準備が終了する。In the artificial ski resort of the present embodiment having the above-mentioned structure, when using the artificial ski resort, the indoor temperature is adjusted by the start of business of the ski resort, and the snow machine 3 is placed on the drainage material 2. Artificial snow 4 is sprinkled on. The drainage material 2 is a water-permeable member, but since the artificial snow 4 is in a crystalline state, it is deposited on the surface of the drainage material 2 and covers the surface of the drainage material 2. Then, the operation of the snow machine 3 is stopped when the optimum amount of snow is reached, and the preparation for accepting ski passengers is completed.

る。When skiers enter and descent at the start of business, the surface of the slope is roughened by the spur and the treading pressure, and sorbet-formed poor quality snow is generated. Since such a snow condition is not preferable for comfortable skiing, it is necessary to supply new artificial snow to the surface. Therefore, in order to cover such rough and inferior quality snow, the ski machine 3 spills new artificial snow 4 on the slopes at all times or with the ski passengers evacuating.

A large number of water sprinkling holes are opened in the water sprinkling pipe 5 along its axial direction, and the hot water discharged from the water sprinkling pipe 5 is uniformly impregnated in each part of the drainage material 2 and travels along the inclination thereof to the downstream side as indicated by the arrow. It flows down to the water collecting groove 9. Then, the poor quality snow whose surface is covered with fresh snow is sequentially melted by the heat of the hot water from the portion in contact with the surface of the drainage material 2 below it, and flows into the water collecting groove 9 while merging with the hot water. It is collected on the side of the storage tank 10.
