With an altitude of more than 4,300 meters and a runway of 5 kilometers, Changdu Bangda Airport is one of the longest civil airports in the world. The climate where the airport is located is harsh, the wind speed in winter often reaches more than 30 meters per second, the temperature in winter and spring is often below MINUS 20 degrees Celsius, and the air density of the airport is only 50% of the sea level.

Tibet Bangda Airport is 4334 meters above sea level and is the highest airport in the world. In the construction of this aid project to Tibet, the Eighth Division of Air Force Engineering and Defense carried forward the old Tibetan spirit of "being especially hard-working, pioneering and dedicated", and built the world's longest 5,500m airport runway in only 83 days on the snowy plateau with cold and oxygen deficiency and bad climate, with more than 63,000m3 of concrete poured and earthwork excavated and transported/kloc-0.2 million cubic meters.
When I first arrived in Bangda, the officers and men generally had rapid heartbeat, headache, chest tightness, nausea and vomiting, and could not eat or sleep. Many comrades carry a bag of cement, and when they walk a few steps, they stop to catch their breath. Carrying two bags, people have been fainting and need to be rescued. The officers and men carried forward the fearless spirit and pushed hundreds of tons of materials into the warehouse. At the beginning of construction, Bangda Gaoyuan was still covered with ice and snow. The officers and men braved the cold and fired air guns, punched holes, and blew the frozen soil loose with explosives before they began to work. In order to complete the task on time with good quality and quantity, in Tibet, where the legal working time is 6 hours, all officers and men work more than 15 hours a day. Severe hypoxia, continuous overtime, long-term lack of sleep, and the physical fitness of officers and men generally declined; Eat two meals a day on the construction site. Rain and snow often wet meals, and many officers and men suffer from enteritis.
During the war, more than a thousand officers and men ate 1000 tablets and 300 bottles of berberine. When the project was completed, Qamdo Army Hospital sent people to have a physical examination. More than 80% of officers and men have heart problems, and 90% suffer from various altitude diseases. Compared with when I first went to Bangda, the average weight decreased by15.8kg.. During the whole construction process, they organized a scientific and technological research team to continuously observe, measure and analyze around the clock in view of the characteristics of high altitude, changeable climate and great difficulty in engineering quality assurance, and compiled a construction plan of 6,543,800 words, so that every working procedure and every link has rules to follow.
Reorganization and expansion
Bonda Airport is the second highest airport in China. The reconstruction and expansion project of Changdu Bangda Airport started on September 28th, 2007, with a total investment of 270 million yuan. The main construction contents include: repairing runway area 10000 square meters, building 65438+2000 square meters station platform, building 4000 square meters terminal building, 3500 square meters parking lot, building air traffic control tower and supporting facilities, and rebuilding business premises.
The construction work in 2008 mainly includes station apron, runway, drainage and enclosure of flight area; Power engineering, auxiliary engineering, terminal building, air traffic control engineering construction, etc.
In the process of reconstruction, the reconstruction and expansion construction enterprise of Bangda Airport signed an employment agreement with the local government, and local farmers and herdsmen were responsible for earthwork excavation and transportation with low technical content. More than 500 local farmers and herdsmen participated in the project construction.
(of a project) completed.
The reconstruction and expansion project of Changdu Bangda Airport is a key project planned and constructed by the Civil Aviation Administration of China and Xizang Autonomous Region in the 11th Five-Year Plan, with a total investment of 289 million yuan. The project started construction in June 2007 and was basically completed in early September 2009. On September 24th, it passed the industry acceptance organized by Southwest Administration. The newly-built terminal building of the reconstruction and expansion project has a building area of 50 18 square meters, and has three systems, including navigation display system, broadcasting system, oxygen supply system, monitoring system, security inspection information system and departure system, which can meet the demand of 4 18 passengers during peak hours. The completion of the reconstruction and expansion project has greatly improved the software and hardware conditions of Bangda Airport and enhanced its comprehensive support capability, which will surely be a social and economic development in Qamdo. In order to ensure the smooth progress of the project, Changdu Terminal of Civil Aviation actively communicated and coordinated with the headquarters of the airport reconstruction and expansion project, arranged personnel to enter the new terminal in advance to install and debug facilities and equipment, and conducted simulated operation drills for all processes, became familiar with the workplace and processes, and made good connections between departments to ensure that all links were not problematic.
Changdu Bangda Airport is 4334 meters above sea level, with a runway of 5500 meters long and 45 meters wide, and the flight zone is 4D. It is the first regional airport in Xizang Autonomous Region, the second highest in the world, with the longest runway and the farthest from the urban area.
Due to years of use, the runway of Changdu Bangda Airport has been damaged in a large area. In order to ensure flight safety, Changdu Bangda Airport was temporarily closed from June 22nd to July 5th, 20 13 for further maintenance.
