A stringer sleeper system

Abstract

The invention relates to a novel sleeper system, and belongs to the field of railway tracks. The novel sleeper system comprises a longitudinal beam type sleeper and an elastic vibration reduction track system, wherein the longitudinal beam type sleeper is formed by connecting longitudinal beam type sleeper units one by one in series; each two adjacent longitudinal beams of the longitudinal beam type sleeper are fixedly connected with each other in the lateral direction through a connecting piece; the opposite longitudinal beam end parts of each two adjacent longitudinal beam type sleeper units are connected with each other through a sleeper connecting piece; the elastic vibration reduction track system comprises a support saddle; the longitudinal beam type sleeper is mounted on the support saddle; and a vibration reduction facility is arranged between the bottom of the longitudinal beam type sleeper and the support saddle. The novel sleeper system has the advantages that due to the longitudinal sleeper, the bending rigidity of a track is enhanced, and deformation of the track caused by repeated load is reduced; as the lateral resistance of the longitudinal beams is enlarged, the irregularity in the vertical direction of the track is reduced, and the maintenance is reduced; and as the longitudinal beams are connected with each other in the longitudinal direction, the settlement of the track at the end parts of the longitudinal beams is provided from being enlarged or damaged easily; and as rail pads are arranged continuously, foundation shake, rolling noise and wave-like deformation of the track are reduced.

Description

technical field

[0001] The invention relates to the field of railway tracks, in particular to a novel sleeper and elastic damping track system in the field of railway tracks. Background technique

[0002] Railway tracks generally include ballast beds (ballasted or ballastless), sleepers and rails. The ballast bed is formed on the roadbed or bridge, the sleeper is laid on the ballast bed, and the steel rail is installed on the sleeper. But no matter what kind of sleepers, most of the railways currently adopt horizontal sleepers, that is, sleepers are laid along the transverse direction of railways or rails. There are many disadvantages and deficiencies in this kind of transverse sleeper: the transverse sleeper is laid discretely on the track bed, so it is not conducive to the distribution of the load from the steel rail. When the train passes, affected by the impact wheel weight, the impact load on the sleeper is very large, which is easy to cause damage to the ballast bed ...
