Importance Of Railway Track Maintenance

Railway transportation is the main force of China's transportation. In its long-term operation, it bears repeated heavy pressure due to natural conditions and the power of trains and vehicles, and bears great responsibilities, including coal outward transportation, goods, transportation, passenger transportation, workers' commuting and other tasks; Especially during the holidays and Spring Festival transportation, the heavy task of transporting passengers can be said to be shouldered by one shoulder, which reflects the dependence of China's transportation on railway transportation.

With the rapid development of China's economy, as one of the pillar industries of the national economy, railway construction is also developing in full swing. The key function of the track is to provide a stable and comfortable operating environment for the train, so the balance of the track itself is directly related to the running safety of the train. If there is a problem because of the track, it will not only cause the consequences of interruption of railway transportation, but also bring the tragic outcome of vehicle destruction and human death, and cause immeasurable impact and loss to the country and society. Therefore, timely repair and maintenance of railway track is an important premise to ensure the stability of track. The safe operation of the train is inseparable from the serious responsibility of the driver, but also from the safe and stable railway track. It has many points, long line and wide range. The track bed and subgrade are often deformed, and the line equipment is also worn to a certain extent. It is difficult to carry out safety management. In order to ensure the safety of the railway track, we not only need to strengthen the management, but also need to repair and maintain the railway track, To ensure the safety of train operation.

Railway is an important national infrastructure, the main artery of the national economy and one of the frequently used means of transportation. It plays an irreplaceable role in China's economic and social development. In the process of train operation, safety is the first priority, and the premise of operation safety is the safety of the track due to the train. Therefore, the safety of the track has become an eternal topic of railway operation safety.

The railway track works in the exposed natural environment for a long time and suffers the erosion of wind, frost, rain and snow. Coupled with the dynamic action of train vehicles, the overload workload of its line equipment with the increase of operation time leads to rail wear, subgrade deformation, track bed hardening, sleeper damage and track geometric size change. Therefore, it must be subject to periodic major, medium or emergency maintenance and planned maintenance in the process of daily operation.

During the operation of the train, the damage to the track structure and its parts is very large, resulting in serious railway line deformation. At present, the common railway track damage mainly includes curve deformation, damage to rail and joint connecting parts, line crawling and so on. In order to ensure the quality of train track and the integrity of equipment, improve work efficiency, prolong the service life of railway track, reduce the incidence of faults, and protect the property and life safety of the state and people, we must do a good job in the maintenance of railway track. For the maintenance of track, the method of prevention in the first place, focusing on prevention and combining prevention and control, and the principle of paying equal attention to maintenance and maintenance should be adopted.
