Green flat pitched roof system and construction method

Abstract

The invention provides a green flat pitched roof system and a construction method. The roof system comprises a structure layer, and the structure layer comprises a root stopping layer (100), a drainage layer (200), a water filtering layer (300) and a planting layer (400) from bottom to top. The root stopping layer (100) is used for preventing the plant root system from entering a building structure, and an anti-seepage function is achieved. The drainage layer (200) is used for bearing irrigation water passing through the water filtering layer (300), a drainage pipe (630) is laid on the drainage layer (200), and therefore the irrigation water is drained out of the roof system. The water filtering layer (300) is used for filtering the irrigation water passing through the planting layer (400). The plating layer (400) is used for supporting plant growth, and constructing a green environment for a roof. Multiple planting rows (500) capable of being interconnected are arranged on the drainage layer (200), and roof system modularization is implemented. According to the flat pitched roof system and the construction method, the problems of hard drainage, water and soil loss, pipeline blockage, high plant management cost, hard restoration and the like can be effectively solved, a positive effect is achieved, and use and popularization are benefited.

Description

technical field [0001] The invention belongs to the technical field of roof greening and prefabricated buildings, in particular to a green flat slope roof system and a construction method. Background technique [0002] Roof greening, also known as "sky garden", uses the roof, roof or balcony as a platform to expand the "fifth facade" for green space, so as to selectively grow flowers and trees, pave green grass, and build garden landscapes to achieve Aesthetic or economical purposes. After the roof is greened, because the physical properties of the green roof and the cement roof are quite different, the net radiant heat of the green roof is much smaller than that of the non-green roof. At the same time, the latent heat consumed by the green roof due to job transpiration and evaporation is significantly larger than that of the non-green roof, thereby greatly reducing the surrounding air temperature. A study by the United Nations shows that if the green roof rate of a city re...

Problems solved by technology

[0006] In order to solve the above-mentioned problems, the present inventor has carried out intensive research and provided a green flat-slope roof system and construction method. By setting a specific structural layer, it solves the problem that the green roof structure in the prior art has many layers, which leads to complex laying and The problem of heavy roof load; the design of the drainage layer structure is conducive to the collection and discharge of irrigation water; through the improvement of the planting layer, the risk of soil erosion and drainage pipe blockage is reduced; The survival rate is improved and the management cost is reduced; by arranging interconnected planting rows, the modular construction of the roof system is realized, thereby completing the present invention
