Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3 shows, roof drainage of the present invention, including the frame body 1 that upper end is opening, cloth tank 2,
Water pump 3, green plants 4, horizontal drain pipe 5, vertical drainage pipe 6, overflow pipe 7, the inside of frame body 1 sets gradually from top to bottom
For cover layer 11, nutrient matrix layer 12, impervious barrier 13, reservoir bed 14, cloth tank 2 being provided with water distributing pore, cloth tank 2 is fixed on
On the side of frame body 1, and being positioned over the top of layer 11, green plants 4 is planted on nutrient matrix layer 12, and water pump 3 can be by
Water in reservoir bed 14 is delivered in cloth tank 2；Arranging porose on reservoir bed 14, overflow pipe 7 is vertically fixed in hole, horizontal row
Water pipe 5 one end is connected with overflow pipe 7, and the other end is connected with vertical drainage pipe 6.
During rainfall, rainwater drops in frame body 1, and rainwater passes cover layer 11, nutrient matrix layer 12, impervious barrier 13, can
Being stored in reservoir bed 14, when without rainfall, the water in reservoir bed 14 is delivered in cloth tank 2 by water pump 3, by cloth tank 2
On water distributing pore green plants is watered, use rainwater green plants is watered, water resource is recycled, money
Source utilization rate is high, reduces the number of times of manual watering green plants simultaneously, reduces green plants operational and administrative expenses；And excess
Rainwater is emitted in sewer pipe by overflow pipe 7, horizontal drain pipe 5, vertical drainage pipe 6, it is ensured that the load of building roof
In allowed band, cover layer 11, nutrient matrix layer 12, impervious barrier 13, reservoir bed 14 have certain cushioning effect to rainwater, storage
Water layer 14 can store certain rainwater, when rainfall is bigger, reduces the Rainfall runoff of unit interval, reduces rainwater to downcomer
The impulsive force in road, improves rainwater emission effect.
In order to ensure the intensity of frame body 1 and reduce the carrying of building roof platform 9, frame body 1 is made up of plastic plate
Outer wall and be positioned at the metallic framework of outer wall inner surface, plastic plate reduces the weight of frame body 1, and metallic framework ensures frame body 1
Strength and stability.
Cover layer 11, nutrient matrix layer 12, impervious barrier 13 purpose are to meet the growth requirement of green plants 4, green plants 4
The plant that the most drought-resistant ability is strong.The effect of nutrient matrix layer 12 is to provide necessary nutrient raw material for green plants 4 growth,
Nutrient matrix layer 12 can use original soil, sand, thin wood flour to form, and volume ratio is 6:3:1, thickness 20cm.The effect of cover layer 11: one
Be prevent material moisture content in nutrient matrix layer 12 quickly, excess evaporation and the cracking that hardens, two is to prevent in nutrient matrix layer 12
Material run off by rain drop erosion, three is that green plants 4 has been produced fixation.Cover layer 11 uses particle diameter at 0.5-
Rubble in the range of 1.0cm, has gap, thickness 5cm between rubble, gap is flow through for water, rubble low cost, intensity
Height, using effect is good.The effect of impervious barrier 13: one be in nutrient matrix layer 12 material install, prevent material drop to storage
In water layer 14, two is to store certain moisture in the gap in impervious barrier 13, it is ensured that the growth of plant.Impervious barrier includes particle diameter
Basalt fragment in the range of 5-10cm, activated carbon, sand, organic matter, volume ratio is 2:3:3:2, has between basalt fragment
Having gap, activated carbon to have aperture, between military rock fragment, the porosity with activated carbon is 50%, and average pore size is 100 μm-1mm
Between, military rock fragment and activated carbon have a large amount of hole and can save more moisture, play water holding ability, and sand and organic
The main purpose of matter is to allow form capillary tube in impervious barrier 13, in order to form capillarity extra-nutrition layer in impervious barrier 13
Water requirement.For the ease of the installation, fixing of impervious barrier 13, the inside of frame body 1 is additionally provided with wire netting panel, wire netting panel
It is fixedly installed between impervious barrier 13, reservoir bed 14.Material in impervious barrier 13 is arranged in wire netting panel, simple to operate.
Further, the inside of frame body 1 is additionally provided with drainage screen, and drainage screen is arranged between nutrient matrix layer 12, impervious barrier 13 admittedly,
Drainage screen prevents the loss of the material in nutrient matrix layer 12 further.
Water pump 3 is preferably immersible pump, and immersible pump is positioned in water, and no matter the water yield in reservoir bed 14 how, all can ensure
The using effect of water pump 3 and safety.
In order to prevent the rainwater infiltration of reservoir bed 14 to building interior, building causing damage, the present invention is at frame body 1
Base plate on be provided with water proof rubber plate.
As shown in Figure 4, Figure 5, the present invention also provides for a kind of Green Roof, including roof drainage system 8, roofdeck 9, room
Top drainage system 8 is arranged on roofdeck 9, and roof drainage system 8 is made up of multiple roof drainages, roof drainage system
Cloth tank 2 in 8 is arranged side by side, and is interconnected, and the reservoir bed 14 in roof drainage system 8 is arranged side by side, and is interconnected.
By being arranged side by side by the cloth tank 2 in roof drainage system 8, cloth tank 2 connects, in roof drainage system 8
Each roof drainage in green plants 4 all can water simultaneously, reach the maximum utilization of resource, roof simultaneously
Reservoir bed 14 in drainage system 8 is arranged side by side, and is interconnected, and the water in reservoir bed 14 can share.
Area according to roofdeck 9 is different, it is ensured that the emission effect of rainwater, can arrange multiple room on roofdeck 9
Top drainage system 8, mutual roof drainage system 8 be spaced apart 50cm.
In sum, the roof drainage of the present invention and Green Roof, simple in construction, easy construction, low cost, practicality
