Product Description
C142 Rock triaxial compression testing machine
The method of determining the strength and deformation of the specimen under triaxial axial pressure in the triaxial compressive strength test of rock. Calculate the strength and deformation parameters of the specimen under triaxial compression. It can also determine the compressive shear strength and Poisson's ratio of rock. Normally, a triaxial compressive strength test with unconsolidated drainage under lateral pressure and without measuring pore water pressure is used.
Experimental process: First, put the prepared rock test piece on the oil-proof latex sleeve and place it in the triaxial pressure chamber, center the rock sample pressure block and the ball seat, and then place the triaxial pressure chamber on the pressure testing machine. The pressure chamber is aligned with the pressure plate. Start-up, synchronously apply lateral pressure (confining pressure) and axial pressure to the preset lateral pressure value at a loading rate of 0.05mm/min, and keep the side wall pressure unchanged, and then at a loading rate of 0.5MPa~6MPa per second Load the axial pressure until the specimen is broken, and record the axial load and deformation values during the test.
