厄瓜多爾當(dang)地(di)時間2016年4月16日發生7.8級(ji)強烈地(di)震。中國電(dian)建承(cheng)建的辛(xin)克雷水電(dian)站(zhan)以(yi)過硬(ying)的質(zhi)量，在此(ci)次強震中經受住了強震考(kao)驗，并(bing)在震后救災(zai)中發揮積極(ji)作(zuo)用。
辛克雷水(shui)(shui)電(dian)(dian)(dian)站(zhan)是利用(yong)中國技術、中國資金在拉美建成(cheng)投產的(de)最大規(gui)模水(shui)(shui)電(dian)(dian)(dian)站(zhan)，首批機(ji)組(zu)于2016年4月13日并網(wang)發電(dian)(dian)(dian)。地(di)震發生后，電(dian)(dian)(dian)站(zhan)自動啟動保護系統，機(ji)組(zu)主動關停。中方(fang)迅速(su)排查(cha)確(que)認電(dian)(dian)(dian)站(zhan)安然(ran)無恙后，于震后第二天起(qi)，確(que)保每天2臺(tai)機(ji)組(zu)按140兆瓦向(xiang)厄(e)瓜多爾電(dian)(dian)(dian)網(wang)供(gong)電(dian)(dian)(dian)，源源不(bu)斷地(di)輸送(song)著供(gong)救災和醫療使用(yong)的(de)寶貴電(dian)(dian)(dian)能，為抗災提供(gong)電(dian)(dian)(dian)力保障。
2010年7月28日，辛(xin)克雷水(shui)電(dian)站正式開工(gong)。電(dian)站由中國(guo)資(zi)金、技術、制造以設(she)計、采(cai)購、施(shi)工(gong)（EPC）模式總承(cheng)包(bao)建設(she)，中國(guo)電(dian)建旗(qi)下的(de)國(guo)際(ji)公司與水(shui)電(dian)十四局組成聯營體負責具體實施(shi)。
中(zhong)(zhong)國電建敢(gan)于(yu)實(shi)事求是(shi)，把經過魯布革(ge)、三峽、小浪(lang)底(di)、溪洛渡工(gong)(gong)(gong)程檢驗的(de)施工(gong)(gong)(gong)技術(shu)引薦到辛克雷項目中(zhong)(zhong)，用(yong)(yong)(yong)大(da)量(liang)無(wu)以雄(xiong)辯(bian)的(de)工(gong)(gong)(gong)程范例增添著“中(zhong)(zhong)國元素”，在(zai)(zai)南美樹立起一(yi)個又(you)一(yi)個“中(zhong)(zhong)國標準”——壓(ya)(ya)力(li)管道500米(mi)級1號豎(shu)井高(gao)強度(du)、高(gao)流態(tai)混凝(ning)土采(cai)(cai)用(yong)(yong)(yong)溜(liu)管垂直(zhi)輸(shu)送(song)試(shi)驗成(cheng)功，混凝(ning)土質量(liang)得到保證，獲得監理及業主認(ren)同。解決了500米(mi)級深井混凝(ning)土輸(shu)送(song)問題；高(gao)水(shui)頭(tou)月牙肋鋼(gang)岔管現場制造安(an)裝工(gong)(gong)(gong)藝(yi)，在(zai)(zai)提高(gao)生產效益的(de)同時確保了制作安(an)裝的(de)質量(liang)，形(xing)成(cheng)了一(yi)套既(ji)高(gao)效又(you)經濟的(de)工(gong)(gong)(gong)藝(yi)方法；采(cai)(cai)用(yong)(yong)(yong)陶瓷(ci)襯墊(dian)的(de)單(dan)面(mian)(mian)焊(han)雙(shuang)面(mian)(mian)成(cheng)型技術(shu)在(zai)(zai)厄瓜多爾(er)CCS水(shui)電站壓(ya)(ya)力(li)鋼(gang)管制造中(zhong)(zhong)的(de)運用(yong)(yong)(yong)，根據CCS水(shui)電站壓(ya)(ya)力(li)鋼(gang)管鋼(gang)板厚(hou)度(du)大(da)、直(zhi)管縱縫、環縫焊(han)接(jie)中(zhong)(zhong)采(cai)(cai)用(yong)(yong)(yong)埋弧自(zi)動焊(han)進行(xing)(xing)焊(han)接(jie)的(de)特點(dian)。將(jiang)焊(han)接(jie)坡口(kou)設計(ji)為X型坡口(kou)，把襯墊(dian)放在(zai)(zai)焊(han)接(jie)接(jie)頭(tou)坡口(kou)背面(mian)(mian)，從正面(mian)(mian)采(cai)(cai)用(yong)(yong)(yong)進行(xing)(xing)CO2氣體保護焊(han)打底(di)，從而實(shi)現單(dan)面(mian)(mian)焊(han)雙(shuang)面(mian)(mian)成(cheng)型工(gong)(gong)(gong)藝(yi)。
