A Preparation Device for Compressive Pre-stress Artificial Core
Technical Field The invention relates to the field of artificial core preparation technology, in particular to a preparation device for compressive pre-stress artificial core.
Technical Background Rock material is a kind of non-uniform medium. The microscopic particles that make up the rock have differences in terms of mechanical properties and thermal conductivity. Under the effect of pressure and temperature changes, local plastic deformation will occur, causing part of the stress to be stored in it. In the process of rock mechanics and engineering, mining engineering and excavation engineering, it is often found that, for example, the release of rock burst strain energy, the deformation caused by stress relaxation of soft rock roadway, the abnormal uplift at the excavation bottom of foundation pit, and the rock loosening during the creep of landslide as well as other phenomena, these phenomena are related to the accumulation and release of internal stress in rock. Therefore, the study of the generation and release of internal stress in rock must be given sufficient attention. It is an important method and approach to study the engineering properties of rock internal stress by studying the accumulation and release law of rock internal stress through laboratory tests. Due to the uncertainty of the internal stress in the natural rock, and the test of the test sample is destructive, it is impossible to repeat the test once the sample is damaged; due to the high cost and great uncertainty of natural internal stress rock sampling, it is impossible to obtain suitable samples, therefore, it is necessary to artificially prepare internal stress samples for experimental study. However, currently, there are few related experimental studies on the internal stress of rock, especially the related technologies and equipment for simulating the internal stress of rock have not been discovered.
The Chinese invention patent with application No. 201210101103.8 discloses an artificial long core and its preparation method. This method is to solve the problem that the length and size of the existing artificial core are difficult to meet the experimental requirements, and the external force in the core preparation process does not explain the storage of the core stress; the Chinese invention patent with application No. 201410260860.9 discloses a preparation method for joint shale artificial core. This method is to solve the problem that the existing artificial core does not have joints, and does not elaborate the related technology and description of stress storage in the core preparation process. The Chinese invention patent with application No. 201510329020.8 discloses a sample preparation mold for rock mechanics tests. This method is to solve the problem that the existing core sample preparation mold does not have the ability to make cores with different sizes and different structural
