After more than two years of hard work by the builders, Phoenix Stadium, one of the core venues of Xiamen New Sports Center, recently passed the acceptance test and ushered in the first CBA All-Star game. With its unique architectural shape, super-curved roof and curtain wall, and bowl-shaped field core design, the shape of Phoenix Gymnasium has the charm of the curve of a traditional large house in southern Fujian, combining the old with the new and majestic.

Although the shape is unique, it brought huge challenges to the construction at that time, the most difficult of which was the hoisting of the roof steel structure. The Phoenix Gymnasium is 326 meters long from east to west and 350 meters across from north to south. The entire steel structure roof is supported by two giant arches in the north and south.

The two huge arches adopt rectangular space pipe trusses, which are one of the main stress-bearing members of the roof steel structure. The overall inclination is 22° to the outside. The height reaches 85m, which is equivalent to the height of a 28-storey ordinary residential building. The cross-sectional size of the steel pipe is 1500mm×65mm, and the maximum weight of a single component is 221 tons, which is heavy and difficult to weld.

In order to ensure construction efficiency, the construction party selected one SCC11000TM and one SCC3500A to participate in the construction. Wu Shaozheng, an operator of Xiamen Lichang Machinery Co., Ltd., said that the two giant arches were hoisted in multiple sections and then welded at high altitude, which doubled the difficulty of construction. It not only tests the stability of the hoisting equipment, but also tests my operation skills.

I operate this SCC11000TM, which has a solid chassis and feels very safe to use. The hydraulic system and control system are also very good, one hit is accurate, which is very suitable for such high-intensity operation requirements.

Through reasonable personnel deployment and assignment, and at the same time paying close attention to the quality control, in fact, the project completed the target task 15 days earlier than the original plan. In addition to SCC11000TM and SCC3500A, during the total construction period of 880 days in the past, hundreds of machinery and equipment from Sany entered the site, providing a strong guarantee for the completion of the project on schedule.

As a key livelihood project in Fujian Province and a major strategic move for Xiamen City to implement a 100-billion-dollar industry and cross-island development, the new Xiamen Sports Center can host a series of domestic and international high-level competitions after completion. In the future, it will become a new landmark in Xiamen, building a broad platform for the further development of Xiamen's sports industry and injecting new vitality.Editor/XingWentao
