Now commonly used railroad spikes include the following types: railroad dog spike, screw spike, spring spike. They are used in different ways, but their effects are the same, that is, through the different structure and use methods, to make rails fixed and stable.
Core Advantages of Screw Spikes
Compared to traditional spikes, screw spikes offer the following significant advantages:
(1)Stronger Pull-Out Resistance
The helical grooves increase the contact area with soil or base materials, dispersing pressure under force and preventing loosening due to external pulling. This makes them particularly suitable for soft soil or scenarios requiring long-term stability, such as railway sleeper fixation and fence installation.
(2)Easy Installation
Screw spikes can be installed using specialized tools or common power drills, with some models even allowing direct hammer-driven insertion. Compared to expansion bolts requiring pre-drilling, their construction efficiency is higher, making them ideal for large-scale projects.
(3)Wide Adaptability
Whether in sandy soil, clay, or gravel foundations, screw spikes can adapt by adjusting groove depth and material. They can also be used with base materials such as wood and concrete, offering highly flexible applications.
(4)Eco-Friendly and Durable
Screw spikes are reusable and require no chemical adhesives, reducing environmental pollution. Their anti-corrosion treatments also extend service life and lower maintenance costs.
