引黄济青工程是自黄河引水长距离明渠输水的跨流域调水工程。输水河全长253km,其中207km采用了塑膜防渗,聚苯乙烯保温板防冻胀,排水暗管防扬压力,混凝土板护面固床的渠道衬砌“三防”技术。该工程自1989年11月25日通水以来,己运行10年。10年来输水安全运行的关键之一是停止输水的调度。如果调度不当就会造成输水河衬砌滑坡、输水河渗透破坏,酿成事故,带来损失。
The project of Yellow Diversion Project is an inter-basin water transfer project that transports water from the Yellow River diversion long-distance open channel. Water river length of 253km, of which 207km plastic membrane impermeable, polystyrene insulation board frost heave, drainage tube anti-Yang pressure, concrete slab solid bed channel lining “three defenses” technology. The project has run for 10 years since it opened to water on November 25, 1989. One of the keys to the safe operation of water conveyance over the past 10 years is to stop the dispatch of water. If dispatched improperly, it will cause the lining of the water conveyance river to cause landslides and infiltration and destruction of the water conveyance river, causing accidents and bringing losses.
