摘　　要：为缓解用地紧张与工程建设的矛盾,以上海中心城区某初雨调蓄池工程为例,提出了竖井初雨调蓄池及入流竖井布置形式,介绍了调蓄池冲洗、通风除臭及排空设计方案。调蓄池采用全地下式圆形竖井结构,调蓄容积4700 m^(3),内径15 m,池深33.80 m,入流采用螺旋阶梯跌水消能,池底安装智能喷射器冲洗清淤,除臭采用三段式“洗涤法+离子除臭+化学吸附”工艺,竖井主体结构采用预制管片机械化拼装,可为用地紧张的大城市中心城区及老城区建设初雨调蓄池提供参考。To address the conflict between land scarcity and project construction,this paper presented a case study of an initial rainwater storage tank project in central Shanghai,and proposed the layout of the shaft initial rainwater storage tank and the inlet shaft,along with detailed schemes for tank cleaning,ventilation,deodorization,and emptying.The storage tank utilized a fully underground cylindrical shaft structure,with a storage capacity of 4700 m^(3),an internal diameter of 15 m,and a depth of 33.80 m.For inflow energy dissipation,a spiral-step drop system was employed,while intelligent ejectors installed at the bottom of the tank facilitated washing and desilting operations.The deodorization process consisted of three processes:washing,ion deodorization and chemical adsorption.The main structure of the vertical shaft adopted mechanized assembly of prefabricated pipe segments.This design can serve as a reference for constructing initial rainwater storage tanks in central urban areas and old districts of large cities facing land scarcity.
