12月30日，由中(zhong)國能建葛洲壩(ba)集團(tuan)投資建設的(de)海口(kou)市南(nan)渡(du)江引水(shui)(shui)工(gong)(gong)程(cheng)中(zhong)西部供水(shui)(shui)線路(lu)正式通水(shui)(shui)，為工(gong)(gong)程(cheng)全面竣(jun)工(gong)(gong)奠定(ding)了堅實基礎。
該工(gong)(gong)(gong)程(cheng)是國家(jia)172項重大水利工(gong)(gong)(gong)程(cheng)項目之一，將與邁灣水利樞紐實現(xian)聯合(he)(he)調度，滿足海口市和江東新區高標準供水需求。該工(gong)(gong)(gong)程(cheng)總投資36.2億元，工(gong)(gong)(gong)程(cheng)供水線(xian)路總長50.34公里(li)，由輸(shu)(shu)配水工(gong)(gong)(gong)程(cheng)、灌(guan)區工(gong)(gong)(gong)程(cheng)、五(wu)源河綜合(he)(he)治理工(gong)(gong)(gong)程(cheng)及永(yong)莊水庫到沙坡水庫連通(tong)工(gong)(gong)(gong)程(cheng)等(deng)組成，主(zhu)要建設內容包括輸(shu)(shu)水隧道、輸(shu)(shu)水箱涵、渡槽、輸(shu)(shu)水管道等(deng)。
工(gong)程中西供(gong)水(shui)(shui)(shui)線(xian)起(qi)點(dian)為東山泵(beng)站(zhan)，終點(dian)為永莊水(shui)(shui)(shui)庫(ku)和玉鳳水(shui)(shui)(shui)庫(ku)；東部(bu)供(gong)水(shui)(shui)(shui)線(xian)路(lu)起(qi)點(dian)龍塘右泵(beng)站(zhan)，終點(dian)為江東水(shui)(shui)(shui)廠，年供(gong)水(shui)(shui)(shui)量(liang)41630萬立方米，澆灌面積(ji)達26.86萬畝，將(jiang)切實解決(jue)230萬人口飲水(shui)(shui)(shui)問題(ti)。
南渡(du)江(jiang)引水(shui)(shui)工程于2015年11月(yue)18日(ri)開(kai)工建設(she)，歷(li)時五載(zai)，共計1867天。工程建設(she)其(qi)間，經歷(li)汛期(qi)臺風暴(bao)雨、復雜地質(zhi)條件、圖(tu)紙(zhi)供應不(bu)及時等各方(fang)面影響，特別(bie)是工程關鍵線路——12.96公(gong)里長隧洞(dong)工程火山巖(yan)石空洞(dong)、裂隙發育、透水(shui)(shui)性(xing)強，區域構造穩(wen)定性(xing)差，火山巖(yan)洞(dong)內(nei)突泥、涌水(shui)(shui)、塌方(fang)、地陷等地質(zhi)問(wen)題給工程施工帶來巨大難度。
中(zhong)西(xi)部供水(shui)線(xian)路通(tong)水(shui)是南渡(du)江工(gong)程實(shi)現的重大節(jie)點。在后續(xu)工(gong)作中(zhong)，葛洲壩集團將科學(xue)組織、精心安(an)排，繼續(xu)攻克灌區水(shui)塔池、管道(dao)、田間工(gong)程等難題，為南渡(du)江引水(shui)工(gong)程全(quan)面(mian)竣工(gong)打下堅實(shi)基(ji)礎，助力海(hai)南自由(you)貿(mao)易港建設。
