Concrete Railway Sleepers
Concrete railway sleepers (also known as concrete ties) are sourced from diverse materials, ensuring excellent rail stability. They meet the demands of high-speed and heavy-traffic main railway lines, are resistant to climate, decay, pests, and fire, resulting in a long service life. However, they lack flexibility and may crack, making replacement challenging due to their weight.
Classification of Concrete Railway Sleepers
- Manufacturing Processes: Ordinary and pre-stressed concrete sleepers.
- Reinforcement Sizes: Available with high-strength steel strings or bars.
- Types: Three main types of concrete sleepers are used on various railway tracks.
- Wide Concrete Sleepers: These are designed with a larger base area to support rails better, reducing subsidence and improving stability. Continuous laying minimizes gaps, keeping the track neat and reducing maintenance.
Shape of Concrete Railway Sleepers
Concrete sleepers typically feature a trapezoidal cross-section to enhance bearing area. This design accommodates more steel bars to resist cracking and includes grooves to improve resistance between the sleeper and track bed.
Usage Rules for Concrete Railway Ties
Concrete railway ties should not be used on temporary lines, unstable bases, or curves with a radius under 200m. At railway bridges and turnouts, wooden sleepers should be used as transitional sections to prevent mixing with concrete sleepers.
Damage and Causes of Concrete Railway Sleepers
Common issues include:
- Cracks: Caused by gaps between the sleeper and ballast.
- Knock Injuries: Resulting from poor handling during transportation and installation.
- Shoulder Damage: Due to lateral forces from trains.
- Derailments: Can cause severe damage.
- Fastener Issues: Compromised connections can lead to failures.
Prevention and Treatment Measures
To prevent damage:
- Avoid knocks during transportation and installation.
- Perform track lifting carefully.
- Strengthen tamping efforts beneath the rails.
- Regularly clean the track bed to maintain flexibility.
- Ensure fastener performance to prevent rail movement, making timely adjustments as needed.
