渗排型透水铺装运行维护研究进展

Operation and maintenance of permeable pavement with underdrainage:A review

作为雨水源头控制措施,渗排型透水铺装具有良好的径流控制效能,可有效削减径流体积、降低和延迟径流峰值、控制径流污染。然而,大气沉降、雨水冲刷等各种因素易导致沉积物进入透水铺装并造成堵塞,进而降低径流控制效能。合理的维护措施可有效缓解透水铺装的堵塞并恢复其渗透性。综述了渗排型透水铺装在径流控制、堵塞、维护等方面的研究进展,重点分析了径流控制效能的影响因素、堵塞及维护机理,并在径流控制效能量化、堵塞缓解、维护优化等方面提出了建议。

As a stormwater runoff control measure at source,permeable pavement with underdrainage has performed well in reducing the runoff volume,lowering and delaying runoff peak flow rate,and controlling runoff pollution.However,various factors such as atmospheric sedimentation and rainfall erosion can easily make sediment enter and clog permeable pavement,lowering the runoff control efficiency.Reasonable maintenance measures could effectively mitigate clogging in permeable pavement and restore the permeability.The research about permeable pavement with underdrainage,in terms of runoff control,clogging,and maintenance,is addressed.The impact factors of runoff control efficiency and the mechanisms of clogging and maintenance are focused on the analysis.Suggestions are made for quantifying the efficiency of runoff control,mitigating clogging,and optimizing maintenance.
