Landmark 81 has a total of 81 floors, 461 m high. This is the tallest building in Vietnam, located in the center of Binh Thanh District, Ho Chi Minh City. The maintenance and technical maintenance of the entire building is performed daily by the management team and staff. Anh Vu – the technical manager of the Landmark 81 building, said that the technical team often had quick briefings early in the morning to determine the arising work to do during the day. At the same time, the technical status of the building, the work done in the previous day must be reported in detail. After that, the group of employees moved to the 79th floor of the building. This is the highest floor accessible by elevator. After that, people will walk up to the 80th and 81st floors (top floor) of the building to do their assigned work. Check the building’s power supply system. All electrical specifications must ensure safety conditions in accordance with regulations. Technical staff use specialized temperature gauges to check the heat at conductor structures and power-using equipment on the 80th floor. This is a routine job to promptly detect problems and limit problems. minimize the risk of accidental fire or explosion. A group of workers periodically maintain the glass. To do this, the worker must move on specialized rigs, in turn, check all the glass panes. The outer glass of the building is reinforced with special materials, ensuring safety and durability. Workers check a building’s cooling system. The staff checks the operating parameters of the elevator. “The building is tall, the elevator is an indispensable element in the operation. We understand this, so we should pay attention to the daily maintenance and technical maintenance, so that the elevator does not cause problems,” said Mr. Vu. to speak. The elevator of Landmark 81 building has a pulling force of 12,500 kg, each car has a load of 2,000 kg, a speed of 5m/s – is one of the fastest elevators in Vietnam. “Working on high-rise buildings requires us to have good health and overcome specific limitations. For example, when it comes to glass maintenance, every worker must overcome fear, focus on work and comply with all protection principles to ensure safety,” said Quang Trung, a technical staff member. Periodic inspection and technical maintenance is carried out in the early morning hours, or when people take a lunch break. Troubleshooting was also implemented urgently. This helps the building operate in a safe condition, and at the same time does not affect the activities of residents, merchants and visitors.

When put into operation in July 2018, the Landmark 81 building has become one of the symbols of Ho Chi Minh City. Inside the building, service-commercial activities take place quite bustling, contributing to the driving force to promote the development of the city in the direction of civilization and modernity.

“We cannot risk the lives (of the astronauts) … The structures and metals on the ISS (are) getting old, possibly leading to irreversible consequences,” Borisov said. Disaster is waiting to happen. Borisov announced that Russia would withdraw from the ISS by 2025. However, he later delayed the time because the country needed to check the technique, decide and inform partners of the plan to build a new space station.

The Russian Space Agency (Roscosmos) also confirmed that it is developing a successor space station for Salyut and Mir, two space stations launched into low-Earth orbit by Russia in the 1970s and 1980s. know that agreements with international partners related to ISS will expire in 2024. Share on television, Borisov said that the new Russian space station will orbit the Earth at high latitudes, helping to see the polar regions better. He leaves open the possibility of inviting foreign countries to participate in the construction of the space station. In the video posted to the Internet, Dmitry Rogozin, the director of Roscosmos, said that the first module of the space station is under development, possibly in 2025. Interfax Modules assembled by Energia cost about US $ 5 billion. Still, the prospect of a complete Russian space station is far from over. Andrey Ionin, a member of the Russian Space Academy, said that the new space station would be “a step backwards”. “ISS’s greatest achievement is not technology, but international cooperation,” said Ionin. Before building the new space station, Roscosmos still has to bring the Nauka scientific module to the ISS at the end of the year. Rogozin said Russia will not withdraw from the ISS until the completion of the new space station. However, the announcement from Deputy Prime Minister Borisov will put great pressure on the US Aerospace Agency (NASA) and its partners. Russia believes the ISS is degrading. Photo: Roscosmos. Space stations over 20 years old have regularly recorded incidents in recent times. In March, Russian astronauts patched a gas leak on the ISS that has existed since 2020. This is not the first time Russia has complained about the ISS. Speaking at the Russian Academy of Sciences in October 2020, Vladimir Solovyov, who is in charge of Russian flights at the ISS, thinks the space station will deteriorate rapidly in the next five years, advising the country to prioritize building. new universe. “The ISS partners will have difficulty maintaining the space station without Russia,” said Vitaly Egorov, the space industry watcher. Science . The magazine says SpaceX’s astronaut transportation services can fill the void left by Russia. Two astronauts installed the support frame outside the ISS station Two NASA astronauts step outside of the International Space Station (ISS) to install supports for new solar panels.

According to the Traffic Newspaper, recently, at Tan Son Nhat International Airport, the mechanic discovered that the Airbus A350 aircraft shell of China Airlines was broken up to 30cm. Before that, the plane landed safely after flying from Taiwan to Ho Chi Minh City. Illustration

During the technical inspection, the mechanic discovered a bird impact near the left wing of the aircraft but could not determine the location and time of the bird’s collision. Illustration

According to calculations by some research units, the A350 aircraft consumes 20% less fuel costs and 30-40% less maintenance costs than the previous generation A330 aircraft. Photo: Airbus

Each A350 is priced up to more than 350 million USD and previously only the “giant” airline Qatar Airways owned these aircraft. Photo: Vincenzo Pace

In Vietnam, as of April 2019, Vietnam Airlines has owned a total of 14 A350s, marking the completion of the wide-body fleet of Vietnam Airlines. Photo: VNA.
