Rock bolting in tunnel made easy with our solutions
You don’t need to sacrifice quality for affordability, or vice versa.With Sinodrills, you get both.
self-drilling anchor tools used in tunneling
In tunneling, self-drilling anchor bolts are typically installed through the face of the excavation into the surrounding rock mass to reinforce the rock and prevent it from collapsing or breaking apart. The bolts can also be used in conjunction with shotcrete to provide additional support and stability to the tunnel lining.
Self-drilling anchor bolts are particularly effective in difficult ground conditions where traditional methods of rock reinforcement may not be feasible or practical. The bolts can be installed quickly and easily, reducing the time and cost of construction. Additionally, the bolts are able to withstand high loads and provide long-term stability and durability in the tunnel.
