Early this morning, citizens passing by Tiananmen Square were pleasantly surprised to find that the large flower basket of “Blessing the Motherland” was unveiled. Overnight, the basket with a ceiling height of 18 meters was lifted.
Around midnight, more than a dozen vehicles transporting components of the flower bed drove into Tiananmen Square, and more than 100 workers entered the venue simultaneously to start the lifting work of the main flower bed in the center of the square. Most of the components have been processed off-site, and the main tasks on site are lifting and splicing. Four large cranes wave their long arms and place block members in the designated area.
Giant artificial flowers weigh hundreds of pounds each
The whole large flower basket is 18 meters high, the basket body is 16 meters high, the diameter of the basket is 12 meters, and it is composed of sloped flower beds, glass tank belly, glass jar basket plate and basket letter from bottom to top.
There is a covenant in the flower basket
10 giant artificial flowers
: Sunflower, Shandandan, Yingshan Red, Red Plum, symbolizing the red heart to the party and fighting bravely; Peonies and carnations wish the motherland prosperity.
At the request of the flower arranger, the crane lifts the giant artificial flower and inserts it precisely into the pre-fixed steel pipe in the flower basket.
3D scanning helps arrange flowers
Flower arrangement is a delicate task. Each giant artificial flower weighs hundreds of pounds, how to insert it into a 16-meter-tall basket?
“Before hoisting, we have to pre-make a miniature version of the flower basket, commonly known as ‘insert sample’.” Zhang Xianzhe, chief engineer of Beijing Urban Construction Landscape and Tree Company, said,
Using 3D scanning and positioning technology, engineers positioned the position, orientation and angle of each flower onto the model basket.
The GPS positioning system is then used to zoom in on the large flower basket to determine the position of the flower arrangement steel pipe. After the flowers are inserted into the steel pipe, they are manually adjusted to make them more precise and beautiful.
The large flower basket is resistant to 10 level winds
The biggest difficulty of the project lies in the blue plate hoisting and basket belly dragon. The blue plate with the flowers weighed about 60 tons and required two cranes to complete it. When hoisting, the two cranes need to be highly consistent, lifting at the same time, uniform speed and stability, can not occur violent shaking, accurate positioning. This is a great test of experience and technical cooperation.
After several hours of hard work, the big flower basket of “Blessing the Motherland” was officially unveiled. The words “Blessing the Motherland, 1949-2021” are written on the south side of the basket, and the words “Celebrate National Day, 1949-2021” are written on the north side of the basket. The bottom of the flower bed is 45 meters in diameter and has a sunflower pattern, which symbolizes the blossoming sunflower towards the sun. The basket is made of steel frame, and the basket body is made of fiberglass, which can resist 10 winds.
