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.

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
