摘要
介绍了黄河第一座排沙漏斗工程的成功运行经验,并对其其原型观测结果进行了分析:对粒径大于0.1,0.05,0.025mm泥沙的平均截沙率分别达到96.58%,81.37%和78.71%,而平均排沙耗水量为7.23%。这一结果充分说明排沙漏斗的截沙率和排沙耗水量等重要指标都远优于过去黄河上普遍采用的条渠或者复合型厢形沉沙池等排沙设施。同时也说明排沙漏斗能有效地排除推移质泥沙,对悬移质泥沙的排除亦非常有效,尤其是为黄河泥沙的治理开辟了一条新途径。
This paper introduces successful operation experiences of the first sediment funnel engineering of the Yellow River in detail,especially its prototype ovservation results:The sediment whose grain diameter is larger than 0.1 mm,0.05 mm and 0.025 mm is intercepted efficiently by the sediment funnel, whose average sediment interceptions are respectively 96.58%,81.37% and 78.71%,however, average water cnsumption is only 7.23 percent of design discharge, which shows the important indexes of the sediment funnel,such as sand interception, water consumption and etc. are better than those of other desilting works. At the same time, this paper also proves that sediment funnel can effectively eliminate not only bed load but also suspended load, especially, sediment funnel is a new works with training for sediment of Yellow River.
