Problems solved by technology

With the rapid development of modern rock mechanics theory, experimental instruments for testing various rock mechanical parameters have emerged as the times require. Although there are many types of existing rock mechanics test instruments, they can basically meet the test requirements of various rock mechanics parameters, but related Among the rock mechanics test equipment and methods, there is no instrument for depicting the cracks of the rock samples after failure. The common method is to use a digital camera to take pictures of the damaged rock samples at different angles and then manually describe and record the failure cracks of the rock samples. There are difficulties in the positioning and splicing of rock samples, which often lead to inaccurate description of cracks on the surface of rock samples, the subjective influence of operators is relatively large, and the operation process is more troublesome

Embodiment Construction

[0030] Such as figure 1 , figure 2 Among them, a rock sample crack drawing device includes a tracer and a support platform 2. The tracer includes a transparent container 1 with longitudinal and abscissa coordinates. The support platform 2 is connected with the transparent container 1 through a bearing, and the transparent container 1 can be relatively The support platform 2 rotates, and the transparent container 1 is a hollow cylinder or a hollow square with different sizes and specifications. The transparent container 1 is made of a resin material with high transparency and good wear resistance.

[0031] The preferred rock sample crack drawing device, the tracer also includes an electronic sensing point and a signal recorder located on the coordinates of the transparent container, the electronic sensing point is electrically connected with the signal recorder, and the tracing pen touches the electronic sensing point on the transparent container, The coordinate data correspo...

Abstract

The invention provides a device and a method for tracing cracks of a rock sample. The device comprises a tracer and a support platform, wherein the tracer comprises a transparent container with the Y-coordinate and the X-coordinate, the support platform is connected with the transparent container by bearings, and the transparent container can rotate relative to the support platform. The method comprises the following steps of installing the rock sample, tracing points, and imaging; or installing the rock sample, scanning and carrying out image processing. The device for tracing the cracks of the rock sample has the advantages of simpleness in manufacturing, high precision, convenience in operation and maintenance, and realization in programmed tracing; the method for tracing the cracks of the rock sample has the advantages of high working efficiency and convenience.

Description

technical field [0001] The invention relates to the field of rock mechanics tests in civil engineering, in particular to the crack drawing and digital transformation of rock samples after they are destroyed. Background technique [0002] Rock mechanics test is the basis of rock mechanics and one of the important means to study rock mechanics and engineering. Although scientific calculation and theoretical analysis have reached a considerable height, rock mechanics tests still play an irreplaceable role in directly solving mechanical problems in practical engineering. With the rapid development of modern rock mechanics theory, experimental instruments for testing various rock mechanical parameters have emerged as the times require. Although there are many types of existing rock mechanics test instruments, they can basically meet the test requirements of various rock mechanics parameters, but related Among the rock mechanics test equipment and methods, there is no instrument ...
