When it comes to the beautiful scenery of mountains and rivers, of course, we can't fail to mention the many rivers in our country. Like the Yangtze River, the Pearl River, the Han River, the Liao River, etc., each place is a place where the river is surging and thousands of horses are galloping!
Where there are rivers, there must be bridges, which not only facilitate transportation, but also decorate rivers and mountains.
For example, the Nansha Bridge in Guangdong is another world-class bridge project in the Pearl River Delta after the Hong Kong-Zhuhai-Macao Bridge, and it is an important transportation infrastructure in Guangdong
In fact, there are many outstanding buildings like this in our country, and it is this that also attracts the majority of scholars to travel and visit.
Not long ago, a tourist from the United States inadvertently photographed a special bridge in my country, which aroused heated discussions among the majority of netizens:It's simply an infrastructure madman, and China's infrastructure is very rebellious!
What kind of building did this American friend photograph?
It turned out that the American tourist photographed a sea-crossing bridge in East China!
What is the bridge that has caught the attention of foreign friends?
In fact, this is a very spectacular in East ChinaTokai Bridge
The bridge can be said to be a major "engineering benchmark" and has an important role as a transportation hub, so the masses feel very admired after seeing itChina's infrastructure is very against the sky, and China's infrastructure has opened the eyes of the people of the world!
The Donghai Bridge is located in the waters of Yangshan Deepwater Port in Hangzhou Bay, Zhejiang Province, and is a cross-sea passage connecting Nanhui New Town, Pudong New Area, Shanghai and Yangshan Town, Shengsi County, Zhoushan City, Zhejiang Province.
The Donghai Bridge starts from Shanghai Luchao Port in the north and passes through the northeast of Hangzhou Bay in the East China Sea to Yangshan Deepwater Port in Zhejiang Province in the south.
The Donghai Bridge was built in June 2002, completed in May 2005, and officially opened to traffic in December 2005.
The Donghai Bridge project is huge and complex, and it is the crystallization of the wisdom of the Chinese people!
The Donghai Bridge plays an important role in urban interconnection and can be said to be one of the important infrastructures in East China.
The total length of the Donghai Bridge is more than 30 kilometers, of which the main bridge is about 253 km.
The design speed of the Donghai Bridge is 80 kilometers per hour, and the bridge deck is a two-way six-lane expressway.
The Donghai Bridge can be said to be a major "engineering benchmark", and the construction and design of the bridge has received unanimous attention from the industry
The technical difficulties of the Donghai Bridge project are mainly reflected in two aspects
The construction of the Donghai Bridge encountered many difficulties, two of which were the most significant.
First, the project construction team needed to overcome the difficulty of ship positioning, which seriously affected the construction survey and main cable erection
The second aspect is that the local climate and environment are harsh, the construction is difficult, and the construction accuracy requirements are high.
The project is difficult, and the workers are working overtime, and they dare not delay at all!
The construction of the Donghai Bridge plays an important role.
The Donghai Bridge is the first successful bridge construction in China to cross the open sea, and the completion of the bridge has laid a solid foundation for the Yangshan Deepwater Port of Shanghai International Shipping Center to realize "port opening, bridge connection and urban use".
The "cable-stayed bridge structure form" of the Donghai Bridge also provides new ideas for the design of cable-stayed bridges in the future, which can be said to be a "benchmark bridge".
It is precisely in this way that the Donghai Bridge has received unanimous attention from the industry, and is even considered a "project of the century" by the majority of construction professionals!
It is understood that in order to successfully complete the infrastructure project of the Donghai Bridge, the state did not hesitate to invest a huge amount of money and invested a lot of manpower.
Therefore, from the beginning of the construction of the project, it has received the attention of all walks of life, and many of them have said bluntly:It's simply an infrastructure madness, and China's bridge construction technology is very "against the sky"!
I have to admire that the construction of the Donghai Bridge has created conditions for the economic take-off of Shanghai and Zhoushan, and has also created a real "bridge" for the integrated development of East China cities!
