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28日拉西(xi)瓦(wa)水(shui)電站(zhan)(zhan)進(jin)(jin)水(shui)塔混凝土開工(gong)(gong)(gong)澆筑以(yi)(yi)來，中(zhong)國水(shui)電三(san)(san)局以(yi)(yi)“建電站(zhan)(zhan)何懼(ju)天險，創(chuang)精品自有(you)三(san)(san)局”的高(gao)昂精神，克服了進(jin)(jin)水(shui)塔施(shi)工(gong)(gong)(gong)場(chang)地(di)狹小、干擾大、入(ru)料手段(duan)緊缺(que)、工(gong)(gong)(gong)序復雜、施(shi)工(gong)(gong)(gong)難(nan)度大等困難(nan)，戰勝高(gao)原缺(que)養、氣溫惡劣，澆筑混凝土25萬立方米，鋼筋安裝(zhuang)1.3千噸(dun)。在(zai)進(jin)(jin)水(shui)塔施(shi)工(gong)(gong)(gong)過程中(zhong)，水(shui)電三(san)(san)局采(cai)用鋼棧橋、高(gao)排架、皮帶機配合MY-BOX溜管(guan)輸送(song)三(san)(san)級料垂直入(ru)倉的方案(an)，解決了進(jin)(jin)水(shui)塔入(ru)料難(nan)的問題；采(cai)用滑模(mo)(mo)工(gong)(gong)(gong)藝，極(ji)大的提(ti)高(gao)了施(shi)工(gong)(gong)(gong)效(xiao)率，縮(suo)短了工(gong)(gong)(gong)期(qi)。據統計(ji)，拉西(xi)瓦(wa)水(shui)電站(zhan)(zhan)進(jin)(jin)水(shui)塔采(cai)用滑模(mo)(mo)工(gong)(gong)(gong)藝后，工(gong)(gong)(gong)期(qi)至少提(ti)前7個月以(yi)(yi)上。同時，在(zai)攔污柵墩滑模(mo)(mo)施(shi)工(gong)(gong)(gong)中(zhong)，在(zai)國內(nei)水(shui)電史上首創(chuang)了滑模(mo)(mo)柵軌埋(mai)件(jian)一次成(cheng)型(xing)的施(shi)工(gong)(gong)(gong)技術(shu)，并在(zai)埋(mai)件(jian)的加固(gu)及如何保證埋(mai)件(jian)精度方面積累(lei)了豐厚(hou)的經驗(yan)，取得(de)了良(liang)好的經濟效(xiao)益(yi)和社(she)會效(xiao)益(yi)，為今后水(shui)電施(shi)工(gong)(gong)(gong)提(ti)供了經驗(yan)和實(shi)例，具有(you)廣泛的應(ying)用前景。
