Abstract: A pressure-controlled tunnel directional grouting reinforcement device is provided. Some embodiments of the present disclosure utilize the pressure generated during the concrete injection serves as a power source, and changes the directional movement of the front conical block, the rear conical block, and the actuated sleeve valve inside the interface pipe. This allows the concrete grout to be injected in a relatively low-pressure state and to be injected into an inner structural layer in a relatively low-pressure and stable state. The objective is to preserve the high-pressure state of the concrete grout during injection, and to reduce the damaging effects caused by high-pressure erosion of the concrete grout on the inner structural layer. To reduce the damaging effects of the high-pressure erosion on the inner structural layer by the concrete grout. An active pressure compensation is further employed to interfere with a pressure fluctuation state of the concrete grout.
