Tamping For Railway Operation
Nov 26, 2021| Why tamping?
Due to the effect of train operation or natural environment, part of the ballast of the track bed is trapped in the subgrade, and the track bed is hardened, causing one or both sides of the rail to sink, forming small pits and triangular pits. The height of the line running section is uneven, affecting the safe operation of the train.
2、 What is tamping?
In order to keep the two rails in the horizontal position, the concave rail surface must be raised to the original height. This work is called track lifting. After the track is lifted, the ballast must be added under the sleeper and tightened. This work is called tamping.
After the track laying of the new railway, in order to make the track surface meet the design elevation and make the track bed meet the due bearing capacity, it is also necessary to lift the track, supplement new ballast and tamp. Tamping operation is line maintenance and medium maintenance. Overhaul is an important work.
