Emergency prescriptions are also on the way… Wrap the railroad bridge in foil and paint the railroad tracks white
A heatwave that swept the northern hemisphere twisted runways in London, England, and collapsed roofs in Chongqing, China.
According to CNN on the 21st (local time), the heat wave that hit the metropolis like this collapsed helplessly in the heat that melted the asphalt to the railroad tracks.
Flights were temporarily suspended due to problems with the runway at London Luton Airport on the 19th, when the UK temperature soared to an all-time high of 40.3 degrees Celsius.
This is presumably because the runway melted due to the hot heat.
The airport explained that “part of the runway needs repairs due to the high surface temperature.”
According to a University of Pennsylvania official, the heat causes materials, including concrete and asphalt, to expand or crack, CNN explained.
In China, a red warning was issued in 84 cities amid the heat wave, and it was confirmed on the 14th that one of the museum roofs collapsed in Chongqing, located inland in the Midwest.
This is because the tar under the roof tiles has melted due to the heat wave, CNN reported.
In the state of Texas, a water pipe buried underground has also ruptured.
The city of Fort Worth said on the 18th that water pipe ruptures occurred one after another as the ground moved due to high temperature and drought, and 221 out of 476 cases this year occurred in the last 90 days.
In addition, the city authorities estimated that it was also the cause of the residents who were exhausted from the heat and used a lot of water.
All measures are being mobilized to avoid the heat wave as a temporary measure.
In London, the railroad tracks were painted white to prevent exposure to the sun.
In a notice on the 18th, the transportation authority said, “It was confirmed that the railroad was twisted everywhere.
“The temperature of the railway is over 48 degrees,” he said.
Because white absorbs less heat, officials hope it will help reduce heatwave damage.
In London, a method of wrapping iron bridges in foil has also emerged.
The Hammersmith Bridge, built in 1887, was suspended from use in August 2020 due to the risk of corrosion.
The management committee spent £420,000 (about 660 million won) and put world-class engineers in to build a safety system.
The foil can reflect sunlight and create some cooling effect, CNN explained.
