Visual device for simulating accumulation effect of fractured rock mass grouting particles

Abstract

The invention discloses a visual device for simulating the accumulation effect of fractured rock mass grouting particles. The visual device consists of a slurry basic parameter measurement system consisting of a pressure gauge and a flow meter and a grouting simulation system consisting of a grouting pipe, a seepage pipe, a rigid plate, flexible rubber and a rigid pressing plate. Under the synergistic effect of the slurry basic parameter measurement system and the grouting simulation system, the grouting effect of cracks with different occurrence parameters and the grouting effect of slurry with different components under specific crack parameters can be simulated, and the engineering problem that the engineering rock mass grouting process and the grouting effect cannot be visually evaluated can be solved.

Description

technical field [0001] The invention relates to the technical field of engineering rock mass, in particular to a visualization device which can be used to simulate the accumulation effect of grouting particles in cracked rock mass. Background technique [0002] Under the action of tectonic stress, the engineering rock mass will breed a large number of primary cracks, and a large number of secondary cracks will also be formed during the dynamic construction process. When the above cracks penetrate or are adjacent to the confined water source, it will pose a safety hazard to the engineering construction. At present, the water blocking effect achieved by engineering technicians by filling rock mass fissures with grouting can only be estimated and judged based on relevant engineering experience, and it is impossible to visualize and quantify the water blocking process and effect of grouting. In addition, as far as the current laboratory conditions are concerned, most of the rese...

At present, the water blocking effect achieved by engineering technicians by filling rock mass fissures with grouting can only be estimated and judged based on relevant engineering experience, and it is impossible to visualize and quantify the water blocking process and effect of grouting

In addition, as far as the current laboratory conditions are concerned, most of the research methods in this area are the research on the grouting effect of composite multi-dimensional cracks of large-scale rock mass and similar simulated materials. Relevant monitoring equipment and analysis software are used to explore the grouting effect, but there are still some differences between the research results and the grouting effect on the project site, and it is impossible to truly restore the visual effect of on-site grouting. In view of the limitations of current testing methods and equipment, the above engineering problems It has been perplexing engineering technicians and scientific researchers in related fields, and it is difficult to obtain effective solutions
