[0037] The present invention will be further described below in conjunction with the drawings.
[0038] Such as Figure 1-Figure 3 As shown, an information acquisition device based on real-time rock destruction of the present invention includes an acoustic emission detector, a CT scanner, a loading press 101 and a displacement sensor 117. The loading press 101 pressurizes the test piece in the sleeve 102 Displacement sensor 117 measures the axial displacement of the specimen during pressurization; the acoustic emission detector receives and collects the acoustic signal from the destruction of the specimen, and after processing the acoustic emission signal, the acoustic emission host 201 records and analyzes it; CT scan The instrument observes the internal damage of the test piece in real time; the sleeve 102 includes a sleeve 109, an upper spherical seat 121 and a lower spherical seat 112. Both ends of the sleeve 109 are threadedly connected to the upper spherical seat 121 and th...
