Between 9.
In operation, sealing cover 2 is opened, the soil S for being blended with pollutant is filled in inner cavity 11 and the position of hollow cylinder 1
In on cloth 4, then the lid of sealing cover 2 is closed at the top of hollow cylinder 1；External water source is opened so that the simulation that external water source provides
The water of rainfall is sprayed at via spray head 3 on the soil S for being mixed with pollutant, open pump 10 so that underground water storage tank 8 it is true
Underground water entered in a manner of bottom horizontal flow sheet the container 71 of staving 7, the container 71 for flowing out in a manner of bottom horizontal flow sheet staving 7,
It flows back into pollution water storage tank 9 to simulate the underground water really flowed via pump 10 again；The water that spray head 3 sprays penetrates into mixing
Have in the soil S of pollutant and pollutant is made to be migrated with the sinking of dampening, the water of the simulated rainfall of the pollutant containing migration
Staving 7 is lowered by the perforation 61 of cloth 4, gravel layer 5 and perforated plate 6, drops to container 71 in staving 7 again
To enter in the underground water of the bottom horizontal flow sheet of container 71, it is mixed with the ground of the bottom horizontal flow sheet of the water of pollutant and simulated rainfall
Lower water flows out the container 71 of staving 7 via pump 10 and is transported in pollution water storage tank 9, is mixed with the simulated rainfall of pollutant
Water is sampled via contaminated soil water sampling mouth 72, is mixed with the underground water of water of pollutant and simulated rainfall via impurely
Lower water sampling mouth 91 is sampled.
It is dirty during the experimental provision energy simulated rainfall that the simulating pollution object based on the utility model migrates in soil-underground water
Migration situation of the object in soil and groundwater is contaminated, so that the transportion and transformation of pollutant is close to actual conditions, and energy
It is enough in and the pollutant of contaminated soil and the pollutant of polluted underground water is sampled.
With reference to Fig. 1, hollow cylinder 1 be additionally provided with make inner cavity 11 and external exhaust gas collection device (not shown) it is controlled connect go out

Lower water sampling mouth 91 and the connection of the inside of pollution water storage tank 9.
Hollow cylinder 1 can be transparent organic glass pipe, thus be sprayed at the soil for being mixed with pollutant convenient for observation spray head 3
The power and amount of the water of the simulated rainfall provided from external water source on earth S, and then the water of the sprinkling of adjustment spray head 3 is strong
It is weak.
Cloth 4 can prevent soil from draining to gravel layer 5 and enter the perforation 61 of perforated plate 6 through gravel layer 5 and block and wear
Hole 61.Preferably, cloth 4 is non-woven fabrics, and non-woven fabrics has excellent water repellent performance, so that water can be penetrated with form of moisture drops
Non-woven fabrics is simultaneously entered in the perforation 61 of perforated plate 6, so as to further truly simulate oozing for the rainfall for being mixed with pollutant
Saturating situation.
Perforated plate 6 can be poly (methyl methacrylate) plate, so as to which whether the perforation 61 for facilitating look at perforated plate 6 is blocked.
Staving 7 can be transparent plastic pail, thus convenient for the depth of the underground water in the container 71 of range estimation staving 7, and then
By the fluctuation of the water level of the underground water in container 71 being controlled to be maintained at reasonably with being actually consistent the control of pump 10
In the range of, avoid that the underground water in container 71 touches the lower surface of perforated plate 6 upwards, even counter spill over is mixed with pollutant
Soil S in.
Underground water storage tank 8 can be transparent plastic can, thus be convenient for visually descending the liquid level of the underground water in water storage tank 8.
It can be transparent plastic can to pollute water storage tank 9, thus convenient for the liquid level in range estimation pollution water storage tank 9.
The building block of the experimental provision migrated in soil-underground water according to simulating pollution object is (including being mixed with pollution
The soil S of object) size can be set according to geometric similarity principle.It is possible thereby to more realistically reflection pollutant is contaminated
Actual migration situation in soil.The size of the component of experimental provision migrated in soil-underground water according to simulating pollution object
It can be further based on the space of experimental implementation (especially laboratory) and convenience design.In one embodiment, hollow cylinder 1
Height be 800mm-1200mm, internal diameter 100mm-300mm；The height of staving 7 is 200mm-300mm；The height of gravel layer 5
For 2mm-5mm；A diameter of 3mm-10mm of the perforation 61 of perforated plate 6；The spacing of perforated plate 6 and container 71 is 30mm-50mm.
In addition to it is above-mentioned be sampled using the water of simulated rainfall that is mixed with pollutant via contaminated soil water sampling mouth 72,
The underground water for being mixed with the water of pollutant and simulated rainfall is sampled outside via polluted underground water sample tap 91, can also be into one
The method that step fetches earth with reference to layering, analyzes the soil after experiment.Referring for example to Fig. 2 and Fig. 3, after experiment
The soil S for being mixed with pollutant be divided into three parts, i.e. upper area, central region, lower area, then by each region
6 sub-regions, i.e. 1#-6# subregions are divided into, these subregions are respectively sampled and are detected.
