Beam end ballast blocking and sleeper system integrated device

Abstract

The invention discloses a beam end ballast blocking and sleeper system integrated device, which comprises a reinforced concrete sleeper, wherein side edge blocking components are arranged at the two ends of the sleeper respectively and jointly form a ballast blocking wall, and the sleeper and the side edge blocking components are connected to the end of a bridge through first connecting pieces. Byapplying the beam end ballast blocking and sleeper system integrated device, a ballast blocking effect can be achieved, the effect of a sleeper can also be achieved, and the sleeper and the side edgeblocking components can be directly constructed and arranged at the end of the bridge at the same time. The integrated device is convenient in construction, effectively seals the end of the bridge, prevents railway ballasts on the bridge from falling off, and can solve the problem that the distance between fasteners does not meet the standard requirement after the ballast blocking wall is arranged at the beam end. The integrated device is simple in structure, convenient to use, small in sudden change of the track structure rigidity during application and good in effect.

Description

Technical field [0001] The invention relates to the field of rail transit, in particular to an integrated device for beam-end ballast and sleeper systems. Background technique [0002] With the widespread application of long-span bridges in railway engineering, the disadvantages of traditional ballasted track design methods in the joints of long-span bridges have begun to appear. Due to the large expansion and contraction displacement of the beam at the end of the long-span bridge, the expansion of the bridge and the braking of the train will drive the displacement of the track structure to squeeze the ballast, resulting in the accumulation of ballast in the track structure at the beam end, the empty sleeper and the upper arch of the rail row Such phenomena affect driving safety. [0003] In order to avoid this kind of phenomenon, it is generally necessary to install ballast walls on both sides of the beam ends of long-span bridges. However, after the ballast walls are installed, ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to: aim at the structure of ballast retaining walls and steel sleepers on both sides of the long-span bridge girder end in the prior art, the construction of the steel sleepers is relatively difficult, the vibration is relatively large after opening to traffic, the rigidity of the track structure suddenly changes significantly, and the effect is insufficient. To solve the best problem, provide an integrated device for beam end ballast and sleeper system
