Water Retaining Structures

Traffic Project No.17, Navigation Crossing, Magdeburg, Germany - Hohenwarthe double sluice
During the lowering process of a ship the water masses flow ecologically and economically sensibly from the sluice chambers into the side basin in the principle of a double sluice. In the following lifting process the water is pumped back again. This saves up to 60% of the water.
Two 190 m long and 12.50 m wide sluice chambers were designed for this, in which about 320,000 m³ of concrete was to be placed.
The areas to be formed add up to 180,000 m². Around 12,000 m² of formwork was needed for this at peak times.

TRIO
SKS Single Sided Climbing System
|
 |
In areas of irregular cross-sections, such as for foundations, stopends, stairwells or side formwork, the flexible TRIO was used. The small number of different components required to connect the units together saved the formwork team a lot of walking and searching time, simplified the storage and the logistics. |

The site relied on the VARIO girder wall formwork with KG and SKS climbing brackets for the smooth, straight wall sections. Special steel rear tensioning reduced the number of ties needed and increased the possible concreting speeds.,The site relied on the VARIO girder wall formwork with KG and SKS climbing brackets for the smooth, straight wall sections.
