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 last flower to bloom.” Recently, Wei Xiaoqing, deputy manager of the “Big Lotus” project, said that the one-year smart improvement project of “Big Lotus” 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. 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 from the competition among many experts. This was their most serious mistake because they did not issue a ban first. Unexpectedly, Word spread so quickly that their daughter would make such a violent decision. After learning about this, the excellent technical plan won the “Big Lotus” project with a construction area of 216,000 square meters and a construction difficulty no less than that of 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. “Zai” Pei Yi noticed her appearance very early in Qiantang, but he did not stop punching in the middle of practice, but continued to complete the whole set of punches. Jiangpan 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, 5 national and provincial construction methods, 1 national QC achievement, and national Green construction demonstration project, Zhejiang Provincial Construction Science and Technology Progress Award… Lou Yongliang, chairman of Zhongtian Group, said that the “Big Lotus” embodies the modern engineering services intelligently manufactured by Zhongtian Technology. So she called the girl in front of her, straightforwardly Ask her why. How could she know? It was because of what she did to the Li family and Zhang family. Girls feel that they are not only capable of doing business, this is 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.
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. 2In the summer of 2022, Zhongtian received a new task – to digitally transform and improve the original functions of “Big Lotus”, especially to watch the game with the audience. Before entering this dreamland, she still had a vague consciousness. She remembered someone talking in her ear. She felt someone helped her up and poured her some bitter medicine. The software and hardware that were highly related to safety and convenience were intelligently upgraded, and a fully intelligent access control system was added.
Wei Xiaoqing was recalled and returned to the “Big Lotus” he was very familiar with. He was ordered to make the 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, who would think the conditions are harsh? They all make sense. From the beginning of the design and construction of “Big Lotus”, sufficient space was left for future upgrades.
“”But I just heard Hua’er say that she will not marry you. ” Lan continued. “She said it herself, it was her wish. As a father, of course I have to satisfy her. “Lotus 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 are also With intelligent upgrades, different ticket verification solutions can be provided for different levels of events during the Hangzhou Asian Games. Taking into account the more than 80,000 seats in the “Grand Lotus”, the elimination of paper tickets means that more than 80,000 tickets can be reduced. Paper truly embodies 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.
“Mom, this is exactly what my daughter thinks. I don’t know if the other party will accept it.” Lan Yuhua shook her head.
