Description

A kind of Green Roof structure with rainwater reserve capability
Technical field
The present invention relates to roofing retaining, technical field of drainage, particularly to a kind of green room with rainwater reserve capability Roof construction.
Background technology
Along with the quickening of urbanization process, area is or not the waterproof underlying surface in city (roofing, road, square and parking stall etc.) Disconnected expansion, thus 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, causes the most each big city big flood to take place frequently, and the life to people creates seriously Impact, the oldest city uses combined drainage system mostly, also affects the stability of animals and plants habitat simultaneously.Roofing conduct The important component part of the waterproof underlying surface in city, plays a critically important role in rainfall runoff, and in city Occupied area is relatively big, is up to 40-50% as shopping centre roofing accounts for the ratio of the city waterproof underlying surface gross area;And due to room The corrosion product of face material itself is by rain drop erosion, containing a large amount of polluters in roof runoff.Green Roof is urban area In the special Land cover types of a class, compared with waterproof underlying surface, Green Roof has a lot of ecological functions, the most 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..Green The major function on look roof, for expanding Urban Green Spaces and green areas, reduces urban heat land effect, improves urban ecology also Can effectively cut down Rainfall runoff.Runoff is cut down and is mainly stayed and be detained by holding the suction-operated of rainfall by Green Roof Rainwater, delays runoff to produce the time, has cut down crest discharge and total runoff generation amount.As time goes on, due to its environment Benefit, Green Roof will become popular building products, but, their high cost will be the factor of a restriction.General feelings Under condition, the expert of Green Roof thinks, high cost mainly due to material be by crane be raised to roof, expensive labour and The reasons such as high insurance premium cause.Additionally, the mass ratio of Green Roof is relatively big, this cause post, beam, plate design comparison important, Thus result in more expensive structure.Therefore, how to introduce novel light material, be the hot issue of this area research.
Summary of the invention
It is an object of the invention to for above-mentioned existing problems, it is provided that a kind of Green Roof knot with rainwater reserve capability Structure, this Green Roof can improve the accumulation to rainwater, detergent power.The another kind of purpose of the present invention is to provide a kind of green room The manufacture method on top.
Technical scheme:
A kind of Green Roof structure with rainwater reserve capability, including the vegetable layer arranged from top to bottom, soil horizon, mistake Filtering layer, water-storage-drainage layer, moisturizing layer and waterproof layer, described vegetable layer is sun-proof, drought-enduring, the herbaceos perennial Fo Jia of happiness sun Grass, plant is away from for 4-6cm, and line-spacing is 8-10cm;Described soil horizon is the mixture of light sandy loam, fertile soil and vermiculite, mixed In compound the mass percent of each component be fertile soil 30-50%, vermiculite 20-25%, light sandy loam be surplus, soil horizon thickness For 15-20cm;Described filter course be can the polyester fiber non-woven fabric of permeable filtration again, filter course is laid on soil horizon Under, during laying, the effective width of overlapping the slot is 10-20cm, and extends to below upper soll layer at 5cm to building side wall;Described Water-storage-drainage layer is the 30-60mm concavo-convex drain bar of thickness PE polyethylene of light weight, anti-high pressure, good air permeability;Described moisturizing layer is The moisturizing blanket of thickness 20-30mm, without overlap joint during laying, arranged adjacent is closely;Described waterproof layer is polymer modification drip Blue or green root resistant waterproof roll, first clears up dust and the position of bubbling on the water layer of place where troops were originally stationed, then brushes 881-aqueous basic unit during construction Inorganic agent, then brush polyurethane water-proof paint 2-4mm, finally paste the ARC-700 polymer modified asphalt that thickness is 4-6mm resistance to Root puncture waterproof roll.
The technical Analysis of the present invention:
Heretofore described vegetable layer is sun-proof, drought-enduring, the herbaceos perennial of happiness sun, the most attractive in appearance, moreover it is possible to alleviate Tropical island effect, improves air quality, by retaining and evaporation plays a significant role regulation rainfall runoff;Described soil horizon is not intended for Answer nutriment and water, hot property and water conservation, and, it also provides space for plant root growth and reinforcement;Described filtration Layer is for preventing planting soil small particles and nutriment from outflowing with water, and blocking drainage pipeline;Described water-storage-drainage layer improves the logical of matrix Vaporous condition, discharges rapidly excessive moisture, effectively alleviates instantaneous pressure, and can store rainwater and be used for plant growth;Described moisturizing Layer is the flexible cover sheet of protection waterproof layer, preserves moisture for vegetation, can be mutually complementary with water-storage-drainage layer, anti-dry early, growth promotion;Institute Stating waterproof layer can protect roof not by rain erosion, it is possible to prevent root system of plant from puncturing.
The invention has the beneficial effects as follows:
1, economize the land resource, increase green coverage
Building is carried out vertical greening, builds Green Roof, make greening to spatial development,.Roof greening almost can be with Homalographic green building thing occupied area, and add the stereoscopic level of urban afforestation, increase Urban green land cover rate, improve Urban environment;
2, beautify the environment
Green Roof can make city more natural with the environment around the skyscraper of beautifying city, and more hommization is green Roof makes greening and building combine together, forms unique urban look, is beautiful scenery, one, modern metropolitan cities;
3, tropical island effect is reduced
The origin cause of formation of city hot island phenomenon and atmosphere pollution, the release of production activity energy, high building plot ratio, water body be distributed, The many factors such as vegetation and underlying surface type are relevant, and the phenomenon of the tropical island effect in city exists for a long time, increase the greening face in city Long-pending is one of effective way alleviating tropical island effect, and Green Roof is the effective ways of degraded urban heat land effect and commonly uses Way;
4, storm runoff is reduced
Due to the fast development in city, city impermeable surface layer increases, thus reduces rain infiltration, the guarantor of Green Roof Outlet capacity, contributes to controlling the quantity of runoff water, and compared with common roof system, vegetation roof can reduce the speed of runoff flowing Degree, makes city storm sewerage have time enough to process the transport of runoff, thus reduces the danger that flood occurs Danger;
5, air pollution is reduced
Generally there is the noxious material of higher level urban area in atmosphere, and urban vegetation may partly solve air pollution To be reduced to acceptable level, it is to control temperature change that Green Roof reduces air pollution method, reduces refrigeration required The energy, thus reduce the carbon dioxide of power plant release, additionally photosynthesis of plant absorbs the carbon dioxide in air.
