By turning 121, the ground (E) is excavated to form a course groove (D) as shown in FIG.

The operation during this time can be remotely controlled by the controller 4000, and is received by the antenna 2114 to cause the maintenance device 2000 to operate at a rate of, for example, two to three times per minute.
The course groove (D) is sequentially excavated while being propelled at a speed of about m, and at the same time, the electric motor 3010 is started by the antenna 3031 so that the slider 3000 is propelled at the same speed as the maintenance device 2000. It is to let.

Thus, the maintenance device 2000 is moved at a required equidistant position with respect to the guide rail 1100.
As shown in FIG. 9, the course concave groove (D) can be accurately excavated at a predetermined distance (L1), and can form a snow layer course surface (F) described later with a precise predetermined dimension. This will be described later.

The dimensions of the course groove (D) are preferably as follows. ◎ Width: 10m-18m ◎ Total length: 80m-150m ◎ Inner height of the wall: 2m-4m

The height and the direction of the screw conveyor 2122 are changed as needed by 130 to complete the snow course surface (F).

Incidentally, also in this process, the maintenance device 2
000 and the guide rail 1100 are connected by the connecting device 2
Since it is completely regulated by 300, it will be moved along guide rail 1100.

Therefore, since the distance between the screw conveyor 2121 and the guide rail 1100 is not changed, the snow layer course surface (F) is precisely excavated at a predetermined constant distance (L2). It is possible to make 1000 formations.

In addition to the case where the course 1000 is newly formed as described above, the above-mentioned case is also taken when, for example, repairing a course surface damaged by a game or when the course surface is deformed by new snowfall. Similarly, it goes without saying that the snow course surface (F) can be maintained.

Therefore, it is possible to form the snow course surface (F) smoothly and promptly and precisely in accordance with the standard without specially adjusting the running direction of the maintenance device 2000.

Incidentally, the excavated snow may be appropriately removed similarly to the above-mentioned excavation step.
