Rail transit has long operating hours, high traffic density, and poor maintenance conditions. The railway fastening system must have sufficient strength and durability to ensure driving safety.
2) Have certain railway gauge and level adjustment performance
Railway rail transit mostly adopts a monolithic track bed structure, the line curve radius is small, and the steel rail is worn. This requires that the fastening system should have a certain gauge and level adjustment performance in order to solve the problem of curve steel rail abrasion, uneven settlement of the structure and construction errors caused by gauge and steel rail level overruns.
3) Good insulation performance
Rail transit generally uses running rails as return rails, which requires that the railway fastening system must have good insulation properties to prevent current leakage through the fasteners, resulting in electrical corrosion of structural steel bars and municipal pipelines.
4) Have good damping elasticity
Urban rail transit, such as the subway, runs through residential areas, and has high requirements for vibration and noise reduction. The rail fastening system must have good vibration reduction performance, attenuate track vibration, and reduce noise transmission.
5) There is a certain general interchangeability
The rail fastening system should be simple, with few parts, with a certain degree of universal interchangeability, low cost, and convenient construction and maintenance.
The above is the introduction of the performance characteristics of the rail fastening system. We found that the use of this rail fastening system is very wide. It is not only used in the construction of railway lines, so you should learn more about the relevant knowledge so that you can use it in the future. Better application at work.
