1.2m Concrete Sleeper Introduction
Concrete sleeper also known as sleepers, but also a railway parts. Only now, the material used is not just wood, so called sleeper more scientific;While the sleeper look drab uniform, it's no small role. Necessary to support rail sleepers, but also to maintain the position of the rail, but also put enormous pressure on the rail pass then passed to the track bed. It must have a certain flexibility and elasticity, not hard, soft, too. After the train, it may be appropriately deformed to cushion pressure, but have as much as possible after the train restitution.
1.2m Concrete Sleeper Features
Long life, high stability, maintenance workload is small, the damage rate and the rejection rate is much lower than the wooden pillow. In CWR on concrete sleepers wooden pillow stability than the average increased by 15 to 20%, therefore, especially suitable for high-speed passenger lines. Such as Japan's Shinkansen high-speed lines in Russia are laying it. Of course, there are disadvantages of reinforced concrete sleepers, in particular a weight ratio of wood pillow greater. For example, the United Kingdom of reinforced concrete sleepers each weighing 285 kg, the United States weighing 280 kilograms, Germany has 230 kg lighter. So, in an unstable roadbed roadbed and Reclamation, etc. should not be used; heaving in the winter there is lots, generally not permitted; transportation of coal and ore in a large number and track bed is extremely dirty lots, best not to use.
1.2m Concrete Sleeper Distance
Sleeper spacing should be based on volume, traffic speed and road conditions determine the type of bed. Spacing is small, the roadbed, track bed, rail and sleeper itself suffered forces are small, but the space is too small, increase the cost of the project, and the impact of the track bed tamping operations. Sleeper spacing is generally 52 to 62 centimeters. China Railway generally laying sleepers per kilometer root of the number displayed indirectly sleeper spacing.
