GREENING PANEL AND ROOFTOP GREENING STRUCTURE

PROBLEM TO BE SOLVED: To provide a greening panel capable of extending the irrigation range based on an irrigation pipe as much as possible regardless of the state of disposition of the irrigation pipe, and capable of preventing the root rot of plants.SOLUTION: Irrigation pipe storage grooves 4A and 4B are formed on the upper surface of the greening panel in such a way as to intersect and cross soil storage grooves 7A and 7B, and the inside of the irrigation pipe storage grooves 4A and 4B is formed to face the inside of the soil storage grooves 7A and 7B at intersections between the irrigation pipe storage grooves 4A and 4B and the soil storage grooves 7A and 7B. Discharge holes 9 are opened on the inner bottom surfaces 13A and 13B of the soil storage grooves 7A and 7B, and the inner bottom surfaces 4Aa and 4Ba of the irrigation pipe storage grooves 4A and 4B are located higher than the discharge holes 9 in the greening panel.
