Description
Technical field
The utility model is related to a kind of soil test device, more particularly to a kind of measure of the soil moisture content of different depth
Device.
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 a pair determination ground physico-mechanical properties has very important meaning.
Soil in construction material is using the preceding measure for generally carrying out moisture content, and its mode is by the soil sample and container of weighing
Dried in the baking oven for being put into 105 ± 5 DEG C to constant weight, then weigh after soil sample and container after drying, record data, pass through again
Formula calculates the moisture content of soil sample.Do and determine twice in this way, finally the average value using measurement result twice is used 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.When this method can be determining
Between foreshorten to 30 minutes or so, but the use of drying plant is not still broken away from, while there is also the defect of the consumption energy.
In addition, the method for determining moisture content has alcohol combustion method, hydrometer method and real volumetric method, but all exist cumbersome.
Publication No. 205538541U Chinese patent discloses a kind of portable Water Content Tests in Soil Samples analyzer.The equipment bag
Include to be separately installed with casing, casing on weighing apparatus and baker, weighing apparatus and be provided with quality readings display, set on weighing apparatus
It is equipped with box one, baker and is provided with box two;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;It will weigh, show
Show, it is drying integrated, subtract human error and meanwhile improve efficiency convenient use.
Publication No. 103592248A Chinese patent 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 380~680nm wavelength, the absorbance of above-mentioned solution to be measured is determined;Absorbance is in the suction set up according to obtained by upper step
Corresponding soil moisture content is searched on luminosity-soil moisture content standard curve;Or be updated to absorbance obtained by upper step built
Vertical absorbance-soil moisture content calibration curve equation, tries to achieve corresponding soil moisture content.Survey moisture method of the present utility model
Do not influenceed by soil type, composition, unit weight, disturbance etc., error can be controlled in less than 2%, be 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 Publication No. 205538541U Chinese patent be convenient for carrying, integrated simple operation, precision are higher;It will claim
It is weight, display, drying integrated, reduce human error and improve efficiency convenient use simultaneously, but there are still energy resource consumption, and deposit
In potential safety hazard.Though Publication No. 103592248A Chinese patent 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.
