Features
High-strength spiral rib steel wire used to process the cable body helps boosts the anchoring force and load transmission properties of the anchor cable, smoothening out the surface of the cable body thus increasing support stiffness.
The cable body’s tail possesses a grouting joint that can instantly be attached to a grouting pump for high-pressure grouting. This design choice considerably optimizes the construction process by cutting out need for laborious procedure of tying grouting pipes and exhaust pipes on site.
