水庫意義
大(da)隆(long)(long)洞水(shui)庫(ku)位于(yu)(yu)臺山市端(duan)芬鎮(zhen)西部(bu)大(da)隆(long)(long)洞河上(shang)游(you),面(mian)(mian)積2.2萬畝,始建于(yu)(yu)1958年9月,僅(jin)用(yong)(yong)了十(shi)三個月時間便基本建成(cheng)主體(ti)工程,是一座以灌溉為主,兼防洪、發電(dian)、養魚綜合利用(yong)(yong)的(de)大(da)型水(shui)庫(ku)。集(ji)雨面(mian)(mian)積有(you)148平方公里,可(ke)容納(na)水(shui)量2.5億立方米。灌溉面(mian)(mian)積15萬畝,防洪保(bao)護(hu)面(mian)(mian)積25萬畝。大(da)隆(long)(long)洞水(shui)庫(ku)位于(yu)(yu)群山環(huan)抱之(zhi)中,空氣清(qing)新,環(huan)境幽靜(jing),湖(hu)光山色秀美,138個綠樹(shu)婆娑的(de)小島錯落湖(hu)中,因此有(you)“千島湖(hu)”之(zhi)稱,游(you)客可(ke)乘船暢游(you)“千島湖(hu)”。
建設過程
大隆洞水(shui)庫主副(fu)壩(ba)于(yu)1958年9月(yue)動工(gong)(gong)(gong)興建,1959年10月(yue)竣工(gong)(gong)(gong)。灌區渠道及(ji)附屬建筑物于(yu)1959年冬開(kai)工(gong)(gong)(gong),1960年春耕(geng)前完成。溢洪道于(yu)1964年動工(gong)(gong)(gong),1967年竣工(gong)(gong)(gong)。
庫區特征
主壩(ba)為均質土(tu)壩(ba),最(zui)大(da)(da)壩(ba)高(gao)39.2米(mi)(mi),壩(ba)頂長444米(mi)(mi)。副壩(ba)一座,位于右岸山坳(ao),最(zui)大(da)(da)壩(ba)高(gao)25.7米(mi)(mi),長175.6米(mi)(mi)。開敞式溢洪道設(she)于主壩(ba)左側,凈寬(kuan)24米(mi)(mi),分3孔設(she)8×4.5米(mi)(mi)鋼弧(hu)形閘門3扇(shan)。設(she)計(ji)最(zui)大(da)(da)泄洪流(liu)量903立(li)方米(mi)(mi)每秒(miao)。輸(shu)水管設(she)于副壩(ba),直徑(jing)1.9米(mi)(mi),鋼筋(jin)凝(ning)土(tu)結構,內鑲鋼管,設(she)計(ji)最(zui)大(da)(da)流(liu)量34.4立(li)方米(mi)(mi)每秒(miao)。
主壩采用(yong)水(shui)中(zhong)填土法(fa)施(shi)工(gong)(gong)(gong)(gong)(gong)(gong),是(shi)廣東省(sheng)大型水(shui)庫中(zhong)最早采用(yong)這一施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)方法(fa)的工(gong)(gong)(gong)(gong)(gong)(gong)程。施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)期(qi)間省(sheng)水(shui)電廳水(shui)利科學研究所土工(gong)(gong)(gong)(gong)(gong)(gong)室派工(gong)(gong)(gong)(gong)(gong)(gong)程師(shi)駐工(gong)(gong)(gong)(gong)(gong)(gong)地(di)抽(chou)樣檢查試驗,掌握(wo)工(gong)(gong)(gong)(gong)(gong)(gong)程質量,并(bing)于1959年(nian),在水(shui)庫工(gong)(gong)(gong)(gong)(gong)(gong)地(di)召開全省(sheng)水(shui)中(zhong)填土筑壩現場(chang)會(hui)議,推(tui)廣這一施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)新技術。
水庫主壩于1959年建(jian)成。壩高(gao)原為37.20米(mi)(mi),1975年河(he)南省大(da)水后,進(jin)行復核加固,將主壩加高(gao)2米(mi)(mi),培厚(hou)5米(mi)(mi),副壩亦相應加高(gao)培厚(hou),全線(xian)建(jian)防(fang)浪墻高(gao)1米(mi)(mi)。加固工程于1977年4月完成。
加固后(hou)的大隆(long)洞水庫(ku)淹(yan)沒耕地5700畝,遷移人口(kou)1900人,設計灌(guan)溉(gai)面積(ji)15萬(wan)(wan)畝,有(you)效灌(guan)溉(gai)面積(ji)13.5萬(wan)(wan)畝。壩后(hou)電站發(fa)電裝機3600千瓦。總工(gong)程費745萬(wan)(wan)元(yuan),其中(zhong)國家(jia)投(tou)資496.32萬(wan)(wan)元(yuan)。
