Heavy-duty supporting system SL-1

The fast, cost-saving solution for tunnel-building

The modularly designed Doka heavy-duty supporting system SL-1 for tunnel formwork makes it possible to form widely varying tunnel cross-sections in a cost-efficient way, irrespective of the shapes and loads involved.

Highly cost-efficient

thanks to its flexible modular system 

Ensures efficient forming operations on every tunnel project, as

  • all system components can be rented
  • the system beams, walings and struts can be arranged in variable configurations, enabling optimum use to be made of each item of equipment
  • it is 100% compatible with Large-area formwork Top 50
  • it is exactly planned by Doka tunnel experts to ensure streamlined forming

Rapid working

right from the outset 

Optimized all-in-one concept for swift construction progress, thanks to

  • pre-assembly of the formwork and heavy-duty supporting-unit components, for short on-site erection times
  • fewer form-tie points as Multi-purpose walings WU 16 and Form-ties 20 are used
  • short repositioning times, achieved by the all-hydraulic formwork solutions
  • easier working conditions, thanks to the wide spacing between the parallel girder frame units, and the heavy-duty telescopic screw-jack system

Stringent safety standards

thanks to the ingenious system logic 

For reliable pro­tection at your site, achieved by

  • integrated working platforms and ladders
  • detailed assembly and utilization planning
  • safe travelling even on steep longitudinal and transverse gradients
  • tried-and-tested, pre-dimensioned system design
  • CE marking

The wide vault of one of the biggest tunnel caverns in Europe was formed using a tunnel formwork traveler that was divided along the middle. Separating the traveler into a left and right section made it very easy to assemble, and easy to reposition.
