Description
Technical Field

Background
Turnouts are important devices for realizing rail conversion and widely exist on railway lines. The main function of the switch tie applied to the railway switch is to bear the pressure from the steel rail in all directions and uniformly transmit the pressure to the track bed, maintain the geometric shape and position of the track and provide the fulcrum for the switch machine to pull the switch. The ties should have the necessary robustness, resilience and durability, and be capable of facilitating the securement of the rails, and have the ability to resist longitudinal and lateral displacement.
Wooden switch ties are the earliest switch ties in world railways. The main advantages are good elasticity, simple shape, easy processing, light weight, convenient replacement, fast laying and good train impact effect. But at the same time, the sleeper has the defects of high manufacturing cost, short service life, frequent replacement, consumption of a large amount of high-quality wood, environmental damage, easy corrosion, easy abrasion, difficult maintenance of geometric shape and position, easy damage, poor material uniformity, incomplete and consistent strength and elasticity and the like, so the sleeper is rarely used as the sleeper material at present.
The concrete switch tie is the main switch tie form adopted in the world at present. With the requirement of high-speed and heavy-load development of railways, concrete switch ties instead of wooden switch ties have become the development direction of switch ties. The concrete sleeper is simple to manufacture, can ensure the geometric dimension, ensures the rail to have uniform elasticity, improves the stability of the rail, is not influenced by climate, decay, worm damage and fire, and has long service life.

(3) The track bed resistance is small. The steel surface is smooth, the friction coefficient of a contact medium is small, the transverse resistance of a track bed is reduced, and accidents similar to those of an expansion track are easy to happen.
