Prestressed concrete lining in a pressure tunnel

A prestressed concrete lining in a pressure tunnel, with several reinforcement cages (32) distributed around the circumference and along the pressure tunnel and bordering at least partially on each other, with prestressing elements (38, 39, 40, 41), which encompass at least a part of the circumference of the pressure tunnel, with stressing anchorages (42) to stress the prestressing elements, the stressing anchorages being accessible from the inside of the tunnel, and with a bottom part (35) extending along the length of the pressure tunnel, formed of several individual anchorage bodies in series, whose side surfaces are each bordered by reinforcement cages, wherein each of the anchorage bodies (1, 15, 19) has an essentially U-shaped cross section with a pair of extending arms at a distance from each other which are connected with each other at their base by a base arm, wherein each of the extending arms (2,3) of the anchorage bodies turned towards the inside of the tunnel there are a first pass-through means (5,20) for at least one of each of the prestressing elements (38, 39, 40, 41), a bearing plate (8) being disposed on the facing inner surfaces of the arms in the region of each of the first pass-through means (5, 20), and wherein the base arm there are second means (10, 21) for passing through at least one each of the prestressing elements (38, 39, 40, 41), starting from a dead end anchor (43), is fed through one of the second pass-through means (10, 21) of one of the anchorage bodies and, after crossing through one of the first pass-through means (5, 20) of one of the anchorage bodies, ends in an anchor head (48) of a stressing anchorage (42) adjacent to one of the bearing plates (8).
