Installation and method for position correction of a track structure capable of being sealed in on a longitudinal concrete strip

摘要

Installation for position correction of a track structure, lying on a longitudinal concrete strip (4) as foundation and formed from transverse concrete sleepers (1) and rails (2) and capable of being sealed in concrete (9) by means of reinforcements - in terms of height by means of rotatable height spindles (6) reaching through each sleeper end to the concrete foundation. Provided as installation for levelling is a levelling and lining machine (12) which is capable of travelling on the rails (2) of the track structure by means of bogies (10) and is equipped with a track-levelling reference system (11) and which is equipped with a height-adjustable track-lifting and lining assembly (14) fitted with drives (13), and also with a screwing assembly (15) arranged after said track-lifting assembly and having height adjustable screwing devices (31, 44) each bearing a screwing tool, and a rotary drive connected to said screwing devices and intended for rotating the height spindles (6). <IMAGE>
