In general, roads are trains that are sequentially transmitted to trains, rails, sleepers, gravel, and roadbeds, so that the train loads are fixed to the proper position without moving the sleepers. It refers to the foundation floor used in railways to play the role of to make, to serve as a material for repair in case of sag due to train load or deformation. It is divided into gravel and concrete.

In other words, the gravel ballast (gravel ballast) refers to the image using the gravel as a component of the track structure that serves to distribute the load transmitted from the sleeper of the rail to the roadbed and to secure the sleeper in a predetermined position. Gravel statues are relatively reasonable and economically superior in supporting vibration entrainment and heavy vehicles by high-speed driving of trains, and the construction cost is cheaper than concrete statues, so they are used in general railways. However, when gravel is lost on the railroad, in order to replenish the gravel, the conventional work was performed to replenish gravel at night time when trains do not operate by using a wagon.

Therefore, in order to repair gravel in the prior art, if the gravel is placed on the wagon and the gravel is transported in the drawing position, the equipment for the ballast regulator (ballast regulator) drives the gravel in many places on the standard drawing evenly while driving the gravel.
