Wide sleeper plate sticking type ballast track

Abstract

The invention relates to a wide sleeper plate sticking type ballast track. After the line foundation of a ballastless track structure of an existing rail transit is deformed, the track repairing work is extremely high in workload, high in time consumption and high in difficulty; a ballast track is easy to repair, but the geometric state of the track is not liable to retain, and the daily maintenance work is high in workload and frequent. The wide sleeper plate sticking type ballast track comprises a railway ballast trough arranged in the line direction and a track structure arranged in the railway ballast, wherein the track structure comprises a macro-molecular material cured railway track, macro-molecular material cured small-granular chicken girt and wide sleeper plates from bottom to top; the macro-molecular material cured railway track is flatly paved at the bottom of the railway track trough; the macro-molecular material cured small-granular chicken girt is located on the macro-molecular material cured railway track; lower grooves are formed in the upper surface of the macro-molecular material cured small-granular chicken girt; the wide sleeper plates are located in the lower grooves. The wide sleeper plate sticking type ballast track has the advantages that the geometric position of the ballast track is liable to retain, the maintenance workload is low in an operation period, and the ballast track can be quickly and conveniently repaired after the foundation is greatly deformed in the space.

Description

technical field [0001] The invention relates to the field of track engineering, in particular to a wide pillow board type bonded ballast track. Background technique [0002] There are two types of railway track systems at home and abroad: ballasted track and ballastless track. Ballasted track, or adjustable frame slab and trapezoidal sleeper are usually adopted for track projects whose foundation is not stable and need to be repaired quickly after damage. (longitudinal sleeper) and other ballastless track structures, the specific characteristics are as follows: [0003] The ballasted track scheme is adopted, which is easy to repair quickly. Under normal operating conditions, the geometric shape of the track is not easy to maintain and the maintenance volume is large. Ballast tamping, screen cleaning, and track lifting usually require large-scale mechanical operations. When a ballasted track structure is used in some parts of the line, it is not economical to equip a variety...

AI Technical Summary

Problems solved by technology

Ballast tamping, screen cleaning, and track lifting usually require large-scale mechanical operations. When a ballasted track structure is used in some parts of the line, it is not economical to equip a variety of large-scale maintenance machines, while using small-scale maintenance machines requires a huge amount of maintenance work and takes a long time and poor working environment

On the other hand, it is difficult to maintain the track geometry of the ballasted ballast bed, and the workload of track adjustment during operation is relatively large

At the same time, the surface of the ballasted track bed is uneven, which is not conducive to the daily inspection of maintenance workers and the evacuation of passengers in emergency situations, and cannot meet the requirements of urban rail transit

[0004] Ballastless track schemes such as adjustable frame slabs and trapezoidal sleepers (longitudinal sleepers) are usually used to meet the adjustment of the slow and large vertical deformation of the base. Bosses are used to limit the position. Once a large space deformation occurs, the structure of the frame plate body or the limit structure will be damaged, and the repair time will be long and difficult.

Especially when there is a large longitudinal displacement of the base, it is usually necessary to make a large-scale adjustment in the longitudinal direction to meet the limit requirements of the maximum support spacing of sleepers, which is difficult to meet the needs of rapid and convenient repairs
