The tower crane moves in parallel, drawing a beautiful arc under the blue sky; the blue light of the welding steel structure flashes, reflecting with the white clouds On February 19, at the construction site of Chengdu Dong'an Lake Sports Park, workers were busy at their posts.

As the main hall of the opening and closing ceremony of the 31st Summer Universiade, the sudden epidemic did not disturb the construction pace of "three pavilions in one field": during the Spring Festival, all construction was carried out normally, more than 1000 workers fought under the premise of good protection, and the main hall of the Universiade has entered the stage of steel structure construction.

Start shaping the flying saucer

Chengdu Dong'an Lake Sports Park project started on October 26, 2018 and is expected to be completed in April 2021. In 2020, the construction of the main stadium of the Universiade will enter the "sprint" stage.

Reporters at the opening and closing ceremony of the Universiade main stadium construction site saw that the "flying saucer" shape of the main stadium has taken shape, is carrying out steel structure construction. The stadium is oval, surrounded by 44 29 meter high water pillars, which will "support" the round roof of the stadium in the future.

"The total steel consumption of" one field, three pavilions "in Dongan Lake Sports Park is 27500 tons, which is equivalent to the weight of four Eiffel towers." According to the relevant person in charge of the construction party, the stadium steel structure adopts the form of combination of vertical cross grid and plane cantilever truss, with the maximum cantilever length of 45 meters. The roof of "three pavilions" adopts the combination of orthogonal truss, plane grid and triangle pipe truss to achieve the perfect combination with metal roof and glass curtain wall.

As the main stadium of the Universiade, Chengdu Dong'an Lake Sports Park's "one field, three pavilions" include a stadium with 40000 seats, a multi-functional stadium with 18000 seats, a swimming and diving stadium with 3000 fixed seats and a small ball stadium. The net land area is about 688 mu, including 460 mu for stadium and 228 mu for three pavilions.

It can be seen from the scene effect picture that one of the highlights of the stadium is the pattern of "sun god bird" on the roof. The total area of the pattern is about 27000 square meters, which is composed of 12160 pieces of safety glass. The facade of the "three pavilions" is decorated with horizontal metal louvers with strong sense of science and technology, which can show the effect of gradually turning and opening, and fully reflect the dynamic and vitality of the venue. After putting into use, at night, the stadium like "flying saucer" is shining, and the surrounding "three pavilions" are like a treasure box, where the space and time are interwoven.

How to ensure the quality and speed of project construction? According to the relevant person in charge of the Universiade Office of Longquanyi District, more than 10 project promotion meetings were held in the early stage, laying the foundation for project promotion. At the same time, the construction shall be organized in a scientific way, such as local construction, mechanical construction, etc., and the personnel and construction quantity shall be increased step by step in a planned way. The construction enterprise shall reasonably arrange the construction period to ensure the progress. In addition, we will coordinate with the raw material manufacturers in the area to resume production as soon as possible, and the raw material enterprises outside the area will give support to solve the problem of raw material guarantee, and spare no effort to guarantee the project construction.
