SELF-DRILLING Anchor Bolt
Self drilling anchor system for application in soil nailing, rock bolting, micro-pipling, tunneling, mining and infrastructure.
WHAT IS SELF-DRILLING ANCHOR SYSTEM?
Self drilling anchor system is a type of ground anchor used to provide stability in soil or rock formations. The system typically consists of a Hollow Anchor Bar with a drill bit on one end and a coupling on the other. During installation, the drill bit is used to bore a hole into the ground while simultaneously injecting grout into the hole to fill any voids. The anchor bar is then inserted into the hole and the grout is allowed to set, creating a bond between the anchor and the surrounding ground. This creates a stable foundation that can support a variety of structures and engineering projects. Self drilling anchor systems are commonly used in construction, mining, and tunneling applications.
Hollow anchor bar is the body of a self-drilling anchor, as a hollow steel tube with an outer round thread, hollow anchor has the sacrificial anchor bit connected at one side, plate and nut connected at the other; two Hollow Anchor Bars could be connected together via a coupling, for duties that requiring longer anchors.
