陕西省彬县南玉子乡高渠村5组和录长村1组均处泾河北岸,主要耕种河川水地。1966年泾河洪水暴涨,两村的河川地遭受严重冲毁,特别是高渠村5组被冲毁660亩河川地,下余的120亩被两股泾河水绕成一个夹心滩,多年来靠木船摆渡来经营这块土地。 1979年10月,这两个村民小组的群众在县水保站的协助下,在新开河槽中部最窄处筑起1座拦泥淤地坝,以后又逐年在老河道沿岸布设园盘丁坝12座。施工中,根据新河道出水口与主河道交汇处有一突出石山嘴的特定条件,将引洪淤地简化为打坝淤地。主体工程淤地坝设计坝高10米,平均长度102米,顶宽10米,底宽50米,碾压回填土方3.4万立方米,选定坝轴线距上游进水口1000米,距下游出水口740米,坝上蓄洪拦泥,坝下利用右嘴阻挡引起洪水回旋进行落淤,1980年夏收前,主体工程基本竣工,当年汛期淤地650亩。至1984年,前后三次共淤地794亩,其中上坝470亩,下坝324亩,坝上坝下淤地距坝顶高差分别为0.2~0.5米,拦泥总量达到397万吨。
5 groups of Gaoqu Village and Nanchang Village of Binxian County, Shaanxi Province are all located at the north bank of Jinghe River and mainly cultivate river water. In 1966, the flood of Jinghe River skyrocketed, and the rivers and lakes of the two villages suffered serious damage. In particular, the 5 groups of Gaoqu Village were destroyed by 660 mu of river land. The remaining 120 mu of land was surrounded by two rivers of Jinghe River and became a sand beach. By wooden ferry to operate this piece of land. In October 1979, with the assistance of the County Soil and Water Conservation Administration, the masses of the two villager groups built a mud dam in the narrowest part of the central part of the Xinkaihe River, 12 seats. During the construction, according to the specific conditions of the Shishanzui at the junction of the new waterway outlet and the main riverway, the flood diversion silt will be simplified as dam silt. The main project silt dam design dam height of 10 meters, an average length of 102 meters, the top width of 10 meters, the bottom width of 50 meters, crushed backfill earth 34,000 cubic meters, the selected dam axis 1000 meters upstream from the inlet, 740 meters, the reservoir dam on the dam, dam blocking the right mouth caused by the flood swing siltation, 1980 before the close of the summer, the main project was basically completed, when the flood season 650 acres of silt. By 1984, 794 hectares of silt land had taken place before and after three times, of which 470 mu was on the dam and 324 hectares were on the dam. The elevation difference between the silt below the dam dam and the crest of the dam was 0.2-0.5 m respectively, and the total amount of silt arrest reached 3.97 million tonnes.
