<p>The invention relates to a method and to a plant for producing tubbing for a tunnel lining, wherein a tubbing shell (4) having a cover arrangement (12) which can be opened, has an underside and comprises an opening is filled with fresh concrete (24) and the tubbing is removed from the tubbing shell (4) after it has solidified. The fact that the tubbing shell (4) is tipped into a compression position at least before solidification, which compression position is selected in such a way that air bubbles (32) which collect below the opening on the underside of the cover arrangement (12) rise to the opening along the underside, achieves a situation where the upper side of the produced tubbing which later faces the tunnel outer side is smoother and/or has less deformations and/or can be produced less expensively than previously.</p> |
