Description

Rock-like device for preparing crack position capable of being accurately adjusted Technical Field The utility model relates to the technical field of geotechnical engineering test equipment, in particular to a rock-like device for preparing a crack position capable of being accurately adjusted. Background The rock-like material test piece is an important experimental means for researching the mechanical properties of fractured rock mass, and is widely applied to the fields of mining, tunnel engineering, underground space development and the like. Defects such as joints, cracks and the like commonly exist in the natural rock mass, and the structures obviously influence the strength, deformation and damage modes of the rock mass. In a laboratory, a standardized test piece containing prefabricated cracks is prepared through an artificial mold so as to simulate the mechanical behavior of a real rock mass. In geotechnical engineering experiments, preparation of a rock specimen containing cracks is a core foundation for researching a rock mass destruction mechanism and a crack expansion rule, however, the traditional technology is limited by a fixed mold structure and a rough operation process, and long-term faces multiple bottlenecks, wherein the existing mold is mostly manufactured by adopting natural rock, for example, chinese patent publication No. CN212206812U discloses a rock specimen crack preparation device which is used for cutting the natural rock into a size matched with a containing groove, then placing the rock specimen in the containing groove, and fastening a rock specimen with a fixed block through bolts. The rock sample is drilled by passing a drilling tool through the cutting slot, and then a saw wire is passed through the drilled through hole to cut the rock sample along the cutting slot, thereby preparing a fracture. However, in the actual use, in the manufacturing process of cutting natural rock and the like, the shape and the specification of cracks are random, and repeated etching is not possible, so that the strength, deformation and damage modes of the rock mass are difficult to test in the actual test, defective products are easy to produce when the natural rock is processed, the processing difficulty is high, and the efficiency is low. Disclosure of utility model The utility model aims to solve the defects of random shape and specification, incapability of re-engraving, easiness in generating defective products, high processing difficulty, low efficiency and the like of natural rock cracks in the prior art, and provides a rock-like device capable of accurately adjusting crack positions.
