- Title:
- Design Key Points of Terminal Regulation and Storage Project of Combined Drainage System in Central Urban Area of Tianjin
- 摘要:
- 天津市中心城区部分区域为合流制排水系统,无法改造成分流制排水系统,通过在合流制排水系统末端修建调蓄池,减少合流制排水系统末端入河溢流污染物量和溢流频率,降低合流制排水系统溢流对海河的污染。调蓄池设计标准为25 mm降雨量,总调蓄池容积为100 000 m3,考虑利用现有转输管道的调蓄容积,经计算,新建调蓄池的调蓄容积为60 000 m3。根据现有合流制排水系统的布局,针对中心城区用地紧张的现状,调蓄池主体结构选址于系统末端附近的河道下方,采用全地下式封闭设计,调蓄池修建完成后上部恢复周边绿化及现状河道。
- Abstract:
- Part of the central urban area of Tianjin is a combined drainage system, which cannot be modified into diverted drainage system. By building storage tanks at the end of the combined drainage system, the overflow frequency and flow of the combined drainage system can be decreased, and the pollution of the combined drainage system overflow to the Haihe River can be reduced. The design standard of the storage tank was 25 mm rainfall, and the total volume of the storage tank is 100 000 m3. By considering the storage capacity of the existing transfer pipeline, the storage capacity of the new storage tank was determined as 60 000 m3. According to the layout of the existing combined drainage system and the current situation of land shortage in the central urban area, the main structure of the storage tank was located below the river channel near the end of the system, and the whole underground closed design was adopted to restore the surrounding greening and current river course in the upper part after the construction of the storage tank.
