Roof greening structure

Abstract

The invention discloses a roof greening structure. The structure comprises a building house top layer, and an anti-leakage layer which is paved on the building house top layer, wherein a water storage and drainage overhead plate is arranged on the anti-leakage layer; a root separating layer is paved between the anti-leakage layer and the water storage and drainage overhead plate; a filter layer is paved on the water storage and drainage overhead plate; a planting layer is arranged on the filter layer. Through the arrangement of the water storage and drainage overhead plate, the problem caused by the greening on the basis of an impermeable layer can be solved; the water drainage is uniform and timely, the air permeability is good, the water storage and adjustment functions are better, the water storage amount is large, the weight is light, the bearing ability of buildings is greatly reduced, and at the same time, the environment is protected, the energy is saved, and the environment is benefited.

Description

technical field [0001] The invention relates to a roof greening structure, which belongs to the field of civil engineering. Background technique [0002] With the increasing popularity of high-density residential areas and high-rise residences, the area of ​​underground structures such as underground garages is increasing. In order to meet the requirements of greening, it is necessary to cover the underground structures with soil for greening. In addition, due to the increasingly serious urban heat island effect and the improvement of people's living environment requirements, roof gardens are increasingly used as auxiliary greening measures. Since most of these greening measures are carried out on the basis of impermeable buildings, it will inevitably cause the problem that rainwater cannot be infiltrated and eliminated in time. Moisture is an indispensable element for plant development. Too much water in the soil will cause plant root rot or other diseases. The air permeab...

AI Technical Summary

Problems solved by technology

Since most of these greening measures are carried out on the basis of impermeable buildings, it will inevitably lead to the problem that when there is too much rain, it cannot be infiltrated and eliminated in time.

Water is an indispensable element for plant growth. Too much water in the soil will cause plant rot or other diseases. The air permeability of the soil will become poor, which is not conducive to the growth of plants, and will also affect the safety of the roof garden.
