Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in detail.
Referring to Fig. 1,2, assay device of the present utility model include bed surface frame 1, water-stop sheet 2, rhone 3, draining board 4,
High 60 centimetres of irony support 5, the inclination-angle regulating device 6 loaded on frame bottom.There is the row of a diameter of 2 centimetres of 3 rows on water-stop sheet 2
Water hole so that the interflow of horizontal direction can flow into rhone by water-stop sheet in soil horizon.Rhone 3 is furnished with upper lid, is used for
Prevent rainwater from falling directly into rhone, impact is produced on result of the test.The inclination-angle regulating device of 5 each foot of adjusting bracket can be passed through
6 respective height come leveling or adjustment bed body bed surface inclination angle, it is ensured that current smoothly import rhone.
Osculum 7 is provided with rhone, a diameter of 3 centimetres, is connected with drain pipe, access collecting container, it is same on draining board 4
Sample is provided with osculum, and the equal Jing drain pipies of all drainings are imported in collecting container.
It is the structural representation of Green Roof analog portion referring to Fig. 3, filter layer, soil is sequentially provided with draining board 4
Layer 9 and layer of plants 8, wherein layer of plants 8 select Herba Sedi Lineariss, and Herba Sedi Lineariss are a kind of Crassulaceae herbaceos perennials, vitality pole
By force, not only in the poor soils such as low mountain, level land, Cao Po, rock ground, and can grow where sunny or dark and damp.Soil
Earth layer 9 selects 2/3 loam and 1/3 natural peat, and thickness is 5 centimetres.Filter layer is afforested special using the special draining board 10 of greening
Draining board 10 is laid in soil bottom, afforests special draining board 10 and is all covered with geotextiles with water-stop sheet 2, to prevent soil from passing through
Osculum is lost in or blocks osculum.Water-stop sheet 2 is laid in the position between soil and rhone 3, afforests special draining board 10
There is osculum to draining with water-stop sheet 2.The water flowed out from filter layer imports collecting container by draining board.In Green Roof
In the design of structure, draining board can install plastics drainage plate so as to certain water storage function, this fully to simulate
Design.
Fig. 4 is collecting container schematic cross-section, including collecting container 12, drain pipe 13, ultrasonic distance-measuring sensor 11.Collection
Baffle forms are designed in water container, catchment area is kept apart with measured zone, measured zone water level fluctuation is reduced to measurement
Impact.
Fig. 5 is that this utility model received rainwater flows to schematic diagram.Fig. 5 illustrates possible stream after rainwater landing substantially
To.The rainfall for falling into test bed surface will be infiltrated by layer of plants and be entered soil horizon, then have directly ooze out into rhone and via
Drainage blanket enters two kinds of routes of rhone, finally comes together in collecting container.
During generation rainfall, computer is connected with ultrasonic distance sensor 11 and pluviometer, is received by computer and recorded
Real time data.Less, when not producing overland flow, Rainfall Infiltration, through soil and draining board 4, converges under draining board rainfall
Enter rhone 3；When rainfall is larger, overland flow is produced, part rainfall imports rhone by water-stop sheet 2.
The outflow point final to drop to the rainfall on plank bed of osculum 7.Rainwater is from Jing drain pipies 13 after the outflow of osculum 7
Flow into collecting container 12.Ultrasonic sensor 11 is placed in rainwater-collecting wall, is connected with computer, in real time in measurement collecting container
Height of water level, and by data incoming computer.
Principle of the present utility model is：Go out stream situation come interim in rainfall using plank bed modeling Green Roof.By
There is crown_interception to precipitation in soil, flowing velocity of the water in soil is smaller, therefore the outflow peak value meeting of Green Roof
Less than conventional roof, while outflow peak value time of origin also can be delayed.Green Roof mainly includes to the regulating and controlling effect of rainfall
1) precipitation can be received by edaphic hole；2) plant in Green Roof can be by intercepting, accumulating abatement roof runoff；
3) some moisture can be trapped in plant surface, and be returned in air by evaporation；4) by plant transpiration effect in or
Person's substrate evaporation is returned in air.Green Roof passes through soil horizon and layer of plants absorbs and intercept rainfall, can postpone
Contributing time and reduction runoff peak value.Before peak value is reached, the Rainfall runoff of Green Roof is less than exposed roof；Work as rainfall
When amount is very little, due to filtration and the barrier effect of soil horizon and plant to rainwater, Green Roof may not produce footpath
Stream；For the catchment of a small amount of rainfall or short time, the time required to reaching peak value, difference is very big, and this depends on green
The retentivity on roof.Green Roof is simulated by the assay device, the rainfall and time graph of pluviometer detection is obtained, and
In collecting container, the displacement and time graph of ultrasonic sensor detection, can be used for evaluating the effect of damming of Green Roof.
