Renovation of the shaft Konradsberg

Renovation of the shaft in the area of the hanging inset roof and bottom of ventilation drift. Here, an advancing column made of glass fibre reinforced plastic (GRP) was used, which was made of 6 segments.

These single segments were assembled to the fibreglass formwork on the level of the haulage road, which was then lifted by a 12-ton hoist to the final position.

To realize the concrete work, the lower segments of the formwork were fixed with anchors on the roof of the haulage road. Concrete which was pumped from the haulage road to the bottom of ventilation drift into the ring space formed the connection of the advancing column to the ground.
