Abstract (en)
[origin: EP2472057A2] The present invention relates to a formwork for concreting the inner lining of tunnels, made up of a resistant structure formed by two polygonal rings, perpendicular to the axis of the tunnel, made up of a variable number of ribs (1) articulated to one another and joined by a telescopic prop (4) which allows varying the angle they form in order to thus vary the curvature of the perimeter ring, such that by also varying the number of ribs (1) it is possible to adapt it to any measurement and configuration of the tunnel (t) to be constructed; a series of secondary ribs (2) externally defining a curvature (21) in accordance with each area or sector of tunnel in which it is assembled; and a series of flexible steel sheets (3) which adopts the radius of curvature suitable for the area or sector of tunnel to be constructed and makes up the skin of the formwork on a surface, having the length of the formwork and the width corresponding to a sector of tunnel, defined by one of the intermediate parts(2) supporting it and by the rib or ribs (1) forming the inner structural rings.
