近日，隨著(zhu)最后一車石料(liao)傾入江(jiang)中(zhong)(zhong)填平(ping)龍口，中(zhong)(zhong)國電建(jian)所屬水(shui)電四(si)局承建(jian)的(de)國家172工程(cheng)——海南省(sheng)北門江(jiang)天角(jiao)潭水(shui)利(li)樞(shu)紐工程(cheng)成功實現一期大江(jiang)截流。
天角潭水(shui)(shui)(shui)利(li)樞(shu)紐工(gong)(gong)程(cheng)(cheng)位于海(hai)南(nan)(nan)省儋州市北門江(jiang)干流中游河段(duan)，為國(guo)務院確(que)定(ding)的(de)172項(xiang)節水(shui)(shui)(shui)供(gong)水(shui)(shui)(shui)重(zhong)大水(shui)(shui)(shui)利(li)工(gong)(gong)程(cheng)(cheng)項(xiang)目，以工(gong)(gong)業供(gong)水(shui)(shui)(shui)、農業灌溉為主，兼顧(gu)發電(dian)等綜合(he)利(li)用，是海(hai)南(nan)(nan)省水(shui)(shui)(shui)網建(jian)設(she)規劃重(zhong)點項(xiang)目之(zhi)一。該工(gong)(gong)程(cheng)(cheng)樞(shu)紐建(jian)筑(zhu)(zhu)物(wu)包括主壩、4座副(fu)壩、灌區渠(qu)首(shou)工(gong)(gong)程(cheng)(cheng)、引(yin)水(shui)(shui)(shui)發電(dian)系(xi)統等。水(shui)(shui)(shui)電(dian)四局主要承(cheng)擔主壩及副(fu)壩樞(shu)紐建(jian)筑(zhu)(zhu)物(wu)、引(yin)水(shui)(shui)(shui)發電(dian)建(jian)筑(zhu)(zhu)物(wu)及渠(qu)系(xi)建(jian)筑(zhu)(zhu)物(wu)、交通工(gong)(gong)程(cheng)(cheng)、邊(bian)坡(po)工(gong)(gong)程(cheng)(cheng)、管理區及魚類增殖站(zhan)、水(shui)(shui)(shui)環保工(gong)(gong)程(cheng)(cheng)、機電(dian)及金屬結構、臨時工(gong)(gong)程(cheng)(cheng)等。
該工(gong)程(cheng)(cheng)主(zhu)壩計劃一枯(ku)(ku)(ku)、二(er)枯(ku)(ku)(ku)分期導截流(liu)施(shi)工(gong)。此次北門江(jiang)一枯(ku)(ku)(ku)導截流(liu)，分水建筑物為布置在(zai)右岸10號壩段的導流(liu)明渠(qu)(qu)。明渠(qu)(qu)斷面為倒梯形，渠(qu)(qu)底寬度(du)(du)5米(mi)(mi)(mi)，渠(qu)(qu)高(gao)6米(mi)(mi)(mi)，進口底板(ban)高(gao)程(cheng)(cheng)22.00米(mi)(mi)(mi)，出(chu)口底板(ban)高(gao)程(cheng)(cheng)21.70米(mi)(mi)(mi),上(shang)游(you)圍堰布置在(zai)壩上(shang)0-101.29米(mi)(mi)(mi)處(chu)(chu)，下(xia)游(you)圍堰布置在(zai)壩下(xia)0+104.29米(mi)(mi)(mi)處(chu)(chu)，導流(liu)明渠(qu)(qu)布置在(zai)主(zhu)壩0+221.5米(mi)(mi)(mi)處(chu)(chu)。施(shi)工(gong)期間，為確(que)保天角潭水利樞紐工(gong)程(cheng)(cheng)2022年度(du)(du)主(zhu)壩澆筑至48米(mi)(mi)(mi)高(gao)程(cheng)(cheng)，項目(mu)部(bu)結合施(shi)工(gong)現(xian)場實(shi)際(ji)情況，將(jiang)二(er)枯(ku)(ku)(ku)部(bu)分施(shi)工(gong)內(nei)容提前至一枯(ku)(ku)(ku)進行，以緩解二(er)枯(ku)(ku)(ku)施(shi)工(gong)壓力(li)，確(que)保在(zai)建工(gong)程(cheng)(cheng)安(an)全度(du)(du)汛。
據悉，天角潭水利樞紐工(gong)程(cheng)建(jian)成后，可有效解決儋州(zhou)市(shi)中和、東成、新(xin)州(zhou)、木(mu)棠、光村、峨蔓6個(ge)鄉鎮(zhen)11.4萬畝(mu)農田灌溉問(wen)題(ti)，對發(fa)展地方(fang)熱帶特色高效農業、促進(jin)區域經濟社會可持續發(fa)展等具有重要(yao)作用。
