Where is the main venue of Hangzhou Asian Games 1 Hangzhou Olympic Sports Expo City is located on the south bank of Qiantang River, across Binjiang and Xiaoshan, with a total area of 583.89 hectares. Among them, the core area 154.37 hectares and the radiation area are 429.52 hectares. As a new landmark of Hangzhou, it is an urban composite functional area with sports events, exhibitions and exhibitions as the leading functions, and integrating cultural creativity, business office, business shopping, ecological residence and leisure tourism. According to its functions, the core area of the Olympic Sports Expo City is divided into Hangzhou Olympic Sports Center with the function of sports venues, Hangzhou International Expo Center with the function of exhibition service venues, super-high-rise twin towers with the function of hotel business office and subway superstructure.

1 Hangzhou Olympic Sports Center

Hangzhou Olympic Sports Center consists of main stadium, gymnasium (swimming pool), small ball center (comprehensive training hall) and tennis center.

The main stadium looks like a lotus, dynamic and elegant, consisting of 28 big petals and 27 small petals. There are 80,000 fixed seats for spectators, with a total construction area of 2 1 010 square meters, which is divided into 6 floors above ground and1floor underground. The steel awning can hold intercontinental and national comprehensive sports games and international track and field and football competitions. BIM is a highlight of this project.

Due to the dual characteristics and complex appearance of the stadium, the traditional two-dimensional technology can no longer meet the requirements, so BIM technology is used for design, from lotus petal modeling to complex grandstand structure and electromechanical pipeline in the stadium. Through the comprehensive inspection of pipelines by BIM models of various disciplines, the construction drawing design is finally coordinated and improved efficiently; In architecture, undulating stands and curved glass curtain walls are the biggest difficulties in design, and BIM technology perfectly shows the undulating stand structure. Curved glass curtain walls are widely used in floor plans, and each glass curtain wall has a different shape. The curved glass curtain wall is accurately divided by parametric design combined with BIM model.

In this project, the designer's inspiration is brought into full play with the help of BIM technology, and builders can use BIM technology to capture the designer's design concept more accurately and truly reproduce the exquisite, grand, smart or solemn architectural modeling in the designer's mind.

2. Hangzhou International Expo Center

With a total area of 19.7 hectares, Hangzhou International Expo Center is a complex integrating five formats: conference, exhibition, hotel, business and office building. With the advanced design concept and excellent engineering quality, it won the "Luban Award" for China's architectural engineering in 20 16-20 17.

Hangzhou International Expo Center has a unique main venue, which adopts the "four beams and eight columns" structure of ancient traditional buildings in China, showing the temperament and demeanor of a big country. The ceiling of the house is also exquisite, with 348 China white copper rafters and 108 irregular red copper arches arranged in a disc shape. BIM setting-out is adopted in the construction process, each rafter is set out separately, and each rafter is accurately positioned and installed, and finally a "big country dome" with shocking and full style is created.

Hangzhou Olympic Sports Expo City has successively become the main venue of G20 Summit in 20 16, the venue of World Short-course Swimming Championships in 20 18 and the main venue of the 9th Asian Games in 2022. After eight years of planning and construction, the Olympic Sports Expo City has become a new landmark on the south bank of Qianjiang River in Hangzhou.

Where is the main stadium of Hangzhou Asian Games? "Big Lotus" is the main stadium of Hangzhou Olympic Sports Center, so it is named after its lotus shape. It will also be the venue for the opening and closing ceremonies of the 2022 Hangzhou Asian Games and track and field events. Recently, the "Big Lotus" ushered in the first official track and field competition after its completion. What's the interior of the stadium like? How was the watching experience? Can you share the game with friends and family in time? With these questions, the author walked into the "big lotus" to find out.

Walking into the stadium, the red runway and green grass can accommodate more than 80,000 people, and the distance between the stands in the stadium can be adjusted according to people's line of sight standards, so that the audience can have the best viewing experience.

The author saw that many spectators were holding mobile phones to broadcast the game on the same day, and some even recorded this wonderful moment in a circle of friends in Tik Tok. "Very shocking, such a rare opportunity, I have been broadcasting live for more than an hour, and the interaction with friends in the live broadcast room is not stuck at all, very smooth." Mr. Li, who is holding a 5G mobile phone live broadcast, said proudly.

In fact, the structural particularity and huge user density of "Big Lotus" are very rare in various stadiums and gymnasiums in China. During the event, more than 80,000 people used the 5G network to send and receive videos and pictures, make video calls and broadcast live ... The demand for network capacity is huge, which brings new challenges to the network communication guarantee of venues.

"The difficulty is that the equipment installation location is very special, and there are many sites, which need to be partitioned. Access to each block must be calculated and allocated. In addition, the construction is difficult and each 5G antenna needs to be installed. " According to the network engineer of Zhejiang Mobile Hangzhou Branch, after on-site investigation, the antenna installation point is between 35 meters and 45 meters, with different heights, and the number of users in the grandstand area is huge, which belongs to the special scene of 5G extremely dense networking and has no historical experience reference.

It is understood that after repeated discussions, the network expert team of Zhejiang Mobile Hangzhou Branch simulated various venue capacity estimation models before and after, designed a multi-frequency and multi-mode ultra-dense networking scheme, and successfully completed the first-stage antenna shaping effect and networking performance evaluation test by using the ultra-narrow beam shaped antenna customized for the Asian Games, which exported the measured basis and valuable experience for the Asian Games venue network security scheme. The test experience will also be replicated and extended to Hangzhou 15 Asian Games venues.

In order to ensure the smooth communication of the first competition of "Big Lotus", Zhejiang Mobile Hangzhou Branch optimized and expanded the internal and external networks of the venue in advance, and conducted several rounds of traversal testing and optimization. During the Games-time, 62 professional backbones were organized to conduct network monitoring and on-site duty on the security areas inside and outside the venue and around it. At the end of the competition, all the network indicators on the site were running smoothly, and the perception was good, ensuring the smooth completion of the work.

In addition, based on the mobile 5G network, Zhejiang Mobile also launched the 5G intelligent game watching application. Through the 5G smart game-watching application, you can "sit" in position C even at home, and watch the wonderful game from an excellent perspective. The audience can turn around, zoom in and slow down on the mobile phone, which greatly enhances the interactivity of watching the game. The bullet time screen output of the wonderful moment can enlarge the moment of the game and fully show the details of the game. These are all due to the large bandwidth of 5G, which can support fast video uploading, high-speed rendering and low-latency transmission.

In the future, with the continuous promotion of 5G network construction, China Mobile will fully complete the construction of Asian Games communication infrastructure, complete the deployment of Asian Games private network, comprehensively build the Asian Games communication security system, integrate the capabilities of 5G﹢AICDE, deepen the 5G application solution of "Smart Asian Games", and promote the comprehensive application of 5G technology in intelligent venues, security, life, watching games, sports security and other fields.
