China as an infrastructure demon, not only in their own country unscrupulously broke records, this infrastructure speed, has begun to play the world, more and more countries to find China to cooperate, this is not Brazil this time intends to spend 15.2 billion, want to cooperate with China, build world-class projects, and even threaten to surpass the Hong Kong-Zhuhai-Macao Bridge, yes, this time Brazil wants to build a cross-sea bridge.
Speaking of the Hong Kong-Zhuhai-Macao Bridge, this is a world-class project, connecting Hong Kong, Guangdong Zhuhai and Macao bridge and tunnel project, breaking many of the world's best, but also because of its super large construction scale and unprecedented construction difficulties and top construction technology famous in the world, once known as the impossible project, when completed, it can be said to shock the world, after all, Western countries think that this is an impossible bridge.
The construction of the Hong Kong-Zhuhai-Macao Bridge took a total of 9 years and cost 126.9 billion yuan to build this 55-kilometer-long bridge with seven of the world's largest bridges.
1. The world's longest cross-sea bridge
2. The world's longest submarine immersed tube tunnel
3. The world's largest cross-sectional road tunnel
4. The world's largest eight-way shock hammer
5. The world's largest rubber seismic isolation bearing
6. The world's largest immersed tube super factory
7. The world's largest crane ship
The difficulty of construction is also a great challenge, so it is not easy to surpass the Hong Kong-Zhuhai-Macao Bridge, not to say that it can be done, but the cross-sea bridge that Brazil wants to build has been identified by China as difficult not belonging to the Hong Kong-Zhuhai-Macao Bridge, which shows that Brazil's cross-sea bridge project is not so easy.
So what's going on here? What exactly is this project?
Speaking of Brazil, it is also a major developed country, and in South America, it is also the largest country in South America.
However, they made difficulties in building the Salvadoran Cross-Sea Bridge, and they could not build the bridge, but it was an extremely important existence.
Because once the Salvador Cross-Sea Bridge is built, it will be able to promote the development of many places, because there is no bridge connection now, resulting in the usual need to travel around the road, the time is at least 4 hours, or by boat, and the boat also depends on the weather, which greatly increases the travel time, as well as the queuing time, once the Salvador Cross-Sea Bridge is built, it can reduce the travel time, promote exchanges between the two places, and let the coastal areas also be able to develop in a balanced way.
It will also be able to connect Brazil's second largest industrial center, whether it is economic construction, tourism construction or improvement of people's livelihood, etc., can be greatly developed because of this bridge, and can also solve the problem of insufficient land in El Salvador.
It can only be said that the Salvadoran cross-sea bridge is indeed of great significance to Brazil, but it does not have the strength to build this bridge, and when he wanted to abandon the project, a designer of the project said that it is better to ask China to try it.
At that time, the person in charge of Brazil also felt that it was feasible, but he did not expect that the United States would insert a foot in it and wanted to win the project, and Brazil had no way to deal with it, so it thought of a method of public bidding to deal with it.
After the global bidding, the engineering teams of many countries went to Brazil to investigate, but these engineering teams shook their heads after the inspection, including the United States, there was no way, and finally the project was won by China.
However, the difficulty here is no less than that of our Hong Kong-Zhuhai-Macao Bridge.
After the exploration of the mainland engineering team, the sea area where the bridge needs to be built, the water depth reaches 60 meters, and it should be known that the depth of the Hong Kong-Zhuhai-Macao Bridge is more than 10 meters, it can be said that whether it is the natural environment or the geographical environment, there are great differences, and the difficulty is not small, after all, the deeper the water, the more difficult the challenge.
Including for the material, it is also necessary to select, after all, the deeper the water, the greater the pressure, which is also extremely important for the bearing capacity of the material.
And here is still an important waterway, so after the construction of the bridge, can not affect the navigation of large ships, so the waterway must be there, so that the Salvador cross-sea bridge needs to build a large bridge tower, according to the scale, the bridge tower will be larger than the bridge tower of the Hong Kong-Zhuhai-Macao Bridge, it is expected that the height will reach 205 meters, 42 meters higher than the Hong Kong-Zhuhai-Macao Bridge.
The total length of the Salvador cross-sea bridge in the planning will reach about 46.8 kilometers, and overall, the construction difficulty of this cross-sea bridge is not lower than that of the Hong Kong-Zhuhai-Macao Bridge, and even more challenging than the Hong Kong-Zhuhai-Macao Bridge, and the successful construction of the Hong Kong-Zhuhai-Macao Bridge in China, deeply trusted by Brazil, they believe that China will be able to complete, for this bridge prepared 15.4 billion US dollars, to invite China to come to help.
To know that $15.4 billion is not a small number for Brazil, it can be seen that the importance attached to the Salvadoran bridge.
For the mainland, the Salvador Cross-Sea Bridge will be another major breakthrough for us, once successfully completed, then the prestige in the international market will go further, which also means that China's strength is truly recognized by the world, in terms of infrastructure level, China is the real world top.
