[0002] At present, grouting reinforcement is increasingly used in broken surrounding rock tunnels under special conditions in deep areas because of its functions of sealing surrounding rock cracks, improving rock structure, and improving rock mechanical properties. In order to achieve the best grouting reinforcement effect, it is necessary to control some grouting parameters, and grouting pressure and slurry flow are important parameters that determine the effective diffusion range of slurry. Therefore, real-time monitoring and recording of grouting pressure and slurry flow during the grouting process is very important for controlling grouting effect and optimizing grouting design. At present, grouting monitoring equipment and technology are relatively backward. Only the grouting pump pressure gauge can display the grouting pressure.
