    DESIGN OF MODEL TEST SYSTEM FOR GROUTING UNDER HIGH PRESSURE CONDITIONS

    • Grouting works are often executed under the geological environment of high formation pressure and high water pressure(such as warer shutoff or rock reinforcement in coal-mine).In order to study the flow characteristics of grouting slurry spreading under high pressure conditions,the author developed a grouting test system which can creat a high-pressure environment of over 5MPa.The test system consists of four functional modules,and can be divided into four equipment subsystems.The core equipment of the test system is the patent product Test Set-up for Simulating High Pressure Grouting,in which pressure transmission pipes are used as the solution to problems such as size effect,sensor corrosion-preventing and high-pressure sealing,which are encountered in designing the monitor program inside the high-pressure tank.
