厄瓜多爾當地(di)時間6月2日，哈電(dian)集團(tuan)與美(mei)納斯(si)項(xiang)目(mu)(mu)業(ye)主CELEC SUR、監理公司HIDROJUBONES和(he)項(xiang)目(mu)(mu)土(tu)建移交(jiao)(jiao)驗(yan)收委員(yuan)會正式簽署了厄瓜多爾美(mei)納斯(si)3×90MW水電(dian)項(xiang)目(mu)(mu)土(tu)建最(zui)(zui)終移交(jiao)(jiao)紀要，標志著(zhu)美(mei)納斯(si)項(xiang)目(mu)(mu)土(tu)建工程質保期(qi)工作圓滿完成，實(shi)現(xian)向業(ye)主的(de)最(zui)(zui)終移交(jiao)(jiao)。至此，美(mei)納斯(si)項(xiang)目(mu)(mu)成為在厄瓜多爾由中(zhong)資企業(ye)承建的(de)眾多大型水電(dian)項(xiang)目(mu)(mu)中(zhong)首個(ge)也是唯一一個(ge)實(shi)現(xian)土(tu)建最(zui)(zui)終移交(jiao)(jiao)的(de)水電(dian)站。

美(mei)納(na)斯(si)(si)項(xiang)(xiang)(xiang)目(mu)是(shi)“哈(ha)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)配套(tao)”到(dao)“哈(ha)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)制(zhi)造”的(de)典(dian)范工(gong)程。作(zuo)為(wei)由(you)中(zhong)資企業承(cheng)建的(de)厄瓜(gua)多(duo)爾第三大水(shui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)站，美(mei)納(na)斯(si)(si)水(shui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)項(xiang)(xiang)(xiang)目(mu)被視為(wei)厄瓜(gua)多(duo)爾太平洋(yang)水(shui)系最(zui)(zui)重要(yao)的(de)水(shui)利工(gong)程之一，將改善、優(you)化厄瓜(gua)多(duo)爾電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力能源結(jie)構，提供更多(duo)清(qing)潔(jie)能源，推動當(dang)地(di)經濟發展。項(xiang)(xiang)(xiang)目(mu)采用EPC總(zong)承(cheng)包管理模式建設，配置3臺單(dan)機(ji)容量90MW沖(chong)擊(ji)水(shui)輪發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)組(zu), 最(zui)(zui)大年發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量將達1.29億千瓦時。項(xiang)(xiang)(xiang)目(mu)主要(yao)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)設備(bei)，包括水(shui)輪發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)、勵(li)磁、調速(su)器(qi)等(deng)系統全部由(you)哈(ha)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)集團設計、制(zhi)造和供貨(huo)，其他輔助系統設備(bei)均由(you)中(zhong)國廠商制(zhi)造供貨(huo)。美(mei)納(na)斯(si)(si)項(xiang)(xiang)(xiang)目(mu)地(di)質情(qing)況極其復雜,給項(xiang)(xiang)(xiang)目(mu)執行(xing)一度帶(dai)來巨(ju)大挑(tiao)戰。為(wei)精心(xin)打造哈(ha)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)集團在南美(mei)市場(chang)的(de)首個水(shui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)總(zong)承(cheng)包項(xiang)(xiang)(xiang)目(mu),樹(shu)立水(shui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)領域的(de)標桿工(gong)程，哈(ha)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)集團國際公司克服諸多(duo)困難，在土建施工(gong)方面采取了多(duo)項(xiang)(xiang)(xiang)關鍵技術(shu)。

美(mei)納斯項目采用全(quan)斷(duan)面反(fan)井鉆(zhan)機(ji)設(she)備(bei)對通風電纜豎井和壓力(li)豎井進行開挖，創(chuang)下中資企業(ye)海(hai)外首例。2015年10月29日,直徑(jing)為(wei)5.5米，深(shen)度為(wei)452米的(de)壓力(li)豎井全(quan)斷(duan)面反(fan)擴工作(zuo)順利完成。壓力(li)豎井的(de)最(zui)終偏斜精準度、全(quan)斷(duan)面反(fan)擴直徑(jing)、深(shen)度在(zai)世(shi)界水(shui)電施工領域均處于領先水(shui)平，為(wei)哈電集(ji)團(tuan)水(shui)電項目建設(she)積累了(le)寶(bao)貴(gui)的(de)創(chuang)新性工程(cheng)經(jing)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)目高巖石硬度情況下，項(xiang)目部采用TBM(隧(sui)道掘(jue)進機)對14公里引(yin)水隧(sui)洞(dong)進行(xing)開挖(wa)。2017年3月21日,引(yin)水隧(sui)洞(dong)TBM段的全線(xian)精準貫通(tong), 開啟了哈電集團在TBM隧(sui)洞(dong)開挖(wa)管理(li)方(fang)面的新篇章，對未來開拓國(guo)際高端總承包市場(chang)增添(tian)了一把(ba)意(yi)義非(fei)凡的“金(jin)鑰匙”。

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(xiang)目臨時(shi)移交以(yi)來，美納斯項(xiang)目團隊(dui)積(ji)極克服各種不(bu)利(li)影響(xiang)因素，尤其在全球疫(yi)情(qing)蔓(man)延下(xia)，仍(reng)全力協(xie)調現場各方(fang)積(ji)極開展(zhan)土(tu)建(jian)消缺及機組(zu)檢修(xiu)工作，確(que)保了土(tu)建(jian)工程全部按(an)期(qi)履約，實力詮釋哈(ha)電集(ji)團疫(yi)情(qing)防控的落實落地和項(xiang)目管理的高(gao)質高(gao)效。
