Tunnel system DokaCC
Efficient Tunnel formwork for cut-and-cover construction method
Highly cost-efficient
due to optimised system design- few shoring frames thanks to statically optimised load system
- reduction in temporary foundation expenditures thanks to the option of transferring loads into wall foundations
- lower labour costs due to fewer operating stations
High safety
in all stages of the job- project-specific detail planning by Doka Engineering
- horizontal pre-assembly and safe parallel-truss erection owing to screwed and tightly bolted connections
- safe up.down access thanks to built-in ladders with ladder cage
- high level of safety against wall foundation tilting and sliding thanks to optimised V-shaped strut angles
- safe operation of stop-end formwork due to large-area working platforms
- safe passage through longitudinal gradients up to ten percent using hydraulic drive
Rapid working
thanks to site-compliant system details- reduced assembly expenditures on site thanks to low number of shoring frames
- delivery of pre-assembled units to site leads to shorter assembly times
- simple lifting, lowering and fine adjustment forming wagon operations using hydraulic repositioning and lifting device
- quick forming and stripping of formwork panels using mechanical and fully-hydraulic stripping solutions
- easy opening and closing for stop-end formwork due to convenient gliding mechanism
System
Innovative system design
- system can be used on all foundation types
- forming wagon geometry allows for wide opening for passage
- loads are conveniently introduced into wall foundations
- no additional expenditures for foundations required
Less effort spent on assembly
- fewer individual components and shoring frames
- pre-assembled units
- faster assembly accelerates overall construction process
Optimal load transfer
- optimised diagonal strut angle
- relatively minor forces are introduced into the wall foundation
- added safety against tilting and sliding of the wall foundation
Utilisation
Rapid and easy lifting operations
Operations such as lifting, lowering and fine adjustments to the forming wagon are easy with the hydraulic lifting device. The innovative design ensures that the forming wagon remains securely on the rails without derailing even during lateral shifting. The result is accelerated progress since the forming wagon can be lowered directly onto the rails from any position.
Convenient stop-end formwork
- large-area platforms allow for adequate stripping paths
- stop-end formwork is convenient and quickly opened and closed
- easy to operate sliding mechanism readily exposes joint tape
High workplace safety
- Forming wagon DokaCC can be combined with proven Doka safety systems
- best-possible protection for site crew
