Title
(EN) REINFORCEMENT SYSTEM FOR THE CONCRETE LINING OF THE INNER SHELL OF A TUNNEL CONSTRUCTION
Abstract
(EN)

A self-supporting reinforcement system for the concrete lining of the inner shell of a tunnel construction. At least one object is that of supporting the outer shell or rock wall of a tunnel construction. According to an embodiment of the invention, this is achieved by tension brackets or tension rings, formed from one or more bracket segments made of individual reinforcing steel bars. M-shaped tensioning support bodies having a connecting region to the tension brackets, and support arms for the supporting bracing, establishing the spacing with respect to an outer shell or rock wall, of the bracket and spacers on the tensioning support bodies and between the outer layer and an inner layer of the reinforcement.
