一种软岩加固用注浆设备
By designing a dual slurry tank and a support adjustment structure, the problems of existing equipment requiring shutdown for mixing and inflexible adjustment of the grouting pipe have been solved. This enables rapid switching of the slurry tank and flexible adjustment of the grouting pipe, thereby improving grouting efficiency and accuracy.

AI Technical Summary
Existing soft rock reinforcement devices only have one mixing tank. When the grout runs out, the machine needs to be stopped and remixed, which prolongs the grouting time. In addition, the adjustment flexibility of the grouting nozzle is poor.
A dual-slurry tank structure was designed, which enables rapid switching of slurry tanks via an electric push rod. It is also equipped with a support and adjustment structure to facilitate the adjustment of the angle and position of the grouting pipe, including components such as a turntable, adjustment frame, slide, and tilting frame, to achieve flexible adjustment of the grouting pipe.
It enables rapid switching of grout tanks, reduces downtime for mixing materials, improves grouting efficiency, and allows for flexible adjustment of the position and orientation of the grouting pipe, thus enhancing the flexibility and accuracy of grouting.
