Description

Strengthen strutting roof ecological greening rainwater utilization structure

Technical Field

The invention belongs to the technical field of sponge cities, and particularly relates to a rainwater utilization structure for reinforcing and supporting ecological greening of a roof.

Background

Along with the acceleration of the urbanization process, the area of the urban impervious underlying surface (such as a roof, a road, a square and a parking space) is continuously enlarged, so that the surface runoff is increased, and the runoff speed is accelerated. The rainfall retention capacity of the urban area is greatly weakened, and great pressure is brought to urban drainage systems, so that flood disasters of various big cities occur frequently in recent years, and serious influence is caused to life of people, particularly, the combined drainage system is mostly adopted in old cities, and the stability of animal and plant habitats is also influenced. The roof is an important component of the urban impervious underlying surface, plays an important role in rainfall runoff, and occupies a large area in cities, for example, the proportion of the roof in a commercial area to the total area of the urban impervious underlying surface is up to 40-50%; moreover, roof runoff contains a large amount of pollutants because corrosion products of the roofing material are washed away by rainwater. The green roof is a special land covering type in urban areas, compared with an impermeable underlying surface, the green roof has a plurality of ecological functions, a plurality of foreign urban storm management concepts take the green roof as a potential effective mode for relieving urban rainfall flood and controlling non-point source pollution, the sponge city is a new generation urban rainfall flood management concept, and the sponge city is a good 'elasticity' in the aspects of adapting to environmental changes, responding to natural disasters caused by rainwater and the like, and can be called as a 'water elasticity city'. The international generic term is "low impact development storm water system construction". The roof greening system has the advantages that the roof greening area is increased at a high speed along with the development of the urbanization process, so that a system capable of compensating the defects in the aspects of autonomous water supply, beautifying and greening, collecting rainwater, conserving a lawn by using the rainwater, improving the utilization rate of water resources, realizing the integration of water storage, water supply, drainage, beautifying, greening and irrigation functions, achieving the effects of more efficient water storage, economic application, energy conservation, environmental protection and urban environment improvement, enabling the city to return to the nature, and constructing an ecological civilized city harmonious with the nature. The main functions of the green roof are to enlarge the green space and green area of the city, reduce the urban heat island effect, improve the urban ecology and effectively reduce the runoff of rainwater. The runoff is reduced mainly by the green roof through the adsorption effect on rainfall to retain and retain rainwater, so that the runoff generation time is delayed, and the peak flow and the total runoff generation amount are reduced. Over time, green roofs will become a popular building product due to their environmental benefits.
