que)定的(de)172項節水(shui)供水(shui)重(zhong)大(da)(da)水(shui)利工(gong)(gong)(gong)(gong)(gong)程(cheng)中的(de)標志性工(gong)(gong)(gong)(gong)(gong)程(cheng)，途經麗(li)江、大(da)(da)理、楚雄、昆明、玉溪(xi)、紅(hong)河，線路(lu)全長(chang)664.326公里，其中引水(shui)隧洞611公里，總工(gong)(gong)(gong)(gong)(gong)期(qi)96個月，是(shi)云南省有史(shi)以來(lai)和目前(qian)全國在(zai)建的(de)引調水(shui)工(gong)(gong)(gong)(gong)(gong)程(cheng)中，投資規模最大(da)(da)、建設難度最大(da)(da)的(de)水(shui)利工(gong)(gong)(gong)(gong)(gong)程(cheng)。工(gong)(gong)(gong)(gong)(gong)程(cheng)竣工(gong)(gong)(gong)(gong)(gong)后每年平均(jun)引水(shui)量達(da)34.03億立方米，將有效緩解(jie)滇(dian)中缺(que)水(shui)的(de)困境。
