The self drilling hollow anchor bolt is the important element of the flexible supporting system. The functional mechanism of the hollow anchor bolt combined arch depends mainly on the reinforcement effect from the systematic hollow anchor bolts to the whole surrounding rock. It will help the surrounding rock to form arch bearing structure in a certain depth range, and to bring its high compressive strength into full play.
As with any anchoring project, it is important to keep safety in mind and follow instructions carefully. Always remember to wear safety goggles, handle all tools with extra care and follow all technical specifications. This article is meant to serve only as a basic explanation of concrete hollow anchor bolts. Always refer to manufacturer's instructions or consult a contracting expert during any anchoring project.
