　　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)江底水(shui)(shui)電(dian)(dian)站位于(yu)貴州省南盤江一(yi)級支流黃泥(ni)河(he)上(shang)，總裝機(ji)10萬千瓦，為(wei)三等中型電(dian)(dian)站，首部樞紐永久性(xing)主(zhu)要水(shui)(shui)工建(jian)筑(zhu)物有攔河(he)大壩、岸邊(bian)溢洪道(dao)、泄洪洞、引水(shui)(shui)系統(tong)及發電(dian)(dian)廠(chang)房(fang)等建(jian)筑(zhu)物。攔河(he)大壩設計為(wei)橢(tuo)圓(yuan)雙曲薄拱壩，最大壩高為(wei)75米(mi)，年平均(jun)發電(dian)(dian)量４·１８２億千瓦時。

　　該工(gong)(gong)(gong)程(cheng)(cheng)于2005年6月10日開(kai)工(gong)(gong)(gong)，施(shi)(shi)(shi)工(gong)(gong)(gong)中，中國水電九局(ju)針(zhen)對施(shi)(shi)(shi)工(gong)(gong)(gong)場面(mian)十(shi)分狹窄、多處(chu)交(jiao)(jiao)叉(cha)作(zuo)業、技術含量(liang)高(gao)、施(shi)(shi)(shi)工(gong)(gong)(gong)難(nan)度(du)大、施(shi)(shi)(shi)工(gong)(gong)(gong)周期(qi)短等特點，加(jia)大科技攻關(guan)力(li)度(du)，積(ji)極推廣應用(yong)新(xin)技術、新(xin)工(gong)(gong)(gong)藝和新(xin)材料，不斷提(ti)高(gao)項(xiang)目部施(shi)(shi)(shi)工(gong)(gong)(gong)水平。在兩壩(ba)肩(jian)(jian)高(gao)邊坡開(kai)挖中，采用(yong)深孔預裂爆破施(shi)(shi)(shi)工(gong)(gong)(gong)技術，既保證了(le)(le)(le)壩(ba)肩(jian)(jian)開(kai)挖質量(liang)，又(you)加(jia)快(kuai)了(le)(le)(le)施(shi)(shi)(shi)工(gong)(gong)(gong)進度(du)。在上(shang)游(you)圍(wei)堰孤(gu)石、漂(piao)石密集、高(gao)落差、水流急、防滲困難(nan)的(de)(de)情況下，采用(yong)九局(ju)首創的(de)(de)“復雜地(di)層圍(wei)堰高(gao)效快(kuai)速(su)防滲灌漿技術”，有效地(di)解(jie)決了(le)(le)(le)圍(wei)堰“閉氣”施(shi)(shi)(shi)工(gong)(gong)(gong)難(nan)題。針(zhen)對大壩(ba)右(you)岸(an)施(shi)(shi)(shi)工(gong)(gong)(gong)無交(jiao)(jiao)通(tong)(tong)的(de)(de)實(shi)際，設計(ji)了(le)(le)(le)10噸臨時走線(xian)和右(you)壩(ba)肩(jian)(jian)兩跨長23米(mi)的(de)(de)鋼(gang)棧橋(qiao)，解(jie)決了(le)(le)(le)右(you)岸(an)開(kai)挖和澆(jiao)筑通(tong)(tong)道及大壩(ba)材料運輸難(nan)題。在大壩(ba)左岸(an)自然災害蹦塌高(gao)邊坡治(zhi)理(li)中和壩(ba)頂(ding)至進水塔(ta)交(jiao)(jiao)通(tong)(tong)橋(qiao)施(shi)(shi)(shi)工(gong)(gong)(gong)中，設計(ji)附壁懸(xuan)空腳手架方案，節約了(le)(le)(le)施(shi)(shi)(shi)工(gong)(gong)(gong)成(cheng)本，加(jia)快(kuai)了(le)(le)(le)施(shi)(shi)(shi)工(gong)(gong)(gong)進度(du)。特別是在大壩(ba)混凝土(tu)澆(jiao)筑過程(cheng)(cheng)中，采用(yong)外摻(chan)氧化鎂(mei)、全(quan)壩(ba)段實(shi)施(shi)(shi)(shi)通(tong)(tong)倉澆(jiao)筑，工(gong)(gong)(gong)程(cheng)(cheng)質量(liang)優(you)良，沒有出現任何(he)裂縫(feng)，受(shou)到有關(guan)專(zhuan)家的(de)(de)高(gao)度(du)評價。

　　老(lao)江底水(shui)電(dian)站的(de)建成投產大大緩解了當地缺電(dian)的(de)緊張矛盾(dun)，拉(la)動了當地經濟(ji)的(de)發展，使經濟(ji)社會發生了巨大的(de)變化。
