Problems solved by technology

[0007] 2) Too many artificial materials are used, such as the invention of "inorganic cultivation substrate for greening". The firing of artificial materials such as ceramsite requires a lot of energy, which causes environmental pollution and does not conform to the concept of environmental protection
Now, the country prohibits the use of clay bricks (red bricks) in urban construction, which results in the clay bricks produced when a large number of old buildings are demolished cannot be recycled as wall materials in the city

Abstract

The invention relates to a roof greening system and greening method. The roof greening system comprises a drain layer composed of a plastic water retention drain plate, a filtering water retention layer composed of a filtering water retention blanket made by waste and old cloth material, a plant layer composed of composite base material made by main materials of construction waste and a vegetable layer composed of the family crassulaceae. The novel roof greening system provided by the invention is reasonable in hierarchy, is proper in material selection and has the characteristics of drought resistance, light weight, environmental protection, heat preservation heat insulation and low cost. The invention uses a great amount of construction waste brickbat and household garbage waste and old cloth material, is beneficial to disposing over-growing urban solid waste and realizes recycling of resources.

Description

technical field [0001] The invention belongs to the field of roof greening, and in particular relates to a novel roof greening system which utilizes a large amount of solid waste. technical background [0002] Extensive green roofs (extensive green roofs) is a roof greening technology that has emerged and developed in Europe in recent years. Since sedum-based sedum plants are planted in the flat, it has light load and does not need to reinforce the substructure (especially It has become the main form of roof greening due to its advantages of no need for management in the later stage and low cost. [0003] The structure of the green roof is generally divided into waterproof layer, drainage layer, filter layer, planting layer and vegetation layer or waterproof layer, filter layer, planting layer and vegetation layer. The drainage layer generally uses materials with large particles and large voids, such as ceramsite, gravel, etc., to drain excess water; the filter layer genera...
