 In the artificial ski slope with the above structure, the ice layer 4 is formed on the base 1 having the cooling pipe 3 having the cooling means 6 built therein, so that the ice layer 4 is cooled effectively. It is maintained without melting for a long time, and since the artificial snow layer 5 is formed on the ice layer 4, the artificial snow layer 5 is also kept at a low temperature, and the snow condition can be kept in good condition.

In addition, since the ice layer 4 is formed by spraying the liquid on the base 1 cooled by the cooling pipe 3 having the cooling means 6 built therein, the artificial snow is installed at the place where the artificial ski slope is installed. An ice layer can be formed easily and in a short time without carrying ice cubes from other sources, and when the liquid to be sprayed is room temperature water, the ice layer material can be prepared at low cost, and Easy to handle.

Further, when the artificial ski slope slope base in which the cooling pipe 3 is provided on the support 10 standing on the flat panel 2 is used, the cooling pipe 3 is higher than the support 10. The ice layer 4 can be easily formed thicker than when the ice is formed near the panel 2 because the ice is formed near the cooling pipe 3 because the ice is formed in the vicinity of the cooling pipe 3. Further, since the cooling pipe 4 is located at a position close to the upper artificial snow layer 5, the artificial snow layer 5 can be cooled even more effectively.

At this time, the temperature inside the cooling pipe 3 is preferably cooled to −10 ° C. or lower. Next, room temperature water is sprayed on the cooled cooling pipe 3. When the sprayed room temperature water adheres to the cooling pipe 3, it is immediately frozen and an ice layer 4 is formed. By repeating this, the ice layer 4 of 10 to 15 cm can be easily formed in a short time.

Next, an artificial snow layer 5 made of free-flowing artificial snow can be easily formed by crushing the upper layer portion of the thick ice layer 4 thus manufactured by a machine or the like to a certain thickness. Wear.

Further, since the brine 6 is flown through the cooling pipes 3 provided on the base 1, the inside of the cooling pipe 3 is always cooled to −10 ° C. or below, and the surface of the cooling pipe 3 is The ice layer 4 is cooled efficiently. Therefore, the ice layer 4 is maintained without melting for a long time. Therefore, the artificial snow layer 5 located above the ice layer 4 is also maintained at a low temperature for a long time.

If the artificial snow layer 5 melts and the condition deteriorates as it is used, the artificial snow layer 5 is formed by crushing the upper layer portion of the ice layer 4, By crushing the upper layer of the ice layer 4 again, the artificial snow layer 5 can be easily regenerated. Therefore, the slope can be repaired in a short time, and the slope can be maintained easily.
