[0002] In recent years, green roofs have been widely used in the field of construction engineering. However, when designing, on the one hand, it is necessary to consider preventing the plants on the green roof from being affected by floods or droughts, and on the other hand, it is necessary to consider draining rainwater from the building roof in time to prevent siltation on the building roof and forming safety hazards. Secondly, the establishment of a green roof causes certain difficulties in the watering management of the plants. It is usually considered to divert ground water to the building roof to supply irrigation water for the plants during droughts, which will greatly increase the cost of watering management. If the rainwater during the rainfall period can be effectively stored and used during the drought period, the cost of watering management will be greatly reduced. Utility Model Content
