基于“海绵城市”理念的透水性铺装的应用研究

Application of Water Permeable Pavement Based on the Concept of "Sponge City"

透水铺装在海绵城市建设中起着非常重要的作用。传统的路面铺装阻碍了自然水的循环过程,不利于水分的储蓄与利用,是不能呼吸的道路,因此,新型透水性的铺装材料在海绵城市的建设中被广泛应用。以运城市的公园和道路为例,对各园路的铺装材料进行了调查与分析。结果表明:航天公园和体育公园透水铺装面积分别为80%和95%,其中体育公园和航天公园内主路的彩色透水混凝土铺装和塑胶铺装透水率达0.075,透水效果较佳,另外在支路上还做了路面斜坡处理,并有一些配套设施,如下沉式绿地、卵石铺装的渗水渠等,而红旗东街F标段的透水铺装只占3%,学苑路B标段主要铺装为透水砖,占总铺装面积的90%,但透水砖的透水效果不理想。综合比较四个调查地点,体育公园道路的透水性铺装及配套设施建设较全面,较好地达到海绵城市建设的要求。

The permeable pavement plays a very important role in the construction of the sponge city.Traditional pavements hinder the natural water cycle,which is not conducive to the storage and use of water,which is a path that cannot be breathed.So,the new water permeable pavement material is widely used in the construction of“sponge city”.Taking the parks and roads in Yuncheng city as an example for investigation and analysis.The results showed that the permeable area of the Aerospace Park and Sports Park were 80%and 95%respectively.Among them,water permeability of the color permeable concrete pavement and plastic pavement of the main road in the Sports Park and the Aerospace Park were 0.075,the water permeable effect is excellent,and the road slope is treated on the branch road.There are also some supporting facilities,such as the sink green space,penetration channels such as pebble pavement.The permeable pavement of the F section of Hongqi East Street only accounts for 3%.The B section of Xueyuan Road is mainly paved with permeable bricks,accounting for 90%of the total pavement area,but the permeable effect of permeable bricks is not ideal.Among the four survey sites,the water permeable pavement and supporting facilities of the Sports Park roads are comprehensive,which meets the requirements of sponge city construction.
