Abstract (en)
[origin: EP0339333A1] In the method or the device for cutting and lining tunnels, shafts or the like of elongated structures, the driving is effected by means of a shield or cutter driving device. Here, the shield tail or the cutter tails (24) at the same time serve as outer formwork for the cast-in-situ lining, i.e. for producing concrete sections (28, 30, 32). In order to prevent the hollow space between the cast-in-situ lining (26) and the soil (12) from being incompletely filled after driving of the cutters, the tail of the shield or cutter driving device is divided into individual parallel strips (24) arranged at a distance from one another and supporting the soil (12), so that the spaces between the strips in the form of ribs are filled with concrete when the cast-in-situ lining (26) is being concreted. After the driving of the shield or the cutters, the spaces between the ribs are filled with concrete. <IMAGE>
