Introduction to the fixing form of rails

1. Spike fixation
A spike is a metal nail used to fix rails. It is a commonly used fixation method. It is mainly used to nail rails to wooden or concrete sleepers. It needs to be fixed with a hammer and pliers. This fixation method is mainly suitable for new tracks laid by railway bureaus.

2. Clamp fixation
Clamp fixation is mainly divided into three types: V-shaped clamp, elastic V-shaped clamp and thickened plate clamp. The advantage of clamp fixation is that it is more stable, but it requires higher technical requirements and processes.

3. Clip raft fixation
Clip raft fixation mainly combines the clip steel raft plate with the roadbed as a whole to fix the rails. This fixation method is suitable for high-speed railways such as high-speed railways and intercity railways.

4. Prestressed concrete roadbed fixation
Prestressed concrete roadbed fixation mainly improves the stability and safety of the rails by dividing the roadbed into multiple parts and prestressing them separately.

5. Elastic pad fixation
Elastic pad fixation is to fix the pad between the rail and the ballast. The pad can play a role of buffering and balancing, making the railway more stable and stable.

In summary, the main forms of rail fixation include spike fixation, clamp fixation, clip raft fixation, prestressed concrete ballast bed fixation and elastic pad fixation. Different fixation forms are suitable for different railway types and process requirements, so in the construction of railway facilities, it is necessary to choose the appropriate rail fixation form according to the actual situation.
