5月(yue)25日，葛(ge)洲壩(ba)集團承建(jian)的(de)(de)向(xiang)家壩(ba)水(shui)電站一期(qi)主(zhu)體工(gong)程(cheng)全線達到305米(mi)度汛高程(cheng)，比(bi)計劃工(gong)期(qi)提前(qian)6天，為向(xiang)家壩(ba)水(shui)電站今年(nian)安(an)全度訊(xun)和二(er)期(qi)工(gong)程(cheng)基坑順利開挖打下了(le)堅實的(de)(de)基礎。
向家壩水(shui)電(dian)站(zhan)分兩(liang)期(qi)(qi)建設(she)，一(yi)期(qi)(qi)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)由左岸大壩主(zhu)(zhu)體、上(shang)下游縱向碾(nian)壓混(hun)(hun)凝(ning)土(tu)(tu)(tu)圍堰、引(yin)水(shui)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)、泄(xie)水(shui)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)、導流工(gong)(gong)(gong)程(cheng)(cheng)(cheng)、沖砂孔壩段等建筑物組成，混(hun)(hun)凝(ning)土(tu)(tu)(tu)澆(jiao)筑總量305萬立方米(mi)。二期(qi)(qi)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)主(zhu)(zhu)要包括基坑開挖和混(hun)(hun)凝(ning)土(tu)(tu)(tu)澆(jiao)筑。5月底前，一(yi)期(qi)(qi)主(zhu)(zhu)體混(hun)(hun)凝(ning)土(tu)(tu)(tu)澆(jiao)筑全線達到305米(mi)度汛(xun)高(gao)程(cheng)(cheng)(cheng)，是(shi)確保二期(qi)(qi)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)安全度汛(xun)和正常施工(gong)(gong)(gong)的重要屏障(zhang)。
葛(ge)洲(zhou)壩集(ji)團向(xiang)家壩施工(gong)(gong)局混凝土項目部克服工(gong)(gong)期緊、施工(gong)(gong)難度大(da)、澆筑(zhu)手(shou)段不足、施工(gong)(gong)工(gong)(gong)藝(yi)復雜等(deng)困難，科學組織(zhi)生產，規范項目管理，大(da)力開展“爭(zheng)創先鋒號(hao)班(ban)組，爭(zheng)當‘技術(shu)型(xing)’工(gong)(gong)人”的技術(shu)創新勞動競(jing)賽活動，使工(gong)(gong)程建(jian)設快速向(xiang)前推進。
目前(qian)，向家壩(ba)水電站一(yi)期(qi)主(zhu)體工程施工還(huan)在(zai)緊張進(jin)行中(zhong)，混(hun)凝(ning)土澆筑方(fang)量僅剩(sheng)35萬立方(fang)米(mi)；二期(qi)基坑開挖也正順利進(jin)行中(zhong)，年底有望澆筑首(shou)倉混(hun)凝(ning)土。
