The hero behind the Hong Kong Zhuhai Macao Bridge Conquer technology, save billions for our country,

This hero is Lin Zihao, who has made a very outstanding contribution to the construction of the Hong Kong-Zhuhai-Macao Bridge in our country, and it is precisely because of his leadership that we can overcome all kinds of difficulties and break through many key technologies to build the Hong Kong-Zhuhai-Macao Bridge.

He is Lin Zihao, an expert in architecture, graduated from the Department of Architecture of Tsinghua University, and has his own views on bridge construction.

He is Lin Ming, chief engineer of the Hong Kong-Zhuhai-Macao Bridge, who faced various technical difficulties, broke through them independently, did not borrow foreign technology, and saved a lot of money for the country to successfully complete the task.

It reflects their dedication to their profession, their responsibility for their work, perseverance, and fearless spirit.

Hong Kong-Zhuhai-Macao BridgeThe construction of offshore immersed tunnels is known as the most difficult and complex technology in the world.

At the end of 2005, Lin Ming.

First contact with the Hong Kong-Zhuhai-Macao Bridge project. The bridge, which connects Zhuhai, Macao and Hong Kong, had to be built with a full consideration of the construction conditions, and it was necessary to lay kilometers of offshore immersed tunnels in a total length of 55 kilometers.

However, the core technology of offshore immersed tunnel construction is called "the most difficult and complex technology in the world" by industry insiders, and only a few countries in the world have mastered it, and China's technology accumulation in this field at that time was almost a blank.

Lack of experience:

The Gangfan Minzhuhai-Macao Bridge is the world's largest sea-crossing project to date, and its immersed undersea tunnel.

It is also the largest in the world. Although Chinese engineers have experience in building cross-river tunnels, as of 2010 they are still very unfamiliar with subsea immersed tunnels.

In the early days of the construction of the bridge, foreign countries maintained a high degree of technical blockade; In the middle of the bridge construction, many foreign technical experiences are not applicable to the actual situation; Therefore, the Hong Kong-Zhuhai-Macao Bridge is a project that integrates a number of global problems.

The reason why the Hong Kong-Zhuhai-Macao Bridge is called a super project:

The most "cross-sea bridge" of all kinds.

With a total length of 55 kilometers, taking into account the navigation needs and aviation height limits, its main project is composed of kilometers of submarine immersed tunnels and kilometers of bridges, that is, "bridge-island-tunnel", which is the longest mileage, the most investment and the most difficult construction cross-sea bridge in the history of China's construction.

Longevity! It is 20 years longer than other bridges in the country.

Unlike other bridge projects in China with a design life of 100 years, the Hong Kong-Zhuhai-Macao Bridge has a design life of 120 years. It is also required to be able to resist 8 levels ** and 16 typhoons. Don't underestimate the extra 20 years, the construction of the Hong Kong-Zhuhai-Macao Bridge almost uses the world's most demanding standards, for example, the average length of more than 130 meters, the diameter of the deep-sea pile foundation must ensure that the plane deviation within 10cm and the inclination within 1 250, but anyone who has a little study of bridge engineering technology will be amazed by the above figures:

The technical and quality requirements are too high!

The amount of steel used is equivalent to 60 Eiffel Towers.

As the world's largest steel structure bridge, the main bridge of the Hong Kong-Zhuhai-Macao Bridge alone has a steel plate consumption of 420,000 tons, which is equivalent to the weight of 10 bird's nests or 60 Eiffel Towers.

The pavement life of the bridge is three times that of the expressway.

The Hong Kong-Zhuhai-Macao Bridge is located on the sea surface, so it has been in a high-temperature, high-humidity and high-salt environment for a long time, and how to do a good job of waterproofing, rust prevention and anti-corrosion is particularly important. According to the design requirements, the service life of the asphalt concrete pavement of the bridge should reach 15 years, which is three times the service life of the ordinary highway pavement.

The precision of the stone is comparable to that of flour.

In order to make the asphalt concrete of the bridge deck particularly strong and compact, the precision of the stone material played a decisive role. The more subdivided the stone, the more it can play the function of asphalt, and the denser the asphalt concrete, the stronger and more durable the bridge deck. It is understood that in order to achieve the above effect, the processing of stone has reached 75 microns, which is equivalent to the flour that everyone eats on weekdays.

It is said that the processing equipment currently in use was assembled by experts from all over the world to find relevant equipment and assemble equipment from several countries.

As we all know, with the continuous development and construction of our country, China, as a world-renowned power, has made very outstanding achievements in many fields, especially in the field of infrastructure technology, with its strong infrastructure strength and tenacious and unyielding infrastructure spirit, and even known as "infrastructure madness" by countries around the world.

Now under China's continuous construction efforts, China is also worthy of this title, since many miracle projects that shocked the world, such as the high-profile Hong Kong-Zhuhai-Macao Bridge, it is enough for countries around the world to see China's infrastructure strength, and now, China has another "miracle project", which is more difficult than Hong Kong, Zhuhai and Macao, but at least half of the Chinese will benefit from it in the future.

It is understood that this "miracle project" reproduced in our country is China's Yellow River project, the overall investment has reached about 80 billion yuan, as the most magnificent water conservancy project in China so far, the main construction location of the Yellow River project is located under the Yellow River, the mother river of our country, due to the instability of the Yellow River, has caused about 1,500 floods so far.

Every time the Yellow River floods, the people in the coastal areas will suffer huge loss of life and property, so the problem of the flooding of the Yellow River has always been deeply valued by our country, and in order to solve this problem, the best way is to make full use of the Yellow River water, so for this purpose, China's Yellow River crossing project has appeared.

China's construction of the Yellow River project, in fact, is to create a huge underwater channel through the north and south banks, so as to transport the water resources on the south bank of the Yellow River to the north bank, in order to eliminate the Yellow River flood at the same time, to meet some water supply problems in the north of the Yellow River in China, but when it comes to the construction of the Yellow River project, the difficulty of this project can be described as very large, compared with Hong Kong, Zhuhai and Macao.

In particular, the construction of two 4,250-meter-long two-way tunnels under the Yellow River has caused great trouble to China's infrastructure team, but in the face of China's strong infrastructure strength, these troubles have finally been overcome one by one.

Now this "miracle project" has made China's water resources more evenly distributed, which also provides a boost for the overall development of our country, and with the water resources dispatch of this project, at least half of China's population has been solved with domestic water. What do you think? Guys, I don't know what you have to say about this?

I've found that it's always easy for people to forget the past. In addition to the Hong Kong-Zhuhai-Macao Bridge, another miracle project - Qinghai-Tibet Railway, have you forgotten? The world's longest and highest railway is also proud of how many people have worked hard to overcome the harsh environment of frozen soil and lack of oxygen.

Miracle Project: 1. The "Yellow Piercing Project" with a total investment of 80 billion yuan 2. The Qinghai-Tibet Railway, which has the highest altitude and longest line in the world, was built under extremely harsh environment and the painstaking efforts of countless people.

The Qinghai-Tibet Railway must be on the list, known as one of the four major projects of the new century in China, and it was built with many difficulties that it overcame many difficulties to build this plateau railway with the highest altitude and longest line in the world.

Yangtze River Bridge, Yangtze River First Bridge, Yellow River First Bridge, Qinghai-Tibet Plateau Railway, Yunnan Railway, High-speed Railway.

The Hong Kong-Zhuhai-Macao Bridge is indeed an achievement that shocks the world, but not only this achievement has shocked the world, but also many achievements in China are shocking. The four great inventions of ancient times can still be regarded as world miracles, not to mention the 173 poverty alleviation policies launched after the founding of the People's Republic of China, the atomic bomb independently developed by China, and China's first aircraft carrier, and the "Yemeni evacuation" that shocked the world.

On March 6, 2015, the Saudi-led coalition attacked Yemen. The coalition offensive was very rapid, quickly capturing nine provinces in Yemen. At the start of the war, some 590 citizens were still trapped in Yemen.

Then, the Chinese shipowners website released a message, announcing that the Chinese Navy would temporarily suspend the escort mission that had been carried out since 2008. At that time, many people speculated that China was going to Yemen to bring 590 trapped citizens home.

Sure enough, on the 29th, the missile frigate "Linyi" of the Chinese Navy appeared in Aden, Yemen, and took away 122 Chinese citizens trapped in Yemen on the same day, and also took 2 foreigners on the way. The next day, our naval fighters took away all the remaining 400 trapped Chinese citizens. Compared with citizens in other countries who are still in a state of distress, Chinese citizens returned to their motherland as soon as possible.

The swiftness of this evacuation is due not only to the high speed of execution by our navy, but also to all our diplomats stationed in Yemen。It is these "literati" who have shouldered the burden of our country's diplomacy, and it is these people who have opened up a safe path for all the people trapped in Yemen in the midst of the war.

Many of China's achievements have been achieved under the blockade of Europe and the United States, and the achievements of high-speed rail have attracted worldwide attention.

Not to mention the opening of other Hong Kong-Zhuhai-Macao Bridges, it is really a happy thing for our country.

There are really many achievements, such as high-speed rail, and the Hangzhou Bay Bridge.

Isn't that Great Wall a shocking masterpiece of ancient China?
