Tunnel drilling rigs (tunnel anchor drilling rigs) are engineering machinery specifically developed for tunnel construction under the new conditions of modern tunnel building.
Based on the unique characteristics of drilling and anchoring operations in tunnels, these rigs are specifically designed for drilling, anchoring, and maintenance within tunnels.
After specialized improvements and upgrades to small-scale drilling and anchoring equipment used in previous tunnel projects, tunnel drilling rigs (tunnel anchoring drilling rigs) were developed. These rigs not only possess functions similar to slope protection drilling rigs but also have the capability for drilling, anchoring, and other operations within tunnels. They eliminate the need for cumbersome procedures such as scaffolding erection and dismantling during tunnel drilling and anchoring.
Tunnel drilling rigs (tunnel anchoring drilling rigs) utilize tracked or wheeled mobility, allowing for all-weather operation within tunnels and easy relocation. This machine is compact and flexible; the drilling platform can rotate 360 degrees horizontally, tilted, and vertically, enabling horizontal, tilted, and vertical drilling. It allows for convenient and flexible all-around construction within tunnels, making it particularly suitable for challenging tunnel operations.
Equipped with a high-performance dual hydraulic power head or an automatic impact rock drill head, it achieves a comprehensive drilling and anchoring depth of 30 to 50 meters per hour. Its superior drilling and anchoring performance has been recognized by numerous construction companies and peers in various complex geological formations and drilling methods.
