High precision concrete elements have been made for an Austrian tunnel project, with help from a versatile Liebherr concrete mixer.
A new 718 Liebherr Compactmix 1.0 plant is being used as part of a process in the manufacture of pre-fabricated concrete components. The Compactmix 1.0 compact mixing system was bought by a facility in Türkheim, Germany and its versatility has helped in integrating the unit into the plant's existing production hall. A conveyor belt for the concrete links the mixing system to the prefabricated part production section. The Liebherr ring-pan mixer Type RIM-M is equipped with a mechanical agitator system, and along with the sophisticated Litronic-MPS II microprocessor control package, allows high quality concrete to be produced to meet various requirements.
The Türkheim facility has been producing C40/50 concrete by using high-performance flow additives and quality cement.
The factory has been producing special parts for use in tunnel construction, which have to be manufactured to extremely high tolerances. The Türkheim facility has made a series of components for the second bore of the Pfänder tunnel in Austria, using a two-shift operation to make 19,500 segments in a 15 month time frame. The sizes of the formwork elements are different, and up to 5.8m³ of concrete is required per element. One single finished segment tips the scales at a weight of up to 15tonnes and these have then been supplied to the construction site near Bregenz to ensure just-in-time delivery.
