Ballasted track and anti-derailing bridge sleeper

Abstract

The invention relates to a ballasted track and an anti-derailing bridge sleeper. The anti-derailing bridge sleeper comprises a sleeper and an anti-derailing structure, both the sleeper and the anti-derailing structure are made of reinforced concrete, and the anti-derailing structure is integrally formed and embedded in the sleeper, so that compared with a traditional steel guard rail, the anti-derailing bridge sleeper has the characteristics that materials taken are low in price, moreover, buckling piece holes do not need to be reserved, and the construction process is simpler, secondly, compared with the traditional steel guard rail, the anti-derailing structure made of the reinforced concrete is larger in size and larger in weight, the mass of the sleeper can be increased, so that the stability of the sleeper is improved, the contact area between the sleeper and ballast is also increased, and the crushing tendency of the ballast is reduced; meanwhile, the longitudinal resistance andthe transverse resistance of the sleeper are increased, and particularly, the transverse resistance of the sleeper is remarkably increased; and in addition, in a long and large ramp and a starting andbraking area, the anti-derailing structure also plays a role in fixing the sleeper spacing, so that sleeper density change is unlikely to occur, and the good state of a line can be kept.

Description

technical field [0001] The invention relates to the technical field of heavy-duty railways, in particular to a ballasted track and an anti-derailment bridge sleeper. Background technique [0002] For heavy-duty railways, the train axle is heavy, and once derailment occurs, the car will be destroyed and people will be killed. Therefore, guard rails are generally installed in bridge and culvert sections, especially in curved bridge and culvert sections. The traditional guard rail is two parallel steel rails added on the inner side of the basic rail to prevent the wheel from falling off the track and help to block the inner side of the rim. However, the traditionally used guard rails have the following disadvantages: (1) The guard rails are made of steel rails, which are expensive; (2) The sleeper has reserved fastening holes, which is complicated in process and high in manufacturing cost; Too many, easy to loose and easy to lose, prone to safety hazards and so on.
