In the course of construction, we often need to anchor and support rock formations in unstable areas. In the last century, bolting support has emerged. Now the most commonly used anchoring support method is self drilling rock bolt. Compared with traditional bolts, what is the improvement of self drilling rock bolt?
The self drilling bolt integrates drilling, grouting and anchoring, and the one-way operation significantly improves the construction efficiency. Anchoring at the same time as drilling reduces the drilling failure rate and makes the anchoring effect better. It can be installed with a small drill or a hand-held hammer, allowing applications to reach difficult or limited access areas. This means that slope protection can be performed in difficult areas through better functional anchors.
Compared with the traditional bolts, self drilling bolts require a smaller operating area. In the development of tunnels, mine roadways, and underground spaces, there is more space for construction and more material savings. Since the construction of self drilling bolt has little noise and has minimal impact on the surrounding buildings, therefore it is very popular in urban construction and maintenance of ancient buildings.
