Visual test system for simulating grouting and seepage processes of fractured rock mass

Abstract

The invention belongs to the technical field of geotechnical engineering tests and provides a visual test system for simulating grouting and seepage processes of a fractured rock mass. The system aimsto solve a problem that visual detection of rock mass grouting and seepage migration processes under high and low temperature conditions cannot be realized in a simulation test. The system comprisesan experiment cabin system, a grouting system, a temperature control system, a water permeation control system, a rotary bearing system and a detection scanning system. The grouting system is used forinjecting grout to simulate the grouting process of a test piece; the temperature control system is used for controlling the temperature of a circulating bath lotion; the water permeation control system is used for conveying a seepage liquid; and the detection scanning system comprises a high-energy accelerator CT detection system and a PET detection system which are used for detecting slurry seepage migration and liquid fluid migration respectively. By means of the temperature control system, the grouting system and the water permeation control system, rock mass grouting simulation under thehigh and low temperature conditions can be achieved, and meanwhile real-time visual detection of the rock mass grouting and seepage migration process can be achieved through the detection 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 the 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 built structures, friction reduction and jacking of pipe jacking, etc. For tunnel engineering, grouting has a filling effect and reinforcement effect and antipermeation effect. The tunnel body is located in an area where groundwater develops, and a large amount of discharge may affect the local ecological environment. The waterproof and drainage principle of "mainly blocking and limited discharge" is adopted; the main functions of grouting are: 1) Reduce the seepage of surrounding rock and improve its resistance 2) dredging (partial wate...
