3月(yue)31 日，隨(sui)著(zhu)丹江(jiang)口水電(dian)站左(zuo)岸18號(hao)壩段順利加高(gao)至(zhi)176.6米完建(jian)高(gao)程，由葛洲壩集團二(er)公司承建(jian)的丹江(jiang)口水電(dian)站左(zuo)岸大壩加高(gao)工(gong)程全線澆筑到頂，主(zhu)體混凝土施工(gong)告竣(jun)。
丹江口水電站大壩(ba)(ba)加高工(gong)(gong)(gong)程(cheng)(cheng)是南水北調中(zhong)線的(de)源頭、龍(long)頭工(gong)(gong)(gong)程(cheng)(cheng)，也是目前國內最大的(de)水利樞紐改擴建工(gong)(gong)(gong)程(cheng)(cheng)，具有新老(lao)混凝(ning)土結合難(nan)(nan)、工(gong)(gong)(gong)期緊(jin)、任(ren)務重(zhong)等特點(dian)。葛洲壩(ba)(ba)集團二公司(si)承(cheng)建的(de)左(zuo)岸大壩(ba)(ba)加高工(gong)(gong)(gong)程(cheng)(cheng)主要(yao)由16號(hao)至44號(hao)混凝(ning)土壩(ba)(ba)段和(he)左(zuo)岸土石壩(ba)(ba)組成，壩(ba)(ba)頂設計高程(cheng)(cheng)176.6米。自(zi)2005年開(kai)工(gong)(gong)(gong)以來，二公司(si)積(ji)極開(kai)展科技攻(gong)關(guan)，優化施(shi)工(gong)(gong)(gong)方案，克(ke)服(fu)了(le)施(shi)工(gong)(gong)(gong)場地狹窄(zhai)、設備布置困難(nan)(nan)等諸多難(nan)(nan)題，確保(bao)了(le)施(shi)工(gong)(gong)(gong)進度、質量和(he)安全。
作為(wei)丹江(jiang)口水電站(zhan)大(da)壩(ba)最(zui)后一(yi)(yi)個主體加(jia)(jia)高(gao)(gao)施(shi)工(gong)(gong)部位，18號(hao)壩(ba)段的(de)施(shi)工(gong)(gong)難度非(fei)常(chang)大(da)，技(ji)術復雜。為(wei)攻克左岸大(da)壩(ba)加(jia)(jia)高(gao)(gao)的(de)最(zui)后一(yi)(yi)個攔路(lu)虎，葛洲壩(ba)集團一(yi)(yi)方面組成專(zhuan)家組逐項進(jin)(jin)行技(ji)術攻關，一(yi)(yi)方面充分利用前期(qi)加(jia)(jia)高(gao)(gao)積(ji)累的(de)豐富施(shi)工(gong)(gong)經驗，強化(hua)施(shi)工(gong)(gong)工(gong)(gong)藝，科學(xue)組織施(shi)工(gong)(gong)，使工(gong)(gong)程(cheng)建設按計劃順利推進(jin)(jin)。
3月31 日，歷經四年多的艱苦奮戰，葛洲壩人以自己的聰明(ming)才智為丹江(jiang)口水(shui)電站大壩左岸主體(ti)混凝(ning)土施(shi)工劃上了一(yi)個圓滿的句號，為早日實現(xian)一(yi)江(jiang)碧水(shui)進京城打下了堅(jian)實的基礎。
