Advanced Techniques Flatten Skyscraper In Japan

A walk in downtown Tokyo, admire many skyscrapers. On the other hand, very few actually pay attention to high-leveled building. Smoothing technique of the skyscraper, the height of the building is slowly disappearing as new techniques flattening buildings.

Flatten skyscrapers require separate art from a technology, especially if the structure is more than 100 meters. Over the next few decades, more and more high-rise buildings are expected to have a period of time for a trim.There needs to be a very effective way for buildings more than 100 feet. Creating a safer work environment, and reduce noise and dust by keeping all demolition work on the building.

Recently, methods to public attention when the contractor began to tear down the Grand Prince Hotel Akasaka example, one hotel in Tokyo. This hotel is the tallest building ever leveled so far in Japan.Generally speaking earlier, when a high-rise building was demolished, the sides are protected, while the upper part, where the heavy equipment doing demolition work, open to the sky. Crane used to pluck debris from the top and bring it to the ground.
But the crane can only be done with a limited height, so this method can not be executed with the building of more than 100 meters. Only a few buildings over 100 meters have been torn down in Japan so far.
Statistics show that most of the buildings over 100 meters in the world torn down after the age of 30 or 40 years. Japan has about 797 buildings over 100 meters, and 99 of them will be 30 to 40 years old in 10 years.
It stands to reason that many of the building will be leveled.Is it really possible to safely dismantle buildings over 100 meters? Research is needed for that.
The main idea is to dismantle the structure in an enclosed space, unlike the traditional way of working in the open air.
Using the roof of the building to create a closed area and carry cranes in the building. The roof is supported by columns derived while making higher floors down.
By working in a confined space, noise is reduced by 17 to 23 decibels, while the dust can be avoided as much as 90 percent. What's more, it's safer for workers than being in the open air.
This method can speed up the turnaround time and the job can continue to run as long as the occupants neighbors agree. This method is also safer for the environment and more energy efficient.
