1月30日，公司承建的國家(jia)重大水利工(gong)(gong)程、國家(jia)水網(wang)骨干工(gong)(gong)程——珠(zhu)江三角洲(zhou)水資源(yuan)配置工(gong)(gong)程全線(xian)正(zheng)式通水進(jin)入初期(qi)運行階段。

該工(gong)程(cheng)(cheng)(cheng)全長約(yue)113.2公(gong)里，西起西江干流佛山順德鯉魚洲，東(dong)至深(shen)圳公(gong)明水(shui)(shui)庫，由(you)一(yi)條(tiao)干線(xian)(xian)、兩(liang)條(tiao)分干線(xian)(xian)、一(yi)條(tiao)支(zhi)線(xian)(xian)、三座(zuo)泵站和四座(zuo)調蓄(xu)水(shui)(shui)庫組成，全線(xian)(xian)采用地下深(shen)埋盾構方式(shi)，在(zai)縱深(shen)40-60米(mi)的(de)(de)地下建造，最大(da)限(xian)度(du)保護灣(wan)區生態(tai)環境，為未來發展(zhan)預留寶貴(gui)地表和淺層地下空間，設計年(nian)供水(shui)(shui)量17.08億立方米(mi)，是(shi)保障粵港澳大(da)灣(wan)區供水(shui)(shui)安(an)(an)全、生態(tai)安(an)(an)全的(de)(de)重大(da)基礎設施，也是(shi)名副其實的(de)(de)“超(chao)級工(gong)程(cheng)(cheng)(cheng)”，建設任務(wu)艱巨(ju)。該工(gong)程(cheng)(cheng)(cheng)由(you)中(zhong)國(guo)電(dian)(dian)(dian)建所屬水(shui)(shui)電(dian)(dian)(dian)四局(ju)(ju)、水(shui)(shui)電(dian)(dian)(dian)七局(ju)(ju)、水(shui)(shui)電(dian)(dian)(dian)八(ba)局(ju)(ju)、水(shui)(shui)電(dian)(dian)(dian)十一(yi)局(ju)(ju)、電(dian)(dian)(dian)建市政(zheng)公(gong)司、水(shui)(shui)電(dian)(dian)(dian)十四局(ju)(ju)等單位參與(yu)(yu)建設，中(zhong)南院參與(yu)(yu)工(gong)程(cheng)(cheng)(cheng)監理。

工程(cheng)建(jian)設(she)(she)過程(cheng)中需要三(san)次穿越西江，而珠三(san)角地(di)區河(he)網(wang)密(mi)布、建(jian)筑(zhu)密(mi)集(ji)、路(lu)網(wang)交(jiao)錯，地(di)下(xia)斷層(ceng)紛(fen)繁、地(di)質多變，盾(dun)(dun)構(gou)(gou)挖掘(jue)更需要應對大(da)埋深、極破碎富水(shui)地(di)層(ceng)、大(da)坡度、小轉彎(wan)等多種(zhong)難題(ti)。建(jian)設(she)(she)者們積極開展科研攻(gong)關、原型(xing)試驗(yan)，攜手攻(gong)克長距(ju)離深埋盾(dun)(dun)構(gou)(gou)施(shi)工、高(gao)水(shui)壓襯(chen)砌設(she)(she)計施(shi)工、寬揚程(cheng)變速水(shui)泵(beng)研發(fa)、長距(ju)離深埋管道(dao)檢修等多項(xiang)世界(jie)級難題(ti)，自主研發(fa)了超(chao)大(da)型(xing)輸水(shui)隧(sui)洞大(da)直(zhi)徑鋼管運輸臺車和(he)國內首(shou)臺大(da)型(xing)鋼管FBE熱熔結環氧粉末防腐中頻加熱設(she)(she)備(bei)，并取(qu)得“提前(qian)完成(cheng)地(di)連(lian)墻施(shi)工、多次刷新單機掘(jue)進(jin)紀錄、超(chao)額完成(cheng)年(nian)度目標任務、首(shou)個實(shi)現(xian)六(liu)條盾(dun)(dun)構(gou)(gou)隧(sui)洞貫(guan)通的(de)標段(duan)、首(shou)個具備(bei)通水(shui)條件的(de)標段(duan)”等多項(xiang)矚目成(cheng)績。

工(gong)程通(tong)水(shui)后，標志著廣(guang)(guang)東實現了“西水(shui)東濟”，徹(che)底改變(bian)廣(guang)(guang)州市南沙區(qu)、深圳市及東莞市單一(yi)供(gong)(gong)水(shui)格局，并為香港、廣(guang)(guang)州番禺、佛山順德(de)等地提供(gong)(gong)應急備用水(shui)源，超3200萬人受益，支(zhi)撐約1.7萬億(yi)元GDP用水(shui)需求，還可(ke)逐(zhu)步退還東江流(liu)域生態用水(shui)，進(jin)一(yi)步保(bao)障(zhang)粵港澳(ao)大灣區(qu)供(gong)(gong)水(shui)安(an)全(quan)、生態安(an)全(quan)。
