Self-drilling Hollow bar anchor system
Self-drilling hollow bar anchor systems are mainly used in slope and excavation stabilization, tunneling support, foundations with micropiles. It is also widely used in the road, metro and railway projects. Unconsolidated ground conditions favour the self-drilling anchor bolt technique for fast and simple method of installation compared to the traditional casing method.
It can be installed in difficult sites with weak rocks, loose soil, weathered layers, sand with stone layers where it is difficult to create and maintain an opened drilled hole for inserting ground anchors.
- Self drilling hollow bar anchor system has two performances: drilling and grouting. It features a hollow bore for flushing, or simultaneous drilling and grouting.
- Self drilling anchor hollow bar anchor system is reliable, efficient and convenient, which makes high piling output possible.
- The durability of the system can be improved by galvanising as well as powder coating with epoxy.
