PERI Civil Engineering Technology

For tunnel and bridge construction, a number of new systems have been developed over the past three years which have already impressively proved themselves during tough jobsite conditions.

The VARIOKIT heavy-duty truss girder

PERI has clearly expanded the application possibilities of the VARIOKIT engineering construction kit. With new VARIOKIT system components, it is now possible to also create a heavy-duty truss girder – as a suitable further development to supplement the VARIOKIT heavy-duty shoring tower. During the development, PERI took into account the load-bearing capacity of the tower as well as the challenging requirements of everyday construction work. The modular lattice system can be used for spans up to 40 m and is characterized by a very high load-bearing capacity. With the continuously adjustable telescopic support frame, all spans can be realized with centimetre precision. In addition, the calotte bearing allows easy adaption to the longitudinal and lateral inclinations of the superstructure. The heavy-duty truss girder can be quickly assembled by means of fitting pins. The compatibility with the VARIOKIT heavy-duty shoring tower through the VRB main beam, facilitates optimized solutions in the heavy-duty shoring sector, whilst the optional PERI UP scaffolding in the bottom section provides completely safe working conditions.

The VARIOKIT balanced cantilever equipment

With new components for the longitudinal direction of the balanced cantilever equipment, up to 5.75 m long segments can be concreted. In the transverse direction, existing system components are used. Thus, PERI achieves a maximum level of adaptability for a wide range of bridge sections. Furthermore, the moving procedure to the next concreting section is now extremely practiceoriented. Then, thanks to a newly developed mechanical solution, the required manual work is quickly carried out.

As all system components, with the exception of the tie technology, are available in the PERI rental parks, the balanced cantilever unit is also extremely costeffective with VARIOKIT. All modules incidentally can be re-used for future projects without requiring any further adaptation – the majority even for other types of civil engineering structures.
