What is a tunnel drilling rig?
Tunnel drilling rig is a specialized mechanical equipment used for tunnel construction. Its main task is to perform drilling operations inside the tunnel, while also having other functions such as anchor rod installation.
The tunnel drilling rig adopts advanced technology and design, which enables it to efficiently and accurately complete drilling tasks in the special environment of tunnels.
There are various types of tunnel drilling machines, and different models and configurations of drilling machines can be selected according to specific work requirements and environmental conditions. For example, some tunnel drilling machines may be equipped with tracked walking mechanisms to move freely inside the tunnel; And some may use special stabilization systems to ensure stability during the drilling process.
Functions and characteristics of tunnel anchoring drilling rig
1. Compact in size, flexible and convenient
The tunnel boring machine has been specially designed for tunnel working conditions, making the body smaller and easier to move and operate inside the tunnel. This has extremely high practical value for tunnel construction environments with limited space.
2. Multi angle rotating drilling rig
The drilling platform of the tunnel anchoring drilling rig can achieve arbitrary rotation in the horizontal, inclined, and vertical directions of 360 degrees, meeting various needs such as horizontal drilling, inclined drilling, and vertical drilling inside the tunnel. Greatly improved construction efficiency and quality.
3. Excellent drilling performance
The tunnel anchoring drilling rig is equipped with high-performance hydraulic pneumatic self impact rock drilling heads, which are suitable for drilling in various complex formations and different drilling methods. In practical applications, its excellent drilling performance has been recognized by a large number of construction units and peers.
