摘要
出水量和出水浊度是渗管取水工程设计的2个重要参数.通过物理模型试验分析了不同河床砂厚度在不同流量下对渗管取水出水量及出水浊度的影响.试验结果表明:渗管取水从取水之初到取水稳定其出水量及浊度均存在逐渐递减最终趋于稳定的过程.河床砂厚度对渗管取水出水量以及出水浊度都有一定的影响,当来水流量不变时,随着河床砂厚度增加渗管出水量逐渐增加,出水浊度逐渐减小;当河床砂厚度不变时,随着来水流量增大渗管出水量逐渐增加,出水浊度逐渐减小.试验所得结论与理论计算结果以及实际工程运行情况相符合,可用于实际工程,为以后渗管取水工程设计提供参考.
When the hydrogeological conditions are suitable,the permeability tube for water project has the advantages of no pharmacy,low operating costs,good water quality,etc. It has been widely used in daily life,industrial and agricultural production. The water yield and the turbidity of treated water are two important design parameters of the permeability tube for water project. In the permeability tube for water project,the influence of the thickness of the original river sand on the water yield and the turbidity of treated water is analyzed based on the model experiment. The experimental result is consistent with the calculated results and the actual operation of the project. So the results can be used in the actual project,and provide a reference for future water infiltration pipe engineering. The results show that there is a gradually decreasing process from the beginning to the eventually stabilized phase in the permeability tube for water project. With the increase of the thickness of the original river sand,the water yield increase,the turbidity of treated water decrease; with the increase of the amount of water,the water yield increase,the turbidity of treated water decrease.
