Preamble:
Transportation power, bridges and tunnels first. Yesterday, a major artery known as the "Gate of South China" - the Shenzhong Passage was finally opened to traffic, lying across the Lingding Ocean, becoming the world's most difficult cross-sea channel for comprehensive construction.
1. Shenzhong Passage - starting from the miracle of "making something out of nothing".
It's hard to describe the difficulty of construction
The 24-kilometre Shenzhen-Zhongshan Corridor stretches from Shenzhen in the east to Zhongshan in the west, including a 15.9-kilometre-long undersea tunnel and two artificial islands of 4.5 kilometres and 2.6 kilometres respectively. Therefore, at the beginning of construction, it faced countless difficulties and challenges.
First of all, there is the construction of an undersea tunnel, which is "creating something out of nothing" in one sentence, because at the bottom of the sea, there is no place to stand, let alone build, so it is undoubtedly a huge challenge to build a tunnel in such a place.
Secondly, there is the test from the natural environment, here is the ups and downs of the Lingding Ocean, but also in the typhoon-prone area, if there is not enough wind resistance, once encountered by a typhoon, it will cause serious losses to the entire project.
It is precisely because of so many difficulties and challenges that the "power of creating China" of Chinese engineers is even more prominent, and they can create one human miracle after another in such an extreme environment.
2. Shenzhen-Zhongshan Corridor - grasp key technologies and overcome problems
1. Perfect combination of "bridges, tunnels and islands" to achieve seamless docking
In the entire Shenzhen-Zhongshan Corridor project, there is no doubt that "bridges, tunnels, and islands" are the three core difficulties and highlights.
First of all, there is the Shenzhong Bridge, which is also the "gateway view" of the entire Shenzhen-Zhongshan Corridor, where engineers have built a world-class maritime bridge, and moreover, it is also a navigable bridge.
Secondly, there is a 15.9-kilometer-long undersea tunnel, which can be said to be the biggest highlight of the whole project, but also the biggest challenge.
Finally, there are two artificial islands, which are like a "transition zone" between a bridge and a tunnel, and only by grasping the location and time of construction can they be seamlessly connected with other buildings.
2. Innovative technology to achieve precise construction
Throughout the Shenzhen-Zhongshan Corridor project, Chinese engineers have used a variety of high-tech means to deal with various construction challenges.
First of all, it is the technology of "making something out of nothing", here, they first need to have a "see-through eye" that can clearly see every detail of the seabed, which requires the help of high-tech equipment such as lidar.
Secondly, there is also "smart construction", in the whole construction process, through drones, remote sensing technology and other means, real-time monitoring of tunnel construction can be realized, and every inch of land can be clearly understood.
Finally, there is the "seamless docking", in the final stage of construction, engineers need to use satellite navigation and other technologies to achieve the "seamless docking" of bridges and tunnels, and only accurate to the centimeter level can achieve such a miracle.
3. Shenzhen-Zhongshan Corridor - Carrying the Chinese Dream and showing China's strength to the world
1. Made in China, Chinese wisdom, become the country's important weapon
The successful opening of the Shenzhen-Zhongshan Corridor is not only a victory of traffic engineering, but also the pride of Made in China and Chinese wisdom.
2. Convey the "voice of China" to the world and help the "Belt and Road"
With the opening of the Shenzhen-Zhongshan Corridor, more and more foreign friends will come here to personally experience the "magnificent mountains and rivers" of China's projects, and will also be full of curiosity about China's development and construction, which is a kind of "Chinese voice" transmission and a powerful boost to diplomacy.
At the same time, the innovative technology and exquisite craftsmanship displayed by the Shenzhen-Zhongshan Corridor will also become an important part of the "Belt and Road" initiative, promote high-quality development on a global scale, and provide valuable reference and reference for the construction of transportation projects around the world.
Epilogue:
The opening of the Shenzhong Passage is the crystallization of the hard work and wisdom of the Chinese people, and it is also the perfect composition of the Chinese engineers to "sing a symphony". The "creation out of nothing" he shows carries the endless yearning of the Chinese people for a better life and the infinite hope for the future.
It is believed that under the guidance of the "Belt and Road" initiative, more and more "Made in China" and "Chinese wisdom" will "blossom and bear fruit" on a global scale, and will also contribute China's "unique strength" to the cause of world peace and development.
