Renovation work in Viereth
Using an exacavator with a drum cutter attachment from Kemroc
The flow control barrage at the village of Viereth am Main (Germany) went through major renovation work. The pillars to the side of the weir had to be modified to suit the design of the new weir gates. Specialist contractors JOHANN BUNTE Bauunternehmung Gmbh & Co. KG used a KEMROC KR 120 drum cutter attachment mounted on a 35-ton excavator to carry out the work. This combination provided maximum performance and precision while minimising viaration the cloud damage the historical structure constructed from plain, unreinforced concrete.
Dating back to 1925, the first barrage built on the river Main was at the Viereth near the city of Bamberg in Upper Franconia. In general, a river barrage is made up of three main components (to the general public, they are summarised with the word “lock”), and these are a lock for shipping to pass through, a hydro-electric power station and gated weirs. Combined, these components constitute a barrage whose main purpose is to control the flow of the river and maintain a constant water level. If there is to much water in the river, the weir gates are raised to allow more water to flow through safely. If the water level is too low, the weir gates are lowered so that the water level does not fall too rapidly …
