Today we will talk about the bridge in this article, but this bridge is the crystallization of modern wisdom, and it also has many "most" words. This bridge is the Hong Kong-Zhuhai-Macao Bridge. We must have heard of the Hong Kong-Zhuhai-Macao Bridge, but we are still unfamiliar with the heroes behind it.
The construction scheme of Hong Kong-Zhuhai-Macao Bridge is put forward, and the construction is difficult.
The construction plan of the Hong Kong-Zhuhai-Macao Bridge was put forward in 2005, that is, 15 years ago. At that time, the scientific and technological level of bridge construction in China must not be compared with now, so the reality is that the scientific and technological level of immersed tunnel, an important part of bridge construction in China, has not reached the international level, which has become the most difficult barrier for bridge construction. However, in this case, the media at home and abroad are keeping a close eye on the construction process of the bridge, and its large workload and difficult construction environment are unprecedented in the world.
At that time, the construction of the Hong Kong-Zhuhai-Macao Bridge faced three major difficulties. First, the bridge needs to build immersed tunnels at sea, but before that, all immersed tunnels in China added up to less than four kilometers, and the immersed tunnels in the Hong Kong-Zhuhai-Macao Bridge were nearly six kilometers, so our immature technology became the biggest difficulty.
Secondly, the environment this time is completely different from the past. This is the first time we have built it on the high seas, which can be said to be an exploration from scratch. Finally, because the construction of this bridge is too difficult, many companies that come to bid have no courage to undertake this problem, so the shortage of funds has become a big problem. In this case, the construction of the Hong Kong-Zhuhai-Macao Bridge falls on the shoulders of chief engineer Lin Ming, who is the figure behind the bridge.
The construction process faced many setbacks, and finally we chose to solve the problem independently.
In 2007, Lin Ming and his team began to inspect the tunnel construction. At that time, there were only two bridges with tunnels exceeding three kilometers in the world, one was the Oresund Tunnel in Europe, and the other was the Jujia Sea-crossing Bridge from South Korea. South Korea was carrying out the same project at that time, but their installation was completed by Dutch experts. Lin Ming led his team to South Korea, hoping to visit their buildings and equipment, but the Koreans refused. No choice, they had to cross the bridge by boat and took some photos.
The indifference of Koreans made Lin Ming determined to cooperate with the most advanced and experienced companies in Europe, so they came to the Netherlands, hoping that the Dutch side could provide us with technical help, but the Dutch side actually offered a sky-high price of 654.38+0.5 billion yuan.
Lin Ming's team had many negotiations with the Dutch side, and we tried to reduce the price to 300 million RMB, but this price was teased by the Dutch side, and finally the negotiations between the two sides ended in failure. The road to cooperation with the Netherlands is impassable. In the end, there is only one way left, that is, independent research, independent development and independent construction.
But there is no template to refer to, and other countries refuse to help us. Lin Ming's team is almost exploring on a blank sheet of paper, but he still firmly believes that we can definitely complete this world problem. Once we overcome this problem, we will have the core technology and will no longer be subject to others.
Foreign engineers and media are also paying close attention to the construction of China Bridge, and they even question whether engineers in China can do it. Needless to say, engineers in China can of course. In May 20 13, after 96 hours of uninterrupted conquest, the first section of the cross-harbour tunnel was successfully installed, which was a leap-forward step in the construction of the bridge. This step represents that engineers in China can completely build the cross-harbour tunnel by themselves. Of course, the first section is a success, and it is also the beginning, because the installation behind it cannot be simply copied, and the construction risk is greater in the face of more difficult offshore environment.
During the installation process, the workers were faced with many life-threatening, many faults and great pressure. In the past ten years, Lin Ming has been firmly standing on the construction site, and he looks gaunt after losing forty pounds. 2065438+In May 2007, the last immersed tube was installed. At this time, cheers rang out from the ship, and the world's largest immersed tunnel was successfully built. The eyes of China, including the world, are focused on this bridge. China engineers used their own wisdom, and China workers used their own persistence to complete this huge project.
The bridge was put into operation in June, 20 18 10, and the Hong Kong-Zhuhai-Macao Bridge won the Luban Award for Chinese Construction Engineering. 14 years, Lin Ming completed this unprecedented great project, overcame technical difficulties, and saved 654.38+500 million RMB for the country.
Bridges bear the direction of progress, and "great country craftsmen" bear the direction of the future.
In the past ten years, Lin Ming has been working hard to build a cross-harbour tunnel. As a craftsman, Lin Ming built countless bridges in his life, but the success of the Hong Kong-Zhuhai-Macao Bridge must be the most meaningful. Before going to college, Lin Ming worked as a farmer and worker and learned many basic skills in the factory. In this industry, Lin Ming is undoubtedly excellent. He likes to take root at the grassroots level, like to stress principles and work hard, which has also benefited many of his workers.
The success of the Hong Kong-Zhuhai-Macao Bridge is not the efforts of one person, but the joint efforts of thousands of participants. High-quality high-tech projects show China's scientific and technological strength, and show our unity and high demands. At first we were confused and hesitant, but gradually we dared to rely on our own strength to solve the problem. Bridges carry the way forward for pedestrians, but many "great country craftsmen" who build bridges carry the future of our nation.
The successful construction of the Hong Kong-Zhuhai-Macao Bridge has made many achievements in the world. This is a big project of a big country, which embodies China's comprehensive national strength and national cohesion. It can increase our intelligence and make the international community look at us with new eyes. The Hong Kong-Zhuhai-Macao Bridge connects Hong Kong, Macao and Zhuhai. As the "Mount Everest" in the bridge, it is not only a miracle of China, but also a miracle of the world. Finally, technology determines the future. Our country has ushered in a leap through the construction of the Hong Kong-Zhuhai-Macao Bridge. Its role and influence are immeasurable, and the people behind the bridge are even more national heroes.
