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(qiao)基(ji)礎工(gong)(gong)(gong)(gong)程是向(xiang)(xiang)家(jia)(jia)壩(ba)水電(dian)(dian)站二(er)(er)期基(ji)坑(keng)開挖出碴及(ji)水工(gong)(gong)(gong)(gong)機械設(she)備運(yun)輸(shu)的(de)交通主干道，也是今年底向(xiang)(xiang)家(jia)(jia)壩(ba)水電(dian)(dian)站實現(xian)二(er)(er)期基(ji)坑(keng)開挖向(xiang)(xiang)混(hun)凝土澆筑轉序(xu)(xu)的(de)重點(dian)施工(gong)(gong)(gong)(gong)項目。鋼(gang)構(gou)橋(qiao)基(ji)礎布(bu)置在右(you)非5至(zhi)右(you)非6壩(ba)段(duan)壩(ba)后267至(zhi)298米高(gao)程的(de)高(gao)邊坡(po)(po)上，全(quan)(quan)長1600 米，垂直高(gao)度(du)31米，混(hun)凝土澆筑17000立方米，具有施工(gong)(gong)(gong)(gong)難度(du)大(da)、工(gong)(gong)(gong)(gong)期緊、工(gong)(gong)(gong)(gong)序(xu)(xu)復雜、質量要求高(gao)等(deng)特點(dian)。自6月(yue)20日(ri)開工(gong)(gong)(gong)(gong)以來(lai)，葛洲壩(ba)人優化資(zi)源配置，科學(xue)組織施工(gong)(gong)(gong)(gong)，強化安(an)全(quan)(quan)管理(li)，確保了施工(gong)(gong)(gong)(gong)順利(li)進行。截(jie)至(zhi)目前，鋼(gang)構(gou)橋(qiao)壩(ba)后段(duan)基(ji)礎及(ji)貼坡(po)(po)墩柱施工(gong)(gong)(gong)(gong)已基(ji)本完工(gong)(gong)(gong)(gong)，壩(ba)身段(duan)及(ji)壩(ba)前段(duan)也全(quan)(quan)部(bu)達到(dao)296米高(gao)程，為9月(yue)份鋼(gang)構(gou)橋(qiao)安(an)裝并實現(xian)月(yue)底全(quan)(quan)面(mian)通車奠定了堅實基(ji)礎。
