Description
Technical field
This utility model relates to a kind of ground or other materials test specimen batch under fixation pressure and carries out the device used by ultrasonic testing, the ultrasound data test being especially adapted for use under the setting pressure of soil body test specimen.
Background technology
The intensity level of Rock And Soil or other construction materials is himself important physical index, and the method testing soil strength in conventional research has a variety of, indoor predominantly triaxial machining, direct shearing test and single shaft non-confining compression strength test etc..This type of method test result accurately and reliably, but experiment itself belongs to destructive testing (test be required for destroying one or more test specimen) every time.If the intensity of test specimen different times to be tested (test piece intensity under such as different freezing-thawing cycles), then the quantity of required test specimen is a lot.Prepare substantial amounts of test specimen not only input to increase, and test required time and be also greatly increased.In order to make up this defect, the strength test of material introduces ultrasound wave Non-destructive Testing Technique, utilize the size of ultrasonic velocity to react the size of Rock And Soil intensity.The benefit of ultrasonic testing can carry out lossless detection exactly, and sample can be recycled, and thus substantially reduces experiment process and saves funds.But needing artificial hand-held ultrasound probe to test test specimen during ultrasonic testing, the variant meeting of strength applied during test causes ultrasound test result to produce fluctuation.In general, the velocity of wave of the biggest test specimen of pressure that both hands apply can be the biggest.When batch testing, test specimen can cause individual data items difference bigger because of different test specimen forces in ultrasonic testing, it is impossible to accurately reflects the Changing Pattern of intensity.Especially for soil body test specimen, applying pressure when between probe, to cross hour data inconspicuous, and pressure is crossed conference and caused test piece deformation to crush, so keep an appropriate force value necessary when soil body test specimen batch testing.
Summary of the invention
The purpose of this utility model is that the same batch test specimen stress when carrying out ultrasonic testing differs for rock soil test piece or other materials, the data inaccuracy caused, it is provided that a kind of adjustable rock soil test piece ultrasonic testing sample stage.
This utility model is by fixed dam, detachable backing plate, base, wave speed probe, sideboard, Rectangular Spring and guide rod are constituted, surrounding on base arranges fixed dam, it is formed with sample cell between the fixed dam of surrounding, two sideboards are positioned at sample cell, the inner side of two sideboards is equipped with wave speed probe, test specimen can be placed between wave speed probe, between sideboard and the fixed dam of end of one end, detachable backing plate is set, between sideboard and the fixed dam of the other end, Rectangular Spring is set, this sideboard is fixed with guide rod, guide rod passes sideboard.
Work process of the present utility model:
By making the test specimen of certain length and diameter according to the requirement of experiment with research with a batch of sample, being positioned in sample cell by test specimen, regulation sideboard, in suitable position, places a number of detachable backing plate, reading.Same batch test specimen is carried out by same steps successively, completes test.
The beneficial effects of the utility model:
Easy and simple to handle, overall volume is small and exquisite, can be prevented effectively from experimentation the data fluctuations caused due to force inequality.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model.
Fig. 2 is sectional view of the present utility model.
Detailed description of the invention
As depicted in figs. 1 and 2, this utility model is by fixed dam 1, detachable backing plate 2, base 3, wave speed probe 4, sideboard 6, Rectangular Spring 7 and guide rod 8 are constituted, surrounding on base 3 arranges fixed dam 1, it is formed with sample cell between the fixed dam 1 of surrounding, two sideboards 6 are positioned at sample cell, the inner side of two sideboards 6 is equipped with wave speed probe 4, test specimen 5 can be placed between wave speed probe 4, between sideboard 6 and the fixed dam 1 of end of one end, detachable backing plate 2 is set, between sideboard 6 and the fixed dam 1 of the other end, Rectangular Spring 7 is set, this sideboard 6 is fixed with guide rod 8, guide rod 8 is through sideboard 6.
This utility model using method is as follows: as depicted in figs. 1 and 2.
1. test sample is made the former cylinder of long 3-10cm, a diameter of 4-7cm, then the test specimen 5 prepared is put into sample cell.
2. hold up steady test specimen 5, the left hand slowly right side to push away at sideboard 6 to the ultrasonoscope data stabilization of left side with the right hand, write down the position of right side sideboard 6.
The most meanwhile another one experimenter places a number of detachable backing plate 2 to the left between fixed dam 1 and sideboard 6, and the detachable backing plate of last block 2 makes the right side sideboard 6 position just when ultrasound data is stablized just now after putting into.
4. after the ultrasound data after read test, left hand buttresses test specimen 5, and the right hand slightly firmly right side pushes away right side sideboard 6, and left hand takes out test specimen 5 simultaneously.
5. left hand takes the next test specimen 5 needing test, and testing stand keeps setting just now, and the right hand slightly firmly right side pushes away right side sideboard 6, and left hand puts into test specimen 5 to be tested, reading.This value is this group test specimen test value at the same pressure.
6. continuing the test of next test specimen, step is ibid.
Ultrasonic testing force value measuring method: the annulus of dynamometry guide rod 8 on the right side of ergometer is connected, when being pulled to test test specimen 5 on the right side of the position that is parked in of sideboard 6, force value during the now reading of ergometer i.e. test specimen test.
