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)28日拉西瓦水(shui)電(dian)(dian)(dian)站(zhan)進水(shui)塔混(hun)凝(ning)土開(kai)工(gong)(gong)(gong)(gong)澆筑以(yi)來，中(zhong)(zhong)國(guo)(guo)水(shui)電(dian)(dian)(dian)三(san)局以(yi)“建(jian)電(dian)(dian)(dian)站(zhan)何(he)懼天險，創精品自有(you)三(san)局”的(de)(de)(de)高(gao)(gao)昂精神，克服了(le)(le)(le)(le)進水(shui)塔施(shi)(shi)工(gong)(gong)(gong)(gong)場地狹(xia)小、干(gan)擾大(da)(da)(da)、入料(liao)手(shou)段緊缺(que)、工(gong)(gong)(gong)(gong)序復雜、施(shi)(shi)工(gong)(gong)(gong)(gong)難度(du)大(da)(da)(da)等困(kun)難，戰(zhan)勝高(gao)(gao)原(yuan)缺(que)養、氣溫惡劣，澆筑混(hun)凝(ning)土25萬立方(fang)米(mi)，鋼筋安(an)裝1.3千噸。在(zai)(zai)進水(shui)塔施(shi)(shi)工(gong)(gong)(gong)(gong)過(guo)程中(zhong)(zhong)，水(shui)電(dian)(dian)(dian)三(san)局采用(yong)鋼棧橋、高(gao)(gao)排架、皮(pi)帶機配(pei)合MY-BOX溜(liu)管輸送三(san)級料(liao)垂直(zhi)入倉的(de)(de)(de)方(fang)案，解決了(le)(le)(le)(le)進水(shui)塔入料(liao)難的(de)(de)(de)問(wen)題；采用(yong)滑模(mo)工(gong)(gong)(gong)(gong)藝，極(ji)大(da)(da)(da)的(de)(de)(de)提高(gao)(gao)了(le)(le)(le)(le)施(shi)(shi)工(gong)(gong)(gong)(gong)效(xiao)率，縮短了(le)(le)(le)(le)工(gong)(gong)(gong)(gong)期。據統計，拉西瓦水(shui)電(dian)(dian)(dian)站(zhan)進水(shui)塔采用(yong)滑模(mo)工(gong)(gong)(gong)(gong)藝后(hou)，工(gong)(gong)(gong)(gong)期至少提前7個月(yue)以(yi)上(shang)。同時(shi)，在(zai)(zai)攔污柵墩滑模(mo)施(shi)(shi)工(gong)(gong)(gong)(gong)中(zhong)(zhong)，在(zai)(zai)國(guo)(guo)內水(shui)電(dian)(dian)(dian)史上(shang)首創了(le)(le)(le)(le)滑模(mo)柵軌埋件一次(ci)成型(xing)的(de)(de)(de)施(shi)(shi)工(gong)(gong)(gong)(gong)技術，并在(zai)(zai)埋件的(de)(de)(de)加固及如何(he)保證埋件精度(du)方(fang)面積累了(le)(le)(le)(le)豐(feng)厚的(de)(de)(de)經(jing)驗(yan)(yan)，取得了(le)(le)(le)(le)良好(hao)的(de)(de)(de)經(jing)濟(ji)效(xiao)益(yi)和(he)社會效(xiao)益(yi)，為今(jin)后(hou)水(shui)電(dian)(dian)(dian)施(shi)(shi)工(gong)(gong)(gong)(gong)提供了(le)(le)(le)(le)經(jing)驗(yan)(yan)和(he)實例，具有(you)廣泛的(de)(de)(de)應用(yong)前景。
