临沂市高架桥雨水收集利用探讨

Discussion on collection and utilization ofrainwater on viaducts in Linyi city

为了解决高架桥下绿化带的灌溉问题,结合临沂市双岭路高架路海绵城市改造提升建设工程,研究开发了一种新型高架桥雨水收集利用系统。该系统利用雨水收集箱和塑料模块蓄水池收集高架桥面的雨水,灌溉桥下绿化带。应用结果表明:该系统降低了市政管网建设和城市道路运营维护成本,具有操作简单、成本低、维护方便等优势,适合临沂市高架桥工程现状,对临沂市高架桥道路雨水收集系统的建设发展有着促进作用,同时对推动市区海绵城市道路建设的可持续发展,有较大的创新性与推广价值。本文成果可为国内其他城市道路海绵城市建设、雨水收集利用方面的研究与实践提供一定的借鉴。

In order to solve the irrigation problem of the green belt under viaducts,a new type of viaduct rainwater collection and utilization system is developed in combination with the sponge city renovation and upgrading construction project of Shuangling Road Viaduct in Linyi City.The system uses rainwater collection deck and plastic module reservoir to collect rainwater on the viaduct surface and irrigate the green belt under the bridge.The application results show that the system reduces the cost of municipal pipe network construction and urban road operation and maintenance,and has the advantages of simple operation,low cost and convenient maintenance,which is suitable for the current situation of the viaduct project in Linyi City,and has a promoting effect on the construction and development of the viaduct road rainwater collection system in Linyi City,and has great innovation and promotion value for promoting the sustainable development of urban sponge city road construction.The results can provide some reference for the research and practice of road sponge city construction and rainwater collection and utilization in other cities in China.
