A green flat-slope roof system and construction method that can operate in frost season

Abstract

The invention provides a green flat-slope roof system and a construction method that can operate in frost seasons. The roof system includes a structural layer and equipment units; wherein, the structural layer includes a root-resistance layer (100), a drainage layer (200), The water filter layer (300) and the planting layer (400); the root-blocking layer (100) is used to inhibit the root system of plants from entering the building structure, and plays an anti-seepage effect; the drainage layer (200) is used to receive the filtered water layer (300 ) of irrigation water, on which drainage pipes (630) are laid to discharge the irrigation water 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 Plants grow to create a green environment for the roof; the equipment unit includes an irrigation antifreeze device to enable irrigation at lower temperatures. The flat-slope roof system and construction method of the present invention effectively solve the problems of difficult drainage, soil erosion, pipe blockage, high cost of plant management, and difficult restoration, and produce positive effects.

Description

technical field [0001] The invention belongs to the technical field of roof greening and prefabricated buildings, and in particular relates to a green flat-slope roof system and a construction method capable of operating in frost seasons. Background technique [0002] With the large-scale urbanization process in today's society, the scale of the city continues to expand, the buildings are getting higher and higher, and the density is getting higher and higher, forming a large number of high-density "reinforced concrete forests", which play a role in regulating the greening of the urban ecological environment. As a result, the urban ecological environment has deteriorated, and many environmental problems such as the "heat island effect" and "greenhouse effect" have appeared, and the atmospheric environment and water environment have been seriously polluted. And one of the ways to improve the urban ecological environment is to open up the green space of the city and build a ga...

Problems solved by technology

[0007] In order to solve the above-mentioned problems, the inventor has carried out dedicated research and provided a green flat-slope roof system and construction method. By using an irrigation antifreeze device, irrigation can be performed at a lower temperature; by setting a specific structural layer, the problem of In the prior art, there are many layers of green roof structure, which leads to the problems of complex laying and heavy roof load; the design of the drainage layer structure is conducive to the collection and discharge of irrigation water; the improvement of the planting layer reduces soil erosion and easily causes drainage. The risk of pipeline blockage; by cultivating plants with seed pellets, the survival rate is improved and management costs are reduced; by arranging interconnected planting rows, the modular construction of the roof system is realized, thereby completing the present invention
