How many spikes are used for track laying per kilometer? Simple calculation of track installation quantity
During the laying process of railway tracks, as an important part of the fastener system, accurate calculation of the number of railway spikes is of practical significance for material procurement, construction organization and budget control. The number of spikes used varies according to different laying methods and track gauges.
Taking the standard 1435mm track gauge and 25 meters of each rail as an example, usually two spikes are fixed to each sleeper (one on each side). If about 1.67 sleepers are laid per meter, about 1.67 × 2 × 1000 = 3340 spikes are required per kilometer (single side), and about 6680 spikes are required for both sides. If a spring clip fastener system is used, the number of related accessories (such as buckle plates, bolts, etc.) should also be matched synchronously.
In addition, if a spiral spike or spring clip spike system is used, the number of auxiliary accessories such as sleeves and washers must also be considered. In actual procurement, it is usually recommended to prepare materials at 105% of the total demand to cope with transportation losses, on-site loss or later maintenance and replacement needs.
Mastering the calculation method of the number of nails used for track laying not only helps to reasonably plan material reserves, but also reduces the risk of construction delays caused by material shortages. It is one of the basic knowledge in railway engineering management.
