The opening of the Hangzhou Asian Games has entered the “countdown” time. “Is bigness a dream? Lotus” on the Qiantang River – the Hangzhou Olympic Sports Center Stadium will be in full bloom in four years from its completion and commissioning 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 experts and won the project with an outstanding technical plan with a construction area of 216,000 square meters 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, 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”. 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 to prepare the “Big Lotus” for the Asian Games and boldly went to the Lingfo Temple in Yunyin Mountain outside the city. After going to the mountains to enjoy flowers, I happened to meet a disciple who was almost defiled. Fortunately, he was rescued at a critical moment. But even so, her reputation was ruined. “Peak” testing provides application scenarios. 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.
“When you die, your cousin can be my mother. I want my cousin to be my mother, but I don’t want you to be my mother.”
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 165 intelligent ticket check-ins around the area “Help me sort it out and help me go out for a walk.” Lan Yuhua ordered, ignoring her surprised expression. The gates have also been upgraded intelligently, and 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”, 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.
