Compression tester without disturbed soil

Abstract

The invention discloses a compressionmeter of nondisturbed soil. A crossbeam is installed on the upper of the upright post of the bottom plating, a load bearing knife edge on the upper head face of the longitudinal girder and the groove on the bottom head face of the crossbeam are matched and fixed, the balancing counter poise is placed on the short longitudinal girder, the outer frame component comprising the load disk and the hook is equipped on the bottom of the long longitudinal girder; the bottom permeable stone, the spacing ring and the cutting ring are equipped in the hole of the foundation; the inner tube is composed of three petals and is inserted into the outer tube, the inner tube is matched with the excircle of the cutting knife, one ends of three fixed poles are respectively hinged joint with foundation, the other ends are equipped with top caps and press on the head face, when the soil body is pressed into the inner tube, the permeable stone is pressed on the soil body from the top cap, the top pressure cap is pressed on the permeable stone to form a pressure cabin component. The pressure cabin component is installed on the outer frame rack component bottom plating, the crossbeam and longitudinal girder location are adjusted, the pressure column is covered into the top pressure cap, the longitudinal girder is aimed at the top pressure cap center by pressure column, which form the nondisturbed soil compressionmeter. In order to provide nondisturbed soil sample for related research, the remoulded soil can be molded and pressed therein, and forms a sample without disturbance.

Description

technical field [0001] The invention relates to a soil test device, in particular to a compression tester for undisturbed soil. Background technique [0002] In the study of soil strength, it can be seen that the strength of soil has a great relationship with the degree of disturbance it receives, and the strength of undisturbed soil samples is much greater than that of disturbed soil samples. Therefore, many researchers explored the correlation between the strength of the undisturbed soil sample and the disturbed soil sample in order to determine the degree of strength reduction of the disturbed soil sample. Moreover, the degree of disturbance to the soil sample is different, and the degree of strength reduction is also different. Then in the research, it is necessary to have suitable methods and instruments to simulate different degrees of disturbance, and to ensure that the simulated state can be reasonably maintained and its strength can be accurately tested. The compr...
