Description
Technical field
The utility model is related to roadbed Site Detection field, specifically the test dress of field quick detection soil matrix moisture content
Put.
Background technology
Roadbed is the important component part of highway, is the basis on road surface, with the effect that road surface shared traffic loading.
The quality of roadbed quality directly affects the use quality of the stability on road surface and entire road.The moisture content of Roadbed Soil is road
One of important indicator of base Construction control.During equal execution conditions, the subgrade soils of preferable moisture content are easier to stabilization by compaction, compacting
Roadbed afterwards has higher strength and stability.During operation, the change of external environment also causes at roadbed soil's water content
In constantly change.The change of roadbed moisture content will affect the physico-mechanical properties of roadbed, the particularly intensity of roadbed, rigidity
And stability, and the subgrade resilient modulus as roadbed design index change also with the mechanical periodicity of moisture content.Therefore roadbed
Moisture content is not only the key factor of Construction control, and is also the key factor for affecting road structure performance.
Now have various for the assay method of roadbed moisture content, such as oven drying method, alcohol combustion method, fried dry method, calcium carbide
Subtraction method and nucleon ray method etc., the method for clear stipulaties is oven drying method, alcohol combustion method in specification.But existing detection method
In more or less there is certain defect, though such as oven drying method test is easy, as a result stable, high precision, the method is needed indoors
Carry out, such as field sampling has scattering and disappearing for moisture, is not suitable for the detection at scene；Alcohol combustion method is applied to without baking oven and electricity
In the case of source device, it is generally used for scene or determines the air-dried moisture content of sample for sample preparation reference, but alcohol is dangerous material, there is one
Fixed potential safety hazard, and the quality of alcohol affects test result.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of measuring accuracy height, result good stability, detection process
Fast, easily the experimental rig of field quick detection soil matrix moisture content, can overcome the deficiencies in the prior art.
To solve the above problems, the utility model is adopted the following technical scheme that：The examination of field quick detection soil matrix moisture content
Experiment device, it includes chamber, cabinet door is provided with chamber, and battery is provided with chamber, and electricity is provided with chamber
Magnetic electro-heat equipment, meausring apparatus and air interchanger, battery is powered to electromagnetic heating device and air interchanger.
The experimental rig of above-mentioned field quick detection soil matrix moisture content is that the top in chamber is provided with air stirring
Device.
The experimental rig of aforesaid field quick detection soil matrix moisture content is, described electromagnetic heating device by magnetron,
High-voltage rectifier and transformer combination are constituted.
The experimental rig of aforesaid field quick detection soil matrix moisture content is, in chamber（1）Lower section be provided with and can adjust
The pedestal of height, is provided with levelling tube on pedestal.
Compared with the prior art, the utility model arranges battery in the chamber for be provided with window, sets in chamber
There are electromagnetic heating device, meausring apparatus and air interchanger, battery is powered to electromagnetic heating device and air interchanger, thus may be used
Electromagnetic heating device work is driven by battery so that this device can be used for open air, because of the equal position of heating check weighing of package unit
In chamber, convenient, accuracy of detection is higher for its relatively existing alcolhol burner heating, drying, result stability more
Good, detection process is faster.Air interchanger regular working is so as to the more preferable moisture discharged in chamber；It is provided with chamber
Agitator, can so make the temperature in chamber more uniform.Being provided with below chamber can adjust the pedestal of height, this
Sample is by adjusting the rotatably supported height on pedestal, and then leveling levelling tube so as to which interior bubble is placed in the middle, to ensure equipment
Level, increases measuring accuracy.The magnetron, high-voltage rectifier, transformer primarily serve the purpose of generation heating microwave, for heating
Soil sample makes the moisture evaporation in it.Mode of heating may be configured as laser heating formula and interruption heated type, thus can be according to being surveyed
Thing humidity is controlled.The precision of the electronic weighing system is the meausring apparatus of 0.01g, and it is well positioned to meet measuring accuracy
Requirement.
