金沟河引水工程渗管反滤料渗透特性试验研究

Experimental Study on Permeability Characteristics of Filter Material in Seepage Pipe of Jingou River Diversion Project

以金沟河引水工程为例,进行了其引水工程渗管反滤料渗透特性试验研究,主要包括试验装置的设计,试验材料的选择,试验方案设计,试验内容及过程的分析,并分清水试验和浑水试验两种工况对渗管反滤料渗透试验过程及结果进行分析探讨。研究结果表明,清水试验渗管反滤料渗水过滤效果较好,而浑水试验中随各反滤层泥膜厚度的增大,渗透系数减小,渗管出水效果不明显,文章的研究结果可为同类型引水工程渗管取水设计提供借鉴参考。

Taking the Jingou River diversion project as an example,this paper conducts an experimental study on the permeability characteristics of the filter material in the seepage pipe of the diversion project,it mainly includes the design of the test device,the selection of the test material,the design of the test scheme,the analysis of the test contents and the process.In addition,the process and results of infiltration test of filter material in seepage pipe are analyzed and discussed by separating clear water test and muddy water test.The results show that the filtration effect of the filter material is better in the clear water test,while in the muddy water test,with the increase of the mud film thickness of each filter layer,with the decrease of permeability coefficient,the effluent effect of seepage tube is not obvious.The research results of this paper can provide reference for the design of seepage pipe intake in the same type of water diversion projects.
