The simple and atmospheric at the terminal of the terminal, the two big runways are straight, and the tower clouds of the shape of the plum "bloom" ...

Entering the Huahu Airport of Ezhou, various supporting facilities are renewed. The "fourth in the world and the first Asia" professional freight airport is preparing for the upcoming navigation.

Huahu Airport

Behind the construction of Huahu Airport, what are the difficulties? What are the highlights of construction? In the past few days, the reporter interviewed the relevant construction units of the "No. 1 Project" in Hubei Province.

11th floor filling and consolidating soft foundation

The high -rise building is flat, and the bricks and tiles are found.

The main construction content of Ezhou Huahu Airport includes 2 ultra -long -distance runways, terminals, freight houses, 126 parking apron, and air traffic pipe navigation, freight sorting centers, airline bases and fuel supply engineering.

The construction of the airport is particularly important. The pilot project of Huahu Airport Construction is the implementation of the comprehensive governance project of Malaysia, covering a total area of ​​11.84 square kilometers.

The relevant person in charge of the construction unit of the construction unit stated that during the construction of the comprehensive governance project of the Malaysian Lake, the project personnel need to perform water system governance and flat operations in the 11.84 square kilometer area. Among them, in the main lake area of ​​958,900 square meters, the average thickness of the mud was 5 meters and the deepest part was 17 meters.

"Foundation treatment is the top priority." The person in charge recalled that after the bottom processing of the Mahu Lake, there was a 10 -meter distance from the airport design elevation. For this reason, the project team selected the central southern mountains in the field of the mountains in the southern mountain of 20 to 40 cm in the field of 20 to 40 cm. Earthstone, with 70 to 80 cm as a floor, is compressed to the partitions of the runway area, the terminal building, and other partitions. In the end, after a dozen procedures and 11 floors, the number of earth -reckles in the two -three work areas reached 8.44 million cubic meters, which is equivalent to piled 40 floors heights in 10 football fields.

During the period, they held 4 labor competitions and established 6 party members and 2 young commando to lay a solid foundation for the construction of the airport main project.

It is the first project in the country to “build model construction”

The main building area of ​​the main building of Huahu Airport Transfer Center is 750,000 square meters, mainly including construction, structure, curtain wall, hardcover, electromechanical, and other majors.

The relevant person in charge of the unit said that the main building of the airport transfer center adopted the construction method for the first time in the country. The total number of BIM models exceeded 31 million, and more than 100,000 pieces were cut.

On -site discussion

According to the explanation, the construction of the full model is the traditional two -dimensional construction "blueprint", which is transformed into a three -dimensional visualization form through BIM for deepening design and modeling. Transfer center, then it is actuallyurable. In the specific construction process, the main steel structure of the project with a weight of tens of tons is as small as the position and quantity of the screws, and the three -dimensional drawings after the modeling of the BIM are deepened.

In addition, this project is the first project in the country to apply for the entire process of quality inspection and measurement and pricing of the BIM model in the country. path.

As the first pilot project of the BIM list of the Ministry of Housing and Urban -Rural Development, the project's first BIM component information total table is created to complete a total of 29 professional 30037 component information database covering the three major industries of civil aviation, construction, and municipalities, forming a domestic BIM -based digital construction technology The most complete data dictionary.

Liu Xianlin, academician of the Chinese Academy of Engineering, said: "In -depth use of BIM technology to participate in engineering construction, Huahu Airport's exploration in this field has entered the 'deep water zone' and even 'unmanned areas'."
