一、Equipment function
Rock triaxial testing machine, according to GB/T 50266-2013 "Engineering rock test Method Standard" and "Highway Engineering Rock test Rules" (JTG F41-2005), "water conservancy and Hydropower Engineering rock test rules" (SL264-2001) and other provisions, can be under servo control state, With the computer installed real-time display of rock triaxial software display axial loading force value (KN), confining pressure value (MPa), and with confining pressure regulation function. (Self-provided high-precision pressure regulator valve, when the confining pressure passively increases, can be manually adjusted to small, when the confining pressure is better than external reasons, can be manually adjusted to large.) Three indexes of axial test force, confining pressure and axial deformation can be dynamically displayed after completing the triaxial compression test of rock. It is applicable to the engineering properties of bedrock or surrounding rock under the action of engineering building load, and provides data for engineering geological evaluation and engineering building design.
二、Composition Introduction
1, host,
The main machine adopts high rigidity column type reaction frame.
2, three shaft chamber
The confining pressure loading of rock is realized by three axial chambers. The triaxial pressure chamber is compact and light. After pulling out with a push plate, the lower pressure plate can be removed manually. The specimen can be directly pushed out and replaced with a new specimen for triaxial test. (As long as the sealing sleeve replacement does not need to open the pressure chamber, abandoning the manual lifting of the pressure chamber cover operation).
3. Axial loading system
High precision software digital display, display loading force value, peak value, loading speed; In the servo control software to adjust the axial actuator for basic speed regulation pressure and achieve load protection constant pressure, loading speed can be adjusted to achieve constant speed control, and has the function of maintaining peak value or any force value, the software can display and save the loading process curve and data in real time.
4. Confining pressure loading system
High pressure loading system is used to control the pressure retaining pressure of the triaxial chamber. High precision software digital display, display loading pressure, peak value, loading speed; Under the adjustment of the servo control valve, the confining pressure actuator can be adjusted to achieve load holding pressure, and the loading speed can be adjusted. The software can display and save the loading process curve and data in real time.
