3月19日(ri)11時15分，葛洲壩集團(tuan)二公司(si)承建的丹江口(kou)水電站大壩加高左岸溢流壩段“四枯”閘墩，提前(qian)一個(ge)月全部(bu)加高到設(she)計高程(cheng)，為大壩2009年安全度汛創造(zao)了條件。
丹江(jiang)口水(shui)電站大(da)壩(ba)(ba)加(jia)高(gao)(gao)工(gong)(gong)(gong)程(cheng)是南水(shui)北調(diao)中(zhong)線水(shui)源工(gong)(gong)(gong)程(cheng)，也(ye)是目(mu)(mu)前(qian)國內最大(da)的水(shui)利樞紐改擴建(jian)工(gong)(gong)(gong)程(cheng)，建(jian)成(cheng)后(hou)不僅可(ke)以增加(jia)水(shui)庫調(diao)節能力，攔蓄更多來水(shui)調(diao)往北方，還(huan)可(ke)解(jie)決(jue)(jue)漢江(jiang)中(zhong)下(xia)(xia)游防洪(hong)的問(wen)題(ti)(ti)。葛洲(zhou)壩(ba)(ba)集(ji)團二公司丹江(jiang)口項(xiang)目(mu)(mu)部承擔了溢流壩(ba)(ba)段(duan)(duan)(duan)溢流面和(he)閘(zha)墩(dun)加(jia)固加(jia)高(gao)(gao)，非(fei)溢流壩(ba)(ba)段(duan)(duan)(duan)、廠(chang)房壩(ba)(ba)段(duan)(duan)(duan)和(he)左聯壩(ba)(ba)段(duan)(duan)(duan)下(xia)(xia)游貼(tie)坡和(he)壩(ba)(ba)頂加(jia)高(gao)(gao)等項(xiang)目(mu)(mu)的施工(gong)(gong)(gong)。合同工(gong)(gong)(gong)期為2005年(nian)8月至2010年(nian)4月30日。開(kai)工(gong)(gong)(gong)以來，葛洲(zhou)壩(ba)(ba)人認真開(kai)展技術攻關，成(cheng)功解(jie)決(jue)(jue)了初(chu)期老壩(ba)(ba)體(ti)結構拆(chai)除施工(gong)(gong)(gong)、初(chu)期壩(ba)(ba)頂裂縫(feng)處理(li)等難題(ti)(ti)，在復雜的施工(gong)(gong)(gong)條(tiao)件和(he)高(gao)(gao)危環境下(xia)(xia)強化質量、安全管(guan)理(li)，確保了工(gong)(gong)(gong)程(cheng)建(jian)設的安全、優質、高(gao)(gao)效推(tui)進。
據悉，閘墩(dun)加(jia)高全(quan)部(bu)到頂后，該(gai)項(xiang)目部(bu)將全(quan)面轉向(xiang)18號壩段度(du)汛(xun)棧橋安裝、門(men)塔機拆除以及16至17號壩段5000KN門(men)式啟(qi)閉機軌道(dao)梁安裝工作，向(xiang)“四枯(ku)”度(du)汛(xun)目標做最后沖刺。
