composite tie的意思|示意

Composite tie, also known as composite rail tie, is an important part of railway track and bridge engineering. It is made up of a steel beam core and a reinforced concrete cover with a certain thickness on the surface.

1. Used for turnout: In the construction of railway turnout, composite ties are widely used. Due to its strong bearing capacity, strong rail anchorage and wear resistance, it can provide a good foundation for the turnout design.

2. Used as a bridge deck: Composite ties also play an important role in the construction of railway bridges. It is made of high-strength material, which has good anti-corrosion, anti-skid and anti-slip performance. It is a safe and reliable bridge deck.

3. Used for railway bed: Composite ties are often used as the foundation for the railway bed. The pressure bearing characteristics of the composite ties are superior to the traditional wooden ties. It prevents track deformation and maintains the stability of the railway.

4. Used for other engineering: Composite ties can also be used as foundation for roadbed, airfield and various other engineering projects. It not only has strong bearing capacity, but is also resistant to deformation, corrosion and high temperature.

In conclusion, composite tie is an important part of railway track and bridge engineering. It has superior bearing capacity and corrosion resistanceto ensure the stability and safety of railway construction. With the development of railway construction, composite ties will play an increasingly important role in railway engineering.
