Whenever with TBM excavations it is necessary a subsequent demolition or removal of the precasted segments , it becomes very convenient to utilize, in place of the metal reinforcements, GRP ones that can be easily be cut or demolished with standard equipment.

Typical Applications:

• Segmentss to be removed to create fire protection niches;
• Realization of bypass openings to access the adjacent tunnel or to realize escape routs or venting tunnels;
• Tunnel widening;
• Full crosswalks for Metro Stations;
• Inferior segments for TBM “free” advancement

ATP is now capable to produce special Arched stirrups RWB-Skelt, so making it possible to realize new applications, once not available for GRP composites

ATP is capable to supply at no charge for Design Engineers and for Clients sufficient support for preliminary dimensioning for the mentioned applications.
