Technical field
The present invention relates to roofing water storage, technical field of drainage, more particularly to a kind of green roof system.
Background technology
With the quickening of urbanization process, area is or not the waterproof underlying surface in city (roofing, road, square and parking stall etc.)
It is disconnected to expand, so as to cause flow path surface increase, through flow velocity to be accelerated.The rainfall retentivity of urban area weakens significantly, gives
Sewerage system brings immense pressure, cause in recent years each big city big flood take place frequently, the life to people generates seriously
Influence, especially old city uses combined drainage system mostly, while also influences the stability of animals and plants habitat.Roofing conduct
The important component of the waterproof underlying surface in city, a critically important role is played in rainfall runoff, and in city
Occupied area is larger, and the ratio that the waterproof underlying surface gross area in city is accounted for such as shopping centre roofing is up to 40-50%；And due to room
The corrosion product of plane materiel material in itself contains a large amount of polluters by rain drop erosion in roof runoff.Green Roof is urban area
The special Land cover types of middle one kind, compared with waterproof underlying surface, Green Roof has many ecological functions, external a lot
Urban storm management philosophy is as a kind of potential alleviation Urban Storm Flood and the effective means of Control the Plan Pollution Sources.
Green Roof structure generally includes drainage system, root resistance system, filtration system, somatomedin and plant etc..It is green
The major function on color roof reduces urban heat land effect, improves urban ecology simultaneously to expand Urban Green Spaces and green areas
Rainfall runoff can effectively be cut down.Green Roof is to the abatement of runoff mainly by the way that the suction-operated of rainfall is withheld and is detained
Rainwater, delay runoff generation time, cut down crest discharge and total runoff yield.Over time, due to its environment
Benefit, Green Roof is by as the building products of prevalence.
