Tunnel construction is an advanced engineering process that requires the use of specialized drilling tools to carry out this complex work efficiently and safely. In this article, we will introduce the types of tools used for this purpose and discuss the use of innovative solutions that allow even more efficient rock excavation.

What drilling tools are used in tunnel construction?

Tunnel construction is a task that requires precision and the right choice of drilling tools. Among them, there are several basic types that allow efficient and fast movement through soil or rock. The first is the commonly used tunnel boring machines (TBMs), which use a rotating disc cutting system to remove material from the front of the machine. This makes it possible to simultaneously excavate a tunnel and install its casing.

Another type of drilling tools are percussion drill rigs, which use impact energy to crush rock. They are mainly used in the construction of short sections of tunnels or in areas with geology that is difficult to predict. Percussion drillers allow for fast and precise tunnelling of small sections. In the case of tunnel construction in the ground, on the other hand, disc-drilling methods are also used, which involve the use of special cutting discs. These discs are mounted on a rotating drill head, which allows simultaneous removal of material from the front of the machine and installation of the tunnel casing.

Use of modern technologies in tunnel construction

Modern technologies play a key role in the tunnelling process, allowing to reduce working time, increase safety and minimize the environmental impact of the work. One such solution is the GONAR self-drilling system, which allows remote management of work and monitoring of machine parameters. This makes it possible to respond quickly to changes in geological conditions and optimize the tunnelling process.

Another innovative solution is the use of 3D technology in tunnel planning and design. By using specialized computer programs, it is possible to accurately plan the route of the tunnel and its construction, thus avoiding possible problems during the implementation of the project. It is also worth noting the growing use of robotics in tunnel construction. Robots are used both for tunnelling and conducting inspection work. This makes it possible to increase efficiency and reduce the risk of accidents.

In conclusion, drilling tools and modern technologies play a key role in the tunnel construction process. Their use makes it possible to reduce the time of project implementation, increase safety and minimize environmental impact. As technology develops, further increases in the efficiency and quality of projects in this field can be expected.
