What is rail plastic dowel
The railway plastic dowel, also known as rail plastic sleeve, plastic insert, concrete dowel, or concrete insert. It is a component used for fastening railway tracks. It serves as a counterpart fastener for a sleeper screw spike or anchor bolt, and it is typically pre-embedded into concrete or wooden sleepers. It is used in conjunction with screw spikes, guide plates, and rail clips to fasten the rail tracks, ensuring stability of the railway system.
Rail plastic dowel function
● System Foundation
The rail plastic dowel provides essential support as a foundational element in the railway fastening system, pre-inserted into concrete sleepers.
● Connection Assurance
Crucially ensuring a robust connection, it establishes a strong link with components like concrete sleepers, bolts, or nuts, contributing to overall stability.
● Effective Insulation
Functioning as an insulator, it isolates fastening components from wooden sleepers, preventing unwanted electrical conductivity or interference.
● Line Importance
As a vital part of the railway line, its quality, particularly its strength and fatigue life, significantly impacts overall stability and performance.
● Collaboration and Elasticity
Collaborating with anchor bolts, it securely fastens tie plates to rails and sleepers, achieving a sufficient elastic range through rail clips and reducing maintenance efforts.
Types of rail plastic dowel
Rail plastic dowels are commonly used in SKL-type fastening systems and are generally made of PA66 or HDPE materials, depending on technical requirements. We GNEE can also provide customization based on customer preferences.
