A pressure cooker worthy of the most anticipated best match in the Champions League. Real Madrid and Manchester City will play the first leg of the Champions League quarterfinals with the Santiago Bernabéu closed, as happened in the round of 16 clash against RB Leipzig. Real Madrid can decide on its own when to play – as happened for example against Villarreal or in the derby – and when not with a ceiling in league matches. Of course, in the Champions League, it must be a UEFA delegate who makes the decision.
With the green light from the governing body of European football, everything is ready to receive Guardiola’s team, which yesterday was impatient to get to know the cover. ”I’m curious to see it. I have never been in a stadium with a roof. Same thing in preseason in the United States, but not in an official match and I’m looking forward to seeing it. Last year it was almost finished. Is it done now? ” he asked. Knowing that it will be played with the roof on and that the stadium will sound in a special way because of the noise, he responded with: “ah ah, very good.” Oh yeah? (in reference to the noise), okay, okay, let’s go see it, “said the man from Santpedor, implying that he was totally unaware of one of the jewels of the white coliseum.
His reflection went viral and many fans applauded what they considered a hesitation from a coach who does not miss the slightest detail. But, in case anyone is still unaware of one of the greatest technological innovations of the merengue stadium, we review its secrets and how it works.
EXCEPTIONAL ACOUSTICS
The roof of the Bernabéu not only allows the club to swell its coffers with all types of events regardless of the weather conditions, but it is a powerful weapon against its rivals, as was already seen in the derby. When it is closed, the white coliseum is a real cauldron and it is even more so with the new installation that has been installed in recent weeks.
As reported by the New Bernabéu stadium construction monitoring website, through vertical work, acoustic membranes were installed on the roof of the new Bernabéu. They are designed to reduce noise pollution to the outside and exponentially improve the interior acoustics at events in addition to waterproofing the roof.
It is undoubtedly one of the jewels of this new white coliseum and will allow the commercial exploitation of the stadium 365 days a year. It is retractable and is made up of twelve trusses measuring 72 meters in length and weighing 72 tons located at different heights to protect the players and fans of the white team from any type of incident that the weather may cause. The roof structure works on its own, supporting its four elemental elements, the two new towers of Paseo de la Castellana and the 2 new pillars of Padre Damián.
Four support points for more than 35,000 tons of weight. An engineering challenge made available to the best stadium in the world
HOW DOES IT WORK?
The new retractable cover is capable of closing and opening in an operation that will be fully automatic and will last approximately 15 minutes for guidance and 20 minutes for complete inflation. It has been based on the concept of inflated membrane cells associated with a guidance technology that allows the opening and closing of the same, which will retract from the middle in both directions in a north-south direction, sliding along rails provided under the longitudinal part of the fixed cover.
The retractable cover with pneumatic cushions is undoubtedly one of the most unique elements of the stadium roof. This innovative aspect has been reinforced with a hybrid steel-composite design of the roof trusses themselves. These advanced materials have been used for a long time in the aerospace industry, the naval industry or the wind industry and their use in construction is expanding.
Each lattice of the retractable roof is supported on cars on rails. When the inner cover is retracted, each beam carriage is guided independently by a rack and pinion mechanism. Once all the lattices have reached their final position, the first beams of the northern and southern parts are in the center, above the playing field. When the beam system has been stabilized in place the cell inflation process will begin automatically.
The opening process occurs in the opposite direction to the closing process. First the membrane cells will be deflated. The intermediate louvers will be unlocked and the horizontal stabilization system will be separated. The beams will then be guided into the folded position under the main deck overhangs.
COVER OPERATION
In order to operate the retractable cover, the first thing to consider is the environmental conditions. In this sense, there are a series of limitations to take into account and which include excess wind at height, precipitation in the form of snow or when the temperature exceeds 40 degrees or drops below 0. In these conditions, the retractable cover cannot be open or close, that is, if the cover is open and the wind is very high, the temperature is high or there is a forecast of snow, it will not operate for safety reasons. The control of all these parameters will be carried out from a control room arranged for the activation and supervision of the retractable cover, operated by experts, and who, under total security, will supervise the impressive retractable cover. The imposing roof is also full of weather sensors (4 optical rain sensors, anemometers, snow sensors, thermometers…).
A technological gem that feeds the oft-repeated “stage fear” at the Bernabéu.
