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日拉西瓦水(shui)(shui)電(dian)站進(jin)水(shui)(shui)塔(ta)混(hun)凝土開工(gong)(gong)(gong)(gong)澆(jiao)筑(zhu)以來，中(zhong)國(guo)水(shui)(shui)電(dian)三局以“建電(dian)站何懼天險，創(chuang)精品自有(you)(you)三局”的(de)(de)高(gao)(gao)昂精神(shen)，克(ke)服了(le)進(jin)水(shui)(shui)塔(ta)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)場地狹小、干(gan)擾大(da)、入(ru)料手(shou)段緊缺(que)、工(gong)(gong)(gong)(gong)序復雜、施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)難度(du)大(da)等困難，戰勝高(gao)(gao)原(yuan)缺(que)養、氣溫惡劣(lie)，澆(jiao)筑(zhu)混(hun)凝土25萬立方米(mi)，鋼筋安裝1.3千噸(dun)。在(zai)進(jin)水(shui)(shui)塔(ta)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)過程中(zhong)，水(shui)(shui)電(dian)三局采用鋼棧橋、高(gao)(gao)排(pai)架、皮帶機配合MY-BOX溜管輸送三級料垂直入(ru)倉的(de)(de)方案(an)，解決了(le)進(jin)水(shui)(shui)塔(ta)入(ru)料難的(de)(de)問題；采用滑模工(gong)(gong)(gong)(gong)藝，極大(da)的(de)(de)提高(gao)(gao)了(le)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)效率，縮短(duan)了(le)工(gong)(gong)(gong)(gong)期(qi)。據統計，拉西瓦水(shui)(shui)電(dian)站進(jin)水(shui)(shui)塔(ta)采用滑模工(gong)(gong)(gong)(gong)藝后(hou)，工(gong)(gong)(gong)(gong)期(qi)至少提前(qian)(qian)7個月以上。同(tong)時(shi)，在(zai)攔污柵墩滑模施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)中(zhong)，在(zai)國(guo)內水(shui)(shui)電(dian)史上首創(chuang)了(le)滑模柵軌(gui)埋(mai)件(jian)一次(ci)成型的(de)(de)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)技術，并在(zai)埋(mai)件(jian)的(de)(de)加固及如何保證埋(mai)件(jian)精度(du)方面(mian)積累了(le)豐厚(hou)的(de)(de)經驗，取得了(le)良(liang)好的(de)(de)經濟效益(yi)和社會(hui)效益(yi)，為今后(hou)水(shui)(shui)電(dian)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)提供了(le)經驗和實例，具有(you)(you)廣(guang)泛的(de)(de)應用前(qian)(qian)景。
