Horizontal borehole drilling rig machine is a specialized technique used in slope stabilization and reinforcement projects. The rig is designed for precision drilling of horizontal or near-horizontal boreholes into slopes, embankments, or unstable terrain to install anchoring systems, soil nails, or grouting pipes.

Mechanism employs high-frequency percussive action combined with rotational force, enabling efficient penetration through hard rock, dense soil, or mixed geological conditions.

During slope protection operations, the rock DTH drill rig is positioned at the designated slope face, and the drilling process begins by advancing the drill string horizontally into the ground. Compressed air or water is used to flush cuttings from the borehole while maintaining stability. Once the target depth is achieved, the hole is typically filled with grout or fitted with steel reinforcements to enhance structural integrity. This method minimizes ground disturbance, ensures precise alignment, and provides long-term stability against landslides or erosion. Its adaptability to complex terrains makes it ideal for infrastructure projects such as highway cut slopes, railway embankments, and retaining wall foundations.
