由葛洲壩集團基礎公司承(cheng)擔施工的四川大渡河瀘定水(shui)電站2號、3號泄洪洞(dong)出(chu)口(kou)圍(wei)堰(yan)懸掛式混凝土防滲墻工程于(yu)5月31日提前完工。
四川瀘定水電站位于大渡河瀘定縣城上游2-3公里處，裝機84萬千瓦。工程總投資669642萬元。此次進行施工的2、3號泄洪洞出口圍堰懸掛式混凝土防滲墻工程，施工圍堰軸線長約367米，平均墻深27米，墻厚80厘米，設計工程量為10080平方米，工期要求55天完成。
葛(ge)洲(zhou)壩(ba)集(ji)團基礎公(gong)司于3月底組織精兵強(qiang)將及37臺(tai)套施工(gong)(gong)(gong)(gong)(gong)(gong)設備(bei)奔赴(fu)大(da)渡(du)(du)河瀘定(ding)水電站(zhan)，投入該項目混凝土防(fang)滲墻(qiang)施工(gong)(gong)(gong)(gong)(gong)(gong)。該工(gong)(gong)(gong)(gong)(gong)(gong)程于4月12日(ri)在(zai)220米軸線上(shang)先(xian)期開(kai)工(gong)(gong)(gong)(gong)(gong)(gong)，5月12日(ri)軸線全(quan)面施工(gong)(gong)(gong)(gong)(gong)(gong)。因距大(da)渡(du)(du)河較近，受大(da)渡(du)(du)河水位漲落頻繁影(ying)響，對造孔(kong)槽段坍塌(ta)產生了(le)較大(da)的風險；為(wei)防(fang)止造孔(kong)槽段坍塌(ta)，搶工(gong)(gong)(gong)(gong)(gong)(gong)期、提高形象(xiang)進度(du)，施工(gong)(gong)(gong)(gong)(gong)(gong)中，葛(ge)洲(zhou)壩(ba)人克難攻(gong)堅(jian)，拼搏進取，精心組織施工(gong)(gong)(gong)(gong)(gong)(gong)，根據(ju)工(gong)(gong)(gong)(gong)(gong)(gong)程地質實際情況，在(zai)施工(gong)(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)(gong)藝上(shang)采用了(le)“平(ping)打法(fa)(fa)”、“孔(kong)口回漿法(fa)(fa)”，強(qiang)化(hua)了(le)現場(chang)質量、安全(quan)、文明(ming)施工(gong)(gong)(gong)(gong)(gong)(gong)管理，使施工(gong)(gong)(gong)(gong)(gong)(gong)效益(yi)大(da)幅提高，推進了(le)工(gong)(gong)(gong)(gong)(gong)(gong)程施工(gong)(gong)(gong)(gong)(gong)(gong)的順利進行(xing)。
經過50天(tian)晝夜奮戰(zhan)，比計劃工期(qi)提前了5天(tian)完工，實(shi)現了質(zhi)量(liang)、安全零事故目標，得到華(hua)電業主、中南監理的高度(du)贊譽。
