高架桥雨水收集利用系统研究

Study on Rainwater Collection and Utilization System of Viaduct

常见的高架桥雨水系统有引流系统、海绵系统等。为解决高架桥下绿化带灌溉问题,设计了一种雨水收集利用系统。该系统充分利用高架桥桥面雨水对桥下绿化带进行浇灌,减少了市政管网的建设费用,降低城市道路运营维护成本。自该系统应用于实际工程中,经过一年多的使用,系统运行良好,桥下绿化带生长茂盛,达到了理想的效果,可供今后类似工程参考和借鉴。

The common water sprinkler systems of viaduct are the drainage system, sponge system and so on.In order to solve the problem of green belt irrigation under the viaduct, this paper introduces a rainwater collection and utilization system. This system makes full use of rainwater from the viaduct deck to irrigate the greenbelts under the viaduct, decrease the construction cost of municipal pipeline network, and reduce the operation and maintenance cost of urban roads. After more than one-year service of this system used in the practical projects, its operation is good and the green belt grows better to achieve the ideal effect, which can be referred for the similar projects in the future.
