10月18日(ri)(ri)至22日(ri)(ri)，由中國工程院院士張(zhang)超然、譚(tan)靖夷、馬洪(hong)琪(qi)、鄭守仁和(he)20名專家(jia)組成的(de)(de)溪洛(luo)(luo)渡(du)導(dao)(dao)流(liu)洞(dong)(dong)截流(liu)驗(yan)(yan)(yan)收(shou)(shou)小(xiao)組，通過實(shi)地查(cha)勘、聽取檔案匯報、現(xian)場檢查(cha)、交流(liu)討論等方(fang)式(shi)，對溪洛(luo)(luo)渡(du)導(dao)(dao)流(liu)洞(dong)(dong)進行驗(yan)(yan)(yan)收(shou)(shou)，由中國水電(dian)(dian)建(jian)設集團(tuan)水電(dian)(dian)六局(ju)承擔的(de)(de)左岸1#~3#導(dao)(dao)流(liu)洞(dong)(dong)，洞(dong)(dong)挖成型(xing)好(hao)(hao)、混凝(ning)土澆筑(zhu)好(hao)(hao)、現(xian)場清理(li)整潔度高(gao)，驗(yan)(yan)(yan)收(shou)(shou)資料齊全，受(shou)到(dao)好(hao)(hao)評。三峽(xia)工程開發(fa)總(zong)公司副總(zong)經理(li)樊啟祥說：“六局(ju)的(de)(de)導(dao)(dao)流(liu)洞(dong)(dong)工程，從(cong)初始階段(duan)一直到(dao)驗(yan)(yan)(yan)收(shou)(shou)階段(duan)，抓(zhua)得緊、抓(zhua)得主動，各方(fang)面條(tiao)件創造得比較好(hao)(hao)，希望水電(dian)(dian)集團(tuan)在其他各項施工中繼續發(fa)揮帶頭(tou)作(zuo)用。”
溪洛渡水(shui)(shui)電(dian)(dian)站導流(liu)(liu)洞(dong)(dong)工(gong)(gong)(gong)程是大(da)江截流(liu)(liu)的(de)(de)關鍵項目，導流(liu)(liu)洞(dong)(dong)的(de)(de)分流(liu)(liu)條(tiao)件事關截流(liu)(liu)成敗，施工(gong)(gong)(gong)過程中，中國(guo)水(shui)(shui)電(dian)(dian)六局承(cheng)擔的(de)(de)左岸1#、2#、3#導流(liu)(liu)洞(dong)(dong)預裂爆(bao)(bao)破共(gong)獲(huo)得(de)業(ye)主評定(ding)的(de)(de)9個樣(yang)板段，創出了月石方洞(dong)(dong)挖(wa)27.1萬立方米(mi)的(de)(de)國(guo)內同類(lei)工(gong)(gong)(gong)程施工(gong)(gong)(gong)進(jin)度新(xin)(xin)紀(ji)錄，在(zai)Ⅲ—Ⅳ類(lei)圍巖中同時進(jin)行三個相鄰的(de)(de)最大(da)跨(kua)度達(da)34米(mi)的(de)(de)特(te)大(da)斷面(mian)洞(dong)(dong)室開挖(wa)與支護施工(gong)(gong)(gong)，創國(guo)內水(shui)(shui)電(dian)(dian)站地下洞(dong)(dong)挖(wa)跨(kua)度新(xin)(xin)紀(ji)錄。其中，“特(te)大(da)斷面(mian)導流(liu)(liu)洞(dong)(dong)開挖(wa)與襯(chen)砌(qi)”施工(gong)(gong)(gong)工(gong)(gong)(gong)藝，獲(huo)得(de)水(shui)(shui)電(dian)(dian)建設集團科技進(jin)步一等獎，經專家評定(ding)達(da)到國(guo)際先進(jin)水(shui)(shui)平。順利實(shi)施了1#－3#導流(liu)(liu)洞(dong)(dong)進(jin)口(kou)圍堰和出口(kou)圍堰385高程以上的(de)(de)爆(bao)(bao)破拆除(chu)，該(gai)爆(bao)(bao)破為國(guo)家A級爆(bao)(bao)破，實(shi)際效果良好。
據(ju)悉(xi)，三(san)峽工(gong)(gong)程開發總(zong)公司溪洛渡建(jian)設部，將(jiang)導流洞(dong)工(gong)(gong)程作為試點，優化混凝土(tu)配合(he)比，增加洞(dong)內混凝土(tu)澆筑強(qiang)度，在底板鋪設冷卻(que)水(shui)管，為大壩和廠房(fang)施(shi)工(gong)(gong)積(ji)累(lei)經驗(yan)和技(ji)術數據(ju)，因此，導流洞(dong)施(shi)工(gong)(gong)質量、外觀形(xing)象(xiang)成為專家組關(guan)注(zhu)的焦(jiao)點。
