Ecological roof greening structure and construction method therefor

Abstract

The invention relates to city greening development, in particular to an ecological roof greening structure and a construction method therefor. The ecological roof greening structure comprises a structure layer (1), a heat insulation layer (2), an isolation layer (3), a sloping layer (4), a leveling layer (5), a waterproof layer (6), an isolation layer (7), a protective layer (8), a root blocking layer (9), a water guide and drainage layer (10), a filter layer (11), a light soil layer (12), a soil fixation layer (13) and a greening vegetation layer (14) in sequence from top to bottom. The greening vegetation layer (14) can be used for planting or artificially planting one or more of orychophragmus violaceus, scabiosa tschiliensis, artemisia argyrophylla, radix liriopes spicatae, euonymus fortunei var.radicans and Chinese ilex. The ecological roof greening structure has the benefits of simple structure and capabilities of beautifying the environment, purifying air, improving local microclimate and restricting sand dust and hazy weather.

Description

technical field [0001] The invention relates to the technical field of urban greening development, in particular to an ecological roof greening structure and a construction method thereof. Background technique [0002] With the acceleration of urbanization in our country, the construction land is gradually eroding the limited urban green area, and "rapid expansion of urban green space" has become an urgent requirement of people. Roof greening not only has excellent cooling and heat insulation effects, but also can beautify the environment, purify the air, improve local microclimate, enrich the city's pitching landscape, and compensate the green ground occupied by buildings, thereby increasing the city's green coverage to a certain extent. It is a roof form worthy of vigorous promotion. Especially for the more sandy, dusty and smoggy weather in the northern region in recent years, greatly promoting roof greening facilities will effectively alleviate the harm caused by this n...

Problems solved by technology

The invention patents with application numbers of 200710150931.X and 201010528151.6 have solved the above problems to a certain extent, but in winter, due to the low temperature of the soil layer, some or even all the roots of the vegetation set on it will be frozen to death. In spring, vegetation needs to be replenished, increasing the economic cost of greening vegetation
