by It is the third largest comprehensive stadium in Hainan Province.
Help sports powers serve the construction of sports culture in Hainan free trade port realize the balanced development of national fitness and competitive sports recently, the first prefabricated stadium in Hainan free trade port, the main venue of the opening and closing ceremony of the sixth Provincial Games in 2022, Hainan Danzhou Sports Center project, which was contracted by China Construction First Bureau, was fully capped, and quickly “landed on the island” with Xiaoxuan Take a look at the main stadium project of 2022 Provincial Games, which is located in the eastern New Area of Danzhou, Hainan, with a total construction area of 101800 square meters.
The lightweight partition board is the most used prefabricated component.
Within 70 days, the roof can be sealed smoothly.
A large number of standardized designs are adopted for industrialized production, and the prefabrication and assembly rate is as high as 51%.
The number is large and difficult.
The steel structures used in the project are prefabricated in the factory, and the construction process on the site is reduced by 30%.
It is called “stone folk house” The three single building concepts of Hainan Danzhou Sports Center project are taken from the famous scenic spot “Millennium ancient salt field” in Danzhou And the local stone residential buildings are dark gray, which fully demonstrates the ancient, simple and stable urban characteristics of Danzhou.
1 company [winter solstice] China Construction First Engineering Bureau’s exclusive secret: how difficult is it to build a Winter Olympic athletes’ village in a high mountain? Praise! China Construction First Engineering Bureau’s success report is back on the snow covered plateau at an altitude of 3670 meters! China Construction First Engineering Bureau’s “great construction site brother” is coming!..
The overall steel consumption of the project adopts space pipe truss steel structure.
Through block mechanical hoisting and manual welding of the trusses in advance, the maximum hoisting monomer weight is 66 tons, and the hoisting radius is 35 meters and 44 meters, which is equivalent to 15 floors high.
Due to the difficulty of installation and the high accuracy requirements, the high-precision total station positioning and measuring instrument is used throughout the whole process to establish the plane and elevation measurement control network by stages, so as to ensure that the accuracy requirements and errors of structural axis network measurement and positioning are not limited Over 5mm, the project team selects the software architecture system to create the whole system model of the curtain wall and systematically optimize the three-dimensional model, so as to form a rolling wave editing and production with strong visual impact ｜ material source of the financial media central kitchen (cscec1j) of China Construction First Bureau ｜ No.
The main construction contents include a stadium that can accommodate 30000 people to watch sports events and literary performances, a stadium with more than 5000 seats, and a swimming pool with more than 1000 seats.
The blue and white sunlight plate is used for the curtain wall, with an area of about 10000 square meters and the metal roof area of about 90000 square meters.
The project is implemented by independent coding for each steel pipe and each block combined with single continuous side assembly technology Now, a total of 72 main trusses are assembled accurately to improve the construction speed.
The total steel consumption is expected to reach more than 9100 tons.
72 main trusses are used to solve the problem of long-span.
The standard board is stacked according to the BIM model The standard plate is sent to the cutting room for on-site “transformation” The discount rate is far lower than the average level of 10% in the industry.
The stadium shape simulates the unique volcanic rock masonry residential building facade design of Danzhou by means of top cutting, highlights the characteristics of marine culture, extracts the image of white waves caused by waves hitting steep stones, presents the wave shaped gathering effect, and the gymnasium natatorium extracts the “Millennium ancient salt field” Through geometric abstraction, the shape of “Millennium ancient county charm Danzhou” The first fabricated stadium project in Hainan Province is the first fabricated stadium project in Hainan Province.
During the hoisting process, the project team uses three-dimensional simulation technology to build a virtual platform for steel structure construction operation, so as to realize the systematic simulation of large-scale steel structure construction and ensure the hoisting safety Full precision and rapid construction “black technology” The stadium curtain wall is a special-shaped curved wall with unique shape.
The construction period can be shortened by half by replacing the traditional manual block installation method with factory prefabricated partition board.
