Abstract: 1. Method for the continuous laying of a rail (4, 4') on a rigid track made of concrete slabs (1), in particular consisting of precast concrete components, whereby the rail (4, 4') is positioned in a channel (3, 3') of the concrete slab (1) and is then fixed by being cast in channel (3, 3'), characterized in that elastic filler blocks (30) are located alongside of the rail (4, 4') within the channel (3, 3'), in that the rails are adjusted via the filler blocks (30) by means of wedges (31) serving as alignment device within the channel (3, 3') in order to achieve a precise positioning of the line and in that the interval (32) between the filler blocks (30) and the channel sides (34) is filled with a grouting mortar. 2. Method as in the preceding claims characterized in that the rails (4, 4') are fastened with conventional rail fasteners (23). 3. Method as in one or several of the preceding claims, characterized in that the interval (32) between the filler blocks (30) and the channel sides (34) are filled with a grouting mortar made of an expansive cement. 4. Method as in one or several of the preceding claims, characterized in that the channel (3, 3') is cast in with an elastic mass (5). 5. Method as in one or several of the preceding claims, characterized in that the precast concrete slab (1) is covered with poured asphalt (36). 6. Method as in one or several of the preceding claims, characterized in that the region of the alignment device (8) is not cast in but is left open, and in that following the at least partial hardening of the casting mass (5), the alignment device (8) is removed. 7. Method as in one or several of the preceding claims, characterized in that the region of the alignment device (8) is cast in when the latter has been removed from the channel (3, 3'). 8. Method as in one or several of the preceding claims, characterized in that the casting mass (5) hardens so rapidly that the alignment device (8) can be removed even while the rail (4, 4') is being cast in at the next alignment device (8). 9. Method as in one or several of the preceding claims, characterized in that the rail (4, 4') is held by the alignment device (8) from the side of the rail head (22) or of the rail base (20). 10. Method as in one or several of the preceding claims, characterized in that a drainage groove is kept open as the area of the alignment device (8) is cast in. 11. Rigid track consisting of a precast concrete slab (1), in particular a plurality of precast concrete slabs (1), for the continuous laying of a rail (4, 4'), whereby the concrete slab (1) is provided with at least one channel (3, 3') in which the rail (4, 4') is placed, characterized in that elastic filler blocks (30) are installed on the sides of the rails (4, 4'), inside the channel (3, 3'), in that wedges (31) acting as alignment devices act upon the filler blocks (30) in order to obtain a precise positioning of the line and in that the interval (32) between the filler blocks (30) and the channel sides (34) is filled in with a grouting mortar. 12. Rigid track as in one or several of the preceding claims, characterized in that the rails (4, 4') are fastened with conventional rail fasteners (23). 13. Rigid track as in one or several of the preceding claims, characterized in that the interval (32) between the filler blocks (30) and the channel sides (34) are filled with a grouting mortar made of expansive cement. 14. Rigid track as in one or several of the preceding claims, characterized in that the precast concrete slab (1) is covered with poured asphalt. 15. Rigid track as in one or several of the preceding claims, characterized in that the sides (33, 34) of the channel (3, 3') and/or of the filler blocks (30) towards the interval (32) are at an angle relative to the vertical axis of the rail. 16. Rigid track as in one or several of the preceding claims, characterized in that in the area of the wedge (31) the sides (33, 34) of the channel (3, 3') or of the filler blocks (30) towards the interval (32) are essentially parallel to the vertical axis of the rail. 17. Rigid track as in one or several of the preceding claims, characterized in that the filler blocks (30) are made of rubber granulate. 18. Rigid track as in one or several of the preceding claims, characterized in that the rigid track is a slab or a precast frame consisting of longitudinal beams (38) and transverse beams (39). 19. Rigid track as in one or several of the preceding claims, characterized in that the rails (4, 4') are installed on or in the longitudinal beams (38). 20. Rigid track as in one or several of the preceding claims, characterized in that spindles (18) are placed in the longitudinal beams (38). 21. Rigid track as in one or several of the preceding claims, characterized in that the rigid track has an opening (7) in the region of the channel (3, 3') that is essentially at a right angle to the longitudinal direction of the rigid track for the at least temporary reception of an alignment device (8) and/or to constitute a drainage groove. 22. Rigid track as in one or several of the preceding claims, characterized in that the opening (7) in the channel (3, 3') reaches at least as far as the slab surface. 23. Rigid track as in one or several of the preceding claims, characterized in that the opening (7) is continued on the slab surface and extends over the entire width of the slab (1).
