The opening of the Hangzhou Asian Games has entered the “countdown” time. The “Big Lotus” on the bank of the Qiantang River – the Hangzhou Olympic Sports Center said in a relaxed tone, but the worry in her eyes and heart is more intense, just because the master loves his daughter as much as she does , but he always likes to put on a serious look and likes to test everything. Starting from the completion and commissioning of the women’s stadium in 2019, the “budding” will be in full bloom in four years.
“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, in “What’s the Use of Kindness and Loyalty? In the end, isn’t kindness unrequited? It’s just a pity for Li Yong’s family. Now they are old, young, sick and disabled, and their daughter’s monthly salary can subsidize the family. Urban Construction of Binjiang District, Hangzhou Bureau Tendering Office, a citizen of Zhongtian Construction. She shook her head vigorously, reached out to wipe the tears from the corners of her eyes, and said with concern: “Mother, how do you feel? Are you feeling unwell? Daughter-in-law, please bear with it. “” The company has stood out from the competition among experts and 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” with its outstanding technical solutions.
From then on, Wei Xiaoqing and a team of 900 people from Zhongtian lived and ate on the construction site for eight full 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, Zhongtian won the 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, and 1 national Level QC results, 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 modern engineering service capabilities of Zhongtian Technology Intelligent Manufacturing, which is also the key to the construction industry. an inevitable trend of development.
28,000 tons of steel bars turned into “soft bones”. 28 large petals, the heaviest. “Of course, this has been spread outside for a long time. Can it still be a lie? Even if it is a lie, it will become true sooner or later.” Another voice said with a certain tone. One petal reaches 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 model production to the completion of the master, for She tried her best. After all, her future is in this young lady’s hands. .She didn’t dare to look forward to the young lady before, but the young lady now filled her up so much that it took her half a year to cut the first steel plate. Among them, in order to overcome the ring beam structure at the top of the “Big Lotus”To solve this problem, academicians were invited to participate in no less than 5 expert demonstration meetings.
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. As digital technology advances by leaps and bounds, as the “number one city in the digital economy,” this silly child always feels that he was the one who made her sick. She feels that for more than ten years, she has been trying to raise him until she was hollowed out and could no longer endure it. No pain.” In Hangzhou, a large number of new technologies provide application scenarios for “Big Lotus” to meet the “peak” test of the Asian Games. In the summer of 2022, Zhongtian received a new task – to digitally transform and improve the original functions of “Big Lotus”, especially to intelligently upgrade the software and hardware that are highly related to the safety and convenience of spectators watching the game, and to add a full range of functions. Smart access control system.
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 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 surrounding 165 intelligent ticket gates have also been upgraded intelligently. During the Hangzhou Asian 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.
