self drilling rock bolt installation

For the purpose of stabilizing rocks and soils, a self drilling rock bolt is an ideal solution. This hollow steel rod features a threaded end and can be conveniently screwed into a pre-drilled hole. Once in place, the bolt should be fixed into position with a nut and washer, while the remaining end may be distributed among anchors or soil nails.

A wide range of tasks depend on self-drilling rock bolts – from reinforcing foundations to stabilizing slopes, from digging tunnels to guarding towers with guy wires. Even concrete structures are supported by these trusty drill fasteners.

When selecting the ideal self drilling rock bolt, factors such as the size of the required drilled hole, the hardness of the targeted rock or soil, and the load that needs to be supported must all be taken into account. There exists a comprehensive variety of sizes and lengths to select from.

Turning a self drilling stone bolt is a quite straightforward job. Start by drilling a cavity – through rotary drilling, a hammer drill, or a jackhammer – that should be ever so slightly larger than the circumference of the bolt, then slide in the bolt itself. To finish, add a nut and washer to the end before tightening it securely with either an impact driver or wrench.

Once the bolt has been securely put into position, it can be totally encased in grout or cement to sturdily keep it in its rightful place. In certain situations, a sleeve may be wrapped around the bolt to ensure its durable shielding from weather conditions or to give it a more refined visual presentation.

An ideal solution for reinforcing both rocky terrain and soil, self drilling rock bolts are easy to install and more economical than other options. With the selection of sizes and lengths on offer, they guarantee an applicable result regardless of the task at hand. No special tools are required to install them, adding to their appeal as a preferred option.
