Research and Application of Ecological Outdoor Ground Structure with Composite Water Storage and Drainage Function

In order to solve the problems of surface runoff increase, water accumulation in rainy days and urban heat island effect, an ecological outdoor ground structure with composite water storage and drainage functions was studied and applied in this paper. Through the comprehensive design of road ground, road inspection well, garden inspection well and drainage pipe network, it can quickly store and drain ground water, alleviate the urban heat island effect, realize plant infiltration irrigation, and achieve the purpose of saving water and energy.
