在青島市湖畔雅居和石溝社區(qū)老舊小區(qū)海綿化改造工程中，對當(dāng)?shù)丶卸虤v時強降雨的氣象條件,丘陵地形起伏大、局部易積水的地形以及地下水位低、土壤滲透性好的地質(zhì)等特點進行了精細化分析，對徑流控制、污染物負(fù)荷削減、管網(wǎng)排放能力、山洪控制、雨水利用、內(nèi)澇防治等進行了精細化計算與設(shè)計，同時引入“微分區(qū)”概念精細化校核各LID及所在的微分區(qū)的蓄水能力與實際蓄水量，實行串聯(lián)轉(zhuǎn)輸流量、相鄰分區(qū)消納，以避免出現(xiàn)低效率甚至無效率的海綿設(shè)施，系統(tǒng)地將保障水安全、改善水環(huán)境、修復(fù)水生態(tài)、涵養(yǎng)水資源、提升水景觀結(jié)合為一個整體，并強化設(shè)計“滲、蓄、排”的透水混凝土路面、雨水調(diào)蓄池、旱溪、礫石溝等海綿措施，配置了耐旱、耐濕、耐陰、耐污染而且科學(xué)、生態(tài)、富有觀賞性的植物�；诰毣O(shè)計,該工程實際運行效果良好。
- 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.
