A work in front of Casa is unvoyable for everyone. China has a solution: inflatable domes

Anyone who has lived them knows: works can be as annoying as necessary. That they build a hospital, a school or a shopping center next to the house can be a blessing, but it is preceded by months and more months (not years) of dust, noise and a continuous coming and going of excavators, cranes and trucks. In China they have decided to save the neighbors that annoying toll of A peculiar form: covering the works with gigantic inflatable domes.

AND (faithful to his style) He has also decided to do it in a big way.

What happened? That China has had An idea so that the works generate less discomfort to houses, schools, parks, churches and other buildings that surround them: encapsulate them. Literally. Its proposal consists neither more nor less than inflarous ‘bubbles’ that cover the entire extension of the works, temporary domes that reduce noise and dust that the neighbors usually suffer when workers, trucks and excavators begin to move.

The objective: less impact was while operators work inside.

From theory to practice. The use of large inflatable domes is not exactly new. In autumn of 1971 Ibiza already hosted an ephemeral city created with plastic inflatables, Instant City. If the Chinese initiative is news, it is because of its approach (it seeks to minimize the impact of the works) and especially because it has gone from the theory to the facts. And big, in addition. In Jinana populous city of the East of China that acts as the head of the province of Shandong, just deployed an XXL inflatable dome as part of the Honglou 1905 project.

According to Precise Huanqiuthe promoters want to build a large commercial complex there, but they found that the plot in which the works must be developed is in an area full of life, the district of Licheng, near a church, the Shandong University and an institute, in addition to numerous buildings. Thus, the question was obvious: how to get the works forward without the noise, dust, dirt and come and go of trucks to ruin the daily life of the entire neighborhood?

An ephemeral ‘cathedral of 50 meters. The answer revealed it A few weeks ago Dazhong News: Those responsible for the work deployed a large inflatable dome 150 meters long, 100 wide, 50 high and a total area that moves between 20,000 and 30,000 square meters to cover the works. As is. The structure is formed by a PVDF membrane, a very fine material that operators deployed on June 12 with the help of fans.

“The outside of the film is a network structure made of steel cables that keeps it together and then fixes it to the concrete beam at the bottom,” Wang Luren clarifiesHonglou Project Manager 1905. Under the dome there are no columns in addition, which allows operators to move comfortably.

Less dust, less noise. Those responsible for the work ensure that the “ bubble ‘reduces dust emissions by about 90% and cushion in more than 80% the noise of the works. It is also water resistant, which facilitates work during rainy months. However, the idea is that the dome is used during the first phase of the works, while the work progresses at zero level.

For now, it has already served the government to breastfeed. A few days ago none, spokesman for the Foreign Ministry, He presumed that Jinan’s inflatable dome is “the largest in the world.” And insisted: its purpose is to “create cleaner and more silent construction spaces, minimizing the impact (of the works) in the surrounding communities and the environment.” To emphasize the message he published a video of the deployment that have reproduced media such as TN either Gulf News.

And what about workers? The dome may reduce the discomfort of the works between the neighborhood, but … how does it affect the operators that will work inside? If dust and noise do not go outside, do they accumulate in the structure? Won’t it affect temperature? The initiative has raised similar questions, but the promoters ensure that the bubble is also designed for workers.

“Avoid high temperatures” .Luren says that the PVDF membrane blocks 90% of ultraviolet rays and the structure includes a breathlessness at the top to guarantee ventilation. “We will also adjust the construction cycle to, as far as possible, avoid high temperatures.”

A spray system and fog cannons will also help the accumulation of dust under the membrane staying at “a reasonable level”. The roof is also igniphed, is designed to support storms and snowfall and is completed with a system that allows their responsible to adjust the environment.
