河北省高速公路运营期雨水集蓄利用

Application of Technology of Rainwater Collection and Utilization in the Operation Period of Hebei Expressway

目前河北省高速公路密度超过法国、日本等发达国家水平，绿化养护用水问题始终困扰着各建设单位。现在河北省严重缺水与高速公路绿化养护难两个问题之间找到了很好的切入点，提出利用雨水作为高速公路沿线绿化用水供水水源的建议，并就实际建设过程中集蓄潜力的计算、集蓄方式的选择、集蓄工程的布置及雨水处理工艺等环节作了系统介绍，以供高速公路雨水集蓄利用工程建设参考。

Now, the density of expressway in Hehei is higher than that of tb.e developed countries such as France and Japan. Finding the breakthrough point to solve the water shortage in Hebei and the water used for planting maintenance of expressway, this text proposes the suggestion about using rain water as source of water supply for the affiliated facilities of expressway, and introduces the calculation of potential to collect rainwater, the selection of mode to collecting rainwater, the layout of rain-harvesting project and the treatment of collecting rainwater in the ac tual application processed, which may provide a reference for constructing a rain harvesting project in Hebei.
