近(jin)日(ri)，隨(sui)著最后一車石料(liao)傾入(ru)江(jiang)中填平龍口，中國(guo)電建所屬水(shui)電四局承建的國(guo)家172工程——海南省北門江(jiang)天角潭(tan)水(shui)利樞紐工程成(cheng)功實現一期大江(jiang)截流(liu)。
天角(jiao)潭(tan)水(shui)(shui)(shui)(shui)利(li)樞(shu)紐工(gong)(gong)(gong)程(cheng)(cheng)位于海(hai)南省(sheng)儋州(zhou)市北門江干流中游河段，為國務院(yuan)確定的172項節(jie)水(shui)(shui)(shui)(shui)供水(shui)(shui)(shui)(shui)重大水(shui)(shui)(shui)(shui)利(li)工(gong)(gong)(gong)程(cheng)(cheng)項目(mu)，以(yi)工(gong)(gong)(gong)業供水(shui)(shui)(shui)(shui)、農(nong)業灌溉(gai)為主，兼顧發(fa)電(dian)(dian)等綜合利(li)用，是海(hai)南省(sheng)水(shui)(shui)(shui)(shui)網建(jian)(jian)設規劃重點項目(mu)之(zhi)一。該工(gong)(gong)(gong)程(cheng)(cheng)樞(shu)紐建(jian)(jian)筑(zhu)物(wu)包括(kuo)主壩、4座副(fu)壩、灌區渠首工(gong)(gong)(gong)程(cheng)(cheng)、引(yin)水(shui)(shui)(shui)(shui)發(fa)電(dian)(dian)系統等。水(shui)(shui)(shui)(shui)電(dian)(dian)四局(ju)主要承擔主壩及(ji)副(fu)壩樞(shu)紐建(jian)(jian)筑(zhu)物(wu)、引(yin)水(shui)(shui)(shui)(shui)發(fa)電(dian)(dian)建(jian)(jian)筑(zhu)物(wu)及(ji)渠系建(jian)(jian)筑(zhu)物(wu)、交通工(gong)(gong)(gong)程(cheng)(cheng)、邊坡工(gong)(gong)(gong)程(cheng)(cheng)、管理區及(ji)魚類增殖(zhi)站、水(shui)(shui)(shui)(shui)環保工(gong)(gong)(gong)程(cheng)(cheng)、機電(dian)(dian)及(ji)金(jin)屬結構、臨時(shi)工(gong)(gong)(gong)程(cheng)(cheng)等。
該工(gong)程(cheng)(cheng)主(zhu)壩(ba)計(ji)劃一(yi)(yi)枯、二(er)枯分(fen)期(qi)(qi)導截流施(shi)工(gong)。此次北門江一(yi)(yi)枯導截流，分(fen)水(shui)建筑物為布置在右岸10號壩(ba)段的導流明(ming)渠(qu)(qu)。明(ming)渠(qu)(qu)斷面為倒梯(ti)形，渠(qu)(qu)底寬度(du)5米(mi)，渠(qu)(qu)高(gao)(gao)6米(mi)，進口(kou)底板高(gao)(gao)程(cheng)(cheng)22.00米(mi)，出口(kou)底板高(gao)(gao)程(cheng)(cheng)21.70米(mi),上游(you)圍(wei)堰布置在壩(ba)上0-101.29米(mi)處，下游(you)圍(wei)堰布置在壩(ba)下0+104.29米(mi)處，導流明(ming)渠(qu)(qu)布置在主(zhu)壩(ba)0+221.5米(mi)處。施(shi)工(gong)期(qi)(qi)間，為確(que)保天(tian)角潭(tan)水(shui)利(li)樞(shu)紐(niu)工(gong)程(cheng)(cheng)2022年度(du)主(zhu)壩(ba)澆筑至48米(mi)高(gao)(gao)程(cheng)(cheng)，項目部結合施(shi)工(gong)現場實(shi)際情況，將二(er)枯部分(fen)施(shi)工(gong)內容(rong)提前至一(yi)(yi)枯進行，以緩解(jie)二(er)枯施(shi)工(gong)壓力，確(que)保在建工(gong)程(cheng)(cheng)安全度(du)汛。
據悉，天角潭水利樞紐工程建成后(hou)，可(ke)有(you)效(xiao)解決儋(dan)州(zhou)(zhou)市中和、東成、新州(zhou)(zhou)、木棠、光村、峨蔓6個(ge)鄉鎮11.4萬畝農(nong)田(tian)灌溉問題，對發展地方熱(re)帶特(te)色高效(xiao)農(nong)業、促進(jin)區域(yu)經濟社會可(ke)持續發展等具(ju)有(you)重要作用。
