Problems solved by technology
However, the measurement principle of this kind of instrument is relatively complicated, which leads to relatively large and bulky volume, and it is difficult to carry out in-situ test. The carrying and on-site use of the instrument have become a big problem. Therefore, almost all indoor tests are unavoidable, but the rock is not in situ. The change of the mechanical properties of the experiment leads to a large difference between the results of the indoor test and the in-situ test. This is a fatal flaw in the indoor rock mechanics experiment, and it cannot achieve the effect of real-time monitoring and mapping and the determination of the same strain under different solution concentrations under the same stress. It takes time to achieve the effect of equivalent replacement
In summary, the current instruments cannot meet the requirements of measuring the axial and radial displacement of rocks under in-situ simulated erosion conditions, and timely mapping and equivalent replacement to study rock strain properties

The invention provides a portable in-situ erosion rate measuring instrument for rock. The measuring instrument comprises a rigid bearing plate; a sampling hole is arranged in the central part of the rigid bearing plate; a toughened glass container is arranged on the sampling hole; one end of a pressure block is inserted into the toughened glass container while the other end of the pressure block is connected with a lifting device; the sampling hole and the pressure block are separately provided with a displacement meter probe; a displacement meter receiver is arranged on the upper end of the pressure block and used for receiving signals of the displacement meter probes; and a water quality testing meter penetrates the wall of the toughened glass container and is then communicated with the sampling hole. The invention has the following advantages: a method for in-situ measurement of axial displacement and radial displacement of rock under axial strain is provided for researching the erosion rate of rock under stress; and by adopting the instrument provided by the invention, testing time is effectively shortened.
Description
technical field [0001] The invention designs a measuring instrument, in particular to a portable rock in-situ erosion rate measuring instrument. Background technique [0002] In the prior art, there are many devices for measuring the deformation of rocks under stress (such as "A Rock Deformation Detection Device"), and there are also devices for measuring the deformation of rocks under stress in chemical solutions (such as "Rock Fracture under Chemical Corrosion") Process triaxial compression mesomechanics test device"). However, the measurement principle of this kind of instrument is relatively complicated, which leads to relatively large and bulky volume, and it is difficult to carry out in-situ test. The carrying and on-site use of the instrument have become a big problem. Therefore, almost all indoor tests are unavoidable, but the rock is not in situ. The change of the mechanical properties of the experiment leads to a large difference between the results of the indoor ...
