基于海绵城市的理念,以江苏某高校校园为例,从绿色校园与海绵校园角度出发,进行雨水收集方案设计.在校园山形地貌地理环境的基础上,将校园分为东、西校区,采用分区收集雨水,并分别进行了雨水供、需水水量计算,供水计算包括建筑屋面、道路、绿地、广场及停车场的径流雨水,回用水包括建筑冲厕、冲洗道路、绿化灌溉等地方.设计方案全部采用重力流收集雨水,通过水量平衡计算表明,东、西校区收集水量均大于供水水量,采用本设计方案可提高水资源利用率.
Based on the concept of sponge city,taking a university campus in Jiangsu as an example,from the perspective of green campus and sponge campus,rainwater collection scheme is designed.On the basis of the geographical environment of the mountainous landform,the campus is divided into east and west campus,and the rainwater is collected by the zone,and the rainwater supply and water demand calculation are calculated.The water supply calculation includes building roof,road,green space,square and parking Of the runoff rainwater,reuse water,including construction flushing,washing roads,green irrigation and other places.The design scheme uses all the gravity flow to collect the rainwater.The water balance calculation shows that the water collected in the east and west school is larger than the water supply,and the water resources utilization rate can be improved by adopting the design scheme.
