3月下旬(xun)，國(guo)內(nei)(nei)在建第三大(da)水(shui)電工(gong)程(cheng)(cheng)(cheng)——向(xiang)家(jia)壩(ba)工(gong)程(cheng)(cheng)(cheng)左岸(an)一期(qi)(qi)384米高程(cheng)(cheng)(cheng)冷水(shui)廠完成內(nei)(nei)部設備(bei)約束解除工(gong)作(zuo)，全面進入(ru)設備(bei)拆除實施階(jie)段。拆除后的設備(bei)將整體搬遷(qian)至向(xiang)家(jia)壩(ba)右(you)岸(an)二(er)(er)期(qi)(qi)工(gong)程(cheng)(cheng)(cheng)消力池245米高程(cheng)(cheng)(cheng)部位，繼續為葛洲壩(ba)集團承擔的向(xiang)家(jia)壩(ba)二(er)(er)期(qi)(qi)工(gong)程(cheng)(cheng)(cheng)高強(qiang)度混凝土澆筑提供冷水(shui)養護所需(xu)。
在(zai)大(da)壩(ba)混(hun)凝(ning)(ning)土(tu)(tu)澆(jiao)筑施(shi)(shi)工(gong)(gong)(gong)中，給壩(ba)體(ti)輸送冷(leng)卻水(shui)降溫(wen)，是(shi)防止(zhi)混(hun)凝(ning)(ning)土(tu)(tu)凝(ning)(ning)固過程(cheng)中，產生熱(re)效應而造成大(da)壩(ba)裂紋(wen)必不可少的施(shi)(shi)工(gong)(gong)(gong)環節。隨著目前向(xiang)家壩(ba)二(er)期工(gong)(gong)(gong)程(cheng)混(hun)凝(ning)(ning)土(tu)(tu)施(shi)(shi)工(gong)(gong)(gong)快速推(tui)進以及氣溫(wen)上升，現有的三座(zuo)移(yi)動冷(leng)水(shui)站冷(leng)卻水(shui)供應能力已(yi)不能滿(man)足混(hun)凝(ning)(ning)土(tu)(tu)施(shi)(shi)工(gong)(gong)(gong)降溫(wen)養(yang)護需求。為此(ci)，葛(ge)洲壩(ba)集團向(xiang)家壩(ba)施(shi)(shi)工(gong)(gong)(gong)局精心謀劃(hua)，提前準備，作出將一期工(gong)(gong)(gong)程(cheng)冷(leng)水(shui)廠整體(ti)搬(ban)遷至向(xiang)家壩(ba)二(er)期工(gong)(gong)(gong)程(cheng)的施(shi)(shi)工(gong)(gong)(gong)方案。
384米高(gao)程冷(leng)(leng)水(shui)廠配置了國內最先進(jin)的(de)第三代螺(luo)桿式冷(leng)(leng)水(shui)機組，為向(xiang)(xiang)家(jia)壩一期工(gong)程做出(chu)了貢獻。目前新水(shui)廠的(de)前期設備(bei)轉運以(yi)及基礎埋件施(shi)工(gong)正有序進(jin)行中，新建的(de)245米高(gao)程冷(leng)(leng)水(shui)廠設備(bei)將主(zhu)要承擔向(xiang)(xiang)家(jia)壩二期工(gong)程左、右岸擋墻以(yi)及即將全(quan)面展開施(shi)工(gong)的(de)升船機項目提(ti)供冷(leng)(leng)卻(que)供水(shui)任務，計劃于今年4月底(di)投入生(sheng)產運行。
