The Kansai Airport, Built on Two Artificial Islands That Are Sinking, Faces Enormous Challenges That Nobody Can Solve. Understand Why This Innovative Airport Is in This Situation.

The Kansai Airport, located in Osaka Bay, Japan, is one of the most impressive in the world. Built on two artificial islands, it was designed to address space and noise pollution issues. However, since its opening in 1994, the airport has faced a serious problem: it is sinking.

The construction of Kansai Airport was a remarkable engineering feat, costing around US$ 15 billion initially, with an additional US$ 6 billion spent on measures to curb sinking and protect the airport from sea waves. Nevertheless, since its completion, the airport has been sinking at an alarming rate.

The Decision to Build the Airport on Artificial Islands Arose in the 1960s

When the Osaka region was expanding and needed a new airport. The chosen site for the airport faced challenges such as earthquakes and typhoons, common in Japan. To deal with the soft sea bed, which contained 70% water, engineers dried the clay to create a solid base. 2.2 million vertical pipes filled with sand and a huge sea barrier made of rocks and tetrapods were used to protect the airport.

In 1995, it withstood the Great Hanshin Earthquake and, in 1998, survived a typhoon with winds exceeding 60 meters per second. However, in 2018, Typhoon Jebi caused significant damage, flooding runways and forcing operations to be suspended. The airport partially resumed activities a few days later.

The solution to the sinking problem has not yet been found. Engineers have been adjusting columns and increasing the height of sea walls regularly, but this is only a temporary measure. It is expected that the soil beneath the airport will eventually compact completely, stabilizing the situation. Until then, Kansai Airport will continue to battle against time and the forces of nature.

Kansai Airport is an impressive example of engineering and innovation, but also a lesson about the unforeseen challenges that large infrastructure projects can face.

Não adianta pedir a Deus. Jesus disse que não rogava pelo mundo, então não devemos rogar também, pq o mundo jaz no maligno.

Chame os chineses.
Ou o nosso jeitinho brasileiro.
Pode escolher.
Os chineses são mais rápido.
Os brasileiros são mais baratos e criativos

The oldest tree in the world, alive since before the birth of Jesus Christ, is cut down in a scientific study and the case changes environmental preservation rules.

Seen from space, an image taken by an astronaut shows an unlikely oasis in the Saudi Arabian desert, protected by a terrain that slows the advance of sand, surrounded by green circles, remnants of an extinct lake and nearly 10,000 years of preserved history.

An entire island in the Pacific wants to surround itself with a colossal barrier against the ocean to try to escape increasingly violent waves and not be swallowed by the sea in the coming decades.

After ten days orbiting the Moon, science confirms that the astronauts of the Artemis II mission return with altered bodies.

In the Saudi Arabian desert, the world’s largest green hydrogen plant is 80% complete and will use 4 gigawatts of solar and wind energy to produce 600 tons of clean fuel per day when it opens in 2027.

A producer from Santa Catarina started with a poultry farm of just 7,500 birds in 1994 and three decades later manages 21 farms thanks to a simple strategy he learned early on.

China wants to eliminate diesel trucks, betting on electric models that can cut oil consumption by up to 50%, reduce pollution, and change cargo transportation worldwide.

Melting ice is altering the planet’s weather, days are getting longer, Earth’s rotation is slowing down, and scientists are pointing to a phenomenon not seen in millions of years.

More than €600,000 in gold hidden in pots and an “invisible” safe inside an old house turns a small French town into the stage for a discovery that reveals how entire fortunes can remain buried for decades without anyone noticing.

Japan enters the war with the Terra A1 drone priced at $2,000 and turns the math against Putin by taking down swarms of Iranian drones for a fraction of the cost.

Scientists made electrons flow like a frictionless liquid within graphene — the result violated a law of physics that had been in place for over a century by 200 times…
