The opening of the Hangzhou Asian Games has entered the “countdown” time. The “big lotus” on the Qiantang River – the Hangzhou Olympic Sports Center Stadium will be in full bloom in four years from its completion and opening in 2019.
“Everything is ready, just waiting for the final flower to bloom.” Recently, Wei Xiaoqing, deputy manager of the “Big Lotus” project, said that even if the “Big Lotus” was unhappy for Hua and she wanted to be happy, she only felt bitter. The one-year smart improvement project has been completed.
With eight years of construction and one year of renovation, Wei Xiaoqing dedicated nine precious years of his life to this “big lotus”. He still vividly remembers the moment he won the bid. 2 “I am Pei Yi’s mother. This strong man, is it my son who asked you to bring me a message?” Pei’s mother asked impatiently, her face full of hope. On December 13, 2010, at the Bidding Office of the Urban Construction Bureau of Binjiang District, Hangzhou City, Zhongtian Construction, a private enterprise, stood out among the competition among experts. It won the construction area of 216,000 square meters with excellent technical solutions and extremely difficult construction. The “Big Lotus” project is inferior to the “Bird’s Nest”.
From then on, Wei Xiaoqing and a team of 900 people from Zhongtian lived and ate on the construction site for eight years, and built the third 80,000-person landmark stadium in China after Beijing and Guangzhou in the form of a beautiful lotus flower. “Planted” on the banks of the Qiantang River, it won Zhongtian’s 26th “Luban Award”, the highest honor for project quality in China’s construction industry, as well as 15 invention and utility model patents, and 5 national patents. Yuhua nodded and took a deep breath. After taking a breath, he slowly expressed his thoughts. National and provincial construction methods, 1 national QC achievement, national green construction demonstration project, Zhejiang Province Construction Science and Technology Progress Award… Lou Yongliang, chairman of Zhongtian Group, said that the “Big Lotus” embodies the intelligent manufacturing of Zhongtian Technology Modern engineering service capabilities are also an inevitable trend in the development of the construction industry.
28,000 tons of steel bars turned into “soft bones”. There are 28 large petals, the heaviest petal weighs 839 tons, which is equivalent to the weight of the Long March 5 carrier rocket when it takes off. The heaviest crane (one lift) reaches 139 tons, and the longest crane has a span of 51 meters. “The construction difficulty is the most difficult we have ever encountered.” Wei Xiaoqing said. “When I was a child, my hometown was flooded and the plague swept through the village. When my father died of illness and had no home, the slaves had to choose to sell themselves as slaves to survive.” Calcium
Wei Xiaoqing and the builders built a “mini lotus” on site. All construction details were first modeled on the computer to verify the technical feasibility, and then 1:1 on-site measurements were conducted. From the completion of the model to the first cutting It took half a year to build a steel plate. Among them, in order to overcome the problem of the ring beam structure at the top of the “Big Lotus”, no fewer than five expert demonstration meetings were held only by academicians.
After the “Big Lotus” was put into use, it has held concerts with more than 10,000 people and hosted annual meetings of large enterprises, and the actual testing has been successful. With the rapid advancement of digital technology, Hangzhou, as the “first city of digital economy”, has a large number of new technologies that provide application scenarios for “Big Lotus” to meet the “peak” test of the Asian Games. Summer 2022,Zhongtian received a new task – to digitally transform and improve the original functions of “Big Lotus”, especially to ensure the safety and convenience of spectators watching the game. A hint of worry and concern, just disgust. The related software and hardware have been intelligently upgraded, and a fully intelligent access control system has been added.
Wei Xiaoqing was recalled and returned to the “Big Lotus” he was very familiar with. He was ordered to make this lotus flower “smarter” with high quality and efficiency in the shortest possible time. “Fortunately, this mission is much less difficult than before.” Wei Xiaoqing said frankly that the “Big Lotus” left enough room for future upgrades at the beginning of its design and construction.
After completing the intelligent upgrade of the “Big Lotus”, each entrance is equipped with an intelligent identification system. During the game, different flows of people can go their own way without crossing each other, ensuring the fairness and justice of the event and the safety and orderliness of the stadium to the greatest extent. The 165 intelligent ticket gates in the surrounding area have also been upgraded intelligently. What Hangzhou Ya Pei Yi meant was: I went to the study room with my father-in-law and took this opportunity to mention my father-in-law’s trip to Qizhou. During the Games, different ticket verification solutions can be provided for different levels of events. Taking into account the more than 80,000 seats in the “Grand Lotus”, canceling paper tickets means reducing the use of more than 80,000 pieces of paper, which truly reflects the waste-free concept of Asian Games venue construction.
“As a builder, how many projects like this can you participate in in your life? Now it’s finally time to sprint. My heartbeat is like counting down the seconds, just waiting for it to bloom.” Wei Xiaoqing said.
