Abstract
The invention relates to experimental facilities in agriculture, in particular to an earth-pillar percolation simulating device. In the simulating device, a horizontally arranged filter tube is arranged in an earth pillar; one end of the filter tube extends out of the wall of the earth pillar to be connected with a water collecting bottle; the outer wall of the extending end of the filter tube is hermetically connected with the wall of the earth pillar; and the other end of the filter tube is sealed. The earth-pillar percolation simulating device simulates agricultural soils after being irrigated under the condition of undisturbed soil layer, and measures the water percolating capacity (percolation rate) in unit area and unit time and the content of contaminant in water percolation so as to calculate the discharge rate of the contaminant in farmland subsiding water in an area range and provide a scientific proof for agricultural subsiding water contamination preventing and controlling technology. The device has the characteristics of reasonable structure and practicability.
Description
Technical field
The present invention relates to the experimental provision of agriculture aspect, particularly a kind of earth-pillar percolation simulating device.
Background technology
Earth pillar is as a kind of soil surveying experimental provision, its primary structure is: tubular column, soil is housed in cylinder, differing heights on the bucket wall of tubular column is distributed with thief hole, according to the experiment needs, can only carry out sample analysis to the soil sample of differing heights by thief hole, then can't satisfy for the assay of the soil liquid.
Summary of the invention
The purpose of this invention is to provide a kind of earth-pillar percolation simulating device that can conveniently extract the soil liquid in the soil.
For achieving the above object, technical scheme of the present invention is: a kind of earth-pillar percolation simulating device, comprise earth pillar, it is characterized in that in earth pillar, being equipped with the percolating pipe of horizontal positioned, the wall that one end of percolating pipe stretches out earth pillar links to each other with collection bottle, the outer wall of percolating pipe external part links to each other with the sealing of earth pillar wall, and the other end of percolating pipe is airtight.
Above-mentioned percolating pipe is made up of the perforated pipe filtering material outer with being rolled in pipe.
The sealed end of above-mentioned percolating pipe is equipped with snorkel, and the lower end of snorkel is communicated with percolating pipe is interior, and the earth pillar upper end is stretched out in the upper end of snorkel.
The bottom of above-mentioned earth pillar is equipped with filtering layer, is connected with collection bottle by connecting pipe on the earth pillar wall corresponding with filtering layer.
Above-mentioned filtering layer is made up of filter and gravel.
The upper end of above-mentioned earth pillar is equipped with water replanishing device, and the water delivering orifice of water replanishing device is communicated with earth pillar is interior.
The present invention is a horizontal positioned percolating pipe in earth pillar, by percolating pipe with in the collection bottle that the solution in the different depth soil in the earth pillar is collected with percolating pipe links to each other, so just can be very easily to different depth soil layer seepage rate, the content of pollutant in the infiltration, moisture filling amount accurately, following the ooze technical parameters such as time of moisture in soil layer measured, to the agricultural land soil under the simulation original state soil layer condition after pouring water, unit area, the content of water percolating capacity (oozing rate) in the unit interval and infiltration internal contamination thing, so that extrapolate the discharge rate of the pollutant in the farmland water-break in the regional extent, for agriculture water-break pollution prevention technique provides scientific basis.Rational in infrastructure, practical characteristics that this device has.
Description of drawings
Accompanying drawing 1 is the structural representation of the embodiment of the invention 1;
Accompanying drawing 2 is the structural representation of percolating pipe of the present invention;
Accompanying drawing 3 is the A-A cut-open view of accompanying drawing 2 of the present invention.
Embodiment
As shown in Figure 1, 2, 3, in earth pillar 1, required according to experimental study, difference plan depth level in earth pillar is placed with two percolating pipes 2, the right-hand member of each percolating pipe stretches out the wall of earth pillar, is connected with collection bottle 6 by connecting pipe 7, and the outer wall of percolating pipe and the wall of earth pillar are tightly connected.Because percolating pipe is embedded in the soil layer inside in the earth pillar, be subjected to the fine and close influence in soil aperture, there is negative pressure to produce in the percolating pipe, influence and ooze out freely flowing out of water sample in the soil.Therefore, convenient for ease of the metering of oozing out water sample, at the left end of percolating pipe snorkel 3 is installed, the earth pillar upper end is stretched out in the upper end of snorkel, communicates with atmosphere.Bottom at earth pillar is equipped with filtering layer, and filtering layer is made up of filter 4 and gravel 5, is connected with collection bottle 6 by connecting pipe 7 on the earth pillar wall corresponding with filtering layer.Give the amount of pouring water in the earth pillar for the ease of metering and control, in the upper end of earth pillar water replanishing device 8 is installed, this water replanishing device is a mariotte flask, and its water delivering orifice is communicated with earth pillar is interior.Percolating pipe is by perforated pipe 2-2 and be rolled in the outer filtering material 2-1 of pipe and form, filtering material can be selected nonwoven fabrics for use, has solved soil particle in the earth pillar like this and has stopped up the problem of percolating pipe with leakage water, makes the water sample maintenance in the strainer tube limpid simultaneously.
At the trial, the soil liquid in the earth pillar is by behind the filtering material, enter in the percolating pipe, enter then in the collection bottle 6, the area in hole and the parameters such as collecting water from runoff in each collection bottle on confluent by water replanishing device 8, the percolating pipe, just can be after pouring water to the agricultural land soil under the simulation original state soil layer condition, the content of water percolating capacity (oozing rate) in unit area, unit interval and infiltration internal contamination thing, so that extrapolate the discharge rate of the pollutant in the farmland water-break in the regional extent, for agriculture water-break pollution prevention technique provides scientific basis.
