GROUTED ANCHOR
An innovative anchor that sets standards
Horizontal round steel tie rods generally represent the most cost-effective anchorage solution. However, if particular boundary
conditions, e.g. structures nearby, unsuitable soils just below ground level or refurbishment work on existing structures, mean that
horizontal anchors cannot be installed, then grouted anchors to DIN EN 14199 can be used.
Such anchors can be installed in changing subsoil conditions and in In addition, any type of wall connection is possible, e.g. upset thread,
various lengths and at various angles. eye rod or T-head joint.
The anchor forces are carried via skin friction between the pile and the
subsoil. In order to be able to assess the loadbearing behaviour of the
piles, we recommend tension loading tests to DIN EN 14199 and
„EA-Pfähle” (Recommendations on Piling, German Geotechnical
Society).
In contrast to round steel tie rods, it is not necessary to carry out any
excavation work to install anchor piles. A hinge is to be preferred to
fixity at the connection between sheet pile wall and head of anchor.
Such a connection permits rotation, which compensates for deflection,
settlement and installation conditions (see also EAU 2012).
Our grouted anchors can be fabricated with and without upset ends to
DIN EN 1993-5 in lengths of up to 35 m. Furthermore, each pile can be
extended to any length by welding or by using couplers. Yield stresses
of min. 355 to max. 590 N/mm² can be guaranteed depending on the
grade of steel.
