Shocked： Different ice project venues adopt different ice！
In recent years, winter sports have become more and more popular. Do you think that their venues are all on the same ice surface? That would be wrong. Common ice sports include curling, ice hockey, speed skating, short track speed skating, and figure skating, and the bottom layer and temperature of the venues are different. Let’s learn about the site construction of the ice project today~
Drainage, gravel, heated cement bed, insulation, chilled cement bed with refrigeration pipes, and ice making. First, the ordinary ice layer is sprayed with white paint, then sealed, and the marks of various competitions are painted with colored paint, and then water is added layer by layer, leveled, and polished. Pure water should be used for ice making, the purer the water, the harder the ice.
The temperature of the ice surface of the speed skating venue is low, and the colder and harder ice surface can provide better strength support for the long blade, which is beneficial to increase the speed. Speed skating is divided into short track and main track. The short track speed skating venue requires the thickness of the ice to be 3.5~4.5 cm, and the ice temperature should be controlled at around -5.5°C. The ice surface thickness of the speed skating venue needs to be about 2.5~3 cm, and the ice temperature is -5℃~-9℃. The water spilled from the ice pouring truck that makes ice is boiled water. Boiled water poured on the ice can better integrate with the old ice, and the water has been purified, so it is clean enough to drink. In this way, the quality of the ice track is guaranteed very well. Even when the game is vacant, the ice truck needs to be poured with ice every two hours or so. This is because after about two hours, the ice surface will frost, which is no longer suitable for competition.
Figure skating shared the same venue with speed skating a long time ago, but the ice surface of figure skating should be good for landing. The thicker ice is less likely to be penetrated by the strength of the skates, and the ice temperature is higher and the relatively soft ice is less likely to be crushed by the impact of landing and landing. With the development, the venues for the two sports have also been separated. The thickness of the ice in the figure skating venue is thicker than that of short track speed skating, reaching 4.5~5 cm, and the ice temperature is around -3°C
Curling is on a specific venue, with a slightly lower middle and ice crystal particles on the surface, which is convenient for arcing and increasing friction. The ice on the site should be 5-6 cm thick, the ice temperature should be around -6°C, and the humidity should be less than 50%. Distilled water is used to make ice, and it takes 8 to 10 days. First, a layer of bottom ice must be frozen on the track, and water must be poured evenly on it with a thin water pipe, and then replenished with water and sprayed with white paint. The ice you see The milky white color of the kettle track is actually the color of the paint. After spraying the primer, it is accurately measured, and the base camp, marking lines, etc. are painted with the color paint. Then continue to replenish water and level off. After the flatness meets the requirements, use an ice scraper to repair the arc. In fact, the curling track is not flat, but a slightly concave U-shaped field, so that players can throw the curve ball. After the ice making is over, a layer of tiny ice particles is sprinkled on the surface of the track to ensure that athletes can change the friction of the track by brushing ice. The resulting ice sheet is 5 to 6 centimeters thick. Ice paints of various colors are completely grease-free and fully compatible with water.
The ice surface of ice hockey needs to consider the player’s sharp turn, sudden stop and ice wear, so its nature is between speed skating and figure skating. The thickness of the ice surface on the site is required to be 2-5 cm, and the ice temperature should be kept at around -6°C. The humidity does not exceed 40%. If the humidity is high, the ice surface will be fogged, which will not only affect the sight of the players, but also affect the trajectory of the ice hockey
This is the end of the introduction to the ice sports venues. If you still don’t understand something, you can leave a message~
