Rainwater ecological purification, collection and utilization system suitable for low greening rate
The invention relates to a rainwater ecological purification, collection and utilization system suitable for a low greening rate. A roof rainwater collecting unit comprises a collecting vertical pipe, a pressure discharging pipe and an energy storage pressure tee joint; the collecting vertical pipe communicates with the pressure discharging pipe; the pressure discharging pipe is horizontally laid; the collecting vertical pipe is vertically laid; an outlet of the collecting vertical pipe is connected with the pressure discharging pipe in a sealed mode and is not connected with the atmosphere; roof rainwater potential energy is utilized for pushing rainwater in the horizontally laid pressure discharging pipe, so that the discharged rainwater has pressure, roof rainwater collected by the collecting vertical pipe has certain potential energy, the burial depth of the tail end of the pressure discharging pipe is reduced, and the burial depth cost of the pressure discharging pipe is further saved; and due to the simple structure and the high reliability, the popularization is easy.
本发明涉及一种适用于低绿地率的雨水生态净化和收集利用系统。屋面雨水收集单元包括收集立管、压力排放管以及蓄能压力三通，收集立管与所述压力排放管之间连通，压力排放管水平铺设，收集立管竖直铺设，所述收集立管的出口与所述压力排放管密闭相连，未与大气相连，将屋面雨水势能利用，用以推动水平铺设的所述压力排放管中的雨水，以使得排放的雨水具有压力；使得收集立管收集的屋面雨水具有一定势能，实现了压力排放管末端埋深减少，进而节约压力排放管道埋深成本，且由于结构简单可靠性高，易于推广。
