[0017] Example 1

[0018] The following detailed configuration process and application process through implementation use cases

[0019] Artificial soil for greening the roof: 15% fermented sludge, 15% desulfurized gypsum, 30% perlite, 30% straw, and 10% cinder soil. The sludge from Tianjin Jizhuangzi Sewage Treatment Plant is transported, fermented and decomposed, and air-dried to a water content of about 10%. Desulfurized gypsum is from the first thermal power plant and air-dried to a water content of 15%. Perlite is purchased from Xiqing Industrial Park, with a particle size of 2mm. -5mm, the straw is corn stalk purchased from Ninghe County, and the length is 8cm after being dried and crushed. The cinder is collected from the residential area, and the above materials are mixed according to the mass ratio, stirred and mixed evenly. Roof greening must be laid with waterproof layer, water barrier, and aquifer in accordance with the requirements. The surface is covered with artific...

[0021] The following detailed configuration process and application process through implementation use cases

[0022] The roof greening is directly covered with sod and small shrubs are planted in some areas. Artificial soil used for this greening: 15% fermented sludge, 15% desulfurized gypsum, 20% perlite, 35% straw, and 15% cinder soil. The sludge from Tianjin Jizhuangzi Sewage Treatment Plant is transported, fermented and decomposed, and air-dried to a water content of about 10%.

Abstract

The invention discloses artificial soil for roof greening and a preparation method thereof. The artificial soil for roof greening is characterized in that industrial and agricultural by-products produced in city production and perlite as a cultivation matrix are effectively used; and the materials are reasonably proportioned and effectively mixed into the artificial soil for roof greening under certain conditions. The artificial soil for roof greening is light, has high nutrient content, strong water retention and a low cost, satisfies roof greening demands, and is a good roof greening matrix.

Description

technical field [0001] The invention mainly relates to an artificial soil specially used for roof greening and a preparation method thereof, in particular to an artificial soil produced by utilizing industrial and agricultural by-products. Background technique [0002] Roof greening refers to a form of greening and gardening on the tops, roofs, and terraces of buildings and structures. As the land for greening becomes more and more tense, people gradually begin to ask for green space in the sky, and the development of green roofs and sky gardens is also getting faster and faster. The development of urban green roofs can effectively change the urban aerial landscape and increase the urban green area and visible green space. The amount of urban greening can be greatly expanded, and the urban heat island effect can be alleviated. At the same time, roof greening can also prolong the service life of the roof protection layer and reduce and prevent roof leakage. [0003] At prese...
