4月3日，葛洲壩西南工程局金安橋廠房項目部承建的金安橋水電站首臺機組（4號機）蝸殼比合同工期提前45天安裝完成，并一次性通過驗收，為機組按期發電奠定了堅實的基礎，受到業主和監理的稱贊。
金安(an)(an)橋水(shui)電站共(gong)裝(zhuang)(zhuang)4臺水(shui)輪機(ji)蝸殼，每臺機(ji)蝸殼重量為513.42噸，分34節(jie)，是(shi)機(ji)組安(an)(an)裝(zhuang)(zhuang)的(de)重點卡關項目(mu)，其進(jin)(jin)(jin)度直接影響整個(ge)機(ji)組安(an)(an)裝(zhuang)(zhuang)進(jin)(jin)(jin)度。承擔蝸殼安(an)(an)裝(zhuang)(zhuang)的(de)葛洲壩機(ji)電公司西南安(an)(an)裝(zhuang)(zhuang)處從拼裝(zhuang)(zhuang)、安(an)(an)裝(zhuang)(zhuang)到(dao)焊接，始終堅(jian)持“自檢(jian)、互(hu)檢(jian)、終檢(jian)" 的(de)三檢(jian)制, 保證每道工(gong)(gong)(gong)序過程都嚴(yan)格按技(ji)術規范進(jin)(jin)(jin)行施工(gong)(gong)(gong), 從而(er)使安(an)(an)裝(zhuang)(zhuang)質量合格率(lv)達到(dao)100%,優(you)良率(lv)達到(dao)99.8%。為了加快安(an)(an)裝(zhuang)(zhuang)進(jin)(jin)(jin)度，葛洲壩人采用網(wang)絡(luo)技(ji)術組織施工(gong)(gong)(gong), 合理(li)安(an)(an)排工(gong)(gong)(gong)力(li)，由(you)單作(zuo)業(ye)面施工(gong)(gong)(gong)調整到(dao)多作(zuo)業(ye)面施工(gong)(gong)(gong), 使趕(gan)工(gong)(gong)(gong)工(gong)(gong)(gong)期得以(yi)實現，保證了首臺機(ji)組進(jin)(jin)(jin)度要求。
