Ballast Cleaning-An Important Part of Railway Maintenance

2018-10-08 14:19


Rapid economic development, population growth, and accelerated urbanization will stimulate transportation demand, so the potential for railway passenger transportation is great. With the rapid development of railways, railway maintenance machinery has also been continuously upgraded.

The soar development of the railway has made the transportation density of the railway trunk line continue to increase.The busy railway trunks put forward higher requirements for maintenance , and more and more require automation and large-scale maintenance machinery.


This situation has determined that the mechanization of road maintenance will inevitably undergo major changes and move towards a large mechanized development path.The safe operation of railways has promoted the rapid growth of new road maintenance machinery, and road maintenance machinery has continuously improved the operation efficiency and quality.

We must carry out large-scale road maintenance machinery and equipment planning, and increase the introduction of maintenance machinery and equipment such as tamping, cleaning, grinding.

The latest development of large-scale maintenance machinery is to meet the high requirements of maintenance machinery for passenger dedicated lines, speed-increasing lines and heavy-duty lines through independent innovation.

At present, large-scale road maintenance machinery has achieved great development, and the research and development capabilities in the field of maintenance machinery have also been greatly improved.Large and medium-sized road maintenance machinery has been widely used in various busy railway trunk lines, and patented technologies related to maintenance machinery are also increasing.

Ballast cleaning is a key part of railway maintenance operations.As the main project of large-scale construction, ballast cleaning has been focused on solving the problems of muddy mud and road bed knots on the railway line.

When the powder in the ballast bed is broken and the cohesive soil mixed in the ballast during construction, or the soil is brought into the track bed by the wind and water, and the coal ash of the train is mixed with the ballast, the railway bed is unclean.This will fill the gap of the ballast, forming an impervious layer, causing poor drainage, and there will be muddy, which will cause the railwaybed to be knotted, the elasticity will decrease, and the shock absorption effect will be worse. Therefore, the ballast bed should be cleaned.


The construction space of the railway line clearing operation is narrow, the roadway has many roads, the construction cooperation unit is many, and the work conditions are very difficult.When cleaning the ballast, it is necessary to stop the transportation work and close the line.

During the close time, not only must the ballast cleaning work be completed, but the road must be restored to its original state, so the timing is particularly important.

In addition, the construction personnel must ensure the construction quality while ensuring the safety of the construction process. Only in this way can the railway clearing work be truly completed.

In addition to this difficulty, the ballast cleaning operation still has the quality requirements of the construction personnel, the safety inspection of the equipment, etc.
