基于弱渗水土质含渗透管的透水铺装水量控制

摘要

For the weak soil permeability area,the application effect of conventional permeable pavement needs to be improved.The effect by new type of permeable pavement with perforated pipe for runoff control was studied through experiment.Experimental results showed that the runoff appear time of permeable pavement with perforated pipe were prolonged than conventional pavement and ordinary permeable pavement, and increasing percentage is 50.0%~200.0%.The permeable pavement with perforated pipe reduce the peak flow rate increased from 9.4%to 43.7%than conventional permeable pavement.Compared with the conventional permeable pavement,the runoff depth of permeable pavement with perforated pipe was reduced by 20.83%~66.67%.The results show that in the low permeability soil area,the road surface runoff control effect of permeable pavement with perforated pipe is bet-ter than that of the conventional permeable pavement, and it would promote the weak permeable soil permeable pavement research and development.%对于土壤渗透能力较弱地区,常规透水铺装的应用效果有待提高.通过试验研究了适用于弱渗水土质的含渗透管的新型透水铺装对雨水径流水量的控制作用.实验表明:含渗透管的透水铺装比普通路面及常规透水路面的产流时间均有延长,增加百分比介于50.0%~200.0%之间;含渗透管的透水铺装比常规透水路面在洪峰流量削减方面效果显著,洪峰流量削减率提高了9.4%~43.7%;相比常规透水路面,含渗透管的透水铺装路面雨水径流深度减少了20.83%~66.67%.研究表明:在弱渗水土质地区,利用含渗透管的透水铺装对雨水径流的水量控制效果明显,优于常规透水路面,开拓了弱渗水土质地区透水铺装研发的思路.
