Why Are They Throwing Salt On Railway Lines

1 Why does the line need to eat salt?

more rain in summer

High water content of roadbed

in winter

Moisture freezes as temperatures plummet

The line is easy to bulge and cause frost damage

cause track irregularities

Affect passenger ride comfort
Injecting salt into the track bed is

Take advantage of the property that the freezing point of salt solution is lower than that of water

In summer, in the track bed with high water content

Add industrial salt

When the temperature drops below zero degrees Celsius

It can eliminate or alleviate the freezing damage of the line

2 How much salt should a line eat at a time?

Salting the wires is no easy feat

There are clear requirements for the amount of salt injection

Operators need to advance

According to the frost damage height of the line

factors such as length and depth

Determine where to dig and sprinkle salt

Excavation depth, calculation of salt spraying amount

3How many steps to add salt to the line?

The first step is to dig a trench

After determining the location of frost damage

Cut the track bed sleeper box into a "V"-shaped groove

The depth of the groove from the sleeper surface shall not be less than 100mm

The second step is to inject salt

Inject a certain amount of industrial salt into the dug trench

to accelerate dissolution

Industrial salt can be crushed first

Water can also be added to promote

Step 3 backfill

Ballast needs to be backfilled in time after salt injection

Tamp the roadbed according to the standard

Keep track bed stable and full
