Product Description
What Is Split Sets Rock Bolt?
Split Sets are an efficient installation fortification element that works by friction and offers immediate support. It consists of a longitudinally grooved tube, with one end tapered for easy insertion into the borehole.
The Split Set is inserted into a hole with a diameter smaller than its outer diameter by impacting the bolt.
When the bolt is inserted into a smaller hole, forces are generated against the walls of the borehole, creating frictional resistance along the entire length of the bolt.
How the split set rock bolt Work？
Design: A Split Set consists of a high-strength steel tube, typically around 1.5 to 2.0 meters in length, with longitudinal slots or splits along its length. These splits allow the tube to compress radially when inserted into a drilled hole.
Installation: The Split Set is installed by inserting it into a pre-drilled hole in the rock or excavation face. As the Split Set is pushed into the hole, the rock's radial pressure causes the tube to compress, exerting outward pressure against the walls of the hole.
Anchoring: Once fully inserted, the Split Set locks itself into place within the hole due to the radial pressure exerted by the compressed tube. This creates frictional resistance between the Split Set and the surrounding rock mass, anchoring the unstable rock formation and providing reinforcement.
Support: The Split Set stabilizes the rock mass by redistributing stresses and increasing its overall strength. It helps prevent potential collapses, rockfalls, or other instability events by providing support and containment.
Compatibility: Split Sets are often used in conjunction with other ground support systems such as mesh, shotcrete, or cable bolts to provide comprehensive reinforcement and stability in challenging geological conditions.

how to install split set rock bolt
1. First, lay the steel mesh sheet along the top of the roadway, determine the hole position of the bolt according to the construction requirements, and then drill the hole with a drill pipe 1-2 cm larger than the diameter of the pipe seam bolt

Product advantage
2. High Flexibility: Grout volume and pressure can be adjusted to accommodate different rock formations.
1. Ease of Installation: Compared to other anchoring methods, slotted pipe bolts are relatively simple and quick to install.
3. Effective Reinforcement: Slotting allows grout to effectively penetrate rock fissures, increasing the bonding strength.
Applications of split set Rock Bolts
Applications of split set Rock Bolts
1 Tunnel and Underground Project
In tunneling and underground projects, self-drilling hollow rock bolts play a crucial role in initial support and stabilization. These rock bolts provide high-
pressure grouting to fortify soil or rock masses, ensuring surface stability and structural integrity within tunnels. According to the types of support in the tunnels, self-drilling hollow rock bolt can be divided into fore piling, radial support, tunnel-face support, locking the foot support and reinforcement of the tunnel portal.
2 Ground and Foundation Project
For ground and foundation projects, self-drilling hollow rock bolts serve as versatile solutions for micro-piling and structural reinforcement. These rock
bolts effectively transfer pressure, tension, or periodic loads to the surrounding soil, limiting deformation and enhancing foundation stability. They can be used as new building pile foundation, existing building structure repair, tower foundation, bridge reinforcement, soundproof wall foundation, protective screen pile foundation, anti-floating pile foundation, retaining beam anchoring and other different structural scenes.
3 Slope Stabilization Project
In slope stabilization endeavors, self-drilling hollow rock bolts offer robust anchoring systems to mitigate geological hazards and prevent slope instability. Slope stabilization is ensured by the entire anchoring system itself subjected to tensile and shear forces. It can be used as soil nail support, slope protection barrier, falling rock protection, retaining wall, embankment stability, roadbed reinforcement and other different application scenarios.
