不同类型透水铺装基层结构对雨水径流量控制效果研究
Control Effect of Different Types of Permeable Pavement Base Structure on Rainwater Runoff
为研究不同透水铺装基层结构对雨水入渗效果的影响,本文构造了两种透水铺装物理模型,这两种透水铺装分别采用再生骨料与普通级配碎石作为基层结构;开展了三种不同降雨强度下的透水铺装雨水入渗过程的模型试验。试验结果表明:在三种不同降雨强度下,再生骨料基层透水铺装出现地表径流的峰现时间滞后于普通级配碎石基层透水铺装,且产生的地表径流量较小,再生骨料基层透水铺装底部出现排水的时间要早于普通级配碎石基层透水铺装;因此再生骨料基层透水铺装对提高雨水入渗速率、削减地表径流的效果更好。研究结果对实现雨水资源化利用及建筑拆除材料的回收利用等具有重要的参考意义。
In order to study the rainfall infiltration effect of different types of permeable pavement base structures, two kinds of physical models of permeable pavement are constructed in this paper. Recycled aggregate and ordinary graded gravel are used as base structure of these two different types of permeable pavement. The experiments of rainwater infiltration process of permeable pavement under three different rainfall intensities are carried out. The results show that under three different rainfall intensities, the peak time for the flow of recycled aggregate permeable pavement lags behind that of ordinary graded gravel permeable pavement, and the surface runoff generated is smaller, and the drainage time at the bottom of recycled aggregate permeable pavement is earlier than that of ordinary graded gravel permeable pavement. Therefore, recycled aggregate permeable pavement can increase the rainfall infiltration rate and reduce the surface runoff. The research results have important reference significance for the realization of rainwater resource utilization and the recycling of building demolition materials.
