Railroad base plate

Is a component installed between the rail and the sleeper (or concrete base plate), the main role is to provide stable support and buffer, the load generated when the train passes through the uniform transfer to the lower structure layer, while reducing vibration and impact, protect the roadbed and sleeper, improve the train's running smoothness and passenger comfort.

As an important part of railway track structure, its design standard and performance have an important impact on the safety and stability of railway. Therefore, in the design and use process should strictly abide by the relevant standards and norms to ensure that it meets the requirements of use and plays a good role. At the same time, strengthening daily inspection and maintenance work is also an important measure to ensure its long-term stable operation.

Use and maintenance

The rail underplate should be installed in strict accordance with the design requirements and construction specifications to ensure that the connection between it and the rail and the sleeper (or base plate) is firm and reliable.

Installation

Regular inspection and maintenance of the pad, timely detection and treatment of cracks, wear and other problems to ensure its normal performance.

Inspection and maintenance

For the gasket that is seriously damaged or has reached its service life, it should be replaced in time to ensure the safety and stability of the track structure.

Design criteria

Material selection

The rail underplate is generally made of high-quality steel or high-strength alloy materials to ensure its high bearing capacity and durability.

Size and shape

The size and shape should be determined according to the specifications of the rail, the gauge, and the arrangement of the sleeper (or base plate) to ensure a good match and stability with the track structure.

Carrying capacity

It must have sufficient carrying capacity to withstand the huge pressure generated when the train passes through, and ensure the stability and safety of the track structure.

Stability and durability

The design should be reasonable, can effectively disperse the stress between the track and the sleeper (or base plate), and improve the stability of the track.

Shock and noise reduction

It should have good shock absorption and noise reduction performance to reduce the vibration and noise generated when the train passes.

Electrical insulation

When needed, the pad should also have good electrical insulation properties to protect equipment such as signal systems from current interference.
