Formwork for producing concrete tubbing in a tunnel lining system

Abstract

The invention relates to formwork for producing concrete tubbing (500) for a tunnel lining system, with a concrete tub to receive a volume of concrete required to produce the tubbing and, if necessary, to receive the intended reinforcement for the concrete tubbing (500), wherein the concrete tub has at least one base and walls (14, 15) on the base adapted to the mould, wherein at least one wall is arranged detachably from the base and can be pivoted relative to the base between a closed position and an opened position. According to the invention, the formwork has at least one drive system for pivoting the at least one wall between the open and the closed position and for holding same in the relevant position, and the drive system has at least one actuator for pivoting the at least one wall between the open and the closed position.
