11月29日(ri)，由中國水電建設集團水電一局承(cheng)建的小(xiao)灣水電站(zhan)泄(xie)洪(hong)洞土建及金屬結構安(an)裝(zhuang)工程(cheng)提前33天，勝利實現(xian)貫通(tong)，標志著工程(cheng)進入了一個(ge)嶄新(xin)的施(shi)工階段。
小灣水電站泄洪(hong)洞(dong)(dong)全(quan)長1535.463米(mi)，泄洪(hong)洞(dong)(dong)洞(dong)(dong)身為(wei)有(you)壓(ya)變無壓(ya)“龍抬頭(tou)”布置，由進水口、有(you)壓(ya)段、工(gong)作閘門(men)室、龍抬頭(tou)段、直槽斜坡(po)段及出口挑(tiao)流鼻坎組成(cheng)。
泄洪洞工(gong)(gong)(gong)(gong)程是小灣(wan)水(shui)電站最后一個(ge)土(tu)建主體工(gong)(gong)(gong)(gong)程，也是參建施工(gong)(gong)(gong)(gong)最大節點目標。為(wei)此，中國水(shui)電一局小灣(wan)項(xiang)目部(bu)以創(chuang)建精(jing)品為(wei)目標，精(jing)心組織(zhi)施工(gong)(gong)(gong)(gong)、優化(hua)資(zi)源配置、強化(hua)過(guo)程控制、嚴(yan)抓質量和安全；面(mian)對洞身長、斷面(mian)大、地質條件(jian)差(cha)、洞型(xing)復雜(za)多(duo)變、通風排煙難(nan)、施工(gong)(gong)(gong)(gong)干擾(rao)多(duo)等(deng)施工(gong)(gong)(gong)(gong)難(nan)點，他們知難(nan)而上(shang)，周密計(ji)劃，嚴(yan)格管控，不斷調整部(bu)署。為(wei)加快(kuai)(kuai)施工(gong)(gong)(gong)(gong)進度(du)，項(xiang)目部(bu)采(cai)取了有效措施，分工(gong)(gong)(gong)(gong)明確，責任到人，層層落實，層層到位，工(gong)(gong)(gong)(gong)序(xu)銜接緊湊(cou)，并針(zhen)對不良(liang)地質段，采(cai)取短進尺、弱爆破(po)、多(duo)循環等(deng)施工(gong)(gong)(gong)(gong)手段，積極(ji)拼搶工(gong)(gong)(gong)(gong)期，生(sheng)產形勢始終保持良(liang)好(hao)的(de)態勢。今年(nian)四季度(du)，項(xiang)目部(bu)在工(gong)(gong)(gong)(gong)地掀起大干高(gao)潮，使施工(gong)(gong)(gong)(gong)速度(du)不斷加快(kuai)(kuai)，達到“一天一個(ge)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。
