a first stage, GiB and Geophysica GmbH has tested innovative
thermo-active seal panels under laboratory conditions using
large-scale test sets. The development of the elements was carried out
in cooperation with NAUE GmbH & Co. KG. The experiments revealed
promising values of heat transfer capacity and heat transmission
panels are preferably suitable for application in areas of streaming
groundwater, since buildings need sealings in any case.
a second stage, we currently investigate the geothermal potential of steel
sheet piles. By energy sheet piles, newly developed by SPS Energy GmbH, an
energetic function is added to the static function of a conventional sheet
from the surrounding will be extracted by absorber pipes, which are
connected with the steel wall. Due to the numerous capabilities of sheet
piles within the fields of water engineering and special heavy constructions,
a wide range of applications opens for energy sheet piles. Energy sheet
piles are particularly
efficient, when the thermal energy of stagnant or flowing waters can be used.
The efficiency of such a system exceeds that of a solely ground-coupled heat
exchanger by a multiple.
to their great potential, energy sheet piles are the subjects of a research
project funded by the German Federal Ministry for Economic Affairs and
Energy. The objective of the project is to test and specify the performance
potential of activated sheet pile walls under controlled conditions with the
help of a large scale laboratory test equipment. On behalf of the Department
of Geotechnical Engineering (GiB), we develop numerical tools for the
planning and dimensioning of thermo-active construction parts such as
sealing elements and energy sheet piles.
