(Reporter Wu Peng) A blower will be hidden at the bottom of the Olympic flagpole installed in the Bird's Nest, so that the flag can "fly with the wind" at any time. Recently, the Olympic flagpole in the "Bird's Nest" has been installed, and the relevant person in charge revealed that the number of flags fluttering in the wind at the opening and closing ceremonies of the Olympic Games will be different.

There is a blower hidden under the flagpole.

On July 1997, when Hong Kong returned to China, China's national flag "fluttered in the wind" after it reached its peak, which impressed Chinese people deeply. During the Olympic Games, a flagpole with a hair dryer will be installed in the Bird's Nest to ensure that the flag can "fly in the wind" at any time.

According to the relevant person in charge of Yao Long Metal Co., Ltd., the flagpole supplier of Olympic venues, there are 7 flagpoles in the final "Bird's Nest" venue, which are placed on the south and north sides of the Bird's Nest respectively. The most special thing is that the blower under the flagpole is not placed on the ground, but buried underground.

"This is mainly to avoid affecting the beauty of the venue and the photographer's shooting." The person in charge said that after the national flag is hung on the flagpole, it will automatically rise. At this time, the blower began to work, and the wind blew into the flagpole along the pipeline and blew out from the two air outlets at the top of the flagpole. The flag will fly when it reaches the top.

However, buried fans have also brought new problems. If it rains, will water burn the motor? The person in charge said that each blower is equipped with a drainage device to prevent the occurrence of storm water accumulation. This drainage device is also used for the first time in China.

The direction in which the flag flies is decided by the rostrum.

The flag raised to the top will not be blown in any direction. Engineers from Yao Long told reporters that the direction of blowing the national flag should be towards the rostrum.

According to the regulations, the three most eye-catching flagpoles of the champion, runner-up and runner-up will stand on the north side of the stadium, and the flag will fly eastward; There are four welcoming flags on the south side of the venue, and the wind will blow to the west. The engineer said that the flying direction of the national flag is mainly based on the principle that the podium should see the front of the national flag, and it also adapts to the habit of flag-raisers throwing flags with their right hands.

According to reports, there are four welcome flagpoles on the south side of the venue, with heights of 17.5m, 18m, 18.5m and 17.5m respectively. During the Olympic Games, the four flagpoles will respectively hang the flags of the host countries of the last Olympic Games, this Olympic Games, the five-ring flag of this Olympic Games and the next Olympic Games.

The person in charge revealed that only two flags will be raised at the opening ceremony; Only at the closing ceremony will the four national flags fly at the same time. The flagpole adopts manual and electric flag raising schemes to ensure the national flag to rise and fall.

The Bird's Nest was partially opened in April.

In April, the "Bird's Nest" will hold its first test match, but it will not be fully open at that time. Yesterday, the head of the national stadium operation team said that after the completion of the "Bird's Nest", some opening ceremony projects will continue.

The official said that the "Good Luck Beijing" 2008 IAAF Walking Challenge will be held in the "Bird's Nest" in April. At that time, the top stand of the "Bird's Nest" will not be open to the audience.

It is reported that the "Bird's Nest" is expected to be completed in late March and early April 2008. At present, the work of spraying seat numbers is about to begin.
