　　由中國水電集團下屬水電九局有限公司承建的貴州黃泥河老江底水電站，日前全部建成投產發電。

　　老江底(di)水(shui)(shui)電(dian)站位(wei)于貴州(zhou)省南盤(pan)江一(yi)級支流黃泥河(he)上，總裝機(ji)10萬(wan)千瓦，為(wei)三等中型電(dian)站，首(shou)部樞(shu)紐(niu)永久(jiu)性(xing)主要水(shui)(shui)工建(jian)筑物有攔河(he)大(da)壩(ba)、岸邊溢洪道(dao)、泄洪洞、引水(shui)(shui)系統及(ji)發電(dian)廠(chang)房(fang)等建(jian)筑物。攔河(he)大(da)壩(ba)設計(ji)為(wei)橢(tuo)圓雙曲(qu)薄拱壩(ba)，最大(da)壩(ba)高(gao)為(wei)75米，年平均發電(dian)量４·１８２億(yi)千瓦時。

　　該工(gong)(gong)(gong)程于2005年(nian)6月10日開工(gong)(gong)(gong)，施(shi)(shi)工(gong)(gong)(gong)中(zhong)(zhong)(zhong)(zhong)，中(zhong)(zhong)(zhong)(zhong)國水(shui)電九局(ju)針對施(shi)(shi)工(gong)(gong)(gong)場面(mian)十分狹窄、多處交叉作業、技術(shu)含量(liang)高(gao)(gao)、施(shi)(shi)工(gong)(gong)(gong)難度大、施(shi)(shi)工(gong)(gong)(gong)周期短等特點，加(jia)大科(ke)技攻關力度，積極推(tui)廣應用(yong)新技術(shu)、新工(gong)(gong)(gong)藝(yi)和(he)新材(cai)料(liao)，不(bu)斷提高(gao)(gao)項(xiang)目部施(shi)(shi)工(gong)(gong)(gong)水(shui)平。在(zai)(zai)兩壩(ba)(ba)(ba)肩高(gao)(gao)邊坡開挖中(zhong)(zhong)(zhong)(zhong)，采(cai)用(yong)深孔預(yu)裂爆破施(shi)(shi)工(gong)(gong)(gong)技術(shu)，既保證了(le)(le)壩(ba)(ba)(ba)肩開挖質(zhi)量(liang)，又加(jia)快了(le)(le)施(shi)(shi)工(gong)(gong)(gong)進度。在(zai)(zai)上游圍(wei)(wei)堰(yan)孤石、漂石密集、高(gao)(gao)落(luo)差、水(shui)流急、防(fang)滲困難的(de)情況下(xia)，采(cai)用(yong)九局(ju)首(shou)創的(de)“復(fu)雜地層圍(wei)(wei)堰(yan)高(gao)(gao)效快速防(fang)滲灌漿技術(shu)”，有(you)效地解決(jue)了(le)(le)圍(wei)(wei)堰(yan)“閉氣”施(shi)(shi)工(gong)(gong)(gong)難題。針對大壩(ba)(ba)(ba)右岸(an)(an)施(shi)(shi)工(gong)(gong)(gong)無交通(tong)的(de)實際，設計(ji)了(le)(le)10噸臨(lin)時走線和(he)右壩(ba)(ba)(ba)肩兩跨長23米(mi)的(de)鋼棧橋(qiao)，解決(jue)了(le)(le)右岸(an)(an)開挖和(he)澆(jiao)筑(zhu)通(tong)道及大壩(ba)(ba)(ba)材(cai)料(liao)運(yun)輸(shu)難題。在(zai)(zai)大壩(ba)(ba)(ba)左岸(an)(an)自然災害蹦塌高(gao)(gao)邊坡治(zhi)理中(zhong)(zhong)(zhong)(zhong)和(he)壩(ba)(ba)(ba)頂(ding)至(zhi)進水(shui)塔交通(tong)橋(qiao)施(shi)(shi)工(gong)(gong)(gong)中(zhong)(zhong)(zhong)(zhong)，設計(ji)附壁懸空(kong)腳手(shou)架方案，節約(yue)了(le)(le)施(shi)(shi)工(gong)(gong)(gong)成本，加(jia)快了(le)(le)施(shi)(shi)工(gong)(gong)(gong)進度。特別是在(zai)(zai)大壩(ba)(ba)(ba)混凝土澆(jiao)筑(zhu)過程中(zhong)(zhong)(zhong)(zhong)，采(cai)用(yong)外摻氧(yang)化鎂、全壩(ba)(ba)(ba)段實施(shi)(shi)通(tong)倉澆(jiao)筑(zhu)，工(gong)(gong)(gong)程質(zhi)量(liang)優(you)良，沒(mei)有(you)出現任何裂縫，受到有(you)關專(zhuan)家的(de)高(gao)(gao)度評(ping)價。

　　老江底水(shui)電(dian)(dian)站的建成(cheng)投產大大緩解了(le)當地缺電(dian)(dian)的緊(jin)張矛(mao)盾，拉動了(le)當地經(jing)(jing)濟的發展，使(shi)經(jing)(jing)濟社會發生了(le)巨大的變化(hua)。
