5月25日，葛洲壩(ba)集(ji)團承建的向家壩(ba)水(shui)(shui)電(dian)站一期主體工(gong)(gong)程(cheng)全(quan)線達到305米(mi)度汛(xun)高程(cheng)，比計劃工(gong)(gong)期提前(qian)6天(tian)，為向家壩(ba)水(shui)(shui)電(dian)站今年安全(quan)度訊和(he)二期工(gong)(gong)程(cheng)基坑順利開挖打下了堅實(shi)的基礎。
向(xiang)家壩(ba)水(shui)(shui)電(dian)站分兩期(qi)建設，一期(qi)工(gong)(gong)程由左岸大壩(ba)主(zhu)體、上下游縱(zong)向(xiang)碾(nian)壓混凝(ning)土(tu)圍(wei)堰、引水(shui)(shui)工(gong)(gong)程、泄水(shui)(shui)工(gong)(gong)程、導流工(gong)(gong)程、沖砂孔(kong)壩(ba)段(duan)等建筑(zhu)物組成，混凝(ning)土(tu)澆(jiao)筑(zhu)總量(liang)305萬立方(fang)米(mi)。二期(qi)工(gong)(gong)程主(zhu)要(yao)包(bao)括基(ji)坑開(kai)挖(wa)和混凝(ning)土(tu)澆(jiao)筑(zhu)。5月底前(qian)，一期(qi)主(zhu)體混凝(ning)土(tu)澆(jiao)筑(zhu)全線達到305米(mi)度(du)汛高程，是(shi)確保二期(qi)工(gong)(gong)程安(an)全度(du)汛和正常(chang)施工(gong)(gong)的重要(yao)屏障。
葛(ge)洲(zhou)壩集團向家壩施(shi)工(gong)(gong)局(ju)混凝土項(xiang)目部克服工(gong)(gong)期緊(jin)、施(shi)工(gong)(gong)難度大(da)、澆(jiao)筑手段不足、施(shi)工(gong)(gong)工(gong)(gong)藝(yi)復雜等困難，科學組織生產，規(gui)范(fan)項(xiang)目管理，大(da)力開(kai)展“爭創(chuang)先鋒號(hao)班組，爭當‘技術型’工(gong)(gong)人”的(de)技術創(chuang)新勞動(dong)(dong)競賽活動(dong)(dong)，使工(gong)(gong)程(cheng)建設快速(su)向前推(tui)進。
目前，向(xiang)家壩水電(dian)站一期(qi)(qi)主體(ti)工程(cheng)施工還在緊張(zhang)進行(xing)中(zhong)，混凝(ning)土澆筑方量僅剩35萬立方米(mi)；二(er)期(qi)(qi)基坑開挖(wa)也正(zheng)順利(li)進行(xing)中(zhong)，年底有望澆筑首倉(cang)混凝(ning)土。
