摘要
从海绵城市问题导向和景观环境全面提升的角度,对深圳已使用20多年的居住建筑小区——天健花园进行海绵化改造。在解决小区局部积水、地下室顶板渗漏等痛点问题的同时,改变场地径流组织,重塑景观格局,将海绵城市技术融入景观方案,通过三区立体海绵设施布局,赋予庭院雨水自然积存、滞、蓄、净化功能,形成丰富的雨趣文化。通过薄型下凹绿地和轻质透水铺装等技术创新,解决地下室顶板荷载限制下海绵设施设置问题。对雨水总排口的长期监测表明,改造后海绵城市年径流总量控制率从约17%提升至大于65%,是老旧小区宜居改造和海绵城市达标改造的一次成功探索。
Tianjian Garden,a 20-year-old residential quarter in Shenzhen has been renovated into a sponge residential area from the perspective of problem orientation and overall improvement of landscape environment.While solving the problems of ponding in the courtyard and basement roof leakage,the courtyard had been endowed with functions of natural storage,stagnation and purification of stormwater to create more fun by a three-dimensional sponge layout including change of site runoff routine,reshape of landscape pattern,and integration of sponge city technology with landscape.Innovative technologies like thin sunken green land and light permeable pavement have been used to solve the problem of setting sponge facilities under the load limit of basement roof.After long-term monitoring of the main stormwater outlet,the local total annual runoff control rate has been raised from about 17%to above 65%,which is a successful exploration of livable and sponge reconstruction in old residential quarters.
