11月29日，由中(zhong)國水(shui)電建設集(ji)團(tuan)水(shui)電一局承(cheng)建的(de)小灣水(shui)電站泄洪(hong)洞(dong)土建及金(jin)屬結構(gou)安(an)裝工(gong)程(cheng)提(ti)前(qian)33天，勝利實現貫通，標志(zhi)著工(gong)程(cheng)進入了一個(ge)嶄新的(de)施工(gong)階段。
小灣水(shui)電站泄洪洞(dong)(dong)全長1535.463米，泄洪洞(dong)(dong)洞(dong)(dong)身為有壓變無(wu)壓“龍抬頭(tou)”布置，由進水(shui)口、有壓段(duan)、工作閘門室、龍抬頭(tou)段(duan)、直槽斜坡段(duan)及(ji)出口挑(tiao)流鼻坎(kan)組成。
泄洪洞(dong)工(gong)(gong)(gong)(gong)(gong)程是(shi)小灣(wan)水電(dian)站最后一(yi)(yi)個土建(jian)主(zhu)體(ti)工(gong)(gong)(gong)(gong)(gong)程，也是(shi)參建(jian)施(shi)工(gong)(gong)(gong)(gong)(gong)最大(da)節點(dian)目(mu)標(biao)。為此，中國水電(dian)一(yi)(yi)局小灣(wan)項目(mu)部(bu)(bu)以創建(jian)精品為目(mu)標(biao)，精心組織施(shi)工(gong)(gong)(gong)(gong)(gong)、優化(hua)資源(yuan)配置、強化(hua)過(guo)程控(kong)制、嚴抓質量和(he)安全；面對洞(dong)身(shen)長(chang)、斷面大(da)、地(di)質條件差、洞(dong)型復雜多變、通(tong)風排煙難(nan)(nan)、施(shi)工(gong)(gong)(gong)(gong)(gong)干擾多等施(shi)工(gong)(gong)(gong)(gong)(gong)難(nan)(nan)點(dian)，他們(men)知難(nan)(nan)而上，周密計劃，嚴格管(guan)控(kong)，不(bu)(bu)斷調整部(bu)(bu)署。為加(jia)快施(shi)工(gong)(gong)(gong)(gong)(gong)進度(du)，項目(mu)部(bu)(bu)采取了有效措施(shi)，分工(gong)(gong)(gong)(gong)(gong)明確，責任(ren)到(dao)人，層(ceng)層(ceng)落(luo)實，層(ceng)層(ceng)到(dao)位(wei)，工(gong)(gong)(gong)(gong)(gong)序銜接(jie)緊(jin)湊，并針對不(bu)(bu)良地(di)質段(duan)，采取短進尺、弱爆破、多循環等施(shi)工(gong)(gong)(gong)(gong)(gong)手段(duan)，積(ji)極拼(pin)搶工(gong)(gong)(gong)(gong)(gong)期(qi)，生產(chan)形勢始終保持良好的態(tai)勢。今年四季度(du)，項目(mu)部(bu)(bu)在工(gong)(gong)(gong)(gong)(gong)地(di)掀起(qi)大(da)干高(gao)潮，使施(shi)工(gong)(gong)(gong)(gong)(gong)速(su)度(du)不(bu)(bu)斷加(jia)快，達到(dao)“一(yi)(yi)天(tian)一(yi)(yi)個模樣(yang)”。
施工中，中國水電一局的建設者加強現場安全管理，對施工質量進行嚴格控制，使施工的安全、質量整體處于受控狀態，創造了安全、質量無事故的好成績，泄洪洞工程比原計劃工期提前一個33天實現貫通。
