On the morning of August 31, 2020, the last batch of radial cables was pulled into place and the connection to the inner ring beam was completed - the construction of the tensioning and lifting project for the cable structure of the Sanya International Sports Industrial Park stadium was completed. The upper ring cable reaches a height of 46 meters and the lower ring cable reaches a height of 29 meters, which indicates that the overall condition of the stadium's steel structure and cable structure has reached the design condition.
All domestically produced high vanadium enclosed cables with a maximum diameter of 120 mm, which is the largest diameter used in the construction of a complex indoor stadium, are used in the construction of the cable truss. The used steel cable clamp G10MnMoV6-3 + QT2 is also the first application in construction. It is worth noting that the cross cables between the upper and lower ring cables are made of carbon fiber cables. This is the first time that carbon fiber materials have been applied to long-span spatial structures at home and abroad, leading to a breakthrough in the use of new materials.
After completing the erection of the cable structure, proceed with the erection of the roofing membrane structure. Currently, the project of the stadium of the Sanya International Sports Industrial Park is 80% completed.
