Problems solved by technology

At present, the existing artificial skiing field technology, one is composed of plastic skiing grass, on which the skis slide. This kind of artificial skiing field has high sliding resistance, which is far from the physical and chemical properties of natural skiing fields; the other is Artificial ski resorts made artificially with water consume a lot of water and are expensive, and can only be used when the temperature is below 0°C, otherwise they will melt
In addition, some people use silica gel as an artificial snow field. This kind of artificial snow will expand when it sees water, and it is basically unusable.

Embodiment 1

[0022] On the plane where concrete is used as the base layer 1, the elastic spongy polyurethane is bonded on the concrete plane with an adhesive to form an elastic layer 2. After drying, the high-strength hot-melt polyurethane is made of a layer with a height of 20 mm. The bottom plate of the columnar molded body with a diameter of 4 mm and a column distance of 5 mm is bonded to the elastic layer 2 to form a skeleton 3. Between the columns of the skeleton 3, a mixture of polyethylene and polypropylene plastics is inserted vertically at a ratio of 1:1. The formed snow-retaining stable fiber 4, the lower part of the fiber is bound on the perforated skeleton 3 bottom plate, and the artificial snow with a particle size of 1 mm made of polyethylene plus paraffin is sprinkled on the snow-preserving stabilizer supported by the skeleton 3. On the fiber layer 4, the surface layer of the ski resort is formed, which can be used by people as a ski resort.

Embodiment 2

[0024] Use polyvinyl chloride board as the base layer 1, fix the foamed PVC to form the elastic layer 2 by means of binding on the base layer 1, and then bond the skeleton base plate with a columnar molded body made of polyurethane to the elastic layer 2 Become skeleton 3 on top, and its cylinder height is 50 millimeters, and diameter is 8 millimeters and column distance is 15 millimeters, then vertically inserts the snow-preserving stable fiber 4 that is made of polyethylene between the columns of skeleton 3, and the bottom of its fiber binds On the perforated frame 3 bottom plate, the artificial snow made by the mixture of polyurethane and calcium stearate with a particle size of 2 mm is sprinkled on the snow-retaining stable fiber layer 4 supported by the frame 3 to form a snow-preserving stable fiber layer for people. As a surface layer for ski resorts.

[0025] like figure 2 As shown, the artificial ski ground of the present invention is made of the base layer 1, the el...

Embodiment 3

[0027] On the plane where concrete is used as the base layer 1, an elastic spongy polyurethane is bonded on the base layer 1 with an adhesive to form an elastic layer 2. After drying, polyethylene and polypropylene are mixed in a ratio of 1:1. The snow-preserving stable fiber 4 made by mixing is vertically fixed on the elastic layer 2 by hot melting, and the density of its fiber is like grass, and then sprinkled on the fiber layer 4 with a particle size of 0.2 mm. Paraffin-waxed polypropylene artificial snow, which forms the surface of the ski area.

[0028] In the above-mentioned embodiments, if the base layer 1 is made of concrete or asphalt concrete, it should be implemented on site. If other materials are used, it can be fabricated and assembled in the workshop in advance, and then laid on site.

Abstract

This invention relates to an artificial skiing field made of multi-layers material, comprising a basic layer, an elastic layer on the basic one, a frame on the elastic one, snow-fixing fibrous layer on the frame and artificial snow layer, every layer being adhered, bound, heat-welded or stapled with others, wherein, the frame stands as cylinder state, snow-fixing layer is fixed in frame vertically. The invention has good sliding quality extremely similar to natural skiing field, so it is deserving wide application.

Description

technical field [0001] The invention relates to a sports entertainment facility made of multi-layer materials, in particular to an artificial ski field. Background technique [0002] In recent years, with the development of winter ice and snow sports, many natural ski resorts have been built all over the world. However, the natural ski resort can only be used by people in cold winter when the temperature is below 0°C. Not only the outdoor temperature limits its use, but also the lack of snow or the small amount of snow will affect the progress of this sport. For this reason, many countries have carried out the research and development of artificial skiing grounds. At present, the existing artificial skiing field technology, one is composed of plastic skiing grass, on which the skis slide. This kind of artificial skiing field has high sliding resistance, which is far from the physical and chemical properties of natural skiing fields; the other is The artificial ski resort m...
