Description
Technical Field
The invention belongs to the field of buildings, relates to a roof greening, intelligent irrigation and energy-saving water purification technology, and particularly relates to a solar automatic irrigation type water-retaining and water-cleaning green roof system.
Background
A green roof may be defined simply as "vegetation cover placed over an artificial building". The early green roof is mainly constructed to meet the aesthetic requirements of people, and the modern green roof has both simple aesthetic functions and environmental benefits. Modern green roofs are constructed by consciously laying a plurality of structural layers under plants and planting substrates to form a complete structure. Most green roofs have similar structures and are in direct contact with the roof panels, and the construction layers from the roof panels to the top are as follows: waterproof layer, drainage blanket, filter layer, planting matrix layer and plant.
The construction of the green roof reasonably utilizes the upper space of the city, beautifies the building environment of the city, and can bring numerous ecological environmental benefits to the city, such as relieving the urban heat island effect, promoting the building to cool and save energy, controlling and utilizing urban rainfall flood, reducing noise and air pollution, enriching the variety of the city and the like. At present, under the background of vigorously advocating the construction of sponge cities in China, as a main engineering measure for controlling the source of urban rainfall flood, green roofs are popularized and applied more and more in various places.
Although the green roof has high rainwater interception rate even does not produce flow for the small rainfall events with high occurrence frequency, the green roof has poor effect on the large rainfall events with low occurrence frequency. The reason is that the rainwater storage capacity of the green roof is effective, and excessive rainfall runoff still leaves the roof to cause pressure on an urban pipe network system; for green roofs with high-nutrient planting substrates, the problem of leaching of nutrient substances can be caused, and the roof rainwater runoff flowing to an urban pipe network system brings non-point source pollution. In addition, the survival of plants on the green roof is an important guarantee that the green roof can play a role in various ecological environmental benefits (such as interception and transpiration of rainwater runoff, cooling and humidification, carbon fixation and release and the like), and particularly in northern arid regions or southern high-temperature cities, when extreme weather events such as drought and water shortage cannot be avoided, irrigation on the green roof is very necessary to maintain the survival of the plants.
