Abstract

The invention refers to a formwork system (1) for lining a tunnel, comprising: a reconfigurable formwork structure (3) and a guiding structure (10) configured to be attached and detached from a fixed part of the tunnel. The formwork system (3) is configured such that: the guiding structure (10) is slidable in the longitudinal direction of the tunnel, supported by the formwork structure (3) in its deployed configuration and when the guiding structure is released, and the formwork structure (3) is slidable in the longitudinal direction of the tunnel supported by the guiding structure (10) when the formwork structure (3) is in its folded configuration and the guiding structure is fixed. The invention also refers to a method for lining a tunnel, using the formwork system previously described. The invention reduces execution time, reduces construction cost and improve safety.

Dependent claims

Formwork system for lining a tunnel, comprising:

a reconfigurable formwork structure that can be configured in a deployed position for lining a tunnel by concrete casting, and in a folded position for its transportation,
a guiding structure configured to be attached and detached from a fixed part of the tunnel,
and wherein the formwork system is configured such that:
the guiding structure is movable in the longitudinal direction of the tunnel, when the formwork structure is operatively installed for lining a tunnel, supported by the formwork structure when the formwork structure is in its deployed configuration and when the guiding structure is released, and
wherein the formwork structure is movable in the longitudinal direction of the tunnel, when the formwork structure is operatively installed for lining a tunnel, supported by the guiding structure when the formwork structure is in its folded configuration and the guiding structure is fixed.
