DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be further described with reference to the illustrated embodiments.

The artificial ski resort A of the first embodiment has an ice layer 3 formed by using a laying member 1 and a cooling pipe 2 as shown in FIG.
It is composed of artificial turf 4.

The laying member 1 comprises a waterproof sheet 5 and a heat insulating roll 6 as shown in FIG. Various materials such as synthetic resin, rubber, and asbestos can be used for the waterproof sheet 5 and the heat insulating roll 6. Then, as shown in FIG. 1, the heat insulating roll 6 and the waterproof sheet 5 of the laying member 1 are laid in this order on the surface of the base portion 8 formed of the ground or concrete, asphalt or the like and having the slope 7.

The cooling pipe 2 is a pipe through which a coolant using brine or the like is passed. The cooling pipe 2 is directly supported on the laying member 1 or hollowly supported (not shown), and a plurality of cooling pipes are arranged in parallel along the slope 7. ing. Specifically, as shown in FIG. 1, the cooling pipe 2 is driven into the base portion 8 by the pile 10 using the mounting plate 9 and fixed. Further, the cooling pipe 2 must be able to withstand the temperature to be cooled of the refrigerant passing through the inside thereof, and further, can withstand expansion and contraction due to a remarkable temperature difference between when the refrigerant flows and when it is not. Must be. For example, a soft tube made of vinyl acetate or polyethylene is preferable, which can be used at -80 ° C in terms of cold resistance.
It has good pressure resistance and chemical resistance, and in particular, is resistant to the calcium chloride solution used for brine.

The ice layer 3 scatters ice blocks around the cooling pipes 2 as shown in FIG. 1 and passes a cooling medium through the cooling pipes 2 to spray water or mist while cooling the ice blocks to a freezing temperature or lower. It was created by this.

The artificial turf 4 is laid on the ice layer 3. Then, water or fog is sprayed on the surface of the artificial turf 4 to generate frost. In addition, in the artificial ski resort A of the example, the artificial turf 4 is laid directly on the cooling pipe 2, but it is also possible to increase the thickness of the ice layer 3 and lay it on the ice layer 3. . In addition, it is also possible to scatter snow on the artificial turf 4 and use it.

Further, a method of manufacturing an artificial ski resort according to the first embodiment will be described with reference to FIG. The method for manufacturing an artificial ski resort includes a method of laying a member 1 on a surface of a base 8 having a slope 7.
A heat insulating roll 6 and a waterproof sheet 5 are laid in this order, and a plurality of cooling pipes 2 are arranged in parallel on the heat insulating roll 6 at a distance, and ice blocks are scattered around the cooling pipes 2. Cooling pipe 2
An ice layer 3 is formed by spraying water or mist while cooling the ice block to a temperature below the freezing temperature by passing a coolant through the inside, and laying artificial turf 4 on the ice layer 3, It is completed by spraying water or fog to generate frost. In particular, even if water or mist is not sprayed on the surface of the artificial turf 4, frost is generated.

As described above, according to the artificial ski resort A of the first embodiment and the method of manufacturing the same, the artificial turf 4 is directly placed on the ice layer 3.
The frost is generated by laying water and spraying water or fog on the surface of the artificial turf 4, so that the imitation of the frost and the frost on the artificial turf 4 can give an actual feeling of a ski resort. . Moreover, since the artificial turf 4 is laid directly on the ice layer 3, frost will not be released for a long time.
Further, by laying the heat insulating roll 6 and the waterproof sheet 5 which are the laying members 1 in order, heat is diffused into the base portion 8,
Melted water is not absorbed.

Next, an artificial ski resort A according to a second embodiment will be described with reference to FIG. The artificial ski resort A of the second embodiment has substantially the same structure as the artificial ski resort A of the first embodiment, but the ice layer 3 is composed of a lower ice layer 3a and an upper ice layer 3b, and the lower ice layer 3a. Puts the sleepers 11 on the waterproof sheet 5 at intervals, and lays a thick sheet-shaped core base material 12 using a soft synthetic resin foam therebetween, on the core base material 12. The cooling pipe 2 is hollow-supported by a support member (not shown), and water is sprayed onto the core substrate 12 to sufficiently absorb moisture and is cooled to a temperature lower than the freezing temperature to freeze and form an ice layer. The ice layer 3b is constructed in the same manner as the ice layer 3 described above.

The core substrate 12 is made of a soft synthetic resin foam, which is a so-called sponge, and is specifically made of a flexible foamed polyurethane foam or the like, and is a member having water retention. In the artificial ski resort A of the second embodiment, the core substrate 12 is used for the entire lower ice layer 3a.
Some of them can be used. In the case where the core substrate 12 absorbs moisture, it is more effective to perform the operation while pressing and deforming the core substrate 12.

Further, an artificial ski resort A according to a third embodiment will be described with reference to FIG. The artificial ski resort A of the third embodiment has substantially the same structure as the artificial ski resort A of the second embodiment, except that the thickness of the upper ice layer 3b is increased and water is crashed on the surface of the ice layer 3. The snow layer 13 is formed by stacking snow or artificial snow.

An artificial ski resort A according to a fourth embodiment will be described with reference to FIG. Artificial skiing area A of the fourth embodiment
Is a further application of the artificial ski area A of the third embodiment, in which a core substrate 12 is used for the entire ice layer.
The ice layer is formed by absorbing water and cooling the ice to below the freezing temperature by the cooling pipe 2 located at the center to freeze the ice.

Finally, a method of manufacturing an artificial ski resort according to a fourth embodiment will be described with reference to FIG. The method for manufacturing an artificial ski resort is as follows. Insulating roll 6 and waterproof sheet 5 as laying member 1 are laid in this order on the surface of base section 8 having slope 7, and a plurality of sleepers 11 are spaced on waterproof sheet 5 at intervals. Is mounted, a plurality of cooling pipes 2 are piped on the sleeper 11, a core base material 12 is mounted around the cooling pipe 2, water is sprinkled on the core base material 12 to absorb moisture, and ice is formed. An ice layer 3 is formed by cooling with a cooling pipe 2 below the temperature, and snow or artificial snow made by crashing ice is laminated on the surface of the ice layer 3 to form a snow layer 13 to manufacture the whole. You can do it.

As described above, according to the artificial ski resort A of the second embodiment to the artificial ski resort A of the fourth embodiment, the core substrate 12 is placed, and water is sprayed on the core substrate 12 to remove water. The ice layer 3 can be formed by freezing by absorbing the water and cooling it to the freezing temperature or lower with the cooling pipe 2, so that water does not flow even on the slope 7 of the foundation 8 so that the construction can be easily performed. After the construction, the heat transfer from the base portion 8 can be blocked by the core base material 12. When the artificial ski resort A is dismantled, the core base material 12 is placed on the waterproof sheet 5. Therefore, the core substrate 12 can be easily removed, and the core substrate 12 can be reused.
