日前，由中國水電集團水電十四局承建的緬甸瑞麗江一級水電站大壩3號壩段順利澆筑到高程735米，標志著大壩混凝土澆筑全面封頂。
瑞麗江(jiang)一級水電站(zhan)(zhan)大(da)壩(ba)(ba)(ba)(ba)是混(hun)凝(ning)(ning)土重(zhong)(zhong)力(li)壩(ba)(ba)(ba)(ba)，其中(zhong)(zhong)2、3、4號壩(ba)(ba)(ba)(ba)段(duan)長(chang)44米(mi)，為溢流壩(ba)(ba)(ba)(ba)段(duan)；1、5、6、7號壩(ba)(ba)(ba)(ba)段(duan)長(chang)143.65米(mi)，為非溢流壩(ba)(ba)(ba)(ba)段(duan)；壩(ba)(ba)(ba)(ba)頂寬6米(mi)，壩(ba)(ba)(ba)(ba)高47米(mi)。瑞麗江(jiang)一級水電站(zhan)(zhan)是一個(ge)典型的(de)(de)“三(san)邊(bian)”（邊(bian)設(she)(she)計(ji)、邊(bian)施(shi)(shi)工(gong)(gong)(gong)、邊(bian)修改）工(gong)(gong)(gong)程(cheng)，大(da)壩(ba)(ba)(ba)(ba)在施(shi)(shi)工(gong)(gong)(gong)過程(cheng)中(zhong)(zhong)設(she)(she)計(ji)方(fang)案曾(ceng)多次(ci)(ci)變更，水泥、鋼材(cai)等物資材(cai)料的(de)(de)供應在澆(jiao)筑過程(cheng)中(zhong)(zhong)曾(ceng)數次(ci)(ci)中(zhong)(zhong)斷(duan)，使本來(lai)就十(shi)分緊張的(de)(de)工(gong)(gong)(gong)期(qi)更加嚴峻。但是項目(mu)部精心組(zu)織，科學(xue)施(shi)(shi)工(gong)(gong)(gong)。由于(yu)工(gong)(gong)(gong)作面較多，一臺(tai)布(bu)料機無法滿足混(hun)凝(ning)(ning)土澆(jiao)筑的(de)(de)需要，重(zhong)(zhong)機隊就組(zu)織技(ji)術(shu)攻關，自主(zhu)研制(zhi)了(le)功(gong)率(lv)小、自重(zhong)(zhong)輕、送料能力(li)強、能輸(shu)送各種配合(he)比(bi)混(hun)凝(ning)(ning)土的(de)(de)皮帶輸(shu)送機，用于(yu)大(da)壩(ba)(ba)(ba)(ba)混(hun)凝(ning)(ning)土澆(jiao)筑，解決了(le)混(hun)凝(ning)(ning)土入倉設(she)(she)備不足的(de)(de)問(wen)題，極大(da)地(di)緩解了(le)壓力(li)。
