Description
Technical Field
The utility model relates to the technical field of rock sample preparation, in particular to a device for preparing a rock sample containing complex joints.
Background
The natural rock forms various joints under the action of tectonic stress, and the mechanical strength of the rock body is greatly reduced due to the joints. Joints are ubiquitous in rock masses, and therefore most of the works involving rock masses cannot take into account the effect of joints on the stability of the worked rock mass. With the advance of underground engineering, mining engineering and petroleum engineering, the scale of the related rock mass engineering is continuously enlarged, and the research requirements on mechanical properties and fracture of jointed rock mass are more urgent. In order to disclose the damage and fracture mechanism of the jointed rock mass and obtain mechanical parameters thereof so as to guide engineering design, students develop in-situ tests, similar model tests and indoor tests. In-situ tests and similar model tests can better restore the stratum joint distribution information, but the in-situ tests and the similar models are time-consuming and labor-consuming, and the obtained data have high discreteness and are inconvenient for large-scale research.
In view of the above, the students tried to reflect the joint information in the standard sample of the indoor test and to explore the damage and fracture mechanism of the joint rock mass through the indoor mechanical test. The prior scholars prefabricate joints in the test specimens mainly by means of similar material pouring. The pouring mode of similar materials is simple and easy to implement, and the homogeneity of the sample can be ensured. However, similar materials cannot completely reflect the brittleness of rock materials and the influence of mineral grains, so that the students can make joints in real rock samples by cutting and splitting, but the joints made by the method are simple in distribution and cannot reflect the fact that the joints contain fillers. Therefore, the utility model provides a manufacturing method aiming at the difficult problem that the cylindrical sample containing the complex filling joint is difficult to manufacture.
