The grouting device uses pressurized gas inside the device to increase the pressure inside the device to squeeze the slurry for grouting.

[0003] For example, the high-pressure grouting device for tunnel surrounding rock reinforcement with application number 202322032873.8 uses the second drive motor to rotate the gear, and the gear is meshed with the rack, so that the gear drives the moving block to move up and down on the rack, and the height of the grouting pipe is adjusted, which is convenient for adjustment according to the height of the surrounding rock. It has strong applicability and solves the problem of inconvenient adjustment. However, after analyzing the above-mentioned comparative patents and most existing grouting devices, it was found that most grouting devices require manual holding of the grouting rod for a long time to grout the borehole during grouting, and some grouting devices with fixed structures are difficult to form a good fixing and adjustment effect.
