Description
Technical Field
The utility model relates to the technical field of rock test piece measurement, in particular to a rock test piece basic physical parameter measurement device.
Background
Before the indoor rock mechanics experiment test, the collected rock mass sample needs to be processed into a standard test piece with a certain size, and then the test of the relevant strength can be carried out on a press machine. According to the related requirements of the rock physical and mechanical property test procedure (DZ/T0276-2015) and the International Society of Rock Mechanics (ISRM), taking a rock uniaxial compressive strength test as an example, a required test piece should be processed into a standard cylinder, the diameter is 50mm (the allowable variation range is 49-51 mm), and the height is 100mm (the allowable variation range is 99-101 mm).
However, due to the influence of many factors such as the processing test piece equipment and personnel level, the processed test piece cannot be completely standard, so that the measurement is generally required to be carried out for 3 times to obtain an average value in the measurement process. In the case of dimensional measurement, it is required to measure and record the height and diameter of a test piece using a vernier caliper with high accuracy, and the result is accurate to two decimal places. Taking a circular test piece as an example, measuring the diameters of the upper end, the middle end and the lower end and the heights of three different angles respectively by using a vernier caliper, and taking an average value for recording for later use. In the mass measurement, the mass is also required to be weighed three times by a high-precision electronic analytical balance to be averaged for standby. And finally, calculating the density of the test piece according to the mass and size data. Therefore, before indoor rock mechanics, a test piece needs 6 dimensional measurements and 3 mass measurements, so that the measurement of basic physical parameters of the rock test piece is complicated, and the error of a test result is too large due to the fact that the vernier caliper is not parallel enough when clamping the test piece during the measurement of the dimension.
