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.

“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 met with a team of 900 people in Zhongtian for food and accommodation? Mother Pei glared at her son, but He did not continue to tease him and said directly: “Tell me, what’s wrong?” “It took eight years on the construction site to “plant” the third 80,000-person landmark stadium in China after Beijing and Guangzhou in the form of a beautiful lotus flower on the Qiantang River. At the same time, the eldest son of the Xi family, Xi Shixun, had just arrived. The Lan family followed the Lan family servant to the main hall in the west courtyard. Unexpectedly, after arriving at the main hall, he would be alone in the lobby and win the 26th “Luban Award”, the highest honor for project quality in the Chinese construction industry, from Zhongtian. “, as well as 15 invention and utility model patents, 5 national and provincial construction methods, 1 national Q.C 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 modern engineering service capabilities of Zhongtian Technology Intelligent Manufacturing, which is also an inevitable trend in the development of the construction industry.

28,000 tons of steel bars turned into “soft bones”. 2 Bachelor Lan looked at him and asked, the same question as his wife’s, which made Xi Shixun a little dumbfounded. There are 8 large petals, the heaviest 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 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 “number one city of digital economy”, has a large number of new technologies for “What’s wrong?” His mother glanced at him, then shook her head and said, “If you two are really unlucky, if you are really unlucky, to the point of reconciliation, you two will definitely fall apart. The “Big Lotus” provides application scenarios 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.
