Turf-covered Tibetan resident house door head

The existing roof water-proof and greening technology is used to plant the plant cover on a door head of a Tibetan resident house and improve the leak problem of the prior technology, thus the existing door head top such as an anti-seepage asbestos tile and a cement prefabricated panel is replaced and the special plant door head top is continuously used. Even though in the premise of keeping the national feature, the anti-seepage action is realized. A water-proof layer, an isolation layer, a root protection layer, a drainage layer, a filter layer and a turf layer are laid on the structure layer of the door head in turn, so as to achieve the planting requirement. The turf-covered Tibetan resident house door head keeps the Tibetan national feature and also prevents the rain from flushing and corroding the wood structure on the top of the door.
