Will the Summer Palace skating rink fall in?

Whether the Summer Palace skating rink will fall in depends on the thickness of ice and other related factors. There is a certain safety factor for setting up an open area for the staff, and they need to obey the command of the staff and cannot do dangerous things. According to the analysis of the bearing capacity of the ice layer, when the thickness of the ice layer is ≥ 15cm, adults can go skating safely, and the thickness is equivalent to the length of the adult's palm. According to the relevant regulations, the ice layer of the open-air skating rink needs to reach 15 cm before it can be opened to the public. When the thickness of the ice layer is greater than or equal to 20cm, a snowmobile weighing about 0.25t can travel on the ice. The thickness of the ice surface is increased to ≥40 cm, which is about the length of the palm plus the forearm. At this time, the ice can drive and can carry a car weighing about 2 tons. The thickness of ice in natural waters is uneven, and the underwater situation is complicated, so the thickness of ice can't be seen with naked eyes. The skating rink has a professional method to measure the thickness of ice. In the corner of the skating rink, make a small hole in the ice with a steel drill, put the hook in, hook the bottom of the ice, and hold the hook with your fingers. After taking out the hook, directly measure the distance of the hook under the ice with a tape measure. According to the relevant regulations, the ice layer of the open-air skating rink needs to reach 15 cm before it can be opened to the public. The ice surface is measured three times a day in the morning, at noon and at night, and there are five or six test points for each measurement to ensure safety. If you want to skate, you should pay attention to the information of the skating rink to make sure it is safe before you play.
