摘　　要：为提高水库的综合效益,延长水库的使用寿命,研究了水力自耕吸泥清淤装置,该装置配置水力自耕吸头和输沙管道,利用水库上下游水位差,结合灌溉用水流量,可全天候、高效率地将库底淤泥输送到大坝下游灌区,具有低耗能、低耗水、全自动的特点。榆林河水库的应用结果表明:该装置清淤的直接费用只有机械清淤费用的10%,还可以淤地造田,改良土壤,没有任何污染。In order to improve the comprehensive benefit of reservoir and prolong the service life of the reservoir,hydraulic self-ploughing dred-ging device had been studied. The device was composed of hydraulic self farming suction head and the sediment transport pipeline. Using of reser-voir water level difference and combining with irrigation water flow,the device could transport silt to the downstream irrigation area in all-weather conditions and high efficiency. It had the characteristics of low energy consumption,low water consumption and full automation. The results of ap-plication of Yulinhe Reservoir show that the direct cost of this dredging only costs 10% of the mechanical dredging and the method can also reclaim farmland and improve the soil without any pollution.
