11月29日(ri)，由中國水電(dian)建設(she)集團水電(dian)一局承建的小灣水電(dian)站泄洪(hong)洞土建及金(jin)屬結構安裝工(gong)(gong)程提前33天，勝利實現(xian)貫(guan)通，標志著工(gong)(gong)程進入了一個嶄新的施工(gong)(gong)階段。
小灣水電站泄(xie)洪(hong)洞(dong)全長1535.463米，泄(xie)洪(hong)洞(dong)洞(dong)身為有壓(ya)(ya)(ya)變無壓(ya)(ya)(ya)“龍(long)抬(tai)頭(tou)(tou)”布置，由進水口、有壓(ya)(ya)(ya)段(duan)、工作閘門室、龍(long)抬(tai)頭(tou)(tou)段(duan)、直槽(cao)斜坡(po)段(duan)及出口挑(tiao)流鼻坎(kan)組成。
泄洪洞(dong)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)是小灣水電(dian)站最后一個(ge)土建主體工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)，也(ye)是參(can)建施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)最大節點目(mu)標。為(wei)此，中國水電(dian)一局小灣項(xiang)目(mu)部(bu)以創(chuang)建精品為(wei)目(mu)標，精心組織施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)、優化資源配置、強化過程(cheng)控制、嚴(yan)抓質量和安全；面對(dui)洞(dong)身長、斷面大、地(di)質條(tiao)件(jian)差、洞(dong)型復雜多(duo)變、通(tong)風排(pai)煙難、施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)干擾多(duo)等施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)難點，他們知難而上，周(zhou)密計劃(hua)，嚴(yan)格管控，不(bu)(bu)斷調整部(bu)署(shu)。為(wei)加快施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)進度，項(xiang)目(mu)部(bu)采(cai)取了有效措(cuo)施(shi)(shi)，分(fen)工(gong)(gong)(gong)(gong)(gong)(gong)明(ming)確(que)，責(ze)任到(dao)(dao)人，層層落實，層層到(dao)(dao)位，工(gong)(gong)(gong)(gong)(gong)(gong)序銜接緊(jin)湊(cou)，并(bing)針(zhen)對(dui)不(bu)(bu)良(liang)地(di)質段，采(cai)取短(duan)進尺、弱爆破(po)、多(duo)循環等施(shi)(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(xing)勢(shi)(shi)始終(zhong)保持良(liang)好的態勢(shi)(shi)。今年四季度，項(xiang)目(mu)部(bu)在(zai)工(gong)(gong)(gong)(gong)(gong)(gong)地(di)掀起大干高潮，使施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)速(su)度不(bu)(bu)斷加快，達到(dao)(dao)“一天(tian)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。
