1 概况 野沟门水电站系坝后式电站,最高水头23.7m,装机容量3×250kw。压力管道按斜向进水布置。主管道直径1.5m,机组分叉管直径0.8m,均为预制混凝土结构;在管道上方覆盖0.5m厚混凝土。该电站于1979年建成投产后不多久,在管道上方地面就产生渗水,至1992年情况逐渐严重,地面形成积水。特别是冬季,渗水冻成的冰层达15cm厚,给电站职工巡视设备带来不安全因素。经停水
1 Overview Yegoumen Hydropower Station dam-type power station, the highest head 23.7m, installed capacity of 3 × 250kw. Pressure pipe according to oblique water arrangement. The main pipe diameter of 1.5m, the unit divergent pipe diameter of 0.8m, are precast concrete structures; 0.5m thick concrete covered in the top of the pipeline. Shortly after the power station was put into operation in 1979, water leakage occurred on the ground above the pipeline. By 1992, the situation became grave and ground water formed. Especially in winter, ice seepage into the ice layer of 15cm thick, power plant workers patrol equipment insecurity. After stopping water
