Qingdao New Airport Observation Meeting on May 12
The high-profile Qingdao New Airport is a regional hub airport designed and constructed by the national “Twelfth Five-Year Plan”. It is the gateway airport in Southeast Asia and the international highest operating level 4F standard design. Qingdao New Airport is located in Jiaodong Town, Jiaozhou City, 39 kilometers away from Qingdao city center. The first phase of construction land is 16 square kilometers, with a total investment of 36 billion yuan. The terminal has two floors underground and four floors above ground. The building area is about 478,000 square meters. After completion, it can meet the annual passenger throughput of 35 million passengers, cargo and mail throughput of 500,000 tons, and the need for 300,000 aircraft movements. Qingdao New Airport is the first domestic single-finger five-finger style. The design idea is the first to be people-oriented. The first phase is star-shaped, and the overall “qi” shape is in line with regional characteristics and inherits the historical heritage. For the first time, the high-speed rail and subway were introduced into the terminal building at the same time. It is the first zero-transfer comprehensive transportation center integrating high-speed railway and subway in China. As the first batch of national-level integrated pipe corridor pilot project, the city integrated pipe gallery was introduced into the terminal for the first time. The introduction of ultra-pure ferritic stainless steel roofing, with a total area of 200,000 square meters, is the world's largest ultra-thin stainless steel roofing project.

The layout of the terminal building adopts the “Starfish” type layout, which consists of the F zone lobby and the ABCDE five corridors arranged in the center of the heart. The total construction area of the terminal building is about 478,000 square meters, of which the projection area of the grid part of the corridor is about 105,000 square meters, the steel consumption is about 8,000 tons, the projected area of the grid part of the hall is about 127,600 square meters, and the steel consumption is about 1.1. Ten thousand tons.
The whole roof adopts a central symmetrical large-span hyperbolic positive quadrangular vertebral grid structure, and the grid nodes are all welded hollow ball nodes. The height of the grid rises gently from the highest point in the center of the hall to the junction of the cornice and the corridor, and the slope of the side skylight changes suddenly.
Rotary lifting construction technology, vertical lifting construction technology and block lifting construction technology were adopted in the construction. Among them, the amount of rotary lifting construction engineering accounts for 38% of the total lifting capacity.
This grid structure advanced manufacturing and construction technology exchange meeting and Qingdao New Airport observation meeting ended smoothly, and the harvest was quite fruitful!
