A Split Set is a type of rock bolt commonly used in ground support applications in mining, tunneling, and civil engineering. It is designed to provide reinforcement and stability in rock structures by anchoring unstable rock formations and preventing potential collapses or failures.
Here's how a Split Set works:
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.
Split Sets are valued for their simplicity, reliability, and ease of installation. They are particularly useful in ground conditions where other types of rock bolts may be less effective, such as in fractured or unstable rock formations. Split Sets offers an efficient and cost-effective solution for ground support in mining, tunneling, and civil engineering projects.
