Now, it has a new name – “ice cube”
. 
“Guo Jingjing and others won the gold medal there.” He pointed to the 10 meter platform in the distance
. 
The reality is quite different
. 
These data will directly affect the coefficient of friction between curling and ice
. 
In this way, there will be no “water” in the water cube
.
Curling glides rapidly on the cobblestone road with dense freezing points
.
In April 2016, the international curling Federation held the men’s curling World Championship in Basel, Switzerland, inviting Yang Qiyong and Zheng Fang to see the competition and learn from experience
.
The curling hall is full of lights, cameras and a large number of spectators
.
After we decided to undertake, we realized that curling competition was an extremely difficult “hard bone”, which required high technical requirements for the venue and required a solid concrete base
.
“All its designs are related to water
.
“In 2008, athletes broke 21 World Records 24 times in this pool
.
In Zheng Fang’s words, ice is very “sensitive.”
.
Yang Qiyong knows that we can’t wait for “death”, we have to save the swimming pool! At the beginning of 2016, contradictions were already on the way
.
“The audience will come as soon as they arrive, and it will be broadcast on TV.” Yang Qiyong said
.
Water or ice, summer or winter – this difficult proposition of one of two choices is horizontal in front of the Winter Olympic team
.
The National Swimming Center (Water Cube) is the first stadium to be completed and transformed, and it is also the first time in the world to use intelligent technology to build a swimming pool ice rink
.
At that time, the water cube was still an open space, and this “blue landmark” located on the west side of the central axis in the future still remains on the drawing of the design scheme of the winning Pavilion
.
With the continuous sliding of curling on the track, repeated ice repair by ice makers, and even some changes in the indoor environment, subtle changes have taken place on the track surface
.
Unexpectedly, this preconceived decision puts the fate of the water cube in a dilemma: the curling competition of the Winter Olympics has always been frozen on the concrete structure
.
The “ice” of curling competition is very particular
.
In the 1990s, simple ice was laid on the swimming pool for people to skate
.
In addition to being “emotionally hard to accept”, he has a real “economic account” in his hand: relying on the aura and pull of the summer Olympic Games and people’s love for the Olympic heritage, the tourism revenue of water cube has reached one third of the total revenue, which is second to none in China
.
“The Chinese diving ‘dream team’ won all the gold medals except the men’s 10 meter platform.” The glory of the pool is like yesterday
.
Once poured, the pool is abandoned, which means giving up the summer Olympic function of the water cube
.
From the bottom ice to the refrigeration pipeline, and then to the ice surface of the competition, it usually takes about 10 working days for the world’s top ice makers to pour the treated pure water dozens or hundreds of times with a thin water pipe to form the freezing point
.
Without water, the house has no soul
.
Once the track is destructively demolished, the equipment and machinery invested by tens of millions of people in the background will be abandoned, and the cost will be huge
.
“The bidding group asked us if it was OK to hold a curling competition
.
In the story of Zheng Fang, the chief designer and deputy chief architect of Beijing Institute of architectural design and research, I can feel that I don’t want to be specific
.
In the meantime, a bold idea flashed: can we swim in summer and skate in winter to make the water cube “amphibious”? “Water ice conversion”, which is unprecedented in the history of the Olympic Games, brings the hope of breaking the game
.
According to the plan, the water cube will be transformed into an “ice cube” to undertake the curling competition
.
Back on July 31, 2015, the right to host the 2022 Winter Olympic Games will come to Beijing
.
If you don’t want to pour concrete, there’s no other way
.
“Ice cube” with a new look
.
On the one hand, it is one of the important Olympic heritages that Chinese people have a special complex, and it is the “fastest swimming pool in the world” that has set 24 world records; on the other hand, it is the strict standards of curling venues, the strict control of the International Olympic Committee and the solemn commitment of “science and technology Winter Olympics, green winter Olympics”
.
Inside and outside, from structure to function, it’s all about water
.
Curling track is not an eternal horizontal ice surface
.

.
The ice layer, 45 meters long and 4.75 meters wide, with a thickness of 4 to 5 cm, is actually like a piece of “cut cake”
.
We are here to swim and play
.
If it is to be held in the water cube, it can only completely give up its original function and pour concrete in the swimming pool
.
Before that, there was only one Japanese swimming pool in the world
.
Children like it very much
.
What is more disheartening is that the research on ice surface performance was still blank in China at that time
.
You see the bubbles on the roof above, polygonal air cushions, like water molecules, envelop the steel structure of the house
.
Yang Qiyong knew that it was time to “engage in close combat”
.
Curling competition requires that the humidity of the venue is below 30%, the ice temperature is about – 8 ℃, the air temperature is 10 ℃ one meter above the ice, and the temperature in the venue is less than 16 ℃
.
At the end of 2015, the international curling organization sent people to visit the water cube for the first time and put forward the requirement of pouring concrete in the swimming pool
.
Yang Qiyong, general manager of National Swimming Center affiliated to Beijing state owned assets Corporation, is the most unacceptable
.
Phelps won eight gold medals alone Looking to the other side, “there’s a water park over there
.
With years of construction engineering experience, structural engineer Yang Qiyong is confident of laying detachable stable support structure in swimming pool
.
They went to Basel with the water cube “water ice conversion” program.
.
Since 2004, he has been working in the water cube
.
However, ordinary skating for recreation and curling competition at the Olympic level were difficult to transform
.
Starting from a field engineer, Yang Qiyong witnessed the rise of the venue, the 2008 Olympic event, and then thousands of day and night operation of the venue, and countless people came to admire him
.
If you’ve ever touched the track, you’ll be surprised that it’s not a smooth ice surface, but a lot of small particles scattered, with different sizes and unevenness, which together account for about half the area of the ice rink
.
The preparatory time flowed through everyone’s reluctance and contradictions
.
It’s not the idea of fairies
.
In a word, the air temperature, humidity and the distribution of air flow field always affect the quality of the track
.
In the most famous venue in China, the crystal clear blue membrane structure, it seems to be perfect to entertain visitors from all over the world
.
They produce a lot of heat and bring various effects to the ice
.
As the name suggests, “water ice conversion” is to add ice functions on the basis of retaining water functions, so as to realize the exchange of water cube and “ice cube”
.
There’s even a baby swimming pool in it.” “Water is the soul of this building,” Zheng Fang said repeatedly
.
Where is the water cube going? Photo source: Vision China 1 “no water, no soul” abandons swimming pool
.
We watched the video on the Internet and felt that compared with hockey and speed skating, curling didn’t have much range of motion, so it should be easier.” Yang Qiyong recalled
.
Therefore, to hold a curling competition in the water cube is not only to “freeze out the standard ice”, but also to comprehensively improve the temperature, humidity, ventilation and energy saving in the venue
.
This is also a clear requirement of the international curling organization
.
So far, the water cube has received 27 million tourists and held more than 1600 activities
.
Two old friends who have been fighting side by side for many years are wandering around the pool
.
To join the bid for the Winter Olympics, the unique temperament and influence of this venue have been loved by the International Winter Olympics and international curling organizations
.
But when you go up to the ice, you don’t have much confidence
.
The ice maker should lay each layer in order
.
” For ten years, international swimming and diving competitions have been staged as scheduled every year
.
