A jig and method for precise positioning of rock joint particle filling angle

Abstract

The invention discloses a clamp for accurately positioning the placement angle of granular filler in a rock joint. The clamp comprises a clamp plate frame, sliders, fixing devices and connecting rods,wherein the sliders comprise a left slider and a right slider; the fixing devices comprise a left fixing device and a right fixing device; the connecting rods comprise a left connecting rod and a right connecting rod, a sliding chute is formed in the clamp plate frame, the sliders are located are located in the clamp plate frame and can horizontally slide along the sliding chute, one end of eachconnecting rod is fixedly connected with one corresponding fixing device, the other end of each connecting rod is hinged with one corresponding slider, and the connecting rods can rotate relative to the corresponding sliders in the clockwise direction or anticlockwise direction. The horizontal distance between granular filler can be adjusted, the granular filler can be placed in the preset position of the surface of the joint at any angle, and study of the transportation process and the crushing mechanism of the granular filler under the compression shear action is facilitated.

Description

technical field [0001] The invention relates to the field of rock mechanics, in particular to a jig and a method for precise positioning of rock joint particle filling angles. Background technique [0002] Natural rock mass includes rocks composed of minerals and joints and fissures. The mechanical properties of rock mass are jointly determined by the rock and the structural plane, and generally the structural plane has a greater influence on it. The existence of structural planes makes the mechanical properties of the rock mass complex and changeable. In addition, the fillings in the joint planes have an important impact on the stability of the entire rock mass. In the past ten years, many large-scale rock mass engineering-related engineering constructions, such as water energy resource development, oil and gas exploitation, underground storage of oil and gas energy, and geological disposal of high-level radioactive nuclear waste, have involved issues such as deformation s...

Problems solved by technology

However, there are still relatively few studies on the shear mechanics of granular materials, especially the experimental research on the migration process and crushing mechanism of granular materials. In addition, the arrangement of particles in the occurrence and rock joints is basically chaotic. The criss-cross pattern affects the study of the particle orientation and the mechanism of its migration process and fragmentation under compressive shear
