Description
Technical field
The present invention relates to a kind of soil test device, the measure of more particularly to a kind of soil moisture content of different depth is filled
Put.
Background technology
Moisture content is one of basic physical index of three-phase of soil, and influences fairly obvious to ground volume property, its numerical value
It is quick to determine that pair determination ground physico-mechanical properties has very important meaning.
Using the preceding measure for generally carrying out moisture content, its mode is the soil sample and container that will be weighed to soil in construction material
It is put into 105 ± 5 DEG C of baking oven and dries to constant weight, soil sample and container after drying are then weighed again, after record data, passes through
Formula calculates the moisture content of soil sample.Do in this way and determine twice, finally using the average value of measurement result twice as soil sample
The measured value of moisture content.This method time and effort consuming, completes once measure and generally requires or so 8 hours.The measure of fried dry method
Step is roughly the same with the above method, and soil sample is constantly turned with scuppit on operation format.This method can determine when
Between foreshorten to 30 minutes or so, but still do not break away from the use of drying plant, while there is also the defect for consuming the energy.
Additionally, the method for determining moisture content has alcohol combustion method, hydrometer method and real volumetric method, but all exist cumbersome.
The Chinese patent of Publication No. 205538541U discloses a kind of portable Water Content Tests in Soil Samples analyzer.The equipment bag
Casing is included, weighing apparatus and baker are separately installed with casing, quality readings display is provided with weighing apparatus, set on weighing apparatus
Box one is equipped with, box two is provided with baker;Also include a bull stick, bull stick one end is connected with box one, turn
The bar other end is connected with box two.The utility model is easy to carry, integrated simple operation, precision are higher;To weigh, show
Show, it is drying integrated, subtract human error simultaneously improve efficiency convenient use.
The Chinese patent of Publication No. 103592248A discloses a kind of colorimetric estimation method of soil moisture content, with 0.1
The organic solution of~30g/L CoCL2 6H2Os is that developer extracts pedotheque to be measured, removes solid matter, obtains solution to be measured,
Under the wavelength of 380~680nm, the absorbance of above-mentioned solution to be measured is determined;According to upper step gained absorbance in the suction set up
Corresponding soil moisture content is searched on luminosity-soil moisture content standard curve;Or be updated to upper step gained absorbance built
Vertical absorbance-soil moisture content calibration curve equation, tries to achieve corresponding soil moisture content.Survey moisture method of the invention is not received
The influence of soil type, composition, unit weight, disturbance etc., error can be controlled in less than 2%, is a kind of universality soil moisture content detection
Method;It is not only suitable for scene speed in the wild to survey, is also applied for laboratory and quickly determines soil sample moisture.
Although the Chinese patent of Publication No. 205538541U be convenient for carrying, integrated simple operation, precision are higher;To claim
It is weight, display, drying integrated, reduce human error and improve efficiency convenient use simultaneously, but energy resource consumption is still present, and deposit
In potential safety hazard.Though the Chinese patent of Publication No. 103592248A is not influenceed by soil type, composition, unit weight, disturbance etc.,
Error can be controlled in less than 2%, is a kind of universality soil moisture content detection method;It is not only suitable for scene speed in the wild to survey, also fits
Soil sample moisture is quickly determined for laboratory and accuracy of detection is high, can determine the soil sample of low-water-content, but it needs the later stage
Carry out the reading of soil sample absorbance, in addition it is also necessary to formula replacement below, be likely to result in unnecessary error.

Specific embodiment
With reference to specific accompanying drawing 1-2 and embodiment, to the present invention, the present invention is described further, but of the invention
Protection domain is not limited to that.
The present invention is a kind of portable soil tester for water ratio, including clear hollow body 1, transparent mobile pipe sleeve 2 and
The hollow piston rod 4 and conic-insertion-piece 3 of transparent mobile pipe sleeve close fit, described conic-insertion-piece 3 and the lower end of hollow body 1
It is fixedly connected into water-stop, described mobile pipe sleeve 2 is releasably fixed on a side of the hollow body 1 away from conic-insertion-piece 3, institute
The end handicapping of the hollow piston rod stated stops the limitation ring that described hollow piston rod is moved to conic-insertion-piece direction, the movement
Pipe sleeve wall is provided with vertical scale, and one end that described hollow body 1 is connected with conic-insertion-piece 3 offers sample port 5, described
Mobile pipe sleeve 2 bottom exceed the lowest part of sample port 5, end of the hollow piston rod near one end of conic-insertion-piece
Face is located at the top of the described highest point of sample port 5;Described conic-insertion-piece upper end offers water absorption reaction developing agent storage groove
6, bottom is tapered, and described water absorption reaction developing agent storage groove upper port is closely connected with described hollow body into water-stop;Institute
Water absorption reaction agent is stated for calcium carbide;The clear hollow body 1, transparent mobile pipe sleeve 2 are transparent organic glass;Described suction
Water reaction agent storagetank upper port is provided with the block 7 of fixed mobile pipe sleeve;The hollow piston rod 4 is made from light material.
Concrete operations of the present invention are:
(1) added in water absorption reaction developing agent storage groove 6 enough water absorption reaction agent (its Main Ingredients and Appearance be levigate calcium carbide and
Flyash dispersant is constituted) and fill and lead up whole, then conic-insertion-piece 3 is threadedly coupled fixation with hollow body 1, mobile pipe sleeve 2 is consolidated
It is scheduled in hollow body 1, mobile pipe sleeve coordinates with block 7 and touches water absorption reaction agent upper surface just.
(2) analyzer is depressed into designated depth stratum, mobile pipe sleeve is driven laterally using the ball of the mobile upper end of pipe sleeve 2
Pull, enough or slightly excessive pedotheques is entered inside mobile pipe sleeve 2 from sample port 5.
(3) treat that pedotheque is full of mobile pipe sleeve 2 and the chamber of the composition of hollow piston rod 4, mobile pipe sleeve 2 is pressed down at once
Until coordinate touching water absorption reaction agent upper surface just with block 7, mobile pipe sleeve is closed, now hollow piston rod 4 is subject to soil
The extruding of earth produces a small upward displacement, the mobile vertical scale reading of pipe sleeve is read at once and is designated as X1, treat water absorbing agent
The water absorbed in soil to be measured fully reacts, and because soil moisture is less, reaction will not be violent as in the pure water, can be quick
Producing acetylene gas, gas causes the generation of volumetric expansion hollow piston rod 4 to shift up, carries out reading and be designated as X2, calculate position
Move Δ X=X2-X1, then according to PV/T=C (constant), air pressure numerical value is calculated, gas is then determined by known equation of gaseous state again
Body pressure converses the numerical value of moisture content by equation of gaseous state formula, and then determine moisture content with the relation between moisture content.To carry
High measurement accuracy, can be repeated several times experiment, average.
Further, conic-insertion-piece of the present invention 3 is inhaled with hollow body to be removably threadedly coupled when needing to change
During water reaction agent, removable inferior pyramidal plug-in unit 3 is changed, very convenient.
The above implementation is only to absolutely prove the preferably implementation that patent of the present invention is lifted, the protection of this patent
Scope not limited to this.Equivalent substitute or conversion that those skilled in the art are made on the basis of this patent, at this
Within the protection domain of patent.The protection domain of this patent is defined by claims.
