Problems solved by technology

However, the sample loading work before the test and the sample unloading work after the test are very cumbersome and complicated, especially the sample unloading work after the test
After the test, it is necessary to take out the damaged sample after the test and take pictures and save it. After the sample is damaged, there will be a large volume of expansion. The large deformation makes it stuck in the rubber sleeve and cannot be taken out, or the expensive rubber sleeve is damaged when it is taken out, and it takes a lot of energy and a long time

Abstract

The invention provides a rock-like sample discharging device for a conventional triaxial test and a use method, and belongs to the field of geotechnical engineering tests. The rock-like sample discharging device comprises a vertical frame, a pressing column, a protection barrel, a base plate and fixers, wherein the vertical frame comprises a steel ring, a fixed frame and a supporting rod; the vertical frame is inserted into an insertion slot of the base plate; the pressing column is a steel column with a hard rubber pressing pad at the front end; the protection barrel is a rubber protection barrel with a closed bottom end; the base plate is a steel plate with the insertion slot; the fixers are plugged into screw holes of the fixed frame. Furthermore, the invention further provides the use method of the device. The device disclosed by the invention is simple in structure and convenient to use; the device can effectively protect the extraction intactness of a broken test sample.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering experiments, and relates to a sample unloading device and a use method for a rock-like conventional triaxial test. Background technique [0002] The indoor routine triaxial test of rock-like samples is a very important and routine experiment in the field of geotechnical engineering experiments. At present, a relatively complete indoor conventional triaxial test system for rock-like samples has been established at home and abroad, and there are relatively complete and reasonable specifications in terms of sample size, test type, and loading method. However, the sample loading work before the test and the sample unloading work after the test are all very cumbersome and complicated, especially the sample unloading work after the test. After the test, it is necessary to take out the damaged sample after the test and take pictures and save it. After the sample is damaged, there will be a large ...
