　　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(dian)站(zhan)大壩(ba)(ba)壩(ba)(ba)頂高(gao)程1885米(mi)，建基面高(gao)程1580米(mi)，最大壩(ba)(ba)高(gao)305米(mi)，為世界第一高(gao)雙曲拱壩(ba)(ba)，壩(ba)(ba)體(ti)混(hun)(hun)凝(ning)土澆(jiao)筑總方量(liang)約528萬立方米(mi)。葛洲壩(ba)(ba)集團承擔了大壩(ba)(ba)右岸14號至(zhi)26號壩(ba)(ba)段混(hun)(hun)凝(ning)土澆(jiao)筑任務，混(hun)(hun)凝(ning)土澆(jiao)筑總量(liang)約252萬立方米(mi)，鋼筋制安約2.12萬噸，預計于今年8月15日開(kai)始澆(jiao)筑，主體(ti)部分于2013年8月底澆(jiao)筑到1885米(mi)設計高(gao)程，總工(gong)期49個月。該工(gong)程具有(you)混(hun)(hun)凝(ning)土工(gong)程量(liang)大、澆(jiao)筑強度(du)高(gao)、持(chi)續時間長(chang)、質量(liang)和溫控(kong)要求高(gao)等(deng)特(te)點。

　　為(wei)將世(shi)界最高(gao)混(hun)凝(ning)土(tu)(tu)(tu)雙(shuang)曲(qu)拱壩(ba)(ba)(ba)建設成(cheng)精(jing)品(pin)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)、優質工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)，自(zi)2007年中標(biao)該項(xiang)目以來(lai)，葛(ge)洲壩(ba)(ba)(ba)人(ren)科學謀劃(hua)，精(jing)心組織，從(cong)三方(fang)面作好了(le)(le)(le)迎戰(zhan)準備：一是積極(ji)購置(zhi)平倉(cang)機、振搗機、塔機等大(da)(da)壩(ba)(ba)(ba)混(hun)凝(ning)土(tu)(tu)(tu)澆(jiao)(jiao)筑所(suo)需(xu)(xu)的(de)(de)(de)各(ge)種設備，安全、高(gao)效(xiao)(xiao)建設大(da)(da)壩(ba)(ba)(ba)混(hun)凝(ning)土(tu)(tu)(tu)拌合(he)(he)系(xi)統。目前，大(da)(da)壩(ba)(ba)(ba)澆(jiao)(jiao)筑所(suo)需(xu)(xu)的(de)(de)(de)各(ge)種設備已(yi)進場，大(da)(da)壩(ba)(ba)(ba)混(hun)凝(ning)土(tu)(tu)(tu)拌合(he)(he)系(xi)統已(yi)建成(cheng)并(bing)投入使用；二是加強了(le)(le)(le)人(ren)力資源配置(zhi)，錦屏(ping)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)局從(cong)小灣、溪洛渡等大(da)(da)型水(shui)(shui)電工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)項(xiang)目部抽(chou)調了(le)(le)(le)一批經驗豐富的(de)(de)(de)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)管(guan)理、技(ji)(ji)(ji)術(shu)、作業人(ren)員(yuan)，并(bing)自(zi)去年進場后結合(he)(he)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)實際(ji)組織開(kai)展了(le)(le)(le)多種培(pei)訓(xun)，提高(gao)了(le)(le)(le)全體(ti)參戰(zhan)人(ren)員(yuan)的(de)(de)(de)綜(zong)合(he)(he)素質和業務技(ji)(ji)(ji)能；三是組織精(jing)干技(ji)(ji)(ji)術(shu)人(ren)員(yuan)編寫(xie)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)設計方(fang)案，并(bing)結合(he)(he)工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)實際(ji)和施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)中出現的(de)(de)(de)新(xin)問題，不(bu)斷優化施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)方(fang)案。在近日(ri)召開(kai)的(de)(de)(de)錦屏(ping)一級右(you)(you)岸大(da)(da)壩(ba)(ba)(ba)混(hun)凝(ning)土(tu)(tu)(tu)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)技(ji)(ji)(ji)術(shu)方(fang)案評(ping)(ping)審會上(shang)，30余(yu)位(wei)國內知名水(shui)(shui)電專家(jia)對右(you)(you)岸大(da)(da)壩(ba)(ba)(ba)混(hun)凝(ning)土(tu)(tu)(tu)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)技(ji)(ji)(ji)術(shu)方(fang)案進行了(le)(le)(le)認(ren)真評(ping)(ping)審，為(wei)即將開(kai)工(gong)(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)右(you)(you)岸大(da)(da)壩(ba)(ba)(ba)混(hun)凝(ning)土(tu)(tu)(tu)澆(jiao)(jiao)筑優質、高(gao)效(xiao)(xiao)進行提供了(le)(le)(le)技(ji)(ji)(ji)術(shu)保證。
