Classification and usage scenarios of common railway spikes
According to different structures and functions, railway spikes can be divided into ordinary spikes, threaded spikes, spiral spikes, elastic spikes, etc. Ordinary spikes are usually used in wooden sleeper lines. They are fixed by directly driving into wooden sleepers. They are easy to install and low in cost, but have limited pull-out resistance. They are suitable for medium and low-speed lines.
Threaded spikes and spiral spikes are often used in concrete sleepers. They form stronger anchoring force by screwing into the embedded sleeve in the sleeper, which can effectively prevent gauge deviation and are suitable for high-speed or heavy-load railways. As a new product, elastic spikes combine spiral structure with elastic buffering function. They can still maintain stability under high-frequency vibration and complex environment, and gradually become the first choice for high-speed railway lines.
Different types of spikes need to be comprehensively selected in combination with line type, sleeper material, track laying structure and operating speed in actual use.
Understanding the usage scenarios of various types of spikes will help railway engineers choose the most suitable spike solution according to line requirements to ensure the long-term safe operation of the line.
