在青岛市湖畔雅居和石沟社区老旧小区海绵化改造工程中，对当地集中短历时强降雨的气象条件,丘陵地形起伏大、局部易积水的地形以及地下水位低、土壤渗透性好的地质等特点进行了精细化分析，对径流控制、污染物负荷削减、管网排放能力、山洪控制、雨水利用、内涝防治等进行了精细化计算与设计，同时引入“微分区”概念精细化校核各LID及所在的微分区的蓄水能力与实际蓄水量，实行串联转输流量、相邻分区消纳，以避免出现低效率甚至无效率的海绵设施，系统地将保障水安全、改善水环境、修复水生态、涵养水资源、提升水景观结合为一个整体，并强化设计“渗、蓄、排”的透水混凝土路面、雨水调蓄池、旱溪、砾石沟等海绵措施，配置了耐旱、耐湿、耐阴、耐污染而且科学、生态、富有观赏性的植物。基于精细化设计,该工程实际运行效果良好。
- Abstract:
- During the sponge city construction in the Hupanyaju and Shigou communities, the characteristics of concentrated short-duration rainfall, the hilly terrain with ponding easily and the low groundwater level with good soil permeability were analyzed. The capture ratio of annual rainfall, pollutant load reduction, discharge capacity of pipeline network, control of mountain torrents, rainwater utilization and the prevention and control of water logging were calculated and designed. The concept of “micro-partitioning” was introduced, and the water storage capacity and actual water storage capacity of each LID and micro-partition were checked with refinement. The adjacent partitions were connected in series to avoid the low-efficiency or inefficiency of sponge facilities. Some aspects including the water security, water environment improvement, water ecology restoration, water resources conservation and water landscape upgrading were combined into a whole system. The measures of pervious concrete pavement, rainwater storage tank, dry stream and gravel grooves were strengthened. And then, plants that were drought-resistant, moisture-resistant, shade-resistant, pollution-resistant, scientific, ecological and ornamental were added. Based on the refined design, this project got a good performance.
