【摘要】 以沈阳理工大学图书馆为具体实例,基于海绵城市理念进行雨水生态利用系统的设计。在图书馆雨水资源化上主要侧重提高土地的自然渗透能力,包括下凹式绿地和人行道成透水性铺装。实现了削峰调蓄、涵养地层、绿化植被。通过分析城市绿地不同设置形式的滞蓄暴雨径流效果。进行水量分析计算,城市雨水生态利用系统的设计后,雨水利用率达到了43.8%,雨水利用率明显提高,对于减轻市政排水管网的压力和增加土壤入渗的效果显著。更多还原

【Abstract】 Taking the library of Shenyang Ligong University as an example, the design of rainwater ecological utilization system is carried out based on the concept of sponge city. In the library rainwater resources mainly focus on improving the natural infiltration capacity of the land, including concave green space and pavement into a permeable pavement. The collection and diversion of road rainwater achieved peak shaving and storage, conservation of strata and greening vegetation. The effects of different storages of urban green space on storm water runoff are analyzed. After the design of urban rainwater ecological utilization system, the utilization ratio of rainwater reaches 43.8 %, and the utilization ratio of rainwater is obviously improved. The effect of reducing the pressure of municipal drainage pipe network and increasing soil infiltration is remarkable.更多还原
