Lochweidli Tunnel
Wattwil, Canton St. Gallen, Switzerland
Engineering, on-site services and a rentable tunnel system - the overall package scores
The Lochweidli Tunnel project in the Canton of St. Gallen is 305 metres long and principally of mining-type tunnel construction (so a good 30 blocks mostly underground) and has two portals at its entrance and exit points.
For Doka’s formwork experts the conditions of this particular project have been a baptism of fire for their new, rentable Tunnel system DokaMT - a preconfigured formwork traveller, with vibrator, concrete placing boom, pipework and filler necks; including carpenter-friendly bottom slab formwork and sealing carriages. A complete formwork traveller, modularly designed according to the modular design principle and comprised mainly of rentable components.
