SAXONY-ANHALT IS ALSO PREPARING FOR THE NEXT FLOOD.
Since the ‘flood of the century’ in 2002, Saxony-Anhalt has completed a whole row of flood protection measures, in particular to reinforce dikes. One weak point was the Elbtor in Schönebeck.
Since 2002, terra infrastructure has supplied large quantities of sheet piles, both hot and cold rolled, for protection against flooding from the Elbe. The profiles were used primarily in urban areas, e.g. in Dessau, for permanent flood protection. Nevertheless, there are still gaps at excessively high flood levels, such as the Elbtor in Schönebeck, a stone-paved ramp leading down to the Elbe and a protected natural site. If the river rises to a sufficient height, as was the case in 2002, it can flow through the Elbtor and reach the rest of the city.
To prevent this in the future, a flood protection system that can be dismantled was planned for the Elbe Gate in Schönebeck in 2010, using funds from the second economic stimulus package.
At the end of September 2010, the company Jaeger Spezial- & Tiefbau Bernburg began work on site. According to the detailed plans, flat and reinforced concrete foundations had to be constructed first, which were founded at a depth of 1.50 metres. Taking into account the requirements for buoyancy, sliding and tilting, the result was a very solid concrete foundation, 1.20 m wide at the base.
The upper part of the foundation, from 0.60 m to the ground, was poured into formwork, reinforced and contained the anchor plates for the posts, which had to be fitted into the reinforcement with millimetre precision. After the concrete had hardened, a test run for the removable flood protection wall could be carried out in November 2010.
The local conditions (longitudinal and transverse slopes in the area of the wall and compliance with the requirements of the preservation order) resulted in a wall with a relatively complicated geometry. The installation of tapered stop logs to compensate for different ground levels was unavoidable.
The test run went without any major problems. Flood protection teams, fire brigades and persons described by the client were given operating instructions for the wall and the necessary documents were handed over. The ‘real’ test for the flood protection wall is, of course, still to come – and it could come sooner than you think. The wall was erected on 14 January 2011, and on 20 January 2011, the water level had risen about 0.50 metres on the side. Result: a complete success, the removable wall is absolutely waterproof and does an excellent job of fulfilling its purpose.
