A green flat slope roof system and construction method

Abstract

The invention provides a green flat slope roof system and a construction method. The roof system includes a structural layer; ); the root-resistance layer (100) is used to inhibit the plant root system from entering the building structure, and plays an anti-seepage effect; the drainage layer (200) is used to receive the irrigation water of the filtered water layer (300), and a drainage pipe ( 630), so that the irrigation water is discharged from the roof system; the water filter layer (300) is used to filter the irrigation water passing through the planting layer (400); the planting layer (400) is used to support the growth of plants and create a green environment for the roof. A plurality of interconnected planting rows (500) are arranged on the drainage layer (200) to implement modularization of the roof system. The flat-sloping roof system and construction method of the present invention can effectively solve problems such as drainage difficulties, soil erosion, pipe blockage, high plant management costs, and difficult repairs, and produce positive effects, which are beneficial to popularization and use.

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
