The C-14 full-hydraulic multifunctional ground improvement equipment is designed for small-section tunnels and coal mine roadways. It integrates drilling, water stopping, drainage, and grouting functions. With a full-hydraulic drive system, it adapts well to complex environments and enables multi-angle operations (vertical, horizontal, inclined). Its intuitive interface allows quick parameter adjustment even in narrow spaces, enhancing efficiency and safety in underground projects. It is an ideal solution for ground reinforcement and hydrological control in mines and tunnels.
