Cutting device for preparing rock samples containing different dip angle structural surfaces and operation method

Abstract

The invention discloses a cutting device for preparing rock samples containing different dip angle structural surfaces and an operation method, relates to the technical field of rock mechanics tests, and comprises a base device, a sample fixing device, a combined bracket and the cutting device. A sample fixing mode is perfect, can realize fixation of the rock samples by various dip angles, guarantees symmetric stress of the samples in the cutting process, and prevents deviation and fracture of the cutting samples and unevenness of cut surfaces; rubber layers cover the surfaces of a fixed baffle plate and an auxiliary baffle plate, so that the rock samples are guaranteed to be not damaged in the clamping and fastening process; length marks, depth marks and angle marks are arranged for precisely controlling fixing angles, fixing positions and cutting depths of the samples; the cutting device uses a diamond saw blade with excellent rigidity and small thickness, so that the damage of the rock samples can be reduced in the cutting process, the integrity of the rock samples is guaranteed, and the service life is longer; and the cutting device is simple in structure, safe and convenient for operation, low in cutting cost and maintenance cost, small in size, light in weight and convenient for carrying.

Description

technical field [0001] The invention relates to the technical field of rock mechanics tests, in particular to a cutting device and an operation method for preparing rock samples with structural planes with different inclination angles. Background technique [0002] Rock mass is a natural object that exists in a certain geological environment, is cut by different structural planes, and has certain engineering geological characteristics. After undergoing geological tectonic movements of different periods and scales, geological interfaces of different origins and characteristics are formed inside the rock mass, such as faults, joints, layers, and fissures, which are collectively called structural planes. Structural planes are ubiquitous in rock mass engineering areas and directly affect the stability of rock mass engineering. [0003] With the rapid development of ground and underground rock mass engineering, more and more energy, transportation, mining, water conservancy and ...

AI Technical Summary

Problems solved by technology

[0021] The technical problem to be solved by the present invention is to provide a cutting device and an operation method for preparing rock samples containing structural planes with different inclination angles, so as to overcome the difficulties in making rock samples containing structural planes such as cracks and joints with different inclination angles in the prior art. During the preparation process, the cutting angle is difficult to control accurately, and the sample fixing method is not perfect, which easily leads to rock sample damage, uneven cutting surface, and inaccurate cutting parameters; with the increase of the cutting depth of the rock sample, the cutting blade and the rock The length of the cutting arc between the samples will continue to increase, resulting in increased friction between the cutting blade and the rock sample, increased motor load, high temperature, difficulty in chip removal, and blade loss
