How many layers can rails be stacked?
The foundation of the rail storage platform should be made of concrete foundation beams and meet the load-bearing requirements. When using the rail row method, the foundation under the rail row should be treated to meet the load-bearing requirements. The rail storage area should have a flat ground, good ventilation, smooth drainage, and no water accumulation.
Rails should be stored separately according to brand, model, manufacturer, technical standard, and delivery status, and clearly marked.
Rails should be stacked in a positive direction, arranged neatly, straight, and stable, and rails on the same layer should not be overlapped. One end of the rail should be aligned, and the staggered amount (the maximum distance between the end faces of each rail) should not exceed 200 mm. To ensure storage safety, short-length rails can be aligned according to actual conditions.
The support pad should be made of hard square wood or steel strips, placed vertically with each layer of rails, with a spacing of 5 m ~7.5 m, the upper and lower layers in the same position, and the deviation should not exceed 50 mm.
The storage of 100-meter fixed-length rails should not exceed 15 layers. The number of layers of long welded rails stored in the welding rail base should not exceed 6, and the number of layers of temporary rail storage bases at the construction site should not exceed 10. The number of layers should not exceed 8 if the storage exceeds 6 months. The rails on the storage platform should be welded and laid in time to avoid serious rust. The storage time of the lowest layer of rails that have not been treated with rust prevention should not exceed 6 months.
When rails are stacked upright or inverted, the following requirements should be met:
1) The base and the pads between each layer should be stable.
2) The size of each layer should not be less than the width of the rail bottom.
3) When temporarily stacking on both sides of the line, temporary support and binding measures should be taken.
