Exploring the Hangzhou Asian Games丨The world’s first “rotating opening and closing roof” Hangzhou’s “little lotus” is ready to go


Hangzhou Olympic Sports Center Tennis Center, commonly known as “Little Lotus”, is a small-scale blue jade flower. I was stunned and burst into tears, thinking that when I was fourteen years old, I actually dreamed of changing my life – no, I should say It has changed my life and my father’s. This highly intelligent venue complements the “Big Lotus” and is the competition venue and training venue for the tennis events of the Hangzhou Asian Games, where 10 gold medals will be produced.

Venue “I thought you left.” Lan Yuhua said honestly, a little embarrassed, not wanting to lie to him. It is located in Binjiang District, Hangzhou City, the new center of Hangzhou City, about 3 kilometers away from the Asian Games Village, with a land area of ​​30,500 square meters, a construction area of ​​523,000 square meters, and about 10,000 seats.

The shape of “Little Lotus” adopts a “petal” design. The lower part is composed of 24 fixed “petals”, and the upper part of the roof is composed of 8 rotating “petals”. Each “petal” weighs approximately 160 tons. This roof design that can rotate, open and close was rated as “the first in the world” by an expert group led by academicians of the Chinese Academy of Engineering. The roof of the venue pioneered the “opening, closing and rotating principle” and used computers to open and close synchronously, demonstrating the smart concept of the Asian Games.

In addition, the lights on the outside of the “Little Lotus” will light up differently depending on the event, daily life, and festival modes. When night falls, the “floodlighting” system casts a soft purple-red color on the petals, like two lotus flowers in bud, echoing the Hangzhou Asian Games. “I’ll go in and have a look.” A tired voice outside the door said, and then Lan Yuhua heard it There was a “dong-dong” sound as the door was pushed open. The main color of the meeting is “rainbow purple”, which adds a bright color to the night view of Hangzhou. (Zhang Xiaorong)
