Functional rainwater garden suitable for sponge cities
The invention discloses a functional rainwater garden suitable for sponge cities. The functional rainwater garden suitable for the sponge cities comprises multiple stages of baffling areas which are sequentially connected in series and are gradually decreased in height, the multiple stages of baffling areas comprise a first-stage baffling area, a plurality of middle-stage baffling areas and a last-stage baffling area, wherein the first-stage baffling area and the middle-stage baffling areas are sequentially provided with a first water storage layer and a first covering layer from top to bottom, the last-stage baffling area is sequentially provided with a second water storage layer, a second covering layer, a planting soil layer, a medium sand filtering layer, geotechnical cloth, a storageand seepage layer, a gravel drainage layer and a seepage pipe from top to bottom, the first covering layer and the second covering layer contain gravel and construction waste particles, and the storage and seepage layer is made of construction waste. According to the functional rainwater garden suitable for the sponge cities, the construction waste is used for construction of the covering layers and the storage and seepage layer so that the stacking problem of the construction waste can be solved, the disposal cost is saved, environmental pollution is reduced, moreover, a greenbelt can be usedfor stopping and storing rainwater for infiltration on site, then the rainstorm runoff peak value and rainwater drainage are reduced, and underground water recharging is increased.
本发明公开了一种适用于海绵城市的功能型雨水花园，包括依次串联且高度逐级递减的多级折流区，多级折流区包括第一级折流区、若干个中间级折流区和最后级折流区，其中第一级折流区和中间级折流区自上而下依次设置第一蓄水层和第一覆盖层，最后级折流区自上而下依次设置第二蓄水层、第二覆盖层、种植土层、中砂过滤层、土工布、储渗层、砾石排水层及渗水管，第一覆盖层和第二覆盖层包含砾石和建筑垃圾颗粒，储渗层采用建筑垃圾；将建筑垃圾用于覆盖层和储渗层的建设，不但可以解决建筑垃圾的堆放难题，节省处置费用，减少环境污染，而且可利用绿地滞蓄雨水就地入渗，减小暴雨径流峰值和雨水外排，增加对地下水的回补。
