Abstract

The invention discloses a fabricated type passive greening system for a roof. The fabricated type passive greening system comprises a roof waterproof layer 1, an enclosing wall 2, a planting tank 4 and an drip irrigation system 3, wherein an enclosing wall waterproof layer is arranged on the inner surface of the enclosing wall; the planting tank is arranged on the roof waterproof layer; a pipeline of the drip irrigation system is arranged by penetrating through the planting tank; a drip irrigation hole 6 of the drip irrigation system is formed in the planting tank; an overflow pipe 7 is arranged by penetrating through the enclosing wall and the enclosing wall waterproof layer; and a water inlet end of the drip irrigation system is provided with a water inlet valve 5 which is electrically connected with a water level controller and a water temperature controller. According to the fabricated type passive greening system disclosed by the invention, the problems of heavy roof load, tedious construction, high maintenance cost and the like can be effectively solved, the rainwater storage capacity of the roof is increased, and absorption storage and recycling of rainwater can e achieved by virtue of a porous structure of the planting tank at the same time, and due to the design of the planting tank, the interpenetrating destructions of plant root systems to a roof structure layer can be avoided. The fabricated type passive greening system is simple to construct, good in water storage capacity, and low in maintenance cost, and is a roof greening system capable of being promoted on a large scale.

Description

technical field [0001] The invention belongs to a roof greening technology, in particular to the roof rainwater recovery and utilization technology in landscaping and sponge city construction, and relates to an assembled passive greening system for the roof. Background technique [0002] Due to the further development of the urbanization process, the urban green space has gradually decreased, and the urban ecological environment has been destroyed. With the improvement of the living standards of urban citizens, the demand for green space is also gradually increasing. Therefore, it is a direction for urban ecological transformation and improvement of greening rate to fully tap new green space in built cities. [0003] Roof greening is a new direction of urban greening that has emerged in recent years. Roof greening provides a new technical field and plane space for the increase of urban green area. At present, the technical problems in roof greening are mainly the roof load...
