| Along with the urbanization rate of our country accelerating and the continuous expansion of urban size, the contradiction between lacking of water resources and urban waterlogging is becoming increasingly prominent. Under the background of the sustainable development of city, how to reasonably use water resources in urban road design and construction gradually become an important way to ease water shortages and urban water-logging drainage. It seems particularly urgent to realize rainwater infiltration and efficient use for the city road by the scientific research on urban road and square storm-water ecological drainage scheme. Practical experience indicates that reasonable scheme of urban road drainage have an important influence on development and environmental improvement of the city.In face of the question that the current discharge mode of storm-water in urban road and square is not conducive to alleviate the problem of city flood and water resource shortage, the paper analyses the "storm-water drainage appropriate" of form the road sections, lane and pavement materials, road plaza green space construction. On the basis of engineering practice, through a number of related research results and practical engineering inspection, analysis, the author summarizes the related research results and concludes that the current theoretical research in urban ecology road storm-water discharge is still inadequate. The paper studies the eco-city road storm-water discharge design ideas, infrastructure systems, and related system in depth, and then presents innovative design solution of eco-city road square rainwater drainage system. At the same time, with the storm-water discharge of East Cultural Park area of Suizhou, the paper studies the connection among the new scheme, the city rainwater drainage system and landscape. The results show that, all of the concave greenbelt in road, plaza paving and planting, new material of roadways and sidewalks are not only beneficial to the city drainage, can also improve the city drainage system and landscape, create a good environment of city, and promote the natural ecological harmony. |
