BRIEF DESCRIPTION OF THE DRAWINGS FIG.

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.

As shown in FIG. 1, the ice layer 3 scatters ice blocks around the cooling pipes 2, passes a cooling medium through the cooling pipes 2, and sprays 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.

As described above, according to the artificial ski resort A of the second embodiment, the core substrate 12 is placed, water is sprinkled on the core substrate 12 to absorb moisture, and the freezing temperature Since the ice layer 3 can be formed by freezing by cooling below, water can not flow even on the slope 7 of the base portion 8 and the work can be easily performed.
By this, the transfer of heat from the base part 8 can be cut off,
When the artificial skiing area A is dismantled, the core base material 12 is merely placed on the waterproof sheet 5, so that the core base material 12
Can be easily removed, and the core substrate 12 can be reused.

[0021]

Since the present invention is configured as described above, the following effects can be obtained. Claims 1 and 3
According to the artificial skiing area and the method for manufacturing the same, the artificial turf is laid directly on the ice layer and frost is generated by spraying water or mist on the surface of the artificial turf, so that the structure is simple. Nevertheless, the artificial turf flock and the frost can give the impression of a real ski resort. Moreover, the artificial turf is laid directly on the ice layer, preventing frost from lingering.

According to the artificial ski resort of claim 2 and claim 4, and a method of manufacturing the artificial ski resort, a core substrate of a soft synthetic resin foam is placed on a laying member, and the core substrate absorbs moisture. Since the ice layer can be formed by freezing by cooling to below the freezing temperature, water can not flow even on the slope of the foundation, making it easy to carry out the construction. It is possible to block the transfer of heat from the part, and when dismantling the artificial ski resort, the core substrate is simply placed on the laying member, so the core substrate can be easily removed, It is also possible to reuse the core substrate.
