Abstract
The application discloses a weakly cemented rock grouting consolidation test device and method. The weakly cemented rock grouting consolidation test device comprises a shell, a cover plate and a grouting assembly. The first end of the shell is provided with a seat plate. The seat plate is provided with a limiting groove for mounting a weakly cemented rock test piece. The second end of the shell is open. The cover plate is detachably connected with the shell to seal the second end of the shell. The grouting assembly is provided with a grouting pipe. The grouting pipe is connected with the cover plate and communicates with the inner cavity of the shell. The grouting assembly is used for injecting grout into the inner cavity of the shell. The weakly cemented rock grouting consolidation test device can perform grouting test on weakly cemented rock, has high data reliability and is helpful to optimize and guide the reinforcement of weakly cemented rock stratum in mine engineering.
