high quality ground rock anchor bolt,Fully screw tie rod
Self drilling rock anchor bolt is a bolting solution for unstable ground conditions such as sand, gravel, silt, and clays, and in soft to medium fractured rock formations.
For projects facing above geo-conditions, hollow bar self-drilling anchor should be considered as the main solution cuz it's designed for optimized installation, tailored to the project's needs.
By drilling a hole in collapsing soil or loose lock, with a sacrificial drill bit an a hollow bar, and after the drilling operation injecting cementitious grout or resin into the hollow bar and surrounding cavity, it's a top solution choice.
(1) In the longitudinal direcition , rock body has equal tensile strength ,that is about 40% higher than the reverse-twist bolt in the same specification .
(2) Extend the support area , not only be used by end anchoring ,but also be used by fully anchoring ,that has a better support efficiency .
(3)Low price, widely used in coal mines, railways, hydropower and other types of roadway projects.
finish:yellow/blue/white zinc plated, hot dip galvanized
