Building a railway is a big project, whether it takes a long time to build a railway that allows trains to go from one city to another, and that's what's amazing about it. Do you usually take a train and find out why there are small stones on both sides of the railway. What's the effect of these small stones? Here is an analysis for everyone.

In fact, this is not an ordinary small stone, this is granite stone, after manual treatment to become today's small gravel. Because granite stones are relatively strong in hardness and can withstand large-scale mechanical forces, this small stone has a synonymous name on the railway, which is called road ballastless. Therefore, the laying of the railway is to lay small stones first and then use the press to mix the small stones with the ground, so that it will be more solid, the last step is to lay sleeper and track, so that the railway will be formed. When the train passes, these small stones can assist the track sleeper bear the gravity together, the disadvantage is that the track will be displaced, should be regularly checked, found problems timely care.

The small stone action can make the train keep a stable running state, avoid the train when moving violently shake, the small stone can strengthen the railway track drainage function, Rain Water will drain the water to the ground through the small stone gap, The downside is that the water will make the weeds grow faster, so another group of people are required to clear the weeds regularly. Even if it snows in winter, there is no need to worry, as long as the depth of snow is not more than 29 centimeters, then these small stones can also absorb snow water, so the railway cost of small stones is lower than that of cement roads, but the cost of manual maintenance and maintenance is relatively high. Generally speaking, a small stone railway is better than a concrete railway.
