摘 要:1988年5月至1989年7月,河南黄河河务局在封丘曹岗进行了吸泥船远距离放淤固堤试验。试验采用6160A型柴油机和10PNK—20型泥浆泵,以二级接力的方式进行,最大试验输沙距离为3010m。文章着重叙述了输沙阻力系数及其影响因素、流量与输距的关系、吸泥泵总扬程与输距的关系等方面的试验成果,比较了吸泥船远距离放淤固堤与人工筑堤、铲运机筑堤的经济效益。分析认为,进一步采取措施减小阻力系数,还可使输距在3010m的基础上再延长300—500m。The test, consolidating dykes by transporting sediment with a suction dredger for a long-distance, was made in Fengqiu section from May 1988 to July 1989 by Henan Provincial Yellow River Bureau, in which the maximum transporting dis tance reached 3010m. This paper mainly discusses the coefficient of resist ance in transporting sediment and affecting factors, relations between discharge and trans ported distance and between lift and distance, compares the economic benefit of consolidating dykes with this method and with other methods of manual work or ;a scraper. It points out in the last that the transporting distance can be increased to 300-500m based on present 3010m if the coefficient of resist ance is tried to reduce.
