Benefits & Features
The rock bolt damping nut is a pre-assembled damping nut that improves upon the traditional rock bolt. Its key feature is that the damping nut is pre-installed on the rock bolt shank and securely connected via a pinhole or pin. This allows the shank to be advanced and the support plate to be tightened simultaneously during the anchoring process. Its simple structure makes it less likely to lose, making it suitable for anchoring applications requiring a preset opening torque, such as tunnels and slopes.
Structure and Function
Pre-installed damping nut:
The damping nut is pre-assembled and secured to the rock bolt shank prior to installation.
One-Stop Operation:
During anchoring, the shank can be advanced and the support plate tightened simultaneously, simplifying the installation process.
Advantages
Simplified Installation: Reduces installation steps and improves efficiency.
Stable Structure: The nut is less likely to be lost before or during installation.
Reliable Performance: Ensures that the damping nut functions at the preset opening torque during anchoring. Applicable Scenarios
This rock bolt damping nut is suitable for projects requiring a predetermined opening torque for rock bolts and placing high demands on ease of construction and reliability.
For example, in geotechnical projects such as tunnels, mines, and slope support, this rock bolt damping nut can effectively improve support stability.
