The invention discloses a surrounding rock strength testing device, system and method, relates to the technical field of surrounding rock in-situ dynamic testing, and is used for solving the problems of non-uniform manual testing acting force and difficulty in reading when an existing needle penetrometer is used for measuring the uniaxial compressive strength of soft rock. The rock mass strength testing device comprises a shell which is provided with a data interface, wherein the data interface is used for being in communication connection with an upper computer; a fixing device which is connected with the shell and is used for fixing the shell on a rock mass; a testing assembly which comprises a driving part, a transmission part and a testing part which are in transmission connection in sequence, wherein the driving part is electrically connected with the data interface, and the driving part is used for driving the transmission part to drive the testing part to be inserted into the rock mass when the testing signal is received from the data interface; and a detection device which is arranged in the shell and electrically connected with the data interface, wherein the detection device is used for detecting the displacement of the test piece inserted into the rock mass and the pressure borne by the test piece when the test piece is inserted into the rock mass.
Description
technical field [0001] The invention relates to the technical field of in-situ dynamic testing of surrounding rock, in particular to a surrounding rock strength testing device, system and testing method thereof. Background technique [0002] The research on the physical and mechanical properties of rock mass plays an important role in the stability analysis of surrounding rock, especially the compressive index of rock mass. Soft rock is a common rock mass. Soft rock has low strength, loose structure, and complete coring is difficult. Moreover, it is difficult to process soft rock into high-quality standard specimens to test the uniaxial compressive strength, which makes it difficult to measure the uniaxial compressive strength of soft rock on-site sampling and indoor standard tests, and it is impossible to objectively obtain the impact of on-site construction. mechanical parameters. Therefore, soft rock needs to be tested in situ on site. [0003] The needle penetrometer ...
