Treatment for Heavy Injury or Broken Seamless Line Rail (Welded Seam)
May 26, 2023| 1、Rail (welded) heavy injury treatment
(1) Rail material injury and welding seam heavy injury should be promptly cut off re-welding or use adhesive splint reinforcement, and in a suitable temperature in time for permanent treatment; in the implementation of permanent treatment before the inspection should be strengthened, periodic flaw detection, daily inspection found adhesive state bad or injury development in time down the road.
(2) Crack and serious injuries of the rail head, should be in accordance with the rail break for emergency treatment, temporary treatment or permanent treatment.
(3) Other serious injuries can be taken to repair or welding methods to deal with, before processing can be based on the actual situation on site to take speed limit measures.
2. Special parts of the turnout (pointed rail, movable heart rail, wing rail, basic rail, etc.) serious injury treatment
(1) Cracks and serious injuries that may cause the rail head to be uncovered, according to the rail breakage for emergency treatment, temporary treatment or permanent treatment.
(2) Other serious injuries should be dealt with within 24 hours. Injury damage position with reinforcement conditions can be reinforced; if no reinforcement conditions, we should immediately notify the electrical service with, quickly organize replacement for the same type of rail parts, re-tighten fasteners and connecting parts, according to normal speed release train, not welding repair shall not exceed 160km / h.
(3) Treatment before the site in charge of the specific circumstances to take speed limit measures, and arrange special guards, guards should be in each through a train after the damage to the premises for inspection and record, until the damage to the rail properly handled after the guards can be withdrawn, guards such as inspection found damage to the premises may endanger the safety of traffic should immediately take further speed reduction until the blockade measures to ensure safety.
3、Rail (welded seam) breakage treatment
According to the ballast lot and the overall bed lot equipment characteristics are prepared in accordance with the emergency disposal tools. The treatment of broken rails (welded seam) is found to be in accordance with the "Safety Rules for General Railway Engineering", and the broken rails in the high slope section of the Baocheng Line are in accordance with the "Safety Management Measures for Engineering High Slope Traffic".
4、Turnout (regulator) in the rail breakage emergency treatment
(1) If broken seam is located in the tip of the rail and the basic rail, movable heart rail and wing rail outside the scope of the close section, or turnout rail protection outside the scope of the rail, and can be reinforced, treatment is the same as stated above.
(2) When break is located in the tip rail and basic rail, movable heart rail and wing rail close range can not be reinforced or break is located in the tip rail and basic rail, movable heart rail and wing rail close range, and one of the straight strand or curved strand can release the train alone, according to the actual situation on site, confirm the turnout open direction, engineering services tighten, electrical services to confirm the tip rail and heart rail close state, turnout using the console single lock, speed limit release train, and send someone The straight and curved stocks can't release trains or the rail is broken within the range of turnout guard, should be replaced.
5. If shaped rail transition section is broken or transition section outside the broken and can not be reinforced processing, should be replaced.
