Lauenburg: demountable flood protection with the
TKR aluminium stop log system.
Huge numbers of people, huge quantities of materials, high
costs – that was the flood protection of the past, with sandbags.
These days, demountable protective walls, which can be erected
in a day, ensure dependable safety and good economics.
Lauenburg at the height of the summer. A few hundred metres
away, the River Elbe flows harmlessly past the old Palm Lock. But
this river can become a monster: normally 5 m deep, it can rise to
8.70 or even 9.12 m, as the floods of 2002 and 2006 proved. It was
only thanks to the time-consuming and costly intervention of the fire
brigade that the historic timber-frame building adjacent to Palm
Lock and the “Shun Lam” Chinese restaurant within could be saved
during those floods.
Traditionally, temporary protection against flooding is achieved with
piles of sandbags. However, when we consider the total cost, such
protection is often uneconomical because besides the production,
transport and placing of the sandbags, the high cost of their later
disposal as special waste must also be considered. The TKR aluminium stop log system from ThyssenKrupp GfT Bautechnik therefore represents an ideal solution. A reinforced concrete plinth and
a demountable flood protection wall will prevent flood-waters from
threatening the building in future.
In June the protective wall was erected for the first time by workers
from the local water board – as a test. “If we're not interrupted,
then the wall can be set up in a day,” explains Andreas Sassenhagen, the managing director of the water board. “It's a great
system,” says foreman Wolfgang Genczik enthusiastically. In total,
the water board has spent one million euros on securing the area
between the Palm Lock and the railway tracks adjacent to the ElbeLübeck Canal.

Optimum storage systems
Demountable flood protection in the form of a TKR aluminium stop
log system has been provided over a length of 80.50 m around a
tourist restaurant where the edge of the terrace for guests coincides
with the flood protection line. The 90 stop log elements can be
erected on the wall to the terrace to create a barrier 1.30 m high
as temporary protection against floods. The stop log elements are
kept in stores specially constructed for the purpose in a roll-off container with side doors.
Foundations.
The TKR aluminium stop log system is preferably founded on a
sheet pile wall. Such a wall ensures that the forces are reliably
transferred into the ground and prevents percolation and undermining. The flood protection wall is connected to the foundation
via anchor plates and concrete beams or directly to the top of the
sheet pile wall by means of a patented HOESCH system.
We can design individual flood protection schemes, including transport and storage requirements, for every situation, to suit the local
circumstances.
Facts & figures.
The TKR aluminium stop log system has proved itself as a temporary flood protection system in many situations – in terms of economy and ecology. One stop log panel, 2 m long, protective
height 1 m, corresponds to approx. 320 sandbags! The system
consists of just a few aluminium elements that can be assembled
to provide protective walls of various heights.

The height can be increased later, meaning that it is possible to
react flexibly and at short notice to changing conditions. Erection
is quickly completed with a small workforce. And easy handling
means that such a wall can even be built by unskilled labour.
