Flood protection measures Schwieberdingen

In the recent past the town centre of Schwieberdingen was flooded several times during rainfall events in the area Stuttgarter Straße / town hall, the latest occurrence was on 04/07/2010 with heavy flood damage. The risk of flood in the town centre of the municipality Schwieberdingen is thus considered very high.

The following construction measures were taken:

Closure of the existing storm-water overflow above the overflow channel at Glemsbrücke

Extension of the existing overflow channel by about 300 m in downstream direction

New construction of a tank overflow structure in bottom position into the river Glems

New construction of a gully trap between throttle surge chamber and tank overflow structure

New construction of a throttle surge chamber with MID DN 300

The overflow channel is extended by means of prefabricated framework profiles made of reinforced concrete measuring 4,00/2,10 m.

The retention capacity of the storm-water retention basin Brühl amounts to approx. V= 3.142 m³ incl. gully trap. The gully trap has got a volume of approx. 136 m³.

Excavation: 13,800 m³

Rectangular channel: 310 m (124 prefabricated parts 4.50 m x 2.50 m x 2.50 m with 26 t each)

Throttle surge chamber, gully trap and tank overflow structure as prefabricated parts (heaviest individual part 66 t)

Soil nailing with sprayed concrete: 700 m²

Reconstruction Braunsbach after flood disaster – water engineering

Mountains of debris, tree trunks and mud

On 29/05/2016 there was an extreme rainfall in Braunsbach resulting in an enormous flood disaster. Small rivulets and v-shaped valleys rapidly turned into torrential mountain streams. The centre of Braunsbach was destroyed by debris avalanches and landslides. After the cleanup efforts and reconstruction of a temporary infrastructure the reconstruction started. The contract includes protection of the rivulet Orlacher Bach, as well as the reconstruction of the support walls including 2 bridge structures.
