Multifunctional end cap system for triaxial rock mass permeation test

Abstract

The invention discloses a multifunctional end cap system for a triaxial rock mass permeation test. The multifunctional end cap system comprises an end cap base, wherein one end of the end cap base is connected to a water injection pipe, the other end of the end cap base is connected to a sealing ring, a diversion disc is arranged in the sealing ring, and bears against the end cap base in a connected manner, the diversion disc is provided with a central water outlet hole, the diversion disc on the outer side of the central water outlet hole is provided with more than one circumferential diversion grooves, the diversion disc is provided with more than one radial diversion grooves perpendicular to the circumferential diversion grooves, the radial diversion grooves are respectively communicated to the central water outlet hole and the circumferential diversion grooves, and the water injection pipe is communicated to the central water outlet hole. According to the present invention, the multifunctional end cap system can simultaneously achieve water guiding, water distribution, stress transmission, water sealing and other functions, can perform the permeation test on the complete rock core or the rock core containing the penetrating crack, and has the high test precision.

Description

technical field [0001] The invention relates to a multifunctional end cap system for a triaxial rock mass penetration test, which belongs to the technical field of rock mass hydraulic tests. Background technique [0002] Studies have shown that water is an important factor affecting the safety and stability of water conservancy projects, mining projects, and slope engineering. Statistics also show that 30% to 40% of hydropower engineering accidents, 60% of mine accidents, and more than 90% of rocky edge Slope failure is related to seepage of rock mass. Therefore, the study of rock mass hydraulics has important research value and engineering significance. Indoor test is one of the most important means to carry out rock mass hydraulics research. The key to experimental research lies in the development of test instruments. At present, triaxial permeameters are usually used to carry out rock mass hydraulics test research. [0003] The end cap is an important basic component in...

AI Technical Summary

Problems solved by technology

[0003] The end cap is an important basic component in the triaxial permeameter, which plays the role of distributing water flow and transmitting stress. However, due to the limitation of existing conditions, it is still difficult for the end cap to realize water conduction, water distribution, stress transmission, and water sealing at the same time. and many other functions
