Tunnel system DokaMT

The fast traveller

The Tunnel system DokaMT is modular in design, offering an adaptable formwork solution for the typical cross-sections of mined tunnels. The variable-radius steel panels enable easy adaptation to different cross-sections.
Stations and lines
Mining method
Cut-and-cover method
Flexible standard system with durable steel form-facing. Many system components are rentable
Adaptability and re-usability of the systems
Steel panels SL-1 are robust, so high numbers of use cycles
Integrated working platforms and ladderways
Optimised stripping distances for cleaning the form-facing
Large drive-through access openings for site traffic
Clearly structured documentation from assembly drawings to risk assessment
CE mark is standard in Europe
Short planning times, because of few individual parts
Hydraulic formwork solutions and electric driving units for fast cycles
Pre-assembled units and standard system parts keep assembly times short
Formwork and expertise from a single source
Doka is your full-service partner on complex tunnel projects – from planning through project management to solutions that work, complete with fully integrated concrete placing and external vibrators – everything from a single source.
Repositioning gantry
Large drive-through access openings, so site traffic is not obstructed.
DokaMT has been used on end-to-end bottom slabs and also on strip foundations.
Sustainability due to
re-usability and high proportion of rentable components
Variable-radius steel panels
The steel panels adapt easily to the structure's radius during assembly and are re-usable on widely differing projects.

Project highlights
Preconfigured forming wagon
Rentable modular-kit principle
Bypass for transit traffic
At the touch of a button
Both the hydraulics and the electric driving units have pushbutton control.
