Problems solved by technology

[0004] In the above technology, the function of the mold is single, and it is impossible to realize the function that the sample and the prefabricated crack pattern can be adjusted at the same time
In the laboratory test of rock mechanics, samples of different sizes and various cracks are often required, but the current molds can only prepare certain types of samples, which is not only labor-intensive and time-consuming, but also causes waste of resources

Abstract

The invention discloses an adjustable model for the preparation of a rock specimen containing cracks and a use method thereof. The form comprises a base, a size-adjustable model frame and an upper press plate; the upper press plate is a rectangular steel plate which can be taken away or positioned on the model frame like a lid; the center of the rectangular steel plate is provided with a round hole, the circumference of the round hole is provided with angle markings, a round positioning plate is located in the round hole, the round positioning plate is provided with clearance positioning grooves of different distances and angle indication marks. For the model frame size is adjustable, therefore suitable to the preparation of specimens of various sizes, thus overcomes the old day shortage of one model set for only one specimen size, and achieves the function of specimens preparation in many different sizes; because the round positioning plate can spin at will, therefore can adjust the angle of a prefabricated clearance. The clearance positioning groove on the round positioning plate can adjust the distance between the clearances, this fact blazes a trail in the shortcomings of monotone styles of prefabricated model clearances in the past and achieves the prefabrication of clearances with different angles and different distances.

Description

technical field [0001] The invention relates to the technical field of rock similarity model tests. Background technique [0002] In the field of rock mechanics, a large number of indoor rock mechanics experiments are required, including tests on standard samples and various samples with different cracks. However, it is difficult and costly to obtain rock samples on site, especially for most soft rock samples. It is not easy, and it is difficult to fully satisfy the detailed research on a certain aspect of rock mechanics by only relying on samples prepared from on-site rock samples. Therefore, at present, gypsum, sand, cement and other materials are often used to prepare rock-like materials to replace the original rock materials for related experimental research, and before carrying out related experiments, it is often necessary to prepare rock-like samples of various sizes with different cracks. [0003] According to the preparation requirements of different types of rock ...
