12月30日，由中國(guo)能建葛洲(zhou)壩集團(tuan)投資建設的海口市(shi)南渡江(jiang)引水(shui)工(gong)程中西(xi)部供(gong)水(shui)線(xian)路正(zheng)式通(tong)水(shui)，為(wei)工(gong)程全面(mian)竣工(gong)奠定了堅實基礎(chu)。
該(gai)工(gong)(gong)程(cheng)(cheng)(cheng)是國家172項重大(da)水(shui)利工(gong)(gong)程(cheng)(cheng)(cheng)項目(mu)之一，將與邁灣水(shui)利樞紐實現聯合(he)調度(du)，滿足海口市和江東新(xin)區(qu)高標準供(gong)水(shui)需求。該(gai)工(gong)(gong)程(cheng)(cheng)(cheng)總投(tou)資36.2億元，工(gong)(gong)程(cheng)(cheng)(cheng)供(gong)水(shui)線路總長50.34公里(li)，由輸(shu)(shu)配水(shui)工(gong)(gong)程(cheng)(cheng)(cheng)、灌區(qu)工(gong)(gong)程(cheng)(cheng)(cheng)、五源河綜合(he)治理(li)工(gong)(gong)程(cheng)(cheng)(cheng)及永(yong)莊水(shui)庫(ku)到沙坡水(shui)庫(ku)連通工(gong)(gong)程(cheng)(cheng)(cheng)等組成，主(zhu)要建(jian)設內容包括輸(shu)(shu)水(shui)隧道、輸(shu)(shu)水(shui)箱涵、渡槽、輸(shu)(shu)水(shui)管(guan)道等。
工(gong)程中西(xi)供(gong)水(shui)(shui)線起點(dian)(dian)為東(dong)山泵站(zhan)，終(zhong)點(dian)(dian)為永莊水(shui)(shui)庫(ku)和玉(yu)鳳水(shui)(shui)庫(ku)；東(dong)部供(gong)水(shui)(shui)線路起點(dian)(dian)龍(long)塘右(you)泵站(zhan)，終(zhong)點(dian)(dian)為江東(dong)水(shui)(shui)廠，年供(gong)水(shui)(shui)量41630萬(wan)(wan)立(li)方米，澆灌面積達26.86萬(wan)(wan)畝，將切實解(jie)決230萬(wan)(wan)人口(kou)飲水(shui)(shui)問題。
南渡江引(yin)水(shui)工(gong)程(cheng)(cheng)于(yu)2015年(nian)11月18日(ri)開工(gong)建(jian)設(she)，歷時五載，共計1867天。工(gong)程(cheng)(cheng)建(jian)設(she)其間，經(jing)歷汛期(qi)臺風(feng)暴(bao)雨(yu)、復雜地質條(tiao)件、圖紙(zhi)供(gong)應(ying)不及時等各方(fang)面(mian)影響，特別是工(gong)程(cheng)(cheng)關鍵線(xian)路——12.96公里長隧洞(dong)工(gong)程(cheng)(cheng)火山巖(yan)石空洞(dong)、裂隙發育、透水(shui)性強，區域(yu)構造穩定性差，火山巖(yan)洞(dong)內突泥(ni)、涌水(shui)、塌方(fang)、地陷等地質問(wen)題給工(gong)程(cheng)(cheng)施(shi)工(gong)帶來巨(ju)大難度。
中西部(bu)供(gong)水線路通水是(shi)南渡江工(gong)程(cheng)實現的重大(da)節(jie)點。在后(hou)續工(gong)作中，葛洲(zhou)壩集(ji)團將科(ke)學組(zu)織、精心(xin)安排，繼續攻克(ke)灌區水塔(ta)池(chi)、管(guan)道、田間工(gong)程(cheng)等(deng)難(nan)題，為南渡江引水工(gong)程(cheng)全面竣(jun)工(gong)打下堅實基礎，助(zhu)力海南自由貿(mao)易港(gang)建設。
