The “big circle” at the top is the summit club, which is its most obvious symbol and a project with great difficulty coefficient and high scientific and technological content.
This is not available on the previous platform.” 02 it is very difficult to build a slideway overhead in the valley.
From the circular top of the platform to the section line and the bottom grandstand, it perfectly matches the S-shaped curve of “Ruyi”, so it is vividly called “snow Ruyi”.
These venues, which condense the sweat and wisdom of the builders, embody China’s traditional craftsman spirit of excellence and demonstrate China’s determination to host a sports event! We will unveil the mystery for you one by one.
The handle part in the middle of “xueruyi” is the slideway, which is divided into hs140 platform and hs106 standard platform.
Front view of “xueruyi” track and side view of “xueruyi” track (photographed by Xin Jiangqi of Beijing traffic radio), So is the grandstand area at the foot of the mountain “Xueruyi” is a bright spot with an area equivalent to a standard football field.
Those familiar old venues and places have been newly designed, transformed and upgraded.
All sides are cantilever structures.
This innovative design brings great challenges to the construction.
Zhang Li, vice president of the school of architecture of Tsinghua University: “the circular shape you see creates a possibility that the audience can see the state of the athletes starting from behind when you go up without disturbing the athletes.
The construction team used 136 piles, because the pile heights are different in the valley.

The construction technology of the schematic diagram of the grandstand area ✦ 01 installation and unloading technology of large cantilever steel structure helps the peak steel structure installation technical team overcome many difficulties such as hoisting of overweight steel structure components, splicing of long-span components, unloading of super long cantilever structures by using the installation and unloading technology of large cantilever steel structure The deviation is less than two centimeters, which is far less than the standard deviation of 5 centimeters.
“Ruyi” shape.
It falls on the shear wall of the main structure through the conversion truss, with a steel consumption of about 2200 tons.
The main building of the venue is inspired by the traditional Chinese auspicious ornament “Ruyi”.
02 the assembly, transportation and hoisting at the foot of the mountain meet the requirements of the construction period, and “xueruyi” chooses to be built between natural valleys, which increases the difficulty of construction.
Night view of “snow Ruyi” and “snow Ruyi”（ © Xinhua Hebei channel) 01 summit Club – “big circle” brings a unique audience perspective.
It is also the competition venue with the largest amount of work and the highest technical difficulty in the construction of Winter Olympic venues in Zhangjiakou competition area.
The 140 platform is 110 meters long with a drop of 135 meters, and the 106 standard platform is 106 meters long with a drop of 115 meters.
A major feature of the construction of venues for the 2022 Winter Olympic Games is the maximum use of the heritage of the 2008 Summer Olympic Games.
The installation of peak steel structure has been successfully completed.

The prestressed steel truss structure system and double-layer reticulated shell structure are adopted.
The maximum length of the cantilever is about 37m and the steel consumption is more than 2000 tons, which bring challenges to the project.
It not only reflects the dynamic of sports architecture, but also highlights the elements of Chinese culture.
136 piles set up a 168 meter track..
The main structure of “xueruyi” adopts reinforced concrete frame shear wall system, and the roof adopts prestressed steel truss structure system, with a total height of 49m.
From the perspective of spectators in the stand area, the peak club “big circle” peak Club (photographed by Beijing traffic radio reporter Xin Jiangqi) interior view of the peak Club (photographed by Beijing traffic radio reporter Xin Jiangqi) night view of the peak Club (screenshot of Hebei Radio and television station’s video work “so you are such a Winter Olympics)” xueruyi “peak club is a circular building with a diameter of nearly 80 meters, The maximum overhang is nearly 40m.
The gap between the highest point on the top of the venue and the ground at the bottom is more than 160 meters, the highest overhead height is 30 meters, and the maximum slope is 37 degrees.
In the past, ski trails were built on the ridge, but this time, the ski trail of “xueruyi” was built in the valley, surrounded by mountains on three sides, forming a “safe haven”, which can improve the comfort of the competition, but it is very difficult to build ski trails overhead.
In addition, the “xueruyi” summit Club similar to Xiangyun will also bring a unique perspective to the audience.
It is the largest ski jumping venue in the world.

National ski jumping Center National ski jumping center is located in Guqi Road, Chongli District, Zhangjiakou City.
The pile is up to 30 meters high, the deepest pile foundation is more than 20 meters deep, and the maximum difference between the heights of adjacent pile tops is 11 meters.
At the same time, there are also a number of “Transformers” in the venue industry that can take into account summer sports and winter sports.
Foreign ski jumping sites generally have only the top athletes’ departure area, “xueruyi” is the first ski jumping site in the world to set up large buildings in the top departure area.
