由葛洲壩集團基礎公司承擔施工的四川大渡(du)河瀘定水電站2號、3號泄洪(hong)洞出口圍(wei)堰懸掛式混凝土防滲墻工程于5月31日提前(qian)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)洲壩(ba)(ba)集團(tuan)基礎公司于3月(yue)底(di)組織精兵強將及37臺套施(shi)(shi)工(gong)(gong)(gong)設備奔(ben)赴大渡河(he)瀘定(ding)水電(dian)站，投(tou)入該(gai)項目混凝土防滲墻(qiang)施(shi)(shi)工(gong)(gong)(gong)。該(gai)工(gong)(gong)(gong)程(cheng)于4月(yue)12日在220米(mi)軸線上先(xian)期開工(gong)(gong)(gong)，5月(yue)12日軸線全面施(shi)(shi)工(gong)(gong)(gong)。因距大渡河(he)較近，受大渡河(he)水位漲落頻繁影響(xiang)，對造(zao)孔(kong)槽段(duan)坍塌產生了(le)較大的風(feng)險；為防止造(zao)孔(kong)槽段(duan)坍塌，搶工(gong)(gong)(gong)期、提(ti)高形象進(jin)度，施(shi)(shi)工(gong)(gong)(gong)中(zhong)，葛(ge)洲壩(ba)(ba)人克難攻堅，拼搏進(jin)取，精心組織施(shi)(shi)工(gong)(gong)(gong)，根據工(gong)(gong)(gong)程(cheng)地質(zhi)實際(ji)情況，在施(shi)(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝上采(cai)用了(le)“平打法”、“孔(kong)口回漿(jiang)法”，強化了(le)現場質(zhi)量、安全、文明施(shi)(shi)工(gong)(gong)(gong)管理(li)，使施(shi)(shi)工(gong)(gong)(gong)效益(yi)大幅(fu)提(ti)高，推進(jin)了(le)工(gong)(gong)(gong)程(cheng)施(shi)(shi)工(gong)(gong)(gong)的順利進(jin)行。
經(jing)過(guo)50天(tian)晝夜奮戰(zhan)，比計(ji)劃工期提前(qian)了5天(tian)完(wan)工，實現了質(zhi)量、安全零事故(gu)目標，得到華(hua)電業主、中南(nan)監理的高度(du)贊譽。
