How do Rock Bolts Stabilize a Slope?
The rock bolt tightly anchors the rock and soil of the unstable slope together through tension, forming a whole. It can effectively prevent slope slippage and collapse. The rock bolt can endure significant tensile forces, imparting ample anti-slip capability to the slope. This anti-skid ability plays a crucial role in preserving slope stability.
