世界最高雙曲拱壩——錦屏一級水電站混凝土雙曲拱壩將于8月中下旬正式開倉澆筑。目前，承擔右岸大壩混凝土澆筑任務的葛洲壩集團錦屏施工局已從人員、設備和技術等方面作好迎戰準備。
錦(jin)屏一級水電站大壩(ba)(ba)(ba)(ba)壩(ba)(ba)(ba)(ba)頂(ding)高(gao)(gao)程(cheng)(cheng)1885米(mi)，建基面(mian)高(gao)(gao)程(cheng)(cheng)1580米(mi)，最大壩(ba)(ba)(ba)(ba)高(gao)(gao)305米(mi)，為世界(jie)第一高(gao)(gao)雙曲(qu)拱壩(ba)(ba)(ba)(ba)，壩(ba)(ba)(ba)(ba)體混凝土澆筑總方量約528萬立方米(mi)。葛洲壩(ba)(ba)(ba)(ba)集(ji)團承擔了(le)大壩(ba)(ba)(ba)(ba)右(you)岸14號(hao)至26號(hao)壩(ba)(ba)(ba)(ba)段(duan)混凝土澆筑任務(wu)，混凝土澆筑總量約252萬立方米(mi)，鋼筋(jin)制安約2.12萬噸，預計于(yu)今年8月15日(ri)開始澆筑，主體部分于(yu)2013年8月底澆筑到(dao)1885米(mi)設計高(gao)(gao)程(cheng)(cheng)，總工(gong)(gong)期49個月。該工(gong)(gong)程(cheng)(cheng)具有混凝土工(gong)(gong)程(cheng)(cheng)量大、澆筑強度高(gao)(gao)、持續時間長(chang)、質量和溫控要(yao)求高(gao)(gao)等特(te)點。
為將(jiang)世(shi)界最高(gao)混(hun)凝(ning)(ning)土(tu)(tu)雙曲拱壩(ba)(ba)(ba)(ba)建設(she)(she)(she)成精(jing)品工(gong)(gong)(gong)程、優質(zhi)工(gong)(gong)(gong)程，自2007年(nian)中標(biao)該項目(mu)以(yi)來，葛洲壩(ba)(ba)(ba)(ba)人科學謀劃，精(jing)心組(zu)(zu)織(zhi)，從三方面作好(hao)了迎戰準備(bei)：一是積極購置平倉機(ji)、振搗機(ji)、塔機(ji)等(deng)大(da)(da)壩(ba)(ba)(ba)(ba)混(hun)凝(ning)(ning)土(tu)(tu)澆筑所需的各種(zhong)(zhong)設(she)(she)(she)備(bei)，安全、高(gao)效建設(she)(she)(she)大(da)(da)壩(ba)(ba)(ba)(ba)混(hun)凝(ning)(ning)土(tu)(tu)拌合(he)(he)系(xi)統(tong)。目(mu)前(qian)，大(da)(da)壩(ba)(ba)(ba)(ba)澆筑所需的各種(zhong)(zhong)設(she)(she)(she)備(bei)已進(jin)場(chang)，大(da)(da)壩(ba)(ba)(ba)(ba)混(hun)凝(ning)(ning)土(tu)(tu)拌合(he)(he)系(xi)統(tong)已建成并投入使用；二(er)是加強了人力資源(yuan)配(pei)置，錦屏施(shi)工(gong)(gong)(gong)局(ju)從小(xiao)灣、溪洛渡等(deng)大(da)(da)型水電工(gong)(gong)(gong)程項目(mu)部抽調了一批經驗豐富的施(shi)工(gong)(gong)(gong)管(guan)理、技術(shu)、作業人員，并自去(qu)年(nian)進(jin)場(chang)后結(jie)(jie)合(he)(he)工(gong)(gong)(gong)程實際(ji)組(zu)(zu)織(zhi)開展了多種(zhong)(zhong)培訓，提(ti)高(gao)了全體參戰人員的綜合(he)(he)素質(zhi)和(he)業務技能；三是組(zu)(zu)織(zhi)精(jing)干(gan)技術(shu)人員編(bian)寫施(shi)工(gong)(gong)(gong)設(she)(she)(she)計方案，并結(jie)(jie)合(he)(he)工(gong)(gong)(gong)程實際(ji)和(he)施(shi)工(gong)(gong)(gong)中出(chu)現的新問(wen)題，不斷優化施(shi)工(gong)(gong)(gong)方案。在近日(ri)召開的錦屏一級(ji)右(you)岸大(da)(da)壩(ba)(ba)(ba)(ba)混(hun)凝(ning)(ning)土(tu)(tu)施(shi)工(gong)(gong)(gong)技術(shu)方案評(ping)審會上，30余位國內知名水電專家對右(you)岸大(da)(da)壩(ba)(ba)(ba)(ba)混(hun)凝(ning)(ning)土(tu)(tu)施(shi)工(gong)(gong)(gong)技術(shu)方案進(jin)行(xing)了認真評(ping)審，為即將(jiang)開工(gong)(gong)(gong)的右(you)岸大(da)(da)壩(ba)(ba)(ba)(ba)混(hun)凝(ning)(ning)土(tu)(tu)澆筑優質(zhi)、高(gao)效進(jin)行(xing)提(ti)供(gong)了技術(shu)保證。
目前，錦屏(ping)施(shi)工(gong)局正組織力量，全力以赴進行右岸大壩基坑開挖(wa)(wa)施(shi)工(gong)，確保基坑開挖(wa)(wa)于(yu)7月底達到(dao)1580米(mi)設計高程，為大壩右岸混凝土(tu)澆筑創造(zao)條(tiao)件。
