Analysis Of The Fixing Methods Of Railway Rails

1. Traditional spike anchoring technology

Special metal spikes are used to penetrate the bottom of the rails and fix the rail body directly to wooden or concrete sleepers. This technology is easy to operate and low in cost, but it needs to be installed with special hammer tools. It is common in new sections of ordinary freight lines and low-speed railways.

2. Clamping device fixing system

According to the principle of mechanics, it can be divided into three categories: V-type clamps, elastic clamping modules and thickened plate clamps. This type of system achieves rail positioning through multi-point pressure distribution, has higher stability, but requires precise calibration of clamping force and installation angle, and is mostly used in passenger and freight mixed mainline railways.

3. Raft buckle integration solution

The rail body and concrete roadbed are connected as an integral structure using steel buckle components. This solution can significantly reduce the transmission of track vibration, and is particularly suitable for high-speed railways and intercity rail transit projects with speeds of more than 200 kilometers per hour.

4. Prestressed roadbed reinforcement technology

By prefabricating concrete roadbed blocks and applying prestressed loads, a fixed base with anti-deformation ability is formed. This technology greatly improves the seismic performance of the track system and is widely used in important railway trunk lines with complex geological conditions.

5. Elastic buffer fixing system

Install composite material pads between the rails and the roadbed to absorb impact energy using the elastic deformation characteristics of the material. This solution can effectively improve the smoothness of trains when passing through, and is mainly used in station hubs and curved sections of urban rail transit.

The selection of various fixing technologies needs to comprehensively consider factors such as line grade, design speed, geological conditions and budget cost. In actual engineering, it is usually necessary to adopt a combined fixing solution based on the results of technical evaluation to meet the needs of specific scenarios.
