Abstract
The utility model discloses a soil profile water-salt testing soil bin which is a square soil bin (1) comprising a soil bin frame (2) and left, right, back and lower side transparent bodies (3) characterized in that moisture movement of soil can be observed perspectively and has the effect that soil moist peak curves can be drawn on the transparent bodies; a front side mesh (4) is characterized by having a certain strength and being an insulator, and plays a role of supporting the pressure of the soil; a water retaining plastic film (5) at the inner side of the front side mesh prevents water and soil from flowing out from the front side mesh (4); and a water-salt testing device (6) can be used for testing the moisture change and the salinity change of the soil simultaneously. Compared with the prior art, the soil profile water-salt testing soil bin has a simple structure, can be used for drawing soil moisture peak curves and monitoring the salinity change of soil at any point simultaneously through the water-salt testing device, is simple and easy to use, and saves the cost.
Description
Technical field:
The present invention relates to the holard salt exercise test field of Agricultural Water-Soil Engineering aspect, be specifically related to a kind of equipment that the motion of soil profile water salt is measured.
Background technology:
The northern area of China alkaline land area is big, and it is the vital task of local agricultural development that improvement utilizes the alkaline land.Be unable to do without the experimental study to holard salt migration mechanism in the improvement in alkaline land utilizes, a testing equipment easy to use can improve the efficient of experiment work and the reliability of test findings.
The main means of studying holard salt migration mechanism traditionally are to utilize earth pillar or the migration of soil box simulated soil water salt, soil sampling is measured soil moisture and salinity in the test, perhaps bury soil moisture probe and salt sub-probe underground, show soil moisture and salinity migration process according to the probe data of each point in earth pillar tube wall or the perforate of soil box wall.The shortcoming of these methods workload that is to fetch earth is big, defines the position of observation station in earth pillar tube wall or the perforate of soil box wall, in addition, also needs more probe, and experimentation cost increases.
Summary of the invention:
The present invention seeks to develop a soil box that can make things convenient for, effectively, intuitively study holard salt motion process, measure the moisture movement rule and the water salt characteristics of motion simultaneously.
The purpose of this utility model is achieved through the following technical solutions:
A square soil box (1), its feature comprise soil box framework (2), left and right, back, the downside transparent body (3), leading flank net (4), the inboard dash plastic sheeting (5) of leading flank net, water salt proving installation (6).
Feature left and right, back, the downside transparent body (3) can be had an X-rayed the moisture movement of soil, and effect is to describe ground moistening peak curve on the transparent body; Front side net (4) has been characterised in that certain intensity and has been insulator that effect is to support the pressure of soil water salt proving installation (6) not to be caused magnetic interference and short circuit simultaneously; Its role is to block water flows out from front side net (4); Water salt proving installation (6) is characterised in that the moisture and the salinity of testing soil change simultaneously.
As Technological improvement plan, the inboard dash plastic sheeting of above-mentioned leading flank net (5) also can be rubber diaphragm.
Compared with prior art, the utility model is not only simple in structure, can describe ground moistening peak curve, can also monitor the salinity variation of arbitrfary point soil by water salt proving installation simultaneously, just can satisfy test job with a water salt proving installation.Only need after the end of test (EOT) to change the inboard dash plastic sheeting of leading flank net, just can do down battery of tests, be simple and easy to usefulness, save cost.
Description of drawings:
Fig. 1 is a soil profile water salt test soil box synoptic diagram.
1 is square soil box, and 2 is the soil box framework, and 3 is left and right, back, the downside transparent body, and 4 is the leading flank net, and 5 is the inboard dash plastic sheeting of leading flank net, and 6 is water salt proving installation.
Embodiment:
Embodiment 1:
With reference to Fig. 1, it is the structural representation of embodiment 1 of the present utility model, comprise a square soil box 1, described soil box framework 2 is an angle steel, a left side, right, after, the downside transparent body 3 poly (methyl methacrylate) plates, leading flank net 4 duroplasts nets, the inboard dash plastic sheeting 5 of leading flank net is an igelite, water salt proving installation 6 is the pin type time-domain reflectomer, fill in the soil box for examination soil, a described left side, right, after, the downside transparent body 3 poly (methyl methacrylate) plates are characterised in that the moisture movement that can have an X-rayed soil, and effect is to describe ground moistening peak curve on the transparent body; Net 4 duroplasts nets in front side have been characterised in that certain intensity and have been insulator that effect is to support the pressure of soil water salt proving installation 6 not to be caused magnetic interference and short circuit for the pin type time-domain reflectomer simultaneously; The inboard dash plastic sheeting of leading flank net 5 igelites its role is to block water and flow out from front side net 4 duroplasts nets; Water salt proving installation 6 pin type time-domain reflectomers are characterised in that the moisture and the salinity of testing soil change simultaneously.
Embodiment 2:
Compare with embodiment 1, the difference of present embodiment is described soil box framework 2 square steel frameworks.
Embodiment 3:
Compare with embodiment 1, the difference of present embodiment is that the inboard dash plastic sheeting of leading flank net (5) is rubber diaphragm.
Embodiment 4:
Compare with embodiment 2, the difference of present embodiment is that the inboard dash plastic sheeting of leading flank net (5) is rubber diaphragm.
