Zero-discharge sponge urban rainwater system
The invention discloses a zero-discharge sponge urban rainwater system. The rainwater system comprises a low-impact development system and a waterlogging prevention and control system; according to the low-impact development system, the rainwater recurrence period standard is selected through technical and economic comparison, rainwater of a land parcel is subjected to source dispersion, permeation, retention and storage through the system design, so that the purposes of organizing the rainwater and controlling the runoff are achieved; and the waterlogging prevention and control system comprises a rainwater overflow facility and a tail end regulation and storage facility, rainwater exceeding the recurrence period standard forms source overflow rainwater, and the source overflow rainwater is drained to the tail end regulation and storage facility through the rainwater overflow facility. According to the rainwater system, a traditional rainwater pipe network is replaced by a grey-green combined sponge facility, so that the construction cost is reduced; and the technical problems that a conventional sponge city is insufficient in runoff total amount control capacity, only medium and light rainfall events with high frequency can be controlled, and rainwater is still drained through a rainwater pipe canal system are solved, and finally zero rainwater drainage is achieved.
本发明公开了一种零外排海绵城市雨水系统，该雨水系统包括：低影响开发系统和内涝防治系统；其中，低影响开发系统采用技术、经济比较选择雨水重现期标准，系统设计对地块的雨水进行源头分散、渗透、滞留与蓄存，达到组织雨水与控制径流的目的；内涝防治系统包括雨水溢流设施和末端调蓄设施，超过重现期标准的雨水形成源头溢流雨水，源头溢流雨水通过雨水溢流设施被引流到末端调蓄设施。本发明采用灰绿结合的海绵设施代替了传统雨水管网，降低了工程造价；解决了常规海绵城市径流总量控制能力不足，只能控制频率较高的中、小降雨事件，仍然依靠雨水管渠系统排除雨水的技术问题，最终达到雨水零外排。
