The main roads of many cities are already lined with elevated roads. The width of some viaducts can reach tens of meters. Such a large viaduct can collect considerable rainwater. At present, the rainwater in the viaduct enters the rainwater drainage system, which not only wastes rainwater resources, but also increases the pressure on the downstream rainwater drainage system. Moreover, the plants under the viaduct are difficult to be irrigated by rainwater due to occlusion, and basically all are irrigated by irrigation vehicles, which is not only inconvenient, but also increases manpower and financial resources, is expensive, affects traffic and the environment, and has poor irrigation effect. At present, in some places, the drainage from the viaduct is diverted to the reservoir for irrigation, but the effect is not very good. In the season of long rain intervals, the water storage is insufficient to provide irrigation. In addition, in some existing technologies, plant watering needs to be unable to achieve reasonable automatic control, and artificial control is required for watering. In addition, in the process of collecting rainwater, the setting of the rainstorm collection system is not reasonable enough, resulting in the failure of the normal operation of the collection system. Therefore, need to develop a kind of watering system that is simple and feasible under viaduct urgently according to above-mentioned defect.

There are square or circular holes on the side of the hanging basket, and a geotextile is arranged on the inner wall of the lower part. When it rains, the rainwater is filtered by the geotextile of the hanging basket and then enters the collection pipe system. When the flow cannot meet the rainwater flow into the hanging basket, the excess rainwater overflows from the upper half of the hanging basket.

3. The utility model is equipped with a sewage valve at the bottom of the rainwater storage device, so that when the rainwater is stored, there will be sludge and other sediments at the bottom after a long period of standing, and the sewage valve will be opened within a certain period of time to discharge the sediments.

4. In the utility model, a temperature and humidity induction solenoid valve is installed in the irrigation pipe. It is determined whether to open the switch according to the temperature and humidity in the air, and the temperature and humidity are set according to the needs. When the set temperature and humidity are reached, the valve is opened for irrigation.
