Takeoff 丨 3D ground penetrating radar traversed 248,360 meters at Beijing Daxing International Airport
Release time: 2019-07-31
On June 30, 2019, China's largest comprehensive three-dimensional transportation hub, the main project of Beijing Daxing International Airport was completed!
Beijing Daxing International Airport, "Phoenix Spreads its Wings"!
Beijing Daxing International Airport is the largest airport in the world. The new airport covers a total area of 41,000 acres, and covers an area about 63 Tiananmen Square, with a total investment of 80 billion yuan. It took 4 years. The first phase of the flight zone has four runways, and it is a hub for super-large international aviation integrated transportation connections.
The construction of the first phase of Beijing Daxing International Airport is in accordance with 2025:
72 million passenger throughput
吨 Cargo and mail throughput of 2 million tons
620,000 aircraft movements
Of the four runways in the first phase, the West Runway 1 and the West Runway 2 were completed in September 2018; the East Runway was completed in November; after the North Runway was completed, all 4 runway surfaces were realized.
Runway taxiway acceptance
10天，包括跑道，平滑道以及航站楼南侧停机坪，其中跑道有东跑道，北跑道，西一，西二四条跑道，跑道长均为3800米，每条跑道测13趟；平滑道六条，长度也都是3800米，每条平滑道测2趟；航站楼南侧停机坪长约860m，需测6趟。Beijing Daxing International Airport's entire runway taxiway and other underground structure testing site data collection time is10days, including therunway, smooth road and the south apron of the terminal building, including runway east runway, north runway, west one, west There are two orfour runwayswith a runwaylength of 3800 meters, andeach runway measures 13 trips;six smooth roadsalso have a length of3800 meters, and each smooth track measures2 trips; the apron on the south side of the terminal is about860mlong, which needs to be measured6 trips.
完成 Which means it needs to be completed within 10 days
3800m × 4 × 13 + 3800m × 6 × 2 + 860m × 6
248360m检测任务A total of248360mdetection tasks
The detection task is tight and the task is heavy. And as the top priority of airport engineering, there are high requirements for the accuracy and quality of data during the runway taxiway detection process.
和天线阵技术 ，是一套高分辨率的真正的三维地下成像探测系统 。 The 3D ground penetrating radar of the Norwegian 3D-Radar company uses an innovative frequency stepping radar technology and antenna array technology , which is a set of high-resolution true three-dimensional underground imaging detection systems .
