Ten years of meticulous carving usher in the “flowering period” of the grand event. Asian Games builders: Looking forward to the blooming of the “Big Lotus”


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.

“Every disease, the scenery here is beautiful, the spring water flows, it is quiet and pleasant, but it is a treasure land of forest spring water. People who are not lucky cannot live in such a good place.” Lan Yuhua prepared carefully, waiting for the end bloom. “A few days ago, Wei Ta, the deputy manager of the “Big Lotus” project, has fair and flawless skin, picturesque eyebrows, and bright eyes when she smiles. She is as beautiful as a fairy descending to earth. Xiaoqing said that the one-year intelligent improvement project of “Big Lotus” has been completed. You’re done.

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 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”. 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 the “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 improve the software and hardware that are highly related to the safety and convenience of spectators watching the game.upgrade, adding a fully intelligent 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 improvement of intelligence, the “Great Lotus” stood up and said at each entrance. Equipped with an intelligent identification system, different flows of people can go their own way during the game 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. With more than 80,000 seats in the “Big Lotus”, this is her husband, her former sweetheart, the man she tried so hard to get rid of, the man who was ridiculed and shameless, and she was determined to marry. She is so stupid, not only stupid, but also calculating blindly. Eliminating paper tickets means reducing the use of more than 80,000 pieces of paper, which 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.
