Description
Technical field
The present invention relates to Soil Water Content Rate Determination device and method, and in particular to a kind of dress of quick measure soil moisture content
Put and method.
Background technology
In soil test, general indoor measurement of water-content coefficient method is oven drying method, the method that field quickly determines moisture content
There are alcohol combustion method and hydrometer method.Oven drying method can determine the moisture content of clayey soil, sandy soil, although this method is accurate, but determine
Great soil group scope it is big, but be a commonly-available water ratio test result and at least need 6 hours, and baking oven need to be used, so in engineering
Scene can not realize the quick measure of moisture content.Although alcohol combustion method and hydrometer method can quickly determine moisture content, wine
The result of the test of smart combustion method is relevant with test operation and experimental phenomena judgement, larger fluctuation as a result be present；And hydrometer method is only
The moisture content of sand class can be determined, and existing assay method typically will calculate moisture content, people by manual record weight loss
Time-consuming for work processing data.
The content of the invention
Goal of the invention：It is an object of the invention to provide a kind of rapid determination device of soil moisture content and method, solves existing
There is measure soil moisture content the problem of time-consuming, and data result error is big.
Technical scheme：The rapid determination device of soil moisture content of the present invention, including warm table, weighing system sum
According to processing system, sample standing groove is provided with the warm table, the sample standing groove is interior covered with heating plate, described to weigh
System is arranged in the warm table below sample standing groove, and the data handling system is connected with weighing system signal to draw reality
When moisture content data.
In order to displaying data in real-time, the data handling system includes data processor and display screen, at the data
Reason device electrically connects with display screen, the real-time moisture content data of display screen display data processor processing.
Fetch earth for convenience, improve soil by thermal velocity, in addition to soil sampler, it be adapted to heating tank, and if inside by
Dry separation trough composition, soil sampler are made up of casting aluminium material.
The method of the rapid determination device measure soil moisture content of soil moisture content of the present invention, it is characterised in that
Comprise the following steps：
(1) standard aqueous rate soil sample is prepared；
(2) weighed after soil sampler is numbered by weighing system, the data weighed are recorded by data handling system
Display；
(3) soil pattern to be measured and standard aqueous rate soil sample are taken with the soil sampler after numbering, is then placed individually into heating
In groove, set temperature of heating plate to heat soil pattern, until weighing system is shown as stopping heating during constant weight, and pass through
Data handling system carries out moisture content calculating, and result of calculation is shown.
Beneficial effect：Weighing data processing automation of the present invention, time-consuming short, measurement result is accurate.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of soil sampler.
Embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, the rapid determination device of soil moisture content, including warm table 3, weighing system 4, data processing system
System 5 and soil sampler 6, is provided with sample standing groove 1 on warm table 3, is covered with heating plate 2, heating plate 2 in sample standing groove 1
Cast aluminium material, weighing system 5 are arranged in the warm table 3 of the lower section of sample standing groove 1, and data handling system 5 is believed with weighing system 4
To draw real-time moisture content data, data handling system 5 includes data processor and display screen for number connection, data processor and
Display screen electrically connects, the real-time moisture content data of display screen display data processor processing, and soil sampler 6 is suitable with sample standing groove 1
Match somebody with somebody, inside is made up of some separation troughs 7, and the quantity of separation trough 7 is set according to the amount of actual test soil, and soil sampler is also casting
Aluminium material is made, the soil sampler fetch earth it is simple and quick, be advantageous to field original place heating, without taking safeguard measure to be sent to experiment
Room, the soil of taking-up is in flake, it is easier to heats evaporating water.
Soil moisture content is determined using said apparatus, first with standard aqueous rate soil sample, record standard moisture content data；So
Weighed after soil sampler is numbered afterwards by weighing system, the data weighed are recorded by data handling system and shown, finally
Soil pattern to be measured and standard aqueous rate soil sample are taken with the soil sampler after numbering, is then placed individually into heating tank, sets and adds
200~300 DEG C of hot plate temperature heats to soil pattern, until weighing system is shown as stopping heating during constant weight, passes through number
Moisture content is drawn according to processing system, and result of calculation is shown, according to the measurement result calculation error of standard aqueous rate soil sample.
In order to contrast the test result of existing oven drying method and the present invention, four various criterion moisture content soil are prepared first
Sample, standard aqueous rate are respectively 28.98%, 38.11%, 42.59% and 43.97%；By oven drying method, using 108 DEG C of baking oven
Each standard aqueous rate soil sample is determined twice, measurement result is averaged, again by the present invention device and
Method is determined twice to each standard aqueous rate soil sample, measurement result is averaged, result of the test shows, oven drying method
Minute be 8 hours, use the present invention device and invention minute for half an hour, error is within 3%, accurately
Degree is high.Test data result is as shown in table 1.
The comparative test result of the oven drying method of table 1 and present invention measure moisture content
