Sleepers are an important component of railway track construction for supporting rails, transferring train loads and transmitting the various stresses to which the rails are subjected to the track bed. At present, the study and the use of the sleeper in China are mostly suitable for the railway line with single track gauge. The ties are substantially identical in shape. However, with the continuous development of economy, the research and the use of railways are continuously developed, and the shapes and the lengths of sleepers tend to be diversified according to the use requirements.
Currently, train and sleeper maintenance work mainly relies on manual on-site inspection and maintenance. This approach has two problems:
firstly, the safety of inspection personnel is solved;
and secondly, the effect problem of manual inspection is solved.
When working personnel face repeated mechanical work, tiredness and lacked psychology are easy to generate, the inspection effect and quality are reduced, and due to the fact that sudden and timeliness exist in equipment failures, the purpose of real-time monitoring cannot be met through manual inspection, and disasters often happen instantly. Therefore, the effect of manual inspection is unstable, and the reliability cannot be improved.
The condition that there is a sleeper of multiple gauge sharing in the railway construction, there is the railway line form of a rail of two kinds of gauges sharing in mixed rail railway line, then a rail is the sharing rail, all the other two rails are in different positions because of the difference of gauge, sleeper length also changes according to the change of gauge, when current sleeper design is applied to three-way mixed rail railway, the rail sectional area increases on the sleeper, in the great area of temperature difference, the temperature power that the rail produced is also relatively great, the railway roadbed lateral resistance is not enough, whole track loses stability more easily. In order to ensure the safe and stable running of the train, enough longitudinal and transverse resistance between the sleepers and the track bed should be provided as much as possible, so that the maintenance period of the sleepers is shortened, and the stability of the track frame structure is ensured. The high-resistance sleeper for the three-line mixed rail railway is designed on the basis of the existing sleeper.
