Heavy-duty supporting system SL-1
The heavy-duty 'construction kit' for tunnel-building
Highly cost-efficient
as it is superbly adaptable
- minimises investment costs because many of the system components are rentable
- the system beams, walings and struts can be arranged in variable configurations, enabling optimum use to be made of each item of equipment
- flexible in terms of construction workflow, as it is compatible with Large-area formwork Top 50
- is exactly planned by Doka Formwork Experts to ensure streamlined forming
Fast construction progress
achieved by optimised overall concept
- short set-up times, thanks to pre-assembled formwork and HD supporting-unit components
- fewer form-tie points, as Multi-purpose walings SL-1 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 girderframe units, and the heavy-duty telescopic screw-jack system
Exceptionally high workplace safety
thanks to the built-in safety systems
- safe work locations assured by integrated working platforms and ladderways
- detailed assembly and utilisation planning makes for executional reliability
- safe travelling even on steep longitudinal and transverse gradients
- reliability assured by tried-and-tested, pre-dimensioned system design
- safe placing of reinforcement steel, from the Working scaffold Modul
