Title:
MICRO-FISSURE TRIAXIAL STRESS SEEPAGE GROUTING TEST SYSTEM AND USE METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/153501
Kind Code:
A1
Abstract:
Disclosed are a micro-fissure triaxial stress seepage grouting test system and a use method thereof. The test system comprises a micro-fissure triaxial stress seepage grouting experiment platform (1), a seepage grouting injection system (2), a liquid drainage pump (3), a first axial pressure liquid feeding pump (4), a confining pressure oil pump (5), and a second axial pressure liquid feeding pump (6). The micro-fissure triaxial stress seepage grouting experiment platform (1) comprises a micro-fissure triaxial stress seepage grouting experiment sealing device, a micro-fissure triaxial stress seepage grouting experiment support platform, and a pulling oil cylinder (8). A grating fiber optic sensor wiring column (9) is arranged at a left end of the micro-fissure triaxial stress seepage grouting experiment sealing device, and an acoustic emissions sensor wiring column (28) is arranged at a right end of the micro-fissure triaxial stress seepage grouting experiment sealing device. The test system dynamically monitors in real time the seepage grouting process of a sample under high axial pressure and high confining pressure and eliminates the technical defect of test systems in the prior art wherein difficulties in directly observing a dynamic change process of a micron-scale fissure means that the entire micro-fissure seepage process cannot be monitored in real time.
