上海市城市道路雨水口现状及存在的问题

Current Situation & Existing Problems of Urban Gullies in Shanghai

对上海市现状道路雨水口进行分析发现,现状雨水口存在建造工期长、不环保、质量差以及没有收集固体垃圾和防臭气外逸功能等缺点。上海市现有雨水口的设计标准偏低,孔口过水面积偏小,导致雨水口泄水量较低。需要提高其设计标准,并对不符合标准要求的现状雨水口进行优化改造,以保障城市排水系统的安全。

Through the analysis of current situation and problems of the gullies of Shanghai urban road,the existing gullies have the following shortcomings: a long construction duration,environmental damage,poor quality and lack of solid waste collection and anti-odor-escaping system,etc.Shanghai's current gullies' design is of low standard,the discharge area of orifice is too small,resulting in less rain water drainage.Design standards should be raised to optimize the gullies to ensure the safety of urban drainage systems.
