山地城市排水防洪设计方案及要点

Design Scheme and Key Points of Drainage and Flood Control in Mountainous Cities

以重庆市协同创新区新建孵化器及周边道路项目为例,针对山地城市自然地形,解决地块建成后道路及周边雨污水收集排放,同时考虑山区泄洪通道与市政雨水相结合进行设计,并探讨了山区排水管道保护方案和管道穿越山区冲沟河道等设计要点。

Taking the new incubator and the surrounding road project in Chongqing Collaborative Innovation Zone as an example,aiming at the natural terrain of mountain cities,the collection and discharge of rainwater and sewage on the roads and surrounding area after the completion of the plot are solved.At the same time,the design is carried out by considering the combination of flood discharge channels and municipal rainwater in mountain areas.The protection scheme of drainage pipeline in mountain area and the design points of pipeline crossing the gully and river in mountain area are discussed.
