PROVISION OF GUARD RAILS गार्ड रेलिंग का प्रावधान In this video has been explained, why guard rails are required to provide? Where to provide the guard rails? Function of guard rails? Design and fixing of guard rails? And many more. Why guard rails are required to provide? Guard rails are provided to avoid serious damages either structure or rolling stock if derailment occurs. Where to provide the guard rails? Guard Rails should be provided on Bridges and Tunnels 1) On all girder bridges (including pre-stressed concrete girder bridges without deck slab) whether major or minor, on all major and important ballasted bridges 2) On the adjacent tracks, In case of ROB/FOBs to a column/pier/abutment which is located within a distance of 8m from centre of track. 3) On Tunnels – length of guard rails depend on sectional speed For Speed above 110 kmph (A) Tunnel with Single Track On approach of tunnel: (a) 200 m from portal face outside the tunnel to 25 m inside the tunnel. (B) Tunnel with Double Tracks On approach of tunnel: (a) Outside the tunnel: 200 m from portal face outside the tunnel. (b) Inside Tunnel: Throughout the length of tunnel but excluding locations provided with check rails. Function of guard rails? If any derailment occurs in the section and dragged upto bridge /tunnel, inside dropped wheels are guided by guard rails to prevent serious damages either structure or rolling stock. Since any derailment a wheel set one is fallen inside of the track and other is fallen in outside of the track Design and fixing of guard rails? Design of Guard rails –The arrangement of a guard rail, with the important dimensions is 1) Clearance between guard rail and running rail “a” 250± 50mm 2) Length of guard rail outside ballast wall and maintained to Clearances up to the length is (L1) 1825mm 3) Length of guard rails to be bent so as to be brought together at the middle of the track length is (L2) 4875mm 4) The top table of the guardrail should not be lower than that of the running rail, by more than 25 mm. Splaying of Guard rails – 1) In the case of through girder bridges on double lines, the Guard Rails should be splayed on both ends on both lines. 2) In the case of bridges other than through bridges on double lines, the splaying need be done only on the facing direction of the particular line. 3) The ends of Guard Rails should be bent vertically and buried and a block of timber fixed at the end to prevent entanglement of hanging loose couplings.
