Rock anchor is installed into the unweathered rock to develop the full strength and stability of the anchor rod.
The rock anchor features triple eyes that provide space for up to three guy connections. A hole of the specified size is drilled into the rock and it should be in line with the angle of the guy. The rock anchor is inserted and a bar that passes through the eye turns the rod.
The eye grooves of the rock anchor are contoured to prevent the guy strands from kinking, bending, or even spreading.
The good thing about rock anchor is it does not require a wrench for the installation. The design of the anchor gives allowance for self-installation.
The ability of the anchor to bore through rocks also helps to save time and the cost of labor that is required for the boring process. When it comes to drawing a comparison, the cost of installing rock anchor is way lesser than that of installing through the grouting method.
Rock anchor is galvanized according to the ASTM A123. Its wedges are coated with a rust inhibitor which ensures that it lasts for long regardless of the environment of the installation. It also has high tensile strength that makes it withstand all sorts of forces.

After buying a rock anchor, the next step is to proceed with the installation. Here are the steps for installing a rock anchor:
The first step is to drill a hole whose diameter is equivalent to that of the rock anchor. The depth of the hole should also match the length of the rock anchor. The high levels of accuracy that is needed means that you should get the most advanced drilling machines.
During the drilling, it is vital to consider the issue of alignment. The hole should be properly aligned. The optimal diameter difference between the hole and the anchor should range between 4mm and 10mm.
Before you inject the grout, ensure that you clear the drill hole to remove any traces of debris. You can then proceed to fill the hole with the grout. However, you should leave out a small space at the top of the anchor hole. This will provide room for expansion.
Insert the sheathed threaded anchor down the grouted anchor hole. Ensure that it goes down to a depth that will leave the desired length that you want to work with sticking out. The function of the sheath is to prevent the threaded anchor from bonding with the grout. Once the anchor is in a perfect position, you can remove the sheath.
Proceed to install the steel bearing plate to the part of the rock anchor that is outside the hole. You can then bolt the plate into a perfect position.
You can now pull the anchor using a prescribed tension and a retaining nut. Lock it well to prevent any cases of future movement. Tensioning gives rock anchors strength and tenacity to withstand all kinds of forces.
Why should I choose a rock anchor over other devices? There are numerous benefits that you will gain from using rock anchors.
A rock anchor provides a cost-effective solution for reinforcement. The gravity foundation, which is usually used as an alternative to rock anchor is quite expensive to install. With rock anchors, you will not spend a colossal amount of money on the supporting components.
Rock anchors are also easy to install. You will not have to construct reinforced concrete or follow complex installation procedures.
Also, you do not have to excavate large areas to install rock anchors. You only need to drill a small space and you will be through with the installation process.
