[摘要]异重流排沙一般仅在调水调沙后期采用,只能将运行至坝前的部分细粒径泥 沙排出;射流清淤技术在浅水中进行局部的采砂、清淤有广泛的应用,二者在深水泥沙处理 上均存在一定的局限性。为此,结合异重流产生和运动的特点,提出利用自激吸气式脉冲射 流装置制造人工异重流进行冲驱泥沙的新方法。研究并探讨了技术的可行性及影响因素,以 及清淤河段的选择,对脉冲射流的冲沙速度等技术参数进行了论证,以求解决深水条件下大 面积、长距离的大量排沙清淤的技术难题。

Abstract: Density disilting generally only used in the water and sediment regulation later, Can only be run to dam the part before the fine grain size of sediment; Jet dredging technology in shallow water for local sand, silt is widely used, two in certain limitations of deepwater sediment treatment are. Therefore, combined with the characteristics of density current generation and movement, the pulse jet device for producing artificial density current new method of scouring sediment by self suction. Research and discuss the feasibility and influence factors of technology, as well as the choice of the dredging of river, The pulse jet flushing speed technology parameters are discussed, in order to solve the Deepwater conditions of large area, long distance, large desilting at technical problem.
Key words: self aspirated; pulsed jet; artificial density curren
