A behind a tunneling machine with a trailing shield (1) can be used shuttering for a tunnel lining with in-situ concrete is composed of an inner shuttering (2) and a front shuttering (3). The inner shuttering (2) is divided into several independently movable formwork elements (4 or 5) was dissolved with interposed joints overlappings. 6 Arranged between the trailing shield 1 and the inner formwork 2 front shuttering 3 is advanceable through the in-situ concrete, the pressed into the space formed by the follower shield 1 and mountains, and the inner formwork 2 and the front shuttering 3 annular space. 7 In constructive and functional point of proper conditions result when the inner formwork 2 for successively advancing each of at least one of the shuttering elements (4 and 5) relative to the other, remaining at rest or held shuttering elements (4 or 5) in the tunnel longitudinal direction is set up.
