　　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)電(dian)(dian)站位于貴州(zhou)省(sheng)南盤江一級支流(liu)黃泥河(he)(he)上，總裝機10萬千(qian)瓦，為(wei)三等(deng)中(zhong)型電(dian)(dian)站，首部樞紐永久性主要水(shui)工建筑(zhu)物有攔(lan)河(he)(he)大壩、岸邊溢(yi)洪道、泄洪洞、引水(shui)系統及發電(dian)(dian)廠(chang)房等(deng)建筑(zhu)物。攔(lan)河(he)(he)大壩設計為(wei)橢圓雙曲薄拱壩，最大壩高為(wei)75米，年平均發電(dian)(dian)量(liang)４·１８２億千(qian)瓦時。

　　該工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)于2005年(nian)6月10日(ri)開(kai)工(gong)(gong)(gong)(gong)(gong)(gong)，施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)中(zhong)，中(zhong)國水(shui)電(dian)九局(ju)針對施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)場面十分狹窄、多處交叉作業、技(ji)術(shu)(shu)含量(liang)高(gao)(gao)、施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)難(nan)度(du)大(da)、施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)周期(qi)短等特點，加大(da)科(ke)技(ji)攻關力度(du)，積極推廣應用新技(ji)術(shu)(shu)、新工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)和新材料(liao)，不斷提高(gao)(gao)項目部施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)水(shui)平(ping)。在(zai)兩(liang)壩(ba)(ba)(ba)肩高(gao)(gao)邊坡開(kai)挖中(zhong)，采用深(shen)孔預(yu)裂爆破(po)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)技(ji)術(shu)(shu)，既(ji)保證了(le)(le)壩(ba)(ba)(ba)肩開(kai)挖質量(liang)，又加快了(le)(le)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)進度(du)。在(zai)上游圍堰孤石(shi)、漂石(shi)密集、高(gao)(gao)落(luo)差、水(shui)流急、防滲困難(nan)的(de)情(qing)況下，采用九局(ju)首創的(de)“復雜地層圍堰高(gao)(gao)效快速防滲灌(guan)漿技(ji)術(shu)(shu)”，有效地解(jie)決(jue)了(le)(le)圍堰“閉(bi)氣”施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)難(nan)題。針對大(da)壩(ba)(ba)(ba)右(you)(you)岸(an)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)無(wu)交通的(de)實際，設計(ji)了(le)(le)10噸(dun)臨時走線和右(you)(you)壩(ba)(ba)(ba)肩兩(liang)跨(kua)長23米的(de)鋼棧(zhan)橋，解(jie)決(jue)了(le)(le)右(you)(you)岸(an)開(kai)挖和澆筑通道及大(da)壩(ba)(ba)(ba)材料(liao)運輸難(nan)題。在(zai)大(da)壩(ba)(ba)(ba)左岸(an)自然(ran)災害蹦(beng)塌高(gao)(gao)邊坡治(zhi)理中(zhong)和壩(ba)(ba)(ba)頂至進水(shui)塔交通橋施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)中(zhong)，設計(ji)附壁懸空(kong)腳手架方案，節約(yue)了(le)(le)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)成本，加快了(le)(le)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)(gong)進度(du)。特別(bie)是在(zai)大(da)壩(ba)(ba)(ba)混(hun)凝土澆筑過程(cheng)中(zhong)，采用外(wai)摻(chan)氧化(hua)鎂、全壩(ba)(ba)(ba)段實施(shi)(shi)(shi)(shi)通倉(cang)澆筑，工(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)質量(liang)優(you)良，沒有出現任何裂縫，受到有關專家的(de)高(gao)(gao)度(du)評價。

　　老(lao)江底水(shui)電站的(de)建成(cheng)投產大大緩解(jie)了(le)當地缺電的(de)緊(jin)張矛盾，拉動了(le)當地經濟(ji)的(de)發展(zhan)，使經濟(ji)社(she)會發生了(le)巨大的(de)變(bian)化。
