　　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(lao)江(jiang)底水電(dian)站位于貴州省南(nan)盤江(jiang)一級支(zhi)流黃泥(ni)河(he)上，總裝機10萬千(qian)瓦(wa)，為三等中型電(dian)站，首部樞紐永久性(xing)主(zhu)要水工建(jian)筑(zhu)物(wu)有攔河(he)大(da)壩(ba)、岸邊溢洪道、泄洪洞、引(yin)水系統及發電(dian)廠房等建(jian)筑(zhu)物(wu)。攔河(he)大(da)壩(ba)設計為橢圓雙(shuang)曲薄拱壩(ba)，最(zui)大(da)壩(ba)高(gao)為75米，年平(ping)均發電(dian)量４·１８２億千(qian)瓦(wa)時(shi)。

　　該工(gong)(gong)(gong)(gong)程于2005年6月10日(ri)開工(gong)(gong)(gong)(gong)，施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)中(zhong)(zhong)，中(zhong)(zhong)國水(shui)電九(jiu)局針(zhen)對(dui)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)場面十分狹窄、多處交(jiao)(jiao)(jiao)叉作業、技術含量高(gao)、施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)難(nan)(nan)度大(da)、施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)周期短等特(te)點，加(jia)(jia)大(da)科技攻關力(li)度，積極推廣應用(yong)新技術、新工(gong)(gong)(gong)(gong)藝(yi)和(he)新材料，不斷提高(gao)項目部施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)水(shui)平。在兩壩肩(jian)高(gao)邊(bian)坡開挖(wa)中(zhong)(zhong)，采(cai)用(yong)深孔(kong)預(yu)裂(lie)爆破(po)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)技術，既保證(zheng)了壩肩(jian)開挖(wa)質(zhi)量，又加(jia)(jia)快(kuai)了施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)進(jin)度。在上游圍堰(yan)孤石、漂石密集、高(gao)落(luo)差、水(shui)流急、防滲(shen)困難(nan)(nan)的(de)(de)情況下，采(cai)用(yong)九(jiu)局首創(chuang)的(de)(de)“復雜地(di)(di)層(ceng)圍堰(yan)高(gao)效快(kuai)速防滲(shen)灌漿技術”，有(you)效地(di)(di)解決了圍堰(yan)“閉氣”施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)難(nan)(nan)題(ti)(ti)。針(zhen)對(dui)大(da)壩右岸施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)無交(jiao)(jiao)(jiao)通(tong)的(de)(de)實際，設計了10噸(dun)臨時走(zou)線和(he)右壩肩(jian)兩跨長23米(mi)的(de)(de)鋼棧橋(qiao)，解決了右岸開挖(wa)和(he)澆筑(zhu)通(tong)道及大(da)壩材料運輸(shu)難(nan)(nan)題(ti)(ti)。在大(da)壩左岸自然災(zai)害蹦塌(ta)高(gao)邊(bian)坡治(zhi)理中(zhong)(zhong)和(he)壩頂至進(jin)水(shui)塔交(jiao)(jiao)(jiao)通(tong)橋(qiao)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)中(zhong)(zhong)，設計附壁懸空(kong)腳(jiao)手架(jia)方案，節(jie)約了施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)成本，加(jia)(jia)快(kuai)了施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)進(jin)度。特(te)別是在大(da)壩混凝土(tu)澆筑(zhu)過程中(zhong)(zhong)，采(cai)用(yong)外摻(chan)氧化鎂、全(quan)壩段實施(shi)(shi)(shi)(shi)通(tong)倉澆筑(zhu)，工(gong)(gong)(gong)(gong)程質(zhi)量優(you)良，沒有(you)出(chu)現任(ren)何(he)裂(lie)縫，受(shou)到有(you)關專家(jia)的(de)(de)高(gao)度評價。

　　老(lao)江底水電站(zhan)的建成投產大(da)(da)大(da)(da)緩(huan)解了當地(di)缺電的緊張矛盾，拉動了當地(di)經濟(ji)的發展，使經濟(ji)社會發生了巨大(da)(da)的變化。
