Abstract: A modular tunnel forming apparatus includes at least two modules which are arranged one behind the other in the longitudinal direction of the tunnel formwork device and are detachably connectable to one another. The at least two modules each have a frame part, and the frame parts of the interconnected modules form a frame of the tunnel formwork device. At least two support structures, which can be connected to the frame of the tunnel formwork device and are spaced apart from one another in the longitudinal direction of the tunnel formwork arrangement, are provided for supporting the frame on a tunnel floor. The frame carries at least two support cylinders at at least two positions spaced apart from one another in the longitudinal direction, which support cylinders can be connected to longitudinal beams extending in the longitudinal direction, which longitudinal beams carry tunnel formwork elements of the tunnel formwork device.

Abstract: A tunnel formwork device includes a frame and at least two support structures connectable to the frame of the tunnel formwork device and spaced apart from each other in the longitudinal direction of the tunnel formwork device for supporting the frame on a tunnel floor. The frame carries at least two hydraulic support cylinders at at least two positions spaced apart from one another in the longitudinal direction, which support cylinders can be connected to longitudinal beams running in the longitudinal direction. The longitudinal beams carry tunnel formwork elements of the tunnel formwork apparatus. At least one lifting device is arranged on the frame, which lifting device carries at least one working platform. The lifting device has a lifting drive for moving the working platform relative to the frame.
