　　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(la)西(xi)瓦水(shui)(shui)電(dian)(dian)(dian)(dian)站(zhan)進(jin)(jin)水(shui)(shui)塔(ta)混凝土開工(gong)(gong)(gong)(gong)(gong)澆筑以(yi)(yi)來，中國水(shui)(shui)電(dian)(dian)(dian)(dian)三(san)局(ju)以(yi)(yi)“建電(dian)(dian)(dian)(dian)站(zhan)何(he)懼天險(xian)，創精(jing)品自有三(san)局(ju)”的高昂精(jing)神，克服了(le)(le)(le)(le)進(jin)(jin)水(shui)(shui)塔(ta)施工(gong)(gong)(gong)(gong)(gong)場地狹小、干(gan)擾大(da)(da)、入(ru)料手段緊缺(que)、工(gong)(gong)(gong)(gong)(gong)序復雜、施工(gong)(gong)(gong)(gong)(gong)難(nan)度大(da)(da)等困難(nan)，戰勝(sheng)高原缺(que)養、氣(qi)溫惡劣，澆筑混凝土25萬立方米，鋼筋安裝1.3千噸。在進(jin)(jin)水(shui)(shui)塔(ta)施工(gong)(gong)(gong)(gong)(gong)過程中，水(shui)(shui)電(dian)(dian)(dian)(dian)三(san)局(ju)采用鋼棧橋(qiao)、高排架(jia)、皮帶機配合MY-BOX溜管輸送三(san)級料垂(chui)直入(ru)倉的方案，解(jie)決了(le)(le)(le)(le)進(jin)(jin)水(shui)(shui)塔(ta)入(ru)料難(nan)的問題；采用滑模(mo)工(gong)(gong)(gong)(gong)(gong)藝，極大(da)(da)的提高了(le)(le)(le)(le)施工(gong)(gong)(gong)(gong)(gong)效(xiao)率，縮短了(le)(le)(le)(le)工(gong)(gong)(gong)(gong)(gong)期(qi)。據統(tong)計，拉(la)西(xi)瓦水(shui)(shui)電(dian)(dian)(dian)(dian)站(zhan)進(jin)(jin)水(shui)(shui)塔(ta)采用滑模(mo)工(gong)(gong)(gong)(gong)(gong)藝后(hou)，工(gong)(gong)(gong)(gong)(gong)期(qi)至(zhi)少提前7個月(yue)以(yi)(yi)上。同時，在攔污柵墩滑模(mo)施工(gong)(gong)(gong)(gong)(gong)中，在國內水(shui)(shui)電(dian)(dian)(dian)(dian)史上首創了(le)(le)(le)(le)滑模(mo)柵軌埋(mai)件一次成型的施工(gong)(gong)(gong)(gong)(gong)技術，并(bing)在埋(mai)件的加(jia)固(gu)及如何(he)保證埋(mai)件精(jing)度方面積(ji)累了(le)(le)(le)(le)豐厚的經(jing)驗，取(qu)得了(le)(le)(le)(le)良好的經(jing)濟效(xiao)益(yi)和社會效(xiao)益(yi)，為今后(hou)水(shui)(shui)電(dian)(dian)(dian)(dian)施工(gong)(gong)(gong)(gong)(gong)提供(gong)了(le)(le)(le)(le)經(jing)驗和實例，具有廣泛(fan)的應用前景。
