經過近50天的緊張施工，目前，葛洲壩集團向家壩施工局混凝土項目部承建的向家壩水電站二期工程主干道鋼構橋基礎施工已進入最后沖剌階段。
鋼(gang)構(gou)橋基(ji)(ji)礎(chu)工(gong)(gong)程是向家壩(ba)(ba)(ba)水電(dian)站(zhan)二期(qi)(qi)基(ji)(ji)坑(keng)開挖出(chu)碴及水工(gong)(gong)機械設備運輸的交通主干(gan)道，也(ye)是今年底向家壩(ba)(ba)(ba)水電(dian)站(zhan)實(shi)現(xian)二期(qi)(qi)基(ji)(ji)坑(keng)開挖向混凝土澆筑(zhu)轉序(xu)的重點施(shi)工(gong)(gong)項(xiang)目。鋼(gang)構(gou)橋基(ji)(ji)礎(chu)布置(zhi)在右非(fei)5至右非(fei)6壩(ba)(ba)(ba)段(duan)壩(ba)(ba)(ba)后267至298米高(gao)(gao)(gao)程的高(gao)(gao)(gao)邊坡上，全(quan)長1600 米，垂直高(gao)(gao)(gao)度31米，混凝土澆筑(zhu)17000立方米，具有(you)施(shi)工(gong)(gong)難度大、工(gong)(gong)期(qi)(qi)緊、工(gong)(gong)序(xu)復雜(za)、質(zhi)量要求高(gao)(gao)(gao)等特點。自6月20日開工(gong)(gong)以來，葛洲壩(ba)(ba)(ba)人優(you)化資源配置(zhi)，科學(xue)組(zu)織施(shi)工(gong)(gong)，強化安全(quan)管理，確保了施(shi)工(gong)(gong)順利進行。截至目前，鋼(gang)構(gou)橋壩(ba)(ba)(ba)后段(duan)基(ji)(ji)礎(chu)及貼坡墩柱施(shi)工(gong)(gong)已基(ji)(ji)本(ben)完工(gong)(gong)，壩(ba)(ba)(ba)身(shen)段(duan)及壩(ba)(ba)(ba)前段(duan)也(ye)全(quan)部達到296米高(gao)(gao)(gao)程，為9月份鋼(gang)構(gou)橋安裝并實(shi)現(xian)月底全(quan)面(mian)通車奠(dian)定了堅實(shi)基(ji)(ji)礎(chu)。
