北京市某地下水厂设计规模为37万吨/日,由北京市市政设计院设计,北京市市政三公司施工。该水厂水源地位于某河冲积洪积扇中部东侧河漫滩上的狭长地带。水源井设在该冲积洪积扇的地下水溢出带附近,地下水位一般为0.5～1.5米左右。水源地的输水联络管全长约18公里,其口径分别为Dg800、Dg1000、Dg1200、Dg1400四种,其中Dg1000及Dg1200为预应力钢筋混凝土管道。输水联络管西距河道约150～300米左右。 The design scale of a certain groundwater plant in Beijing is 370,000 tons/day, which is designed by the Beijing Municipal Design Institute and constructed by the municipal municipal government. The water source of the plant is located in a narrow strip of land on the floodplain in the middle of the river in the middle of a river alluvial-proluvial fan. The water source well is located near the groundwater overflow zone of the alluvial alluvial fan, and the groundwater level is generally about 0.5 to 1.5 meters. The length of the water transfer liaison pipe in the water source is about 18 kilometers, and its calibers are Dg800, Dg1000, Dg1200, Dg1400, of which Dg1000 and Dg1200 are prestressed reinforced concrete pipes. The water transfer liaison pipe is about 150 to 300 meters away from the river.
