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)(gang)構橋(qiao)基礎(chu)(chu)工(gong)(gong)程是(shi)向(xiang)家壩(ba)(ba)(ba)水(shui)電站二期(qi)基坑開挖出碴及水(shui)工(gong)(gong)機械(xie)設備運輸的交通主干道，也是(shi)今(jin)年底向(xiang)家壩(ba)(ba)(ba)水(shui)電站實現二期(qi)基坑開挖向(xiang)混凝(ning)土澆筑轉序的重(zhong)點施(shi)工(gong)(gong)項目。鋼(gang)(gang)構橋(qiao)基礎(chu)(chu)布置(zhi)(zhi)在右非5至(zhi)右非6壩(ba)(ba)(ba)段壩(ba)(ba)(ba)后267至(zhi)298米高程的高邊坡上，全(quan)長1600 米，垂直高度(du)(du)31米，混凝(ning)土澆筑17000立方米，具有(you)施(shi)工(gong)(gong)難度(du)(du)大、工(gong)(gong)期(qi)緊、工(gong)(gong)序復雜、質量要求高等特點。自6月20日開工(gong)(gong)以來，葛(ge)洲壩(ba)(ba)(ba)人優化(hua)資源配置(zhi)(zhi)，科學組織(zhi)施(shi)工(gong)(gong)，強化(hua)安全(quan)管理(li)，確保(bao)了施(shi)工(gong)(gong)順利進行。截至(zhi)目前，鋼(gang)(gang)構橋(qiao)壩(ba)(ba)(ba)后段基礎(chu)(chu)及貼坡墩(dun)柱施(shi)工(gong)(gong)已基本完工(gong)(gong)，壩(ba)(ba)(ba)身段及壩(ba)(ba)(ba)前段也全(quan)部達到296米高程，為(wei)9月份鋼(gang)(gang)構橋(qiao)安裝并實現月底全(quan)面通車奠定了堅實基礎(chu)(chu)。
