1. research shows that in the process of measuring the sound wave velocity of the rock sample by manually pressing the test probe, because the force for manually pressing the test probe is unstable, the contact pressure between the test probe and the rock sample is easy to be unstable, the coupling contact tightness between the test probe and the rock sample is inconsistent, and the sound wave velocity test data of the rock sample is inaccurate.
In order to improve the stability of the contact pressure of the test probe and the rock sample, the constant-pressure rock sample sound wave velocity test device is designed, and in the test, the sound wave velocity test can be carried out by applying stable pressure to the rock sample through the constant-pressure rock sample sound wave velocity test device.
2.
