Anti-freezing modular lightweight green slope roofing system and construction method thereof

Abstract

The invention provides an anti-freezing modular lightweight green slope roofing system and a construction method thereof. The roofing system includes a structural layer and an equipment unit. The structural layer from the bottom up includes a root barrier layer (100), a water filtering layer (200) and a planting layer (300), wherein the root barrier layer (100) is used for inhibiting plant roots from entering a building structure and plays a leakage prevention effect; the water filtering layer (200) is used for filtering irrigation water and draining the irrigation water out of a roofing structure; and the planting layer (300) is used for supporting plant growth. The equipment unit includes an irrigation anti-freezing device, so that automatic irrigation can be carried out at low temperatures during a frost period. A plurality of interconnected planting rows (400) are arranged on the root barrier layer (100) to implement modularization of the roofing system. The roofing system and theconstruction method thereof can effectively solve problems such as difficult irrigation during the frost period, soil erosion, pipeline blockage, high plant management cost and difficult repair, create positive effects, and are conducive to being popularized and used.

Description

technical field [0001] The invention belongs to the technical field of roof greening and prefabricated buildings, in particular to an antifreeze modularized lightweight green slope roof system and a construction method. Background technique [0002] Two-thirds of China's cities are short of water. China is trying to solve the problem of water shortage in northern cities by building large-scale water diversion facilities. And because the underlying surface of the town is too hard and too much cement is laid, the original natural ecological background and hydrological characteristics have been changed. Therefore, it is particularly important to increase the green area, reduce surface runoff, and improve water quality. [0003] Planting plants on building roofs has been used as a greening method. Green roof refers to building roofs (including roofs, roofs, balconies, etc.) or underground building roofs where plants are planted with planting soil. It does not occupy land resou...

Problems solved by technology

[0008] In order to solve the above problems, the present inventors have carried out intensive research and provided a kind of antifreeze modularized lightweight green slope roof system and construction method. By adopting irrigation antifreeze devices, irrigation can be carried out at lower temperatures; a specific structural layer is set , which solves the problem that the green roof structure has many layers in the prior art, which leads to complex laying and heavy roof load; by improving the planting layer, the risk of soil erosion and drainage pipe blockage is reduced; by using plants as seeds Pellet cultivation improves the survival rate and reduces management costs; by arranging interconnected planting rows, the modular construction of the roof system is realized, thereby completing the present invention
