Description
Technical field
The utility model relates to a kind of test apparatus, a kind of gas pressure consolidation appearance of measuring the compression performance of soil block of more specifically saying so, dependent territory worker's test apparatus.
Background technology
The compression performance of soil under the condition that the gas pressure consolidation appearance is used to be determined at different loads and lateral confinement is arranged.Existing gas pressure consolidation appearance comprises framework, determining displacement appearance support, determining displacement appearance, and the test specimen tube in framework is provided with lower cover in the test specimen tube, and the below of test specimen tube is provided with jacking block, and the below of last jacking block is provided with the air pressure bag; Frame roof has crossbeam, and crossbeam is provided with the determining displacement piece, vertical fixing bar below the crossbeam, and the lower end of fixed bar withstands on the lower cover; Determining displacement appearance support and test specimen tube are fixed, and the determining displacement appearance is fixed on the determining displacement appearance support, and the measuring point of determining displacement appearance is on the determining displacement piece on the crossbeam.Above-mentioned gas pressure consolidation appearance is when measuring the compressibility of soil, and fixed bar withstands lower cover, and the air pressure bag is pressurizeed; Make soil block sample compression in the test specimen tube; Push on jacking block and the test specimen tube and move, make determining displacement appearance support and determining displacement appearance also take place to move, because the determining displacement piece invariant position on the crossbeam of support; The position of the measuring point of determining displacement appearance is also constant; Therefore the distance between the measuring point of determining displacement appearance and determining displacement appearance changes, and the reading of determining displacement appearance changes, thereby draws the compression performance of soil block according to the corresponding relation of the reading of the pressure of air pressure bag and determining displacement appearance.When above-mentioned gas pressure consolidation appearance analyzer is measured the compression performance of soil block, when being pressurizeed, the air pressure bag increases step by step, still; In practical operation, control relatively difficulty of less air pressure, when especially air pressure is less than 0.1MPa; Cause the instability of air pressure through regular meeting, result's accuracy is measured in influence.
The utility model content
To the problems referred to above, the problem that the utility model quasi-solution is determined provides the gas pressure consolidation appearance of the less pressure of the stable control of a kind of ability, to guarantee to measure result's accuracy.
For addressing the above problem; The utility model has adopted following technical scheme: a kind of gas pressure consolidation appearance, and it comprises framework, determining displacement appearance support, determining displacement appearance, the test specimen tube in said framework; Be provided with lower cover in the said test specimen tube, the below of said test specimen tube is provided with the air pressure bag; Said frame roof has crossbeam, and said crossbeam is provided with the determining displacement piece, vertical fixing fixed bar below the said crossbeam, and said stating has the fixed bar perforation on the crossbeam, and said fixed bar passes the fixed bar perforation; Said determining displacement appearance support and test specimen tube are fixed; Said determining displacement appearance is fixed on the determining displacement appearance support; The measuring point of said determining displacement appearance is on the determining displacement piece on the crossbeam, and the bottom of said fixed bar is counterweight fixedly, and the diameter of said counterweight is greater than the diameter of fixed bar perforation.
Said determining displacement appearance is dial gauge or displacement transducer.The quality of said counterweight is not more than 500 grams.
Owing to adopted said structure, the gas pressure consolidation appearance of the utility model is fixing counterweight in the bottom of fixed bar, when the gas pressure consolidation appearance is tested; Its preliminary pressure substitutes air pressure with counterweight, promptly pushes down lower cover through counterweight, makes the soil block sample in the lower cover compression test specimen tube; Lower cover moves down; Counterweight, fixed bar, move determination block, and at this moment test specimen tube, determining displacement appearance support, determining displacement appearance position change not, thereby the determining displacement appearance produces the reading that moves down also along with moving down.Behind the preliminary pressure of accomplishing the last stage; To air pressure bag pressurization, test specimen tube, determining displacement appearance support, determining displacement appearance, counterweight move simultaneously, on move on to counterweight and withstand the fixed bar punch position; The determining displacement appearance begins counting; Then along with the increasing of air pressure bag pressure, counterweight, fixed bar, move determination block not in the variation of occurrence positions, and along with the compression to the soil block sample in the test specimen tube; Test specimen tube, determining displacement appearance support, determining displacement appearance rise on the position, and the determining displacement appearance produces reading to be changed.Thereby the gas pressure consolidation appearance of the utility model has overcome controls relatively difficulty of less air pressure, causes the unsettled deficiency of air pressure easily, has improved the accuracy of measuring the result.
