高架路下绿化浇灌新方式探索

Exploring new methods of greening and irrigation under elevated roads

随着城市的发展,高架路下绿化质量由于环境恶劣,植物长势欠佳。为改善高架路下绿化生存环境、提升生态功能,需寻找新的浇灌方式,可设计一种新式雨水分离收集器收集高架路上的雨水,并通过埋入地下的多孔管根据渗透原理为下侧绿地提供雨水浇灌。且设置二重溢流管,防止雨水过多造成溢流进而污染环境。该方法既能浇灌绿地,又能使多余的雨水排入市政雨水管网,只增加极少成本就能极大地改善植物的生存环境,使生态功能进一步提升。探索新的浇灌方式,改善绿化环境,有利于绿地自源头消减城市的径流污染,提升绿地的减洪效果和绿化的生态效果。

With the development of the city,the green quality under the viaduct is not good because of the bad environment.In order to improve the green living environment under the viaduct and enhance the ecological function,it is necessary to find a new watering method.A new rainwater separation collector can be designed to collect the rainwater on the viaduct and provide rainwater watering for the green space under the viaduct through the porous pipe buried in the ground according to the infltration principle.And set up two overflow pipes to prevent excessive rain caused by overflow and pollute the environment.This method can not only irrigate the green space,but also discharge the excess rainwater into the municipal rainwater pipe network,which can greatly improve the living environment of plants and further improve the ecological function with only a small increase in cost.Exploring new irrigation methods and improving green environment is conducive to reducing urban runoff pollution from the source of green space,improving the flood reduction effect of green space and the ecological effect of green space.
