12月10日，滇(dian)中引水昆明6標昆呈隧洞(dong)10號(hao)支洞(dong)平洞(dong)開挖至主洞(dong)處，與主洞(dong)段實現(xian)順利交(jiao)匯。
昆(kun)呈(cheng)隧(sui)洞(dong)全(quan)長(chang)(chang)56.58公里(li)，具(ju)有主洞(dong)線路長(chang)(chang)、合同工(gong)期長(chang)(chang)；圍巖變化大、物流(liu)組織難(nan)度(du)大；社會關注度(du)高(gao)、安全(quan)風(feng)險(xian)高(gao)、環水保(bao)要求高(gao)的“兩長(chang)(chang)兩大三高(gao)”特點(dian)，施工(gong)難(nan)度(du)和風(feng)險(xian)極(ji)大。截至12月10日，昆(kun)呈(cheng)隧(sui)洞(dong)10#施工(gong)支洞(dong)已完成(cheng)開挖(wa)支護1019.571米，順利掘進(jin)至主洞(dong)，較計劃(hua)工(gong)期提前377天(tian)，為下一步主洞(dong)施工(gong)奠定(ding)堅實基(ji)礎。
滇(dian)中引(yin)水(shui)(shui)(shui)工(gong)(gong)(gong)(gong)程(cheng)(cheng)是(shi)國務(wu)院確定(ding)的(de)172項(xiang)節水(shui)(shui)(shui)供水(shui)(shui)(shui)重(zhong)大(da)水(shui)(shui)(shui)利工(gong)(gong)(gong)(gong)程(cheng)(cheng)中的(de)標志性工(gong)(gong)(gong)(gong)程(cheng)(cheng)，途經麗江(jiang)、大(da)理、楚(chu)雄、昆明、玉溪、紅河，線路全長664.326公(gong)里，其中引(yin)水(shui)(shui)(shui)隧洞611公(gong)里，總(zong)工(gong)(gong)(gong)(gong)期96個月(yue)，是(shi)云南省有(you)史(shi)以(yi)來(lai)和目前(qian)全國在建的(de)引(yin)調水(shui)(shui)(shui)工(gong)(gong)(gong)(gong)程(cheng)(cheng)中，投資規模最(zui)大(da)、建設難(nan)度(du)最(zui)大(da)的(de)水(shui)(shui)(shui)利工(gong)(gong)(gong)(gong)程(cheng)(cheng)。工(gong)(gong)(gong)(gong)程(cheng)(cheng)竣工(gong)(gong)(gong)(gong)后每年(nian)平均引(yin)水(shui)(shui)(shui)量達34.03億立(li)方米，將(jiang)有(you)效緩解滇(dian)中缺水(shui)(shui)(shui)的(de)困境。
