9月18日下(xia)午(wu)，向(xiang)家(jia)壩(ba)水電站沖砂(sha)孔壩(ba)段丙塊混凝土順利澆筑，標(biao)志著(zhu)電站左岸大壩(ba)6個導流底(di)孔全部達到進水口(kou)底(di)板高程(cheng)，為向(xiang)家(jia)壩(ba)工程(cheng)年(nian)底(di)截流目標(biao)的實現打下(xia)了良(liang)好的基礎。
據了解(jie)，這(zhe)6個導流(liu)底孔(kong)分別布(bu)置(zhi)在向家壩(ba)水(shui)電站左非壩(ba)段及沖砂孔(kong)壩(ba)段內，每(mei)個導流(liu)底孔(kong)寬(kuan)10米(mi)(mi)，高14米(mi)(mi)。其中1號(hao)至4號(hao)導流(liu)底孔(kong)孔(kong)長(chang)(chang)152.5米(mi)(mi)，5號(hao)和6號(hao)導流(liu)底孔(kong)孔(kong)長(chang)(chang)220.45米(mi)(mi)。工(gong)(gong)(gong)程量(liang)大，結構復雜，質量(liang)要求高，施(shi)工(gong)(gong)(gong)難度大。承擔施(shi)工(gong)(gong)(gong)的葛(ge)洲壩(ba)集團向家壩(ba)施(shi)工(gong)(gong)(gong)局混凝(ning)土項目部，科學(xue)配置(zhi)資源，認真編制施(shi)工(gong)(gong)(gong)技(ji)術指導書，組(zu)織施(shi)工(gong)(gong)(gong)人員進行(xing)嚴(yan)格的培訓，確保了工(gong)(gong)(gong)程順利推進。
