(1) Introduction
The duplex coating rock bolt adopts two corrosion-prevention measurements on the bolt surface, hot-dip galvanizing and epoxy coating which can prevent corrosion very well. It is mainly used in conditions which are inflenced by underground water such as road, railway, water conservancy project, subsea tunnel, etc.
(2) Features
It is safe, reliable, and time saving.
Installation & operation are simple.
Choice of drill bits for different ground conditions.
Grouting works synchronize with drilling or after drilling. Grout can fill fractures effectively.
Anchor bars can be cut and lengthened according to your demands. It applies to narrow spaces.
(3) Application
Tunneling
Slope Stabilization
Soil Nailing
Micro Piles
Mining
Hydroelectric Station
