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。
鋼構橋(qiao)基(ji)礎(chu)工(gong)(gong)(gong)(gong)程(cheng)(cheng)是向家(jia)壩(ba)(ba)水(shui)電站二期(qi)基(ji)坑(keng)開挖(wa)出碴及(ji)水(shui)工(gong)(gong)(gong)(gong)機械設(she)備運輸的交通主干道，也是今年(nian)底向家(jia)壩(ba)(ba)水(shui)電站實(shi)(shi)現二期(qi)基(ji)坑(keng)開挖(wa)向混(hun)凝(ning)土澆筑轉序的重點施工(gong)(gong)(gong)(gong)項(xiang)目。鋼構橋(qiao)基(ji)礎(chu)布置在右非5至右非6壩(ba)(ba)段壩(ba)(ba)后267至298米高程(cheng)(cheng)的高邊坡上(shang)，全長1600 米，垂直高度31米，混(hun)凝(ning)土澆筑17000立方米，具有施工(gong)(gong)(gong)(gong)難度大(da)、工(gong)(gong)(gong)(gong)期(qi)緊、工(gong)(gong)(gong)(gong)序復雜、質量(liang)要求高等特點。自6月20日開工(gong)(gong)(gong)(gong)以來，葛洲壩(ba)(ba)人(ren)優化資源配置，科學組織施工(gong)(gong)(gong)(gong)，強(qiang)化安(an)全管理，確(que)保了施工(gong)(gong)(gong)(gong)順利進行。截至目前(qian)，鋼構橋(qiao)壩(ba)(ba)后段基(ji)礎(chu)及(ji)貼坡墩柱施工(gong)(gong)(gong)(gong)已基(ji)本完工(gong)(gong)(gong)(gong)，壩(ba)(ba)身段及(ji)壩(ba)(ba)前(qian)段也全部達到296米高程(cheng)(cheng)，為9月份鋼構橋(qiao)安(an)裝(zhuang)并實(shi)(shi)現月底全面(mian)通車奠定了堅實(shi)(shi)基(ji)礎(chu)。
