The rotation of the blades z is hindered, the snow cannot be moved, and it becomes impossible to perform the above-described respective conveyances. For this reason,
The maintenance work or construction work of the slope is forced to be interrupted, and the purpose of introducing the above-mentioned A installation type slope maintenance / building device a1 or B installation type slope maintenance / building device a2 is sufficiently achieved. It became impossible to do so. Further, the user who has introduced the device and the manufacturer who has delivered the device perform maintenance work for fixing the above-mentioned malfunction of the screw conveyor and putting the entire device in a smooth operable state again. , Often after installing the device.

For this reason, a large amount of snow must be made so that it can be sprayed on the slopes at any time. However, both the A-installation type slope adjustment / building device a1 and the B-installed slope maintenance / building device a2 described above are provided with a plurality of snow-making devices d concentrated in one place. Then, the snow-made snow is temporarily stored in the snow storage building f, and if necessary, the snow storage building f is stored.
It is designed to be taken out from and sprayed.

It is also essential to install a screw conveyor such as the conveyor h. Due to such an installation mode, the cost of installing the device is inevitably inevitable, the initial investment becomes large, and the spread of the device is hindered.

According to the inventions of claims (1) and (2), it is possible to relocate a device for making snow, and to carry the required amount of snow by a number capable of making snow to build a slope. Disperse and arrange them on the ground or at multiple places beside the slopes that require maintenance. Then, each distributed device is operated individually to disperse and store snow directly under snow making, and then repeat the process of transporting and consolidating the dispersed and snow-stored snow on the ground where the slope is to be constructed or on the slope where maintenance is required. It is designed to disperse and consolidate the required amount of snow and then build or maintain the slopes, which allows the snowmaking process to be directly transferred to the maintenance / building process. .

The amount of snow required for maintenance is distributed to each of the planned construction site or multiple locations close to the maintenance target slope, and individual transportation or individual spraying and consolidation are sequentially repeated, and the skiing is performed. Slopes are constructed on the planned construction site or on the slopes to be maintained at a certain interval by dispersing and consolidating, and then the snow that has been distributed and consolidating is smoothed, or
Due to the slope maintenance / construction method of maintenance, snow-made snow is caused by the pressure snow on the way of transportation, which is caused by the repeated transportation of multiple snow conveyors and other transportation means over long distances. There was no interruption of the snow supply.
