by Since the CPC Central Committee The State Council printed and distributed the overall plan for the construction of Hainan free trade port Danzhou Sports Center, the main venue of the sixth 2022 games in Hainan Province, contracted by China First Construction Bureau, was officially put into use recently, 210 days ahead of the original planned construction period.
As the main venue of the first large-scale comprehensive games under the background of the construction of Hainan free trade port, the project has a total construction area of 101800 square meters, including the construction content that can accommodate 30000 people Stadiums for sports events and artistic performances, stadiums with more than 5000 seats and swimming pools with nearly 1000 seats will help the sixth Hainan games become a comprehensive sports event for the whole people to participate in and benefit from, and promote competitive sports in Hainan free trade port Coordinated development of mass sports industry the first cast stadium project of Hainan free trade port is the first cast stadium project of Hainan free trade port.
The steel structures used in the stadium are precast in the factory and assembled on site.
The construction is simple, the labor force is reduced by 30%, the construction waste is reduced by more than 60%, and the lightweight partition board adopts BIM Technology for three-dimensional layout The number is customized by the factory, and the processing loss rate is less than 1%, which is far lower than the average level of 5% of the industry as a whole.
The final project is completed 210 days ahead of schedule.
The smart venue grows a “smart brain” project, deeply practices the concept of lean construction, focuses on scientific and technological innovation Smart construction deeply integrates BIM Technology with project construction, realizes “zero collision” by simulating the installation effect through BIM Technology, solves the key and difficult problems such as saddle shaped long-span steel structure of large stadiums and gymnasiums, complex pipeline comprehensive special-shaped curved curtain wall roof, and applies core technologies such as Internet of things, BIM, big data and AI to build an intelligent platform management system to realize all-round visibility, measurability and Controllable combination of foundation pit monitoring system, tower crane detection system, steel structure health monitoring system, intelligent helmet system, intelligent measuring equipment and other technical means to make the construction site grow a “smart brain” and build a digital, intelligent Standardized smart stadium the facade design of the first stadium in China to use endurance board curtain wall in a large area is taken from the local characteristic landscape “Longmen storm” The project uses BIM Technology to typeset 9072 endurance board curtain walls with different colors to form a wavy surge effect.
It is the first time for domestic venues to use a large area.
The venue metal roof is TPO + decorative aluminum plate.
In order to solve the problem that the welding quality cannot be inspected and the water leakage point cannot be accurately judged after construction, the project jointly develops two utility model patents, in which the roof detection equipment is controlled by the pressure of the vacuum cover Make and observe the bonding state between the coil and the nail plate, and carry out welding quality detection in a non-destructive way.
The leakage detection device accurately judges whether the roof leaks through the detection points, filling the gap in relevant domestic technical fields.
The 36m super long cantilever truss is “millimeter level” Deformation error the stadium adopts a saddle shaped space cantilever pipe truss structure similar to the bird’s nest, with a total steel consumption of 6475 tons, a maximum cantilever length of 36.3 meters, a maximum hoisting radius of 44 meters and a weight of 70 tons.
The project is assembled by using spatial three-dimensional coordinate positioning through simulation calculation and analysis The hoisting unit is assembled on the ground to reduce the difficulty of high-altitude welding and improve the construction speed.
Combined with the stress-strain monitoring data fed back every 60 seconds during the unloading process of the steel structure health monitoring system, the construction safety state is mastered in real time.
After the unloading, the error of the actual deformation value is controlled to be less than 6mm.
