As we all know, during the economic depression, large-scale infrastructure development is a good medicine. On the one hand, infrastructure investment has the multiplier effect , which can lead all industries and drive economic development; on the other hand, the improvement of infrastructure will also help maintain the long-term prosperity and growth of a country's economy. Based on this, the United States recently launched a $2.3 trillion infrastructure plan, calling it "a investment from a generation of Americans", which immediately made infrastructure a hot word in the eyes of investors again. So India joined in the fun again and began to publicize the country's infrastructure strength.
Want to break the Chinese record? The railway bridge that India has built for 20 years is about to be opened. According to Observer.com, on April 5 local time, the Indian Ministry of Railways announced that the steel arch construction work of the country's Chenab Bridge has been completed. Once completed, the Chinab Bridge will jump to become the world's highest railway bridge at a height of 359 meters; according to its estimate, the bridge will be delivered to use as early as the end of this year, and will not be later than 2023 at the latest.
Ashutosh Gangal, general manager of the North India Railway Company who is responsible for the construction of the project, said that this day was a milestone because the closing of the arch bridge is the most difficult step in the construction of the Jenab Bridge. Taking this major step, no difficulty is left to the point. Subsequently, the Indian helm Modi excitedly posted a message saying that on this day, India showed the world the country's infrastructure strength and confidence in modern engineering and technology.
It is understood that the Jenab Bridge is a landmark project of India's infrastructure. After completion, the bridge will be 1315 meters long and 359 meters high. It will reach 10,619 tons. It can withstand strong winds, magnitude 8 earthquakes and high-intensity explosions with a speed of 266 kilometers per hour. It has a service life of 120 years and a cost of about 14.86 billion rupees (about 1.3 billion yuan).
At present, the world's highest railway bridge is the Najiehe Super Bridge located in Guizhou Province, China. In 2017, this Chinese bridge also won the Luban Award for the top prize in engineering quality in the domestic construction industry. In order to break the Chinese record, construction of the Jenab Bridge started as early as 2002. It was originally planned to be completed in 2009. However, nearly two decades have passed, and the Jenab Bridge is still under construction.
Create a new "national business card"! China's bridges have set many world's firsts
In fact, among the top 100 new high bridges built by mankind in the 21st century, China has 90; now China's bridges have become a "new business card" of our country, setting many world's firsts.
For example, on December 11, 2020, the world's first high-speed railway suspension bridge, Wufengshan Yangtze River Bridge, opened and operated, creating seven world firsts; on October 24, 2018, the world's longest cross-sea bridge, , Hong Kong-Zhuhai-Macao Bridge, , was officially opened to traffic and operated, and is regarded as the ", Mount Everest " in the world's bridge community. The completion of the Hong Kong-Zhuhai-Macao Bridge also marks China's move from a bridge power to a bridge power...
It is worth mentioning that with strong infrastructure strength and reasonable quotations, in recent years, China's bridges have also begun to go abroad on a large scale and go to the world: Indonesia's Sima Bridge, the United States' New Bay Bridge, the Panama Canal Three Bridges , Malaysia Penang Second Bridge, Morocco's Mohammed VI Bridge, Bangladesh's Padma Bridge and other famous bridges are all built by Chinese companies. According to Xinhuanet, the number of large-scale bridges under construction and construction of China Railway Bridge Bureau and China Communications Construction Second Aviation Administration alone has exceeded 50 large-scale bridges overseas.
