1 工程概况山西省万家寨引黄工程联接段汾河水库取水工程是中国水利水电第五工程局承建,于1998年8月18日开工,总工期28个月。该工程包括汾河水库内进水塔一座、竖井、坝下隧洞、交通桥和部分压力钢管道组成,进水塔长15.3m,宽18m,高41.2m;竖井深21.5m,内径3m;坝下隧洞长435m,内径3m,交通桥宽2.8m,长100m;内径3m 的钢管和钢叉管、闸门、拦污栅、启闭机等制作及安装。汾河水库位于山西省太原市娄烦县下石家庄附近,总库容7亿 m~3,其已建工程项目包括拦洪大坝、4m 输水洞、8m 泄洪洞、溢洪道和电站等主体工程,大坝为水中填土均质坝,最大坝高60m。中水五局承建的主体工程中的坝前进水塔座落在水库中,距副坝约100m 处。其地质条件为淤泥、壤土、砂砾石和基岩,由于汾河水库为运行中的水库,它负担着下游150万亩农田的灌溉、用水和太原市防洪的重要作用,在进水塔施工期间,施工必须绝对服从水库的春灌、防洪、冬灌的要求,这给施工带来极大的难
1 Project Overview Shanxi Wanjiazhai Yellow River Diversion Project Fenhe reservoir water intake project is the Fifth Engineering Bureau of China Water Conservancy and Hydropower Construction, started on August 18, 1998, the total duration of 28 months. The project includes a water tower in Fenhe Reservoir, a shaft, a tunnel under the dam, a traffic bridge and part of the pressure steel pipe. The intake tower is 15.3m long, 18m wide and 41.2m high. The shaft is 21.5m deep and has an inner diameter of 3m. The next tunnel is 435m long and has an inner diameter of 3m and a bridge width of 2.8m and a length of 100m. Steel pipes and forks with inner diameter of 3m, gates, trash rack and hoist are manufactured and installed. Fenhe Reservoir is located near Shijiazhuang, Loufan County, Taiyuan City, Shanxi Province with a total storage capacity of 700 million m 3. Its completed projects include main dam projects such as flood dam, 4m water diversion tunnel, 8m spillway tunnel, spillway and power station, Dams for water filling homogeneous dam, the maximum dam height 60m. In the construction of five water bureaus of the main project in front of the water tower is located in the dam, about 100m away from the secondary dam. Its geological conditions are silt, loam, sand, gravel and bedrock. Since Fenhe Reservoir is a reservoir in operation, it is responsible for the irrigation and water use of 1.5 million mu of farmland in the lower reaches and the important role of flood control in Taiyuan City. During the construction of the intake tower, Construction must absolutely obey the requirements of spring irrigation, flood control and winter irrigation in reservoirs, which brings great difficulties to construction
