Method for producing a tunnel lining from concrete during tunnelling work, having a tunnelling machine, e.g. a shield tunnelling machine. A tunnel lining made from tunnel formwork elements is used to set up a tunnel lining annulus, which is sealed on the side of the road-driving machine by front formwork, and is sealed at the rear end of the tunnel lining by concrete which has already hardened. At least one feed line is used to pump into the tunnel lining annulus via the front formwork flowable concrete which is heated and hardens in the tunnel lining annulus. Furthermore, after hardening of the concrete the tunnel formwork elements attain an adequate degree of hardness following the progressing tunnelling work. Heat is generated in the feed line in the volumetric elements of the concrete, and the concrete is thereby heated thoroughly before entry into the tunnel lining annulus to a temperature of 40 to 70 DEG C. Devices for carrying out the method are also specified. <IMAGE>
