10月18日(ri)至22日(ri)，由中國工(gong)程(cheng)(cheng)院院士張超(chao)然、譚靖夷、馬洪(hong)琪、鄭(zheng)守仁和(he)20名專家組成(cheng)的溪洛(luo)渡導(dao)(dao)流(liu)(liu)(liu)洞(dong)截(jie)流(liu)(liu)(liu)驗(yan)收小組，通過實地查勘、聽取檔(dang)案(an)匯報、現場檢(jian)查、交流(liu)(liu)(liu)討論等方(fang)式(shi)，對溪洛(luo)渡導(dao)(dao)流(liu)(liu)(liu)洞(dong)進(jin)行驗(yan)收，由中國水(shui)(shui)(shui)電(dian)建設集(ji)團水(shui)(shui)(shui)電(dian)六局承擔(dan)的左岸1#~3#導(dao)(dao)流(liu)(liu)(liu)洞(dong)，洞(dong)挖成(cheng)型好、混凝土澆(jiao)筑(zhu)好、現場清理整潔度(du)高，驗(yan)收資料齊全，受到(dao)好評。三峽工(gong)程(cheng)(cheng)開(kai)發總公(gong)司副總經理樊啟(qi)祥(xiang)說：“六局的導(dao)(dao)流(liu)(liu)(liu)洞(dong)工(gong)程(cheng)(cheng)，從初(chu)始(shi)階段(duan)一直(zhi)到(dao)驗(yan)收階段(duan)，抓得緊、抓得主動，各(ge)方(fang)面條件創造得比較好，希望水(shui)(shui)(shui)電(dian)集(ji)團在其他各(ge)項施工(gong)中繼續發揮帶頭(tou)作用。”
溪洛渡水電(dian)站(zhan)導(dao)(dao)流(liu)(liu)洞(dong)(dong)工(gong)(gong)(gong)程(cheng)(cheng)是大(da)(da)江截(jie)流(liu)(liu)的(de)(de)關鍵項目，導(dao)(dao)流(liu)(liu)洞(dong)(dong)的(de)(de)分流(liu)(liu)條件(jian)事關截(jie)流(liu)(liu)成(cheng)敗(bai)，施(shi)工(gong)(gong)(gong)過程(cheng)(cheng)中，中國水電(dian)六局承擔的(de)(de)左岸1#、2#、3#導(dao)(dao)流(liu)(liu)洞(dong)(dong)預裂(lie)爆(bao)(bao)(bao)破(po)(po)(po)共獲(huo)(huo)得業主(zhu)評定的(de)(de)9個(ge)(ge)樣板段，創出了月石(shi)方(fang)(fang)洞(dong)(dong)挖27.1萬立方(fang)(fang)米的(de)(de)國內(nei)同(tong)類(lei)工(gong)(gong)(gong)程(cheng)(cheng)施(shi)工(gong)(gong)(gong)進(jin)(jin)(jin)度(du)新(xin)紀錄，在Ⅲ—Ⅳ類(lei)圍(wei)巖(yan)中同(tong)時進(jin)(jin)(jin)行三個(ge)(ge)相鄰(lin)的(de)(de)最大(da)(da)跨(kua)度(du)達34米的(de)(de)特大(da)(da)斷面(mian)洞(dong)(dong)室(shi)開(kai)挖與(yu)支(zhi)護施(shi)工(gong)(gong)(gong)，創國內(nei)水電(dian)站(zhan)地(di)下洞(dong)(dong)挖跨(kua)度(du)新(xin)紀錄。其中，“特大(da)(da)斷面(mian)導(dao)(dao)流(liu)(liu)洞(dong)(dong)開(kai)挖與(yu)襯砌”施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝，獲(huo)(huo)得水電(dian)建設集(ji)團科技進(jin)(jin)(jin)步一等獎，經專家(jia)(jia)評定達到國際先進(jin)(jin)(jin)水平。順利實(shi)施(shi)了1#－3#導(dao)(dao)流(liu)(liu)洞(dong)(dong)進(jin)(jin)(jin)口圍(wei)堰和(he)出口圍(wei)堰385高程(cheng)(cheng)以上的(de)(de)爆(bao)(bao)(bao)破(po)(po)(po)拆(chai)除，該(gai)爆(bao)(bao)(bao)破(po)(po)(po)為國家(jia)(jia)A級爆(bao)(bao)(bao)破(po)(po)(po)，實(shi)際效果良好。
據悉，三峽工程開發總公司溪洛渡建設部，將導流洞(dong)工程作(zuo)為(wei)試點，優化(hua)混(hun)凝(ning)(ning)土配合比，增加洞(dong)內混(hun)凝(ning)(ning)土澆筑(zhu)強度，在底板鋪設冷卻水管，為(wei)大壩(ba)和廠房施工積累(lei)經驗和技術數(shu)據，因(yin)此，導流洞(dong)施工質量(liang)、外觀(guan)形象成為(wei)專(zhuan)家組關注的焦點。
