Problems solved by technology

For soft clay samples, during the process of installing the cap, top cover and sealing inner membrane, additional axial stress may be generated on the sample due to the weight of the top cover of the sample and the deviation of manual operation, which will affect the soil properties. greater impact

Abstract

The invention discloses a topping localizer of status quo hollowness column sample. It includes the right bit block place machine and left bit block place machine on the top of the localizer,the block place machine fixed screw,the block place machine fixed screw pole,the block place machine fold screw pole,right bit block place machine and left bit block place machine on the bottom of the localizer,the localizer temper screw,the localizer temper screw location screw cap and sample pedestal location notch, the right bit block place machine and left bit block place machine on the top of the localizer connect with the localizer fixed screw to form the top localizer block place machine, the right bit block place machine and left bit block place machine on the bottom of the localizer to form the bottom localizer block place machine, the top localizer and the bottom localizer block place machine connect with the block place machine fixed screw pole by the four localizer temper screws. The invention avoids bringing the disturb when fix the coping,capping sheet and center form of status quo soft clay hollowness column sample, ensuring the dependability and authenticity of the data of experiment.

Description

technical field [0001] The invention relates to a positioner for the top cover of an original hollow cylindrical sample. Background technique [0002] At present, there are few experimental studies on the original hollow cylindrical soft clay samples at home and abroad, and there is no mature technology for the installation method of the samples. Usually, the top of the hollow sample needs to be installed with a top cover and a cap to realize the sealing of the inner membrane of the sample and the connection between the sample and the test device. For soft clay samples, during the process of installing the cap, top cover and sealing inner membrane, additional axial stress may be generated on the sample due to the weight of the top cover of the sample and the deviation of manual operation, which will affect the soil properties. greater impact. In order to reduce the disturbance of the sample by the additional axial force, a positioner for the top cover of the original hollo...
