摘要
固原市水资源极其匮乏,雨中内涝、雨后立刻干旱,雨量大且急。针对当地这一类气候特点,将传统的道路“海绵”化方案进行深化设计、施工,增加沉砂池、卵石、石笼等消能、过滤设施,对传统的人行步道进行结构、布局优化,增设雨水溢流设施,解决强降雨、湿陷性黄土原因造成的破坏问题,保证了海绵城市理念在湿陷性黄土地区的顺利实施,为干旱、半干旱、寒冷、湿陷性黄土地区乃至国家海绵城市建设打造一个可复制、可推广的典型模板。
Guyuan city is extremely short of water resources because waterlogging in the rain and drought immediately after the heavy and urgent rainfall.According to the local climate characteristics,The traditional"sponge"is further designed and constructed by adding energy dissipation and filtration facilities such as grit chamber,pebble and gabion,optimizing the structure and layout of traditional pedestrian footpath,and adding rainwater overflow facilities to solve the damage of traditional"sponge"caused by heavy rainfall and collapsible loess.These measures make the concept of sponge city implement in collapsible loess area successfully.It will create a typical template that can be copied and promoted in the arid,semi-arid,cold,collapsible loess areas and even the national sponge city.
