11月29日，由中國水電(dian)建(jian)設(she)集團水電(dian)一(yi)局承建(jian)的小(xiao)灣(wan)水電(dian)站泄洪洞土建(jian)及(ji)金屬(shu)結構安裝(zhuang)工(gong)(gong)程提前(qian)33天(tian)，勝利(li)實(shi)現貫通，標志著工(gong)(gong)程進入了(le)一(yi)個(ge)嶄(zhan)新的施(shi)工(gong)(gong)階段。
小灣水電站泄(xie)洪洞(dong)全(quan)長1535.463米，泄(xie)洪洞(dong)洞(dong)身為(wei)有壓變(bian)無(wu)壓“龍抬(tai)頭”布(bu)置，由(you)進水口、有壓段、工作(zuo)閘門室、龍抬(tai)頭段、直槽斜坡段及(ji)出口挑流鼻坎組成(cheng)。
泄洪(hong)洞工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)是小灣水(shui)電站最后一(yi)(yi)個土建(jian)主(zhu)體工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)，也是參建(jian)施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)最大節點(dian)目(mu)標(biao)。為(wei)此，中國水(shui)電一(yi)(yi)局小灣項(xiang)目(mu)部以(yi)創建(jian)精品(pin)為(wei)目(mu)標(biao)，精心(xin)組織施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)、優化(hua)資源配置、強化(hua)過程(cheng)控制(zhi)、嚴抓質(zhi)量和(he)安全(quan)；面對洞身長、斷(duan)面大、地(di)質(zhi)條件差(cha)、洞型復雜多(duo)變(bian)、通(tong)風排(pai)煙難(nan)(nan)、施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)干(gan)擾多(duo)等(deng)施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)難(nan)(nan)點(dian)，他們(men)知(zhi)難(nan)(nan)而上，周密計劃(hua)，嚴格管控，不(bu)斷(duan)調整部署。為(wei)加快施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)進度，項(xiang)目(mu)部采取(qu)了有效措施(shi)，分工(gong)(gong)(gong)(gong)(gong)(gong)明確，責任(ren)到(dao)人，層(ceng)(ceng)層(ceng)(ceng)落實，層(ceng)(ceng)層(ceng)(ceng)到(dao)位，工(gong)(gong)(gong)(gong)(gong)(gong)序銜接緊(jin)湊(cou)，并針(zhen)對不(bu)良地(di)質(zhi)段，采取(qu)短進尺、弱爆破、多(duo)循環(huan)等(deng)施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)手段，積極拼搶工(gong)(gong)(gong)(gong)(gong)(gong)期，生產形勢始終(zhong)保(bao)持良好(hao)的態勢。今年(nian)四(si)季度，項(xiang)目(mu)部在工(gong)(gong)(gong)(gong)(gong)(gong)地(di)掀起大干(gan)高潮，使施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)速度不(bu)斷(duan)加快，達到(dao)“一(yi)(yi)天一(yi)(yi)個模樣”。
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。
