　　日前，葛洲壩集團參建的小灣水電站順利通過第二階段下閘蓄水現場檢查驗收，為電站9月底首臺機組發電奠定了堅實基礎。

　　位于云南(nan)省西(xi)部(bu)(bu)南(nan)澗縣與鳳(feng)慶縣交界(jie)處的(de)小灣(wan)(wan)水(shui)(shui)電(dian)(dian)(dian)(dian)站(zhan)，系瀾滄江(jiang)中(zhong)下游河段(duan)規(gui)劃(hua)八個梯(ti)級(ji)中(zhong)的(de)第(di)二(er)(er)級(ji)，電(dian)(dian)(dian)(dian)站(zhan)總(zong)裝機(ji)容量420萬千(qian)瓦，設計壩(ba)(ba)高(gao)(gao)(gao)(gao)292米(mi)，是目(mu)前(qian)世(shi)界(jie)在(zai)建第(di)二(er)(er)高(gao)(gao)(gao)(gao)雙曲拱(gong)壩(ba)(ba)。根(gen)據工(gong)期安(an)(an)排，電(dian)(dian)(dian)(dian)站(zhan)首臺機(ji)組將(jiang)于今(jin)年(nian)9月(yue)底(di)投(tou)產發電(dian)(dian)(dian)(dian)。葛洲壩(ba)(ba)集團西(xi)南(nan)分公司小灣(wan)(wan)項(xiang)目(mu)部(bu)(bu)承擔了電(dian)(dian)(dian)(dian)站(zhan)左(zuo)岸(an)大(da)壩(ba)(ba)24號至43號壩(ba)(ba)段(duan)混(hun)凝(ning)土澆筑(zhu)及(ji)基礎灌(guan)漿、金結安(an)(an)裝施(shi)工(gong)任務(wu)，混(hun)凝(ning)土澆筑(zhu)總(zong)量約380萬立方米(mi)。開工(gong)以來，小灣(wan)(wan)項(xiang)目(mu)部(bu)(bu)按照“堅持高(gao)(gao)(gao)(gao)起點，確(que)立高(gao)(gao)(gao)(gao)標(biao)(biao)(biao)準(zhun)，追求(qiu)高(gao)(gao)(gao)(gao)水(shui)(shui)平，創品牌(pai)，創一流(liu)”的(de)總(zong)體工(gong)作(zuo)目(mu)標(biao)(biao)(biao)，科學組織(zhi)施(shi)工(gong)，確(que)保了工(gong)程(cheng)建設順(shun)利(li)(li)推進(jin)。2008年(nian)底(di)，第(di)一階(jie)段(duan)蓄(xu)水(shui)(shui)形象要求(qiu)——電(dian)(dian)(dian)(dian)站(zhan)導流(liu)洞(dong)下閘封(feng)堵目(mu)標(biao)(biao)(biao)順(shun)利(li)(li)實現。今(jin)年(nian)6月(yue)份以前(qian)，電(dian)(dian)(dian)(dian)站(zhan)第(di)二(er)(er)階(jie)段(duan)蓄(xu)水(shui)(shui)形象目(mu)標(biao)(biao)(biao)也順(shun)利(li)(li)實現：左(zuo)岸(an)大(da)壩(ba)(ba)最低壩(ba)(ba)段(duan)混(hun)凝(ning)土順(shun)利(li)(li)澆至1205.5米(mi)高(gao)(gao)(gao)(gao)程(cheng)，接縫(feng)灌(guan)漿達到1184.5米(mi)高(gao)(gao)(gao)(gao)程(cheng)，帷幕灌(guan)漿達到1170米(mi)高(gao)(gao)(gao)(gao)程(cheng)，固結灌(guan)漿達到1200米(mi)高(gao)(gao)(gao)(gao)程(cheng)，導流(liu)底(di)孔(kong)、中(zhong)孔(kong)及(ji)放空底(di)孔(kong)、泄洪中(zhong)孔(kong)具備(bei)過(guo)流(liu)條件(jian)。6月(yue)中(zhong)旬，小灣(wan)(wan)水(shui)(shui)電(dian)(dian)(dian)(dian)站(zhan)順(shun)利(li)(li)通過(guo)了專家組進(jin)行的(de)現場(chang)檢(jian)查驗收。
