China Economic News Network Zhuhai News Special correspondent Shen reported that the sea breeze that poured into Lingdingyang artificial island from the Pacific Ocean on October 23, 65438/KLOC-0, could not dispel the pride and joy of the builders. After 9 years, the Hong Kong-Zhuhai-Macao Bridge, which was praised as "the Seven Wonders of the New World" by the British newspaper The Guardian, was officially completed. At this point, Hong Kong-Zhuhai, East-West and Changhong are lying on the waves, and the natural barrier is unimpeded. This super project is the pinnacle in the history of bridge construction in the world. The engineer who built this bridge is Lin Ming.

Before that, who would have thought that the cross-sea highway bridge with the longest mileage, the most investment, the most difficult construction and the longest design life would be born in the southeast corner of China? In the project, the artificial island at sea and the submarine immersed tunnel are the most difficult parts of the whole project. Among them, the 6 km deep immersed tunnel is the first offshore immersed tunnel built in China, the largest highway immersed tunnel in the world, and the only deep immersed tunnel in the world, which is recognized as "the most challenging project in the world today". Recently, a week after the opening of the Hong Kong-Zhuhai-Macao Bridge, our reporter went to Zhuhai for an exclusive interview with Lin Ming, general manager and chief engineer of the island tunnel project of the Hong Kong-Zhuhai-Macao Bridge.
Lin Ming told this reporter that in 2005, the Hong Kong-Zhuhai-Macao Bridge project was just put forward. Faced with huge projects and the shortage of funds, coupled with the immature technology, it can be said that for China, it is a height from scratch. Building a 5664-meter-long immersed tube tunnel at sea is already a big problem, so all companies that come to bid are discouraged.
Magnificence of Hong Kong-Zhuhai-Macao Bridge
Faced with such a difficult problem, he decided to have a try. Lin Ming, who had no clue, decided to travel all over the country first, although there were only two tunnels more than 3 kilometers at that time, one was the Oresund Tunnel in Europe and the other was the giant Cana sea-crossing bridge in Busan, South Korea. But at that time, South Korea relied on 56 Dutch experts to fly from Amsterdam to Busan for installation.

Lin Ming told reporters that when he led a team to South Korea to visit the giant sea-crossing bridge, he was rejected. So I decided to cooperate with the Dutch company that was installed for Korea at that time. Who knows, the Netherlands actually offered a consulting fee of 65.438+0.5 billion yuan. In the face of Dutch provocation, I once again expressed the hope that the Netherlands could support the most important part, which was also rejected.
Without outside support, Lin Ming discussed with other engineers and started his own research and development. It is necessary to install 33 reinforced concrete pipelines with a weight of 80,000 tons, a length of180m, a width of 38m, and a height of1.4m into the submarine passage with a depth of 50m and a length of 6.7km below Lingdingyang. After four days of hard work, the first immersed tube of the cross-harbour tunnel was finally installed successfully. However, in the face of harsh offshore environment and geographical conditions, this is only the beginning.
Lin Ming told this reporter that he is well aware that he faces the same problem every day, that is, today may be the last day, so every time he is ready to leave, he will look back at the house where he lived. When it was finally installed in 15 building, what they were worried about came as scheduled, and they encountered the worst sea conditions. It is rare for the Pearl River Estuary to be below 10 degree, and the wave height is more than one meter, so the workers are pushed down on the top of the immersed tube by the wave. Nevertheless, the workers sent the immersed tube back to the house. Life came back, but the installation plan of E 15 ran aground.
Just after the new year, the team started again, carrying it with their bodies and taking time to endure it every day. Since 10, they haven't had a good rest with the team except physical fatigue and mental suffering. Their bodies warned that they lost 40 pounds at 10.
It was not until 20 17 that the last immersed tube was successfully installed that Lin Ming and his team burst out laughing. The immersed tunnel of Hong Kong-Zhuhai-Macao Bridge, the largest immersed tunnel in the world, was successfully closed.
China and even the world's major media are cheering for this great project, while Lin Ming is waiting for the final deviation measurement result, with a difference of 16 cm. The world cheered again, but Lin Ming lifted and docked this big guy, which had been fixed in the deep-sea trough and weighed more than 6,000 tons. After 42 hours of fine-tuning, the deviation was reduced from 16 cm to less than 2.5 mm, narrowing the gap by dozens of times!

In an interview with China Economic News Network, Lin Ming said that he often told the construction team of the island tunnel project of the Hong Kong-Zhuhai-Macao Bridge: "We are tightrope walkers, and we are walking the longest and most difficult tightrope in the world. There are countless processes before and after the project, and every process can't go wrong; There are thousands of jobs in the project, and everyone can't slack off. " The slogan "every bucket is the first" originally put forward in the vibration sinking construction of artificial island steel cylinder evolved into "every bucket is the first" in foundation trench excavation and "the first section of each section" in immersed tube installation ... The whole project sang a song.
During the construction of the island tunnel project, we have always advocated the "artisan spirit" of the island tunnel, advocated that even if a screw is screwed, it should be screwed the most firmly, and the ground should be swept the cleanest, and advocated that everyone should do his best in his post. It once introduced to the project manager a "trick" to check the equipment: touch it by hand. "A device full of dust and oil stains, no matter how well the maintenance log is written, is also fake."
Inspired by Lin Ming, in every construction site of the island tunnel project, the neat site, clean equipment and uniform and standardized clothing all show the spirit of an iron army. This team has successfully broken through one world-class engineering problem after another, pushing the engineering construction to constantly set a new world engineering record. At the same time, since the start of the project, Lin Ming introduced that this team 16 collectives and 9 individuals won national honors, and worker Yan Guan 'an became the first "deep-sea fitter" in China with the spirit of "checking every screw three times", and was known as "a great country craftsman".
In May 20 15, Lin Ming was awarded the honorary title of "National Model Worker". After receiving the model worker medal, Lin Ming hung it on the model of Hong Kong-Zhuhai-Macao Bridge and said respectfully, "The builders on this bridge are all model workers, and we are an iron team."
At the same time, the slogans of "the most beautiful project" and "the most beautiful tunnel" came at him. But in Lin Ming's view, the high-quality projects launched by Lin Ming are not for others to see.
Brief introduction of Lin Ming:
Male, Han nationality, from Xinghua, Jiangsu, born in June 1957, joined the party in May/981.
