ABSTRACT:
Present in a tail shield (1) for a shield tunneling apparatus are a number of grouting lines (3) that are open to a tail shield end (4) and that can be supplied with filling material for grouting a ring gap (7) with the filling material, such as mortar, for example. In addition, additive material lines (8) that can be supplied with additive material are present, which empty into the grouting lines (3) in an end segment (12) of said grouting lines (3). As a result, an additive material, such as a solidification accelerator, for example, can be added immediately before the mixture is discharged into the ring gap (7), so that the risk of a blockage in the grouting lines (3), which are not accessible in the region of the tail shield end (4), is relatively low.
