INFRA-KIT Tunnel Applications
Variable-use tunnel carriers for the efficient production of cut and cover or mining tunnels
Our Infrastructure Competence Centre provides comprehensive solutions for any type of tunnel construction. With our experienced engineers, working together globally to find the best solution for you, we have completed numerous tunnel construction projects with various structures and shapes and in different countries all around the world.
Application
Application examples
Many of the applications can be achieved with standard materials, which keeps costs low. Hünnebeck also has vast experience with customised tunnel solutions; moreover, we can provide prototype machines adapted to the project’s needs. Customised equipment is usually equipped with hydraulic jacks and spindles with external vibrators, a concrete distributor and an electrical or hydraulic repositioning system. A single remote control can be designed to move and operate the formwork as requested.
Motorway tunnels
Railway tunnels
Water tunnels
Product advantages
With our systems, we support all kinds of tunnel construction methods:
- Open cut, monolithic and partly monolithic
- Mine
- Cut and cover construction method
- Special construction methods

Our global Infrastructure Competence Centre
The centre is focused on creating solutions for bridge and tunnel structures. It also incorporates the experience of Hünnebeck’s engineers and its development centre. It is a virtual centre - an engineering community - in which employees from different locations around the world are involved. When providing tunnel structures anywhere around the globe, these experts can, for example, estimate costs and support the planning of scaffolding and formwork. If necessary, they can also develop individual solutions or make suggestions for the optimal organisation of logistics.
Services offered:
- Design and engineering
- Redesign and engineering for old machines (retrofit to the new geometry)
- Site supervision
- Assembly service
Related products
All Hünnebeck tunnel solutions are based on just one system: The modular beam-kit system INFRA-KIT, which offers maximum flexibility with just a few components. INFRA-KIT is equipped with numerous intelligent and sophisticated features and can be rented for different tunnel applications. Pre-assembly is possible.
