Abstract

The present invention belongs to the field of rock and soil engineering test technology. It provides a visual test system that simulates cracks -containing rock body grouting and infiltration process. It aims to solve the process of simulation tests that can not be achieved in high and low temperature conditions.The problem of visual detection, this system includes the experimental compartment system, grouting system, temperature control system, water transmittance control system, rotation carrying system, and detection scanning system; the grouting system is used to injected the grouting process of the simulation of the slurry.The temperature control of the circulating bath liquid; the water transmission control system is used to transport the infiltration fluid; the detection and scanning system includes a high -energy accelerator CT detection system and the PET detection system, which are used to detect the flowing flow of the slurry and the liquid fluid transport.Through the temperature control system, grouting system, and water transmission control system provided by the present invention, the rock body grouting simulation under high and low temperature conditions can be achieved. At the same time, the real -time visual testing of the rock body grouting and seepage transportation process can be achieved by detecting the scanning system.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering tests, and in particular relates to a visual test system for simulating grouting and seepage processes of rock masses containing cracks. Background technique [0002] Grouting technology plays an important role in anti-seepage of underground structures, reinforcement of foundation pits, prevention of ground subsidence, foundation treatment of constructed buildings, and pipe jacking to reduce friction and jacking. effect and osmotic reduction. The tunnel hole is located in the area where groundwater is developed, and a large amount of discharge may affect the local ecological environment. The principle of "mainly blocking and limited discharge" is adopted. The main functions of grouting: 1) Reduce the seepage of surrounding rock and improve its resistance seepage capacity and reduce the seepage flow of groundwater; 2) dredging (locally water blocking) water flow, improving enginee...
