FIELD: construction.SUBSTANCE: invention relates to a barrier structure and may be used on a railway line to provide for safety of working personnel during performance of works. The barrier structure to fence the railway line comprises a barrier. The barrier is supported by supports. Supports in their turn rest against a ballast cushion. These supports are made as capable of connection to the existing rail of the railway line. The connection is done by means of a magnetic force. On free ends the supports are equipped with permanent magnets. Magnets have the same shape that they may be introduced into engagement with the rack journal. Due to considerable length of supports it is possible to apply the considerable torque to magnets, as a result the magnets slide along the journal and may be separated from them. The magnet may consist of many magnets laid onto each other. The magnet is preferably made as capable of slight movement relative to the support, in order to ensure compensation for uneven surface.EFFECT: simplicity and acceleration of the process for structure connection/disconnection to/from the rail, and also universality when using on railway tracks with different types of the under-sleeper cushion.14 cl, 6 dwg |
