More particularly, the present invention relates to an apparatus for automatically restoring an orbital subsidence point that is automatically installed on a rail track to automatically restore a site where subsidence of a rail track has occurred.

Generally, a ballast made of gravel (crushed stones) disperses widely the loads coming from the train through the rail and the sleeper, and when the load is transmitted to the roadbed (the surface supporting the orbit) Absorbs the vibration energy caused by running, and acts to prevent the movement of the sleepers due to the expansion and contraction of the rail due to the left and right movement of the vehicle and the temperature.

However, during the operation of the track, a landing settlement takes place at joints and welds located at every train runway, and periodic work is needed to restore these settlement areas. However, it was difficult to carry out such periodic work when the train was running.

Especially, when the orbit is completely subsided, the restoration work was carried out at night through the inspection process.

In this way, when performing a night work in which a train does not run, it is possible to visually check the orbital subsidence caused by the occurrence of a sleeping tie, so that the work can be performed through periodic inspection. However, It is impossible to check.

Therefore, in addition to the problem that a lot of time is consumed to perform the work, the worker checks the sleepers one by one and confirms the sleepers by using the air balloons.

Therefore, when the settlement occurs, the press-fit wedge is artificially pushed further toward the center of the restored pile, so that the filler that has been filled in the fiber sheath of the restored pile receives the pressing force of the press-in wedge and moves in the center direction and the upward direction of the restored pile. As the cross-sectional area of the pile increases, it expands and restores the settlement.

However, the above-mentioned Japanese Patent Laid-Open No. 10-1222078 only restores the bedrock subsidence, and is not suitable for restoration of the track settlement, and can not be realized.

In addition, as a technical feature for settlement restoration, it is necessary to artificially insert the indentation wedge into the restored pile. In view of the fact that the workforce must be assisted, .
