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。
鋼構(gou)橋基(ji)礎(chu)(chu)工(gong)(gong)(gong)(gong)程是向家壩(ba)水電(dian)(dian)站二期(qi)(qi)基(ji)坑開(kai)挖(wa)出碴及(ji)水工(gong)(gong)(gong)(gong)機械設備(bei)運輸的(de)交(jiao)通(tong)(tong)主干道(dao)，也(ye)是今年底向家壩(ba)水電(dian)(dian)站實(shi)現二期(qi)(qi)基(ji)坑開(kai)挖(wa)向混凝土澆(jiao)筑轉序(xu)的(de)重點(dian)(dian)施工(gong)(gong)(gong)(gong)項目。鋼構(gou)橋基(ji)礎(chu)(chu)布置在右非(fei)5至右非(fei)6壩(ba)段(duan)壩(ba)后(hou)267至298米(mi)高程的(de)高邊坡上，全(quan)(quan)長1600 米(mi)，垂直(zhi)高度31米(mi)，混凝土澆(jiao)筑17000立方米(mi)，具(ju)有施工(gong)(gong)(gong)(gong)難度大、工(gong)(gong)(gong)(gong)期(qi)(qi)緊(jin)、工(gong)(gong)(gong)(gong)序(xu)復(fu)雜、質量要求高等特(te)點(dian)(dian)。自(zi)6月(yue)20日(ri)開(kai)工(gong)(gong)(gong)(gong)以來(lai)，葛(ge)洲壩(ba)人優化資源配(pei)置，科(ke)學組織施工(gong)(gong)(gong)(gong)，強化安全(quan)(quan)管理，確保了施工(gong)(gong)(gong)(gong)順利(li)進(jin)行。截至目前，鋼構(gou)橋壩(ba)后(hou)段(duan)基(ji)礎(chu)(chu)及(ji)貼坡墩(dun)柱施工(gong)(gong)(gong)(gong)已基(ji)本完工(gong)(gong)(gong)(gong)，壩(ba)身(shen)段(duan)及(ji)壩(ba)前段(duan)也(ye)全(quan)(quan)部(bu)達到296米(mi)高程，為9月(yue)份鋼構(gou)橋安裝并實(shi)現月(yue)底全(quan)(quan)面通(tong)(tong)車(che)奠(dian)定(ding)了堅實(shi)基(ji)礎(chu)(chu)。
