The glass fibre segments are braced with diagonal Combar® bars in both directions to form a stable truss. This allows the entire reinforcement cages to be raised vertically above the 40-metre-deep shaft for the diaphragm wall without additional steel bracing, which represents a further optimisation of the construction process.

The easily machinable glass fibre reinforcement for the "Soft Eye" connects to the steel reinforcement. Schöck employees support the assembly teams during the work. Photo: Schöck Bauteile GmbH
The reinforcement cages made of glass fibre composite and reinforcing steel can be connected simply and efficiently using wire, clips, cable ties or rope clamps. Photo: Schöck Bauteile GmbH
The subgrade of the Paris Métro was stabilised using steel reinforcement cages and Schöck Combar® glass-fibre reinforcement. The diaphragm walls secure a shaft measuring 110 by 25 metres. Thanks to Combar®’s good machinability, the tunnel boring machine was able to pass through the reinforcement cages without any problems. The 33-kilometre-long tunnel of the ‘Ligne 15 Sud’ on the Grand Paris Express runs deep beneath the hustle and bustle of the Île-de-France region.
