Description

Technical Field

[0001] The present invention relates to the technical field of rock testing equipment, and in particular to a rock uniaxial compression testing device and a construction method thereof. Background Art

[0002] Chinese invention patent CN205280497U discloses a rock uniaxial compression test device and its construction method. It consists of a base, a glass cover, and an observation system. The base is disc-shaped with an annular groove on its upper surface. The glass cover is an inverted barrel with a diameter matching the annular groove on the base, a circular hole at the top center, and an open bottom. The observation system, including a high-definition camera and LED light, is located inside the glass cover and connected to the base via a metal hose. This device prevents rockburst injuries during test loading and enables simultaneous observation of both the interior and exterior of surface cracks, improving the quality of surface crack extension tests under uniaxial conditions.

[0003] Although the above patent solves the problem of rock burst injuring people during test loading by providing a glass cover on the rock, during the rock test, the rock burst will generate dust, which will easily adhere to the inside of the glass cover, causing the dust to block the glass cover, thereby affecting observation and recording.

[0004] Therefore, we made improvements to this and proposed a rock uniaxial compression test device and its construction method. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem of rock burst injury during test loading by providing a glass cover on the rock. However, during the rock test, the rock burst will generate dust, which is easy to adhere to the inside of the glass cover, causing the dust to block the glass cover, thereby affecting observation and recording.

[0006] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:
