Hydro-power plant Limmern

Full-round tunnel  formwork Hydro-power plant Limmern

Full-round formworks are expensive to design and manufacture. The
geometry and ring connector must be precisely adapted to the deformations of the concreting stage, otherwise it is impossible to strip
the ormwork later on. With the full-round formwork of the new pumped storage power plant in Limmern, there was also the additional difficulty of gradients measuring up to 22 % and exceptionally tight spaces.
