海绵城市的深层蓄水模式探讨

Discussion of deep water storage model of sponge city

目前,植草沟、下凹式绿地、透水铺装等均为海绵城市重要措施,但会造成暴雨后清洁困难,同时为了节省成本,地库敷土较少,还要敷设给水、消防、污水、雨水、燃气及强弱电等管线,并且还要栽花种树等,浅层蓄水空间受限,那么深层蓄水则有效地补充了浅层蓄水的不足,项目上可以实现深浅层蓄水的有效结合,达到自然循环的效果。

At present,sponge city has some measures such as grass planting ditch,concave green space and permeable pavement,but it is difficult to clean after rainstorm.At the same time,in order to save costs,there is less soil in the basement,and pipelines such as water supply,fire protection,sewage,rainwater,gas and strong and weak electricity should be laid.Besides,flowers and trees should be planted,so the shallow water storage space is limited.Then deep water storage can effectively supplement the lack of shallow water storage,and the effective combination of deep and shallow water storage can be realized in the project to achieve the effect of natural circulation.
