贵县覃塘公社广大贫下中农,发扬敢想敢干和自力更生的精神,从1972年1月开始,用9个月时间,修建了一座挡水浆砌石重力拱坝。施工速度快,当年施工,当年发挥了效益。该坝控制集雨面积11公里~2,总库容260万米~3,可灌农田0.8万亩,水电站装机约140瓩。坝体尺寸:坝顶高程165米,最大坝高31米,拱外半径55米,定中心角110°,坝顶弧长104米,坝顶宽2米,底宽14.9米。迎水坡坡度为0,背水坡坡度为0.55。坝身用~#50～~#80浆砌石,距上游面1.5米处设~#100砼防渗墙,墙厚为0.5～1.5米。坝体总工程量为1.44万米~3,其中包括防渗墙砼0.28万米~3。总共用去水泥1969吨,木材30米~3。总工日32万。
Guantang commune in the vast majority of poor and middle peasants, to carry forward the spirit of dare to dare to do and self-reliance, from January 1972 onwards, with 9 months time, built a water blocking masonry gravity arch dam. Construction speed, then construction, then play a benefit. The dam control rain catchment area of 11 km ~ 2, with a total storage capacity of 2.6 million meters ~ 3, irrigation of farmland of 8,000 acres, hydropower station installed capacity of about 140 瓩. Dam body size: The dam crest elevation is 165 meters, the maximum dam height is 31 meters, the arch outer radius is 55 meters, the center angle is 110 °, the crest arc length is 104 meters, the crest width is 2 meters and the bottom width is 14.9 meters. Water slope slope 0, back slope gradient 0.55. Dam body ~ # 50 ~ ~ # 80 Masonry stone, located 1.5 meters upstream from the surface to set # 100 concrete cutoff wall, the wall thickness of 0.5 to 1.5 meters. The total volume of the dam is 14,400m ~ 3, including 28,000m ~ 3 of impermeable wall concrete. A total of 1969 tons of cement used to go, timber 30 meters ~ 3. The total working day 320,000.
