厄瓜多爾(er)當地時間6月2日，哈電(dian)(dian)集(ji)團與美(mei)納(na)斯項(xiang)(xiang)目業主CELEC SUR、監理公司HIDROJUBONES和項(xiang)(xiang)目土(tu)建移交(jiao)驗(yan)收(shou)委員會正式(shi)簽署了厄瓜多爾(er)美(mei)納(na)斯3×90MW水(shui)電(dian)(dian)項(xiang)(xiang)目土(tu)建最終(zhong)(zhong)移交(jiao)紀要，標志著美(mei)納(na)斯項(xiang)(xiang)目土(tu)建工程質保期(qi)工作圓滿完成，實現向業主的(de)最終(zhong)(zhong)移交(jiao)。至(zhi)此(ci)，美(mei)納(na)斯項(xiang)(xiang)目成為在厄瓜多爾(er)由中(zhong)資企業承建的(de)眾多大型(xing)水(shui)電(dian)(dian)項(xiang)(xiang)目中(zhong)首個也是唯一一個實現土(tu)建最終(zhong)(zhong)移交(jiao)的(de)水(shui)電(dian)(dian)站(zhan)。

美(mei)納斯項(xiang)目(mu)是“哈(ha)(ha)電(dian)(dian)(dian)(dian)(dian)(dian)配(pei)套”到“哈(ha)(ha)電(dian)(dian)(dian)(dian)(dian)(dian)制(zhi)造”的典范工程。作為由(you)中資企業承建(jian)的厄(e)瓜多(duo)(duo)爾第三大(da)水(shui)(shui)(shui)電(dian)(dian)(dian)(dian)(dian)(dian)站，美(mei)納斯水(shui)(shui)(shui)電(dian)(dian)(dian)(dian)(dian)(dian)項(xiang)目(mu)被視為厄(e)瓜多(duo)(duo)爾太平(ping)洋水(shui)(shui)(shui)系(xi)最重要(yao)的水(shui)(shui)(shui)利工程之一，將(jiang)改善、優(you)化厄(e)瓜多(duo)(duo)爾電(dian)(dian)(dian)(dian)(dian)(dian)力能(neng)源(yuan)結構，提(ti)供更多(duo)(duo)清潔(jie)能(neng)源(yuan)，推動當地(di)(di)經濟發(fa)展。項(xiang)目(mu)采用EPC總承包(bao)管(guan)理模式建(jian)設，配(pei)置3臺單機(ji)容量90MW沖擊水(shui)(shui)(shui)輪(lun)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)組, 最大(da)年發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)量將(jiang)達1.29億(yi)千瓦(wa)時。項(xiang)目(mu)主要(yao)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)設備(bei)，包(bao)括水(shui)(shui)(shui)輪(lun)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)、勵磁、調速器等系(xi)統全部由(you)哈(ha)(ha)電(dian)(dian)(dian)(dian)(dian)(dian)集團(tuan)設計、制(zhi)造和供貨，其他輔助系(xi)統設備(bei)均由(you)中國廠商制(zhi)造供貨。美(mei)納斯項(xiang)目(mu)地(di)(di)質情(qing)況(kuang)極其復雜,給項(xiang)目(mu)執行(xing)一度帶來巨大(da)挑戰。為精心打造哈(ha)(ha)電(dian)(dian)(dian)(dian)(dian)(dian)集團(tuan)在南美(mei)市場的首個水(shui)(shui)(shui)電(dian)(dian)(dian)(dian)(dian)(dian)總承包(bao)項(xiang)目(mu),樹立水(shui)(shui)(shui)電(dian)(dian)(dian)(dian)(dian)(dian)領域的標桿工程，哈(ha)(ha)電(dian)(dian)(dian)(dian)(dian)(dian)集團(tuan)國際公司克服諸多(duo)(duo)困難，在土建(jian)施工方面采取了多(duo)(duo)項(xiang)關鍵技(ji)術。

美納(na)斯項目采用全(quan)斷(duan)面反(fan)(fan)井(jing)(jing)鉆(zhan)機設備對通風(feng)電纜豎井(jing)(jing)和壓(ya)力豎井(jing)(jing)進(jin)行開(kai)挖，創下中(zhong)資企業海外首例(li)。2015年10月29日,直(zhi)徑為(wei)5.5米，深度為(wei)452米的壓(ya)力豎井(jing)(jing)全(quan)斷(duan)面反(fan)(fan)擴工(gong)(gong)作(zuo)順利(li)完成(cheng)。壓(ya)力豎井(jing)(jing)的最終偏斜(xie)精準度、全(quan)斷(duan)面反(fan)(fan)擴直(zhi)徑、深度在世界水電施(shi)工(gong)(gong)領域均處于領先水平，為(wei)哈電集團水電項目建設積累(lei)了(le)寶貴的創新性工(gong)(gong)程經驗。

美納斯項目建有78米高碾壓混凝土重力壩，是厄瓜多爾首個全碾壓混凝土大壩。2016年12月29日大壩全線貫通。

在項(xiang)目高(gao)(gao)巖(yan)石(shi)硬度(du)情況下，項(xiang)目部采用TBM(隧(sui)道掘進(jin)(jin)機)對14公里引水隧(sui)洞進(jin)(jin)行開(kai)挖。2017年(nian)3月21日,引水隧(sui)洞TBM段的(de)全線精準貫通(tong), 開(kai)啟(qi)了哈電集(ji)團在TBM隧(sui)洞開(kai)挖管理方面(mian)的(de)新篇(pian)章(zhang)，對未來開(kai)拓國際(ji)高(gao)(gao)端總承包市場增添了一把(ba)意(yi)義非凡的(de)“金(jin)鑰(yao)匙”。

2018年8月27日，9根230kV高壓電纜在直徑6米、深440米通風電纜井下敷設完成，創下中厄兩國最深豎井高壓電纜敷設紀錄，成為國際上較少掌握該技術的企業之一。

自2019年9月項目臨時(shi)移交以(yi)來，美納(na)斯項目團隊積(ji)(ji)極(ji)克服各種不利影響因(yin)素，尤其在全(quan)球疫(yi)情蔓延下，仍全(quan)力(li)協調現場各方積(ji)(ji)極(ji)開展土建(jian)消(xiao)缺(que)及機組(zu)檢修工作，確保(bao)了(le)土建(jian)工程全(quan)部按(an)期履約，實力(li)詮釋哈電集團疫(yi)情防控(kong)的(de)落實落地和(he)項目管(guan)理的(de)高質高效。
