日前，由中國水電集團水電三局有限公司承建的拉西瓦水電站進水塔主體一期混凝土澆筑圓滿結束，為拉西瓦水電站實現下閘蓄水目標打下了堅實的基礎。
自2006年3月(yue)(yue)28日拉西(xi)瓦(wa)水(shui)電站(zhan)進(jin)(jin)水(shui)塔混凝土開工(gong)(gong)(gong)(gong)(gong)澆筑(zhu)以來，中(zhong)國(guo)水(shui)電三(san)(san)局以“建電站(zhan)何懼天險，創(chuang)(chuang)精(jing)品自有(you)三(san)(san)局”的(de)(de)(de)高昂精(jing)神，克(ke)服了(le)(le)進(jin)(jin)水(shui)塔施(shi)工(gong)(gong)(gong)(gong)(gong)場(chang)地(di)狹小、干(gan)擾大、入料手段緊缺、工(gong)(gong)(gong)(gong)(gong)序復雜、施(shi)工(gong)(gong)(gong)(gong)(gong)難度(du)大等(deng)困難，戰勝高原缺養、氣溫惡劣，澆筑(zhu)混凝土25萬立方米，鋼筋安裝1.3千噸。在進(jin)(jin)水(shui)塔施(shi)工(gong)(gong)(gong)(gong)(gong)過(guo)程(cheng)中(zhong)，水(shui)電三(san)(san)局采(cai)用鋼棧橋、高排架(jia)、皮帶機配(pei)合MY-BOX溜管輸(shu)送三(san)(san)級料垂直(zhi)入倉(cang)的(de)(de)(de)方案，解決(jue)了(le)(le)進(jin)(jin)水(shui)塔入料難的(de)(de)(de)問題(ti)；采(cai)用滑模(mo)工(gong)(gong)(gong)(gong)(gong)藝，極大的(de)(de)(de)提(ti)高了(le)(le)施(shi)工(gong)(gong)(gong)(gong)(gong)效(xiao)率，縮短了(le)(le)工(gong)(gong)(gong)(gong)(gong)期。據(ju)統(tong)計，拉西(xi)瓦(wa)水(shui)電站(zhan)進(jin)(jin)水(shui)塔采(cai)用滑模(mo)工(gong)(gong)(gong)(gong)(gong)藝后(hou)，工(gong)(gong)(gong)(gong)(gong)期至少提(ti)前(qian)7個月(yue)(yue)以上。同時(shi)，在攔(lan)污柵墩滑模(mo)施(shi)工(gong)(gong)(gong)(gong)(gong)中(zhong)，在國(guo)內水(shui)電史上首(shou)創(chuang)(chuang)了(le)(le)滑模(mo)柵軌埋件(jian)一次成型的(de)(de)(de)施(shi)工(gong)(gong)(gong)(gong)(gong)技術，并在埋件(jian)的(de)(de)(de)加固及如(ru)何保(bao)證(zheng)埋件(jian)精(jing)度(du)方面積(ji)累了(le)(le)豐厚的(de)(de)(de)經(jing)驗(yan)，取得了(le)(le)良好的(de)(de)(de)經(jing)濟(ji)效(xiao)益(yi)(yi)和社會效(xiao)益(yi)(yi)，為今后(hou)水(shui)電施(shi)工(gong)(gong)(gong)(gong)(gong)提(ti)供了(le)(le)經(jing)驗(yan)和實(shi)例，具有(you)廣(guang)泛的(de)(de)(de)應(ying)用前(qian)景。
