Steel sleeper suitable for large-gradient rail and arrangement structure thereof

Abstract

The invention relates to a steel sleeper, and in particular relates to a steel sleeper suitable for a large-gradient rail and an arrangement structure thereof. The steel sleeper comprises a first steel sleeper body, the first steel sleeper body comprises a top steel plate used for supporting a steel rail, a bottom steel plate used for being supported on the surface of a ballast bed and a middle steel plate used for connecting the top steel plate and the bottom steel plate, bent sections extending downwards are arranged on the edge of the bottom steel plate, and first road holding grooves capable of wrapping the surface of ballast are formed between the bent sections. According to the invention, the edge of the bottom steel plate extends downwards to form the bent sections; the first road holding grooves are formed between the bent sections; in practical use process, the bent sections can be inserted into railway ballast of the ballast bed, so that the first road holding grooves wrap the railway ballast, the railway ballast and the bent sections are mutually restrained, the road holding capacity of the bottom steel plate can be effectively improved, the longitudinal and transverse stability is good, a ballast bed connector is simple, the steel sleeper can be suitable for ballasted track sections with different large gradients, and the adverse risk of ballasted tracks can be effectively reduced.

Description

technical field [0001] The present disclosure relates to a steel sleeper, and in particular to a steel sleeper suitable for a large-slope track and an arrangement structure thereof. Background technique [0002] In recent years, the focus of domestic railway construction has gradually shifted to the southwest region. Some of the lines under construction are located at high altitudes and steep slopes. Compared with lines in other domestic regions, their notable features are longer slopes, larger slopes, Axle weight is higher. [0003] As a traditional structural form with strong adjustment ability, ballasted track is widely used in these lines. When it is superimposed on a large slope section, it is inevitable that there will be problems such as poor longitudinal stability of the ballast bed, easy slipping and flow of ballast, and difficulty in maintaining the geometric shape of the track. The sleeper is an important part of the track structure, and it is the main factor th...

Problems solved by technology

When it is superimposed on a large slope section, it is inevitable that the longitudinal stability of the ballast bed is poor, the ballast is easy to slip and flow, and it is difficult to maintain the geometric shape of the track.

The sleeper is an important part of the track structure, and it is the main factor that provides the vertical and horizontal resistance of the line. The
