The Hangzhou Asian Games "face value ceiling" is made like this

The 19th Asian Games in Hangzhou was extended from September 23 to October 8, 2023. In a few days, the Hangzhou Asian Games will usher in the first anniversary of the countdown.

Today, walk into the Hangzhou Olympic Sports Center Stadium together to see that the "face value" of the Hangzhou Asian Games is made like this.

When it comes to the main stadium of Hangzhou Olympic Sports Center, what do you think of first? Big lotus? The venue of the opening and closing ceremony? New landmark in the city? ... Let's listen to the eyes of the architect first, what is this "behemoth".

The Hangzhou Olympic Sports Center Stadium is commonly known as the "Big Lotus". It is the main stadium and track and field project competition in the Hangzhou Asian Games. It is located in the new center of Binjiang District and Hangzhou City in Hangzhou, about 3 kilometers from the Asian Games Village. The land area of ​​the venue is 82,300 square meters, the total construction area is about 216,000 square meters, and the number of seats is about 80,000.

The style of the venue is dedicated to the ancient silk texture and weaving system, and the building body originated from the dynamics of the Qiantang River. The roof is composed of 28 petals and 27 small petals. It is very dynamic and elegant.

During the Hangzhou Asian Games, the Hangzhou Olympic Sports Center Stadium will undertake the opening and closing ceremony of the Hangzhou Asian Games, the Asian Paralympic Games and the Asian Games track and field competition. At that time, 45 countries will expect 700 athletes to participate here, and a total of 48 gold medals will be generated.

According to Gao Yachen, the head of the Civil Construction of the Hangzhou Olympic Sports Center, the Hangzhou Olympic Sports Center Stadium officially started in 2011. It is currently one of the few domestic stadiums that can accommodate more than 80,000 audiences at the same time.

When it comes to the fate with "Big Lotus", Gao Yachen was somewhat emotional. In 2011, he was fortunate to participate in the construction of the main dycles shortly after graduating. While feeling happy, he couldn't help but feel uneasy. "Previously, I participated in the main purpose of real estate projects. Such a large -scale and volume stadium was the first time. You know, you can install more than 80,000 venues, and you can't find a few in China."

Management such a major project, Gao Yachen was under pressure, and also felt that the burden on his shoulders was heavier. From "Mengxin", to the "high workers" in everyone's mouth, unknowingly, Gao Yachen and "Big Lotus" have been with each other for 11 years. Now, when speaking of this domestic premier stadium, he is like a few treasures.

"Big lotus is composed of 28 large petals and 27 small petals. During construction, there are three main difficulties. The scale is large, the standard is high, and the difficulty is high." There are 79 steel structures around the beam node. In order to tackle this technical problem, the expert demonstration meeting of the academicians alone opened five times, opened all day, and then made the model. It takes 1: 1 experimental site to study. It takes half a year from the model production to the first model of the first piece. There are these petals. The heaviest one is 839 tons, which is equivalent to the weight when the Long March 5 takes off. The difficulty can be imagined during construction. "

From project design to construction and completion, today, the "lotus" on the banks of the Qiantang River can be shining, inseparable from a builder like Gao Yachen, despite many difficulties, but can carry city glory at the time of the Asian Games. All participants bring unparalleled sense of accomplishment.
