Various technologies were utilized in the construction of the new runway at Tokyo International Airport (Haneda Airport), which opened in October 2010.
For the construction of D runway, the advanced technologies were used in various locations, aiming at environmental preservation and aviation services for the ultra-long period of 100 years.
The new runway has the world’s first hybrid structure using a combination of landfill and a pier.
It make use of Nippon Steel Engineering versatile experience in the design and construction of marine structures, such as the anti-corrosion technologies of steel structures installed at sea and the manufacturing technologies of prefabricated jacket structures.
Approximately 500 tons of NSSC270 manufactured by Nippon Steel & Sumikin Stainless Steel Corporation were used to prevent the corrosion of the columns from the jacket sea surface area to the part over the sea.
The “seawater-resistant stainless steel thin-film lining construction” anti-corrosion technology is the method that wraps salt-resistant stainless steel around steel tubes for structural purposes.
For the corrosion resistance of the steel structure components of the pier, an organic protective coating provides a short lifespan and increases the cost of re-coating.
It has longer life than organic protective coating and is excellent in corrosion resistance and low life cycle cost.
Approximately 1,000 tons titanium sheets were used for the titanium cover plates installed on the bottom and side surfaces of the runway pier.
The titanium cover plates have a panel structure with a 1 m width, 12 m length, and 35 mm thickness, manufactured by sandwiching inflammable foam material between an outer titanium sheet and an inner coated steel plate.
The construction using this cover plate is resistant to typhoons and is lightweight, and shows high quake resistance due to its unique structure.
A dehumidifying system was introduced in the inner area covered with highly corrosion resistant titanium cover plates, in order to prevent condensation, and thus achieved the long-term corrosion resistance of the jack steel structure under a tough corrosion environment at sea, thereby enabling the large reduction of maintenance cost.
To connect the different structures of the landfill and pier portions for the D runway, the connecting part have a safe and stable structure for the complicated load and deformation behaviour of both structures.
Steel pipe sheet piles with high load-bearing ability were used to prevent the deformation and sinking of bank protection, ensuring the structure and performance of the runway upon which airplanes can make safe takeoff and landing.
High-quality steel products such as steel tubes for structural purposes and steel pipe sheet piles were used. A total of 750,000 m3 of slag product was also used for the landfill portion extended to 38,000,000 m3.
The new runway at Haneda Airport (D runway) is 2,500 m in length.
The re-expansion project of Tokyo International Airport (Haneda Airport) that started in March 2007 was completed after three and a half years, and the D runway, the fourth at the airport, opened on 21st October, 2010.
Tokyo International Airport, commonly known as Haneda Airport, is one of the two primary airports that serve the Greater Tokyo Area in Japan. It is located in Ōta, Tokyo, 14 km south of Tokyo Station.
Haneda handles almost all domestic flights to and from Tokyo, while Narita International Airport handles the vast majority of international flights.
In 2010, a dedicated international terminal was opened at Haneda in conjunction with the completion of a fourth runway.
This allowed for a dramatic increase in international flights going to Haneda, which previously had only “scheduled charter” flights to Seoul, Shanghai, Hong Kong and Taipei.
Haneda handled 64,211,074 passengers in 2010. By passenger throughput, it was the second busiest airport in Asia and the fifth busiest in the world, after Atlanta’s Hartsfield-Jackson Airport, Beijing Capital Airport, Chicago O’Hare Airport, and London Heathrow Airport.
With Haneda and Narita combined Tokyo has the third busiest city airport system in the world, after London and New York City.
Haneda is the primary base of Japan’s two major domestic airlines, Japan Airlines (Terminal 1) and All Nippon Airways (Terminal 2), as well as low-cost carriers Hokkaido International Airlines, Skymark Airlines, Skynet Asia Airways, and StarFlyer. It is able to handle 90 million passengers per year following its expansion in 2010.
In December 2009, ForbesTraveller.com recognized Haneda Airport as the most punctual airport in the world for two years in a row, with 94.3% of its flights departing on time and 88.6% arriving on time.
