Beipanjiang Bridge
It only took 3 years for China to build the world's largest bridge. However, another Chinese initiative was questioned by the United States as plagiarism. However, the Beipanjiang Bridge is very different from the Golden Gate Bridge in the United States. , the United States questioned China's plagiarism, but actually American experts were collectively slapped in the face. If you want to know why it is actually a joke that China copied Golden Gate Bridge , then please do it three times in a row first, and then Keep reading.
Beipanjiang Bridge
Beipanjiang Bridge itself is not long. Its length is only 1314.4 meters. However, compared with its shorter length, the most proud thing about Beipanjiang Bridge is its length. The height from the bridge deck to the bottom of the valley reaches 200 stories. In addition, the world's tallest bridge is located on the complex terrain of the Yunnan-Guizhou Plateau. It needs to withstand various harsh conditions including heavy rain, strong winds, heavy snow, acid rain, etc. According to the influence of climate and meteorological disasters, those Western media who do not know enough about China's infrastructure construction say that even for their country, it is completely impossible to build such a high bridge in the world in such a harsh geological environment. things, let alone China whose infrastructure capabilities are not as good as theirs.
Golden Gate Bridge
However, after China spent 3 years to complete the construction of the world's tallest bridge, these Western media began to question that China's Beipanjiang Bridge actually copied the construction technology of the American Golden Gate Bridge. This is indeed disappointing. Things that people find very funny: The Golden Gate Bridge is a cross-sea bridge, and the Beipanjiang Bridge is a land bridge across a valley. The difference in their environments determines that even though both bridges use suspension bridge structures, their main structures and construction methods There must be a huge difference, but plagiarism? Assume that the construction of these two bridges is treated as two different exams, and the correct answers from one of the exams are forcibly moved to the other paper under the premise that the questions are different. Wouldn't it be full of errors and omissions?
Let’s take a simple example: As a cross-sea bridge , the Golden Gate Bridge has an important consideration in the design of the bridge, which is how to reduce the corrosion of the salt in the sea water on the metal structure and concrete of the bridge. In the Beipan River, On the bridge, any design to resist sea salt corrosion is basically a useless effort, because the Beipanjiang Bridge is a land bridge with no ocean or sea breeze nearby, let alone the need to deal with the corrosion and impact of salt.
Golden Gate Bridge
In turn, the mountain structure below the Beipanjiang Bridge must be reinforced in advance when it is built, and the small module installation and welding technology used by China on this bridge is basically a waste when used on the Golden Gate Bridge. Budget move: The Golden Gate Bridge is a cross-sea bridge. On the premise that the Americans have large crane ships, once the bridge deck structure is damaged, it can be replaced with the crane ship . With the help of the bridge structure module In a sense, the maintenance of this bridge is much simpler than that of the Beipanjiang Bridge.
Therefore, the Beipanjiang Bridge is a bridge independently designed and built by China. Its only relationship with the Golden Gate Bridge in the United States is that they are both suspension bridges. But if China uses the design drawings of the Golden Gate Bridge to build the Beipanjiang Bridge , that could not be built at all, let alone let the current Beipanjiang Bridge win the title of Miracle Bridge.
