Problems solved by technology

However, most of the planting roofs in the prior art cannot meet the actual needs, and the waterproof layer is easily pierced by the root system, resulting in water leakage and water seepage, and the matrix layer located on the drainage layer is easy to lose with water, and the plant growth is not good.

Embodiment Construction

[0016] In order to further disclose the technical solution of the present invention, the implementation mode of the present invention will be described in detail in conjunction with the accompanying drawings: figure 1 As shown, a roof greening structure includes a roof base 1 and a waterproof layer 2, a protective layer 3, a drainage layer 5, a substrate layer 7, a planting layer 8, and a layer between the protective layer 3 and the drainage layer 5. A root-separating layer 4 is provided, and the root-separating layer 4 is a PVC stereotyped hydrophobic sheet, and its main function is to prevent the root system of the plant from damaging the waterproof layer. Between the drainage layer 5 and the matrix layer 7, there is an insulating layer 6, the insulating layer 6 is a non-woven fabric or a geotextile, and the overlapping length of the cloth is more than 200mm, and the main function is to prevent the loss of the planting soil and the organic medium. Before covering the matrix ...

Abstract

The invention discloses a roof greening structure which comprises a roof substrate as well as a waterproof layer, a protective layer, a drainage layer, a matrix layer and a planting layer that are arranged on the roof substrate, wherein a root separating layer is arranged between the protective layer and the drainage layer, and an earth separating layer is arranged between the drainage layer and the matrix layer. According to the roof greening structure, the root separating layer is made of PVC (polyvinyl chloride) sizing hydrophobic board, so that the root of a plant is prevented from damaging the waterproof layer; and non-woven fabrics or geotextile is paved on the drainage layer as the earth separating layer, so that earth for growing and organic medium can be prevented from erosion.

Description

technical field [0001] The invention relates to a roof structure, in particular to a green roof structure used in the construction field. Background technique [0002] The roof is regarded as the fifth facade of the building and is an important element that determines the outline of the building. As the main type of vertical greening, roof greening has shown great vitality since it was promoted in the United States in 1959. Roof greening can increase the area of ​​urban green space and improve the living environment of human beings; improve urban high-rise buildings with natural gardening landscape; improve the urban heat island effect caused by various exhaust gas pollution; open up human greening space, build garden cities, and improve people's living conditions Conditions, improve the quality of life, and beautify the urban environment, and improve the ecological effect is of great significance. At present, the new concept of environmental protection and energy-saving b...
