New Motorway in Denmark
Silkeborg is located in Central Jutland Region, Denmark.
Landscape around the area is dominated by big lakes
and forests.To ease the traffic overload on road No.15
it was decided to build a new motorway from Silkeborg
to Aarhus. The road- and bridgework is scheduled to
be ready by 2016.
One of the contactors involved in the project is MT
Højgaard A/S, one of the leading contractors in the
Nordic countries. As a part of the big motorway project
MT Højgaard is in charge of a new bridge construction
over the Silkeborg Lake close to road 15 near Silkeborg.
The first step in building the bridge was to stabilize the
ground at the shoreline to enable cranes, which are
needed for the basement construction of the bridge
pillars, enter the job site. For this purpose MT Højgaard
used over 2000 timber piles up to 16 meters in length
and up to 300mm in diameter. This basement serves as
a bailey bridge for the construction machinery.
The timber piles were driven with Movax SP-70 Sidegrip
vibrator in combination with a drop hammer. The
cofferdam for the pillar basement is composed of double
sheet piles Type AZ 17-700 and 12 meter in length.
For the sheet piling MT Højgaard uses a Movax SP-70
mounted on a 34 ton excavator equipped with Movax
Automatic Steering system. Whilst piling, the excavator
is positioned on a pontoon.

MOVAX Mini Leader Rig MLR-15
Leader mounted Side-Grip vibro
for 7 - 21 ton excavators
Newest member of Movax-family, MLR-15, is made for
installation of tubular micropiles, H-piles or timber piles.
It is designed to meet the high position accuracy and
straightness demands for example at solar panel fields.
MLR-15 can use lightweight piling material because it
is able to take side-grip of pile close to ground level in
which case the flexibility of pile does not disturb the
driving process. Using lightweight piling material and
standard midi excavator for piling process reduces costs
of a micro piling project.
Movax MLR-15 can grip pile lying on the ground, lift it
up to vertical position, locate it and then drive it into
the ground with a straight linear movement. MLR-15
is easy to attach to standard excavators allowing easy
swap from carrier to another.
Side-grip clamps are quick change -type, which enables
fast change between different piling materials. There
are clamps available for steel tubes, H-beams and timber
piles. Customer can also request clamps for other
special pile profiles.
