bauma 2004: Interested visitors on the Thyssen-
Krupp stand
ThyssenKrupp GfT Bautechnik
presents itself at the bauma more
successfully than ever before
Every three years, the bauma, the world’s largest
specialist construction trade fair, opens its doors
in Munich. This year, the international construction
machinery and construction material machinery
industry sectors met from 29 March to 4 April. The
trade fair's management says that it was the most
successful bauma in its fifty year history. 410,000
specialist visitors from 171 countries came to gather
information over seven days in the halls and
on the gigantic open area of the trade fair. Manufacturers
showed a number of worldwide innovations
occupying an exhibition area of 500,000
square metres. ThyssenKrupp GfT Bautechnik
presented itself in the open area F8, block 806
A/1, occupying 600 square metres. “The per-
centage of foreign visitors and of them, those from
Central and Eastern Europe and Asia, continued
to increase. We have concluded a number of
interesting orders directly at the trade fair,” said
ThyssenKrupp GfT Bautechnik Managing Director
Christian Walter, viewing the results of the trade
fair positively. ThyssenKrupp GfT Bautechnik
demonstrated an integrated range of sheet piles,
pile driving, extracting and anchoring equipment,
trench sheeting and flood protection systems for
port and civil engineering. This year, there was a
bauma world premiere for a HOESCH sheet pile
wall, using the LARSSEN system. This HOESCH
steel sheet pile wall is 750 millimetres wide, making
it particularly economic. Another world premiere at
the bauma was for cold rolled sheet piles, which
are used for embankment consolidation as well as
for culvert construction and flood protection.
The worldwide largest MS-62 HV vibrator, which
has since been used at a German construction
site (cf. page 8), caused a stir among the experts.
The new economic HOESCH H 3600n Z-section,
the Peiner PZ 675-12 intermediate section, the
trenching system GIGANT with new double slide
rail (cf. page 9), as well as the Aqua-Stop-Damm,
which can be used in the place of sandbags when
there is flooding, all also aroused the visitors’ interest.
The management and employees of Thyssen-
Krupp GfT Bautechnik were very satisfied with
events at the bauma: several thousand visitors
were provided with information. Specific projects
and requirements were discussed with many of
the visitors. �
Vibration-free insertion of sheet piles section at
the Teltow Channel
First use of the HOESCH pile section
H 3600 n using the Giken press
Within the framework of the building measures of
the Teltow Channel in Berlin the HOESCH sheet piles
walls perform important functions. For a pipe drive
under the channel it was necessary to construct
a starting and target pit on both sides. For the
remaining sheet pile wall along the shore the new
HOESCH sheet pile section 3600 n was used. As
the stability may not be impaired in the immediate
vicinity of a building development the sheet piles
had to be pressed in by applying the Giken presses
ZP 150.
The company carrying out the construction, Ernst
Meyer, Berlin and in particular the local press
crew were impressed by the excellent behaviour
of the sheet pile section for which the stable locks
were responsible. Further construction work awaits
execution at the Teltow Channel. Also in this
instance it is intended to press in steel sheet pile
walls in order to secure the shore. The construction
method of using steel sheet pile walls and in
particular the HOESCH profiles has been shown
to constitute an economic solution. �
Self-boring drainage pipes
ensure non-slip slopes
Heavy rainfall and melting snow after a sudden rise
in temperatures may lead to dangerous slippages
on slopes and embankments. So as to take effective
precautions against this risk at a reasonable
economic expense, ground nails in accordance
with DIN 21521 are used. These nails secure the
natural stability of the ground, resulting in a new
composite material which has a high load capability.
The anchoring system, which is manufactured
by Friedr. Ischebeck GmbH and which is marketed
by ThyssenKrupp GfT Bautechnik, has now been
supplemented by the addition of a new system
for draining slopes: the TITAN 40/20 self-boring
drainage pipes. Homogeneous, fine-grained and
permeable soils such as sand and coarse clays
are particularly susceptible to the feared slope
slippages. When it rains heavily, the seepage
water penetrates into the permeable upper soil
and, when it meets impermeable strata such as
made of rock or boulder clay, it is held back. The
static friction of this separating surface is thereby
dangerously reduced, the water-saturated upper
