近日，隨著最后一(yi)車石料傾入江中填(tian)平(ping)龍口，中國(guo)電(dian)建所(suo)屬(shu)水電(dian)四(si)局承建的(de)國(guo)家172工程——海南省北門江天角(jiao)潭水利樞紐(niu)工程成(cheng)功實現一(yi)期(qi)大(da)江截流。
天角潭(tan)水(shui)(shui)利樞(shu)紐工(gong)(gong)(gong)程位于海南省(sheng)儋(dan)州(zhou)市北門江干流中游河段(duan)，為國務(wu)院確定的172項節水(shui)(shui)供水(shui)(shui)重(zhong)大水(shui)(shui)利工(gong)(gong)(gong)程項目，以工(gong)(gong)(gong)業供水(shui)(shui)、農業灌溉為主(zhu)(zhu)，兼顧發電(dian)(dian)等綜合利用(yong)，是海南省(sheng)水(shui)(shui)網建設(she)規劃重(zhong)點項目之一(yi)。該(gai)工(gong)(gong)(gong)程樞(shu)紐建筑(zhu)物(wu)包(bao)括(kuo)主(zhu)(zhu)壩(ba)、4座副壩(ba)、灌區渠首工(gong)(gong)(gong)程、引水(shui)(shui)發電(dian)(dian)系(xi)統等。水(shui)(shui)電(dian)(dian)四局主(zhu)(zhu)要(yao)承擔主(zhu)(zhu)壩(ba)及(ji)副壩(ba)樞(shu)紐建筑(zhu)物(wu)、引水(shui)(shui)發電(dian)(dian)建筑(zhu)物(wu)及(ji)渠系(xi)建筑(zhu)物(wu)、交通工(gong)(gong)(gong)程、邊(bian)坡工(gong)(gong)(gong)程、管(guan)理區及(ji)魚類(lei)增殖站、水(shui)(shui)環保工(gong)(gong)(gong)程、機電(dian)(dian)及(ji)金(jin)屬結構、臨時工(gong)(gong)(gong)程等。
該(gai)工(gong)(gong)程(cheng)主(zhu)壩(ba)計(ji)劃一枯(ku)、二(er)(er)枯(ku)分(fen)期導(dao)(dao)(dao)(dao)截流(liu)施(shi)(shi)工(gong)(gong)。此次北門江一枯(ku)導(dao)(dao)(dao)(dao)截流(liu)，分(fen)水(shui)(shui)建筑(zhu)物為布置(zhi)在(zai)右岸10號壩(ba)段的(de)導(dao)(dao)(dao)(dao)流(liu)明渠(qu)。明渠(qu)斷面為倒(dao)梯形(xing)，渠(qu)底(di)寬度5米(mi)(mi)(mi)，渠(qu)高(gao)(gao)6米(mi)(mi)(mi)，進口(kou)(kou)底(di)板高(gao)(gao)程(cheng)22.00米(mi)(mi)(mi)，出口(kou)(kou)底(di)板高(gao)(gao)程(cheng)21.70米(mi)(mi)(mi),上游(you)圍(wei)堰布置(zhi)在(zai)壩(ba)上0-101.29米(mi)(mi)(mi)處(chu)，下游(you)圍(wei)堰布置(zhi)在(zai)壩(ba)下0+104.29米(mi)(mi)(mi)處(chu)，導(dao)(dao)(dao)(dao)流(liu)明渠(qu)布置(zhi)在(zai)主(zhu)壩(ba)0+221.5米(mi)(mi)(mi)處(chu)。施(shi)(shi)工(gong)(gong)期間，為確保天角潭水(shui)(shui)利(li)樞紐(niu)工(gong)(gong)程(cheng)2022年度主(zhu)壩(ba)澆筑(zhu)至48米(mi)(mi)(mi)高(gao)(gao)程(cheng)，項目部(bu)結合(he)施(shi)(shi)工(gong)(gong)現場(chang)實(shi)際情(qing)況，將二(er)(er)枯(ku)部(bu)分(fen)施(shi)(shi)工(gong)(gong)內容提前至一枯(ku)進行，以(yi)緩解二(er)(er)枯(ku)施(shi)(shi)工(gong)(gong)壓力(li)，確保在(zai)建工(gong)(gong)程(cheng)安全(quan)度汛(xun)。
據悉，天角(jiao)潭水(shui)利樞紐(niu)工程建成(cheng)后(hou)，可(ke)有(you)效(xiao)解決儋州(zhou)(zhou)市中和、東成(cheng)、新(xin)州(zhou)(zhou)、木棠、光村、峨(e)蔓6個鄉鎮(zhen)11.4萬畝農(nong)田灌溉問題，對發(fa)展地方熱帶(dai)特(te)色高(gao)效(xiao)農(nong)業(ye)、促進區域經濟社會可(ke)持續(xu)發(fa)展等具有(you)重要作用。
