Drip irrigation type slope roof greening device and method
Technical Field
The invention relates to the technical field of roof greening, in particular to a drip irrigation type slope roof greening device and method.
Background
The roof greening can effectively improve urban environment, relieve urban heat island effect, and has the functions of noise reduction and heat preservation and heat insulation for buildings. Currently, the slope roof area in the world accounts for about 40% of the whole roof area, but in China, most old buildings comprise some new-type high-rise buildings under the influence of traditional building styles and weather conditions, and particularly in southern areas, the slope roof accounts for a larger proportion. However, over 95% of domestic roof greening is used on the skirt house roof of high-rise buildings such as hotels, office buildings, nursing homes and the like, and the flat roof of a residential area is occasionally used, but greening on the pitched roof is little and little.
Compared with a plane roof, under the same building plane area, the surface area of the slope roof skin contacting with air is larger, and more solar radiation heat can be absorbed; under the same building height, the slope roof also increases the greening area of the vertical wall surface and can absorb the solar radiation reflected by the vertical surface of the nearby building, so that the slope roof greening can not only absorb more solar radiation heat, but also reduce the radiation heat of the wall surface of the nearby building. In addition, the slope roof is changeable in shape, the fifth vertical face of the building can be shaped, and the skyline and the contour line of the city are enriched.
The technical level of domestic roof greening is low, the greening technology is relatively mature mainly aiming at plane roofs, such as garden type, covering type, planting groove type and the like, slope roof greening is limited by a bearing structure of a top layer of a building and influenced by a building vertical face, the requirements on design and construction technology are high, and the prior art can be divided into ramp type, step type and module type, but the former two types are the main types. Slope roof greening mainly has two technical difficulties, namely slippage of a plant structure layer and loss of a planting matrix, and fast roof drainage and poor water retention.
