VISUALIZED TEST METHOD WHICH IS FOR SINGLE FRACTURE GROUTING SEEPAGE AND IN WHICH WIDTH AND ROUGHNESS ARE VARIABLE

WIPO Patent Application WO/2023/160725

A9

A visualized test method which is for single fracture grouting seepage and in which width and roughness are variable. The method comprises: (1) designing a visualized test system for simulating a plurality of types of single fracture grouting seepage, which system comprises a water injection device, a constant-pressure gas injection device, a grout tank, a visualized single fracture seepage device, a rotary bearing device, and a computer; (2) adding grout prepared according to requirements into the grout tank; (3) constructing the visualized single fracture seepage device on the rotary bearing device according to test requirements; (4) adjusting an inclination angle of the visualized single fracture seepage device; (5) injecting the grout into the visualized single fracture seepage device to observe and study the migration process of the grout; and (6) cleaning the whole system after completion of the test. The entire process of fracture filling by means of grouting can be observed more intuitively by authentically and accurately simulating the migration and evolution process of the grout in rock fractures, thereby providing a platform for the study of the mechanism of rock fracture sealing by means of grouting.
