Currently, the ice testing activities of the Beijing Winter Olympics are underway. As the only newly built ice competition stadium for the 2022 Beijing Winter Olympics, the National Speed Skating Stadium, today ushered in its first “mock test.” During the Beijing Winter Olympics, the National Speed Skating Stadium will hold speed skating competitions and 14 gold medals will be born here. So what kind of tests will the venue carry out? At the scene, let’s connect with reporter He Chang from the main station.
Today, the National Speed Skating Stadium conducts an ice test on the field
Headquarters reporter He Chang:For the newly built stadium of the National Speed Skating Stadium, this “test drill” is really much needed and highly anticipated. Because this stadium has a very important goal at the beginning of its construction, which is to build the ice faster, which means that we hope that during the Beijing Winter Olympics, speed skaters will be able to skate on the ice of this stadium. best world record. To achieve this goal, first of all, this piece of ice must meet the highest standards and must be adjusted to the best conditions, and actual combat testing is indispensable.
3360 pieces of glass to create a curved curtain wall “Ice Ribbon”
Headquarters reporter He Chang:So before presenting the specific content of the test, let’s take a look at this new museum. The whole outer curtain wall of this new building is made of 3360 curved glass pieces spliced on the ice surface, there are 22 such flow lines in it, we also call it ice tape, this ice tape actually also means Following the entire trajectory of the speed skater after racing on the ice, the number 22 also implies the concept of Beijing 2022.
The number of test personnel at the National Speed Skating Stadium exceeds 1,000
Headquarters reporter He Chang:Of course, the emotion is more than that, we go into the museum and look. During the entire test event, this venue will host a total of 144 participating team officials, technical officials and athletes. If you add a group of teams and volunteers all over the place, the total number will exceed 1,000.Maybe you will find where these more than 1,000 people are until the end. I can not see it? That’s right, that’s because they are making different work arrangements based on their scheduled work at the moment.
Headquarters reporter He Chang:Specifically, you can view it on my mobile phone. This is the National Speed Skating Stadium workflow layout we got today. You can see that more than 40 items are precisely set according to time. So I think that through this test, said workflow will be further optimized.
Designers create “the fastest ice”
Headquarters reporter He Chang:Now, we have entered the center of the entire stadium, the venue of the game, we can see that there are ice dump carts working on the ice in front of us. So this piece of ice for work is what we just talked about. The National Speed Skating Stadium is trying to build the ice faster. Besides the faster ice, there is another point in particular. The ice making system is used is currently the most advanced and the most environmentally friendly in the world, the scientific name is carbon dioxide transcritical direct cooling ice making system. It sounds very academic, and a simple understanding is the protection of the environment. environment and energy saving, compared to traditional freon.Ice-making technology, using the new technology, can save nearly 2 million kilowatt-hours of electricity each year, which is equivalent to the average electricity consumption of 6,000 households in Beijing for one month.
Headquarters reporter He Chang:Having said so much, the most important thing is how to build the fastest goal for this piece of ice to pass this test competition. To answer this question, we also invited the operation team of the National Speed Skating Stadium to the scene today. . fromDirector Wu Xiaonan came to giveWe answer.
The site is designed for the highest environmental protection and an all-ice multifunctional surface.
Wu Xiaonan, Director of the National Speed Skating Stadium Operations Team:Since the beginning of the construction of the National Speed Skating Stadium, the fastest ice has been our ultimate goal. So through the first ice making and this ice making for our meeting in Beijing this time, we found that its quality will improve every time, which is what we hope for.The first is that the running-in of our ice making machinery and equipment has been further improved. At the same time, the running between the ice machine and the equipment has been further improved, As you can see, the two cars that are currently pouring ice are already completed by our home ice machine independently. In particular, this piece of ice must be tested by athletes in the training and competition of our test activity.
Wu Xiaonan, Director of the National Speed Skating Stadium Operations Team:This morning, the Beijing team has been training on this ice patch for the first time. It is also very important to communicate between the professional athletes of the Beijing team, the coaches and the players. What is the quality of the noodles? How can we run-in and improve with the ice machine? I believe that in this test activity, we will further enrich our ice making experience through running between these things and things, people and things, and people, improving our ice making quality.In future test competitions and even the Winter Olympics, we will gradually improve and finally achieve our goal faster.
Headquarters reporter He Chang:So about this test activity, what specific work will be carried out at the next national speed skating stadium? What valuable experience will you get? We will also continue to pay attention to the scene. (Headquarters reporter He Chang)
