The cooling layer 11 (trade name: Ice Mat (manufactured by Nomura Kasei Co., Ltd.)) having a pipe of about m as the refrigerant flow pipe 10 can be cited.

The artificial snow used in the present invention may be artificially produced snow or artificial snow mixed with natural snow, and is not particularly limited. Specific examples of the artificial snow used in the present invention include, for example, water absorption by artificial snow or a superabsorbent polymer made by using a snow gun type or a fan type as an artificial snowfall machine, an ice crusher (ICS) or the like. Artificial snow produced by freezing and a mixture of two or more of these can be mentioned.

The ICS can produce snow even at a plus temperature, and the artificial snow made by the ICS can produce a snowy mountain, a snowman, and the like, and thus can be preferably used in the present invention.

The superabsorbent polymer used in the present invention includes starch, cellulose, and synthetic resins such as polymers such as acrylamide, acrylic acid, acrylate, methacrylate, styrene and vinyl ether, copolymers and terpolymers. System.

Some superabsorbent polymers are water-soluble and become paste-like or flake-like, crushed or granular when they absorb water. In the present invention, any of these can be used. . When made into artificial snow by absorbing water and freezing into a superabsorbent polymer selected from these superabsorbent polymers as appropriate, a soft snowy artificial snow, a hard artificial snow,
Soft snow, lumpy snow, icy snow,
Various forms of artificial snow, such as plate-shaped artificial snow and artificial snow in which particles are bonded to each other, can be produced.

As the superabsorbent polymer having a flake shape,
Specifically, an aqueous solution of a monomer containing acrylic acid and an ammonium salt or an alkali metal salt of acrylic acid is added to an aqueous solution of 0.1.
1-10% by weight of a polyvalent organometallic ion crosslinking agent is added to form an aqueous solution, which is then polymerized and dried, and a moderately crosslinked superabsorbent polymer obtained by drying, or an ammonium salt or an alkali metal salt of acrylic acid and acrylic acid. Moderately crosslinked superabsorbent polymer obtained by post-crosslinking a copolymer of the above with 0.1 to 10% by weight of a polyvalent organometallic ion crosslinking agent.

Examples of the superabsorbent polymer showing a crushed or granular form include a method of pulverizing the above superabsorbent polymer and processing it into a predetermined particle shape, and a method of polymerizing or condensing from a raw material compound of the above superabsorbent polymer. Examples include a method of forming a polymer compound in the form of a spherical or granular polyacrylate obtained by reverse-phase suspension polymerization in an organic solvent, a vinyl alcohol-acrylate copolymer or isobutylene. Even if water is absorbed such as a superabsorbent polymer (for example, an average particle size of about 0.005 to 5 mm) obtained by a method of saponifying a copolymer with maleic anhydride, the particles maintain non-tacky properties with each other. Things can be mentioned. For example, if water is absorbed by a superabsorbent polymer that retains non-adhesiveness to each other even when water is absorbed and frozen to form artificial snow, artificial snow in the form of powdered snow can be produced. By making the artificial snow by absorbing water below the water absorption capacity and freezing it, it is possible to make a dry powdery artificial snow with water absorption ability.

As the material for forming the underlayer 12 used in the present invention, ice has the highest heat storage capacity and is the most cost-effective in terms of heat storage capacity, but it is desirable to use it in combination with other materials.

Examples of the material for forming the underlayer 12 include the above-mentioned superabsorbent polymers. The superabsorbent polymer absorbs a large amount of water having a high heat storage amount and maintains the water retention state without disappearing like snow even if the temperature rises, so that the effect is maintained, so that it is preferably used. The superabsorbent polymer has a large ability to absorb a large amount of water, store cold heat, and has a heat insulating property, so that it has a large effect of preventing snow melting when the temperature rises. Further, the superabsorbent polymer can maintain the water retention state even when the temperature rises, and can be continuously maintained as the underlayer 12.

The superabsorbent polymer that can be used as a material for forming the underlayer 12 in the present invention may be any of the known superabsorbent polymers as described above, and the shape of the superabsorbent polymer (granular, flake, etc.) , Amorphous, etc.), the particle size or the state when frozen (snowy to icy to plate-like) are not particularly limited. However, the superabsorbent polymer, in which the particles are non-adhesive to each other in a water-retained state and can maintain independent particles, contains a large amount of air between the particles. Further, in order to reduce the amount of the superabsorbent polymer used from the viewpoint of economy, a superabsorbent polymer having a water absorption capacity of 50 times or more can be preferably used.

However, for example, when a superabsorbent polymer in the form of smooth particles is used, there is a risk that the polymer will scatter when installed on the cooling layer 11 or flow out into the drain 18 when the artificial snow melts. In order to prevent the water-absorbing polymer in the form of particles, the superabsorbent polymer is formed of a material such as a woven fabric, a nonwoven fabric, a net, or a porous sheet having openings so that the superabsorbent polymer does not leak to the outside. For example, sandbags, non-woven bags, porous sheet bags,
It is preferable to place a large number of them on the cooling layer 11 by putting them in a net bag, a net bag, a bale, a sashimi, etc.).

The material of the water-permeable package may be plastics such as polyolefin and polyester, metal such as steel, and natural fibers such as hemp, jute, straw, and cotton. The plastics are lightweight and strong. And it is inexpensive and can be preferably used.

The superabsorbent polymer placed in the water-permeable package does not scatter or flow when laying, using, or collecting. Base layer 1 that can be maintained uniformly and stably by using a water-permeable package containing a superabsorbent polymer inside.
2 can be formed efficiently and simply, and at the time of collection, the water-permeable package containing the superabsorbent polymer therein can be easily collected and reused.

The superabsorbent polymer used in the present invention is used for agricultural purposes as a soil improver, and its safety has been confirmed in various tests, so there is no problem in safety. It is an environmentally friendly material that does not accumulate due to photodegradation or biodegradation.

A method for forming the underlayer 12 using a water-permeable package containing a superabsorbent polymer will be described. A number of water-permeable packages containing a superabsorbent polymer therein are laid on the cooling layer 11 so as to be adjacent to each other, and the water-permeable packages are fixed with, for example, an auxiliary tool, and the spaces between the water-permeable packages are also fixed. Then, water is supplied from the outside to the inside of the water-permeable package by a method such as sprinkling water to make the superabsorbent polymer absorb water, thereby forming the underlayer 12. Instead of water spraying, a water-permeable package in which a superabsorbent polymer is previously absorbed with an appropriate amount of water having a water absorbing capacity or less can be used. Then, artificial snow (ICS,
The artificial snow layer 8 is formed by laying artificial snow or artificial ice by an artificial snowfall machine such as a fan type or a snow gun type. Even if the artificial snow layer 8 melts due to a rise in temperature,
The superabsorbent polymer in the underlayer 12 absorbs the water, and the snow quality of the artificial snow layer 8 is maintained satisfactorily, for example, when the solid snow becomes tight and snow.

Since the present invention is not limited to the above embodiment, various modifications can be made without departing from the spirit of the present invention.
