TensarTech® zidni sistem TR2
If a structure is needed in temporary works, such as a retaining wall or bridge abutment, practicality and economy typically take priority over aesthetics. The TR2 system has been designed to produce temporary structures which are straightforward to build, with face angles between 60° and vertical, for a lower cost compared with traditional reinforced concrete, as well as seeing use as permanent thrust relief structures.
The system is comprised of steel mesh face units - lined with durable, heavy duty geotextile - securely connected to Tensar uniaxial geogrid
soil reinforcement via Tensar’s highly effective bodkin connection joint. There is no requirement for an external face support or formwork, owing to the rigid steel mesh face being braced internally and held in place by the geogrid and fill material during construction.
Due to having a design life of up to 120 years, the Tensar
Tech TR2 System can also see use as thrust relief structures. This may be used in the case where an existing retaining wall which must remain in service is unable to take the lateral earth pressure being applied by the backfill (for a design life of more than 60 years, the steel face is usually supplied galvanised), or to reduce or remove earth pressure from acting on buried structures.
