Description

technical field

[0001] The invention belongs to the field of tunnels and underground engineering, and relates to an indoor test device for grouting rock mass against water pressure. Background technique

[0002] At present, there is no relevant test device in the field of durability analysis of grouting rock mass against hydraulic pressure. Products similar to the present invention mainly include various triaxial test devices, which are mainly used for conventional triaxial tests, rheological tests or related dynamic tests of soil samples or rock samples. The confining pressure application methods of such test devices are generally hydraulic, piston or servo loading systems, such as the triaxial rock tunnel rheological tester of China University of Mining and Technology (patent number: CN1087719A), the dual-piston multi-function of Tsinghua University Triaxial pressure chamber (patent number: CN1034806A), rock double linkage triaxial rheometer (patent number: CN101135622A) ...
