对双层多孔混凝土滤水管、无纺布包单层多孔混凝土滤水管、单层多孔混凝土滤水管等无填砾滤水结构进行了多方案室内模拟渗流试验,在方案比较的基础上,进一步做双层多孔混凝土滤水管实井验证试验,结果表明双层多孔混凝土滤水管是适宜陕北风沙滩区粉细砂含水层的理想滤水结构。
Multi-program indoor simulation seepage test is carried out on the non-gravel water filtration structure such as double-layer porous concrete drainage pipe, non-woven bag single-layer porous concrete drainage pipe and single-layer porous concrete drainage pipe. Based on the comparison of schemes, The experiment of two-layer porous concrete drainage pipe for well test shows that the double-layer porous concrete drainage pipe is the ideal drainage structure suitable for the fine sand aquifer in northern Shaanxi sandy beach.
