"Qianhai gets off work, goes to Zhongshan for a meal, has a meal, and then goes back to the depths, and is cool."
Today (June 30), the Shenzhen-Zhongshan Corridor was officially opened for trial operation. Many netizens are full of longing: "Add to the check-in list", "Arrange a self-driving tour", "You must experience a great project by car".
"The steel dragon Tengwan District, Changhong Lying Wave Frame Thoroughfare." The Shenzhen-Zhongshan Corridor is the core transportation hub project of the Guangdong-Hong Kong-Macao Greater Bay Area, with a total length of 24 kilometers, integrating "bridges, islands, tunnels and underwater interconnection", and is currently the most difficult cross-sea cluster project in the world.
The 7-year construction of the Shenzhen-Zhongshan Corridor has been full of highlight moments, which makes people feel emotional; Major breakthroughs again and again make people full of pride. According to reports, the Shenzhen-Zhongshan Corridor has set many "world's best": the world's largest span full offshore steel box girder suspension bridge, the world's largest offshore suspension bridge anchorage, the world's highest suspension bridge wind speed, the world's longest two-way eight-lane submarine immersed tunnel, and the world's widest submarine steel shell - concrete immersed tunnel......
Each "world's best" means that China has achieved new leaps and achievements in these aspects, and has demonstrated China's remarkable strength time and time again.
"After winning the Hong Kong-Zhuhai-Macao Bridge, there is no bridge in the world that Chinese cannot build." Previously, Lin Ming, chief engineer of China Communications Construction Co., Ltd. and engineer of the island tunnel of the Hong Kong-Zhuhai-Macao Bridge, said. This is not an lie, the construction of the Shenzhen-Zhongshan Corridor, which is extremely difficult, can pass the delivery and acceptance, which proves that China has unique advantages in the construction of super bridges.
The Shenzhen-Zhongshan Corridor integrates "bridges, islands, tunnels, and underwater interconnection", from building bridges to building artificial islands, and then to laying tunnels, each link is not easy and cannot be lost. From "falling on the tip of the waves", to "leading in the wind", and then to "embroidery on the bottom of the sea...... Which one is easy?
One detail is that at the beginning, the first section of the immersed tube of the Shenzhong Passage and the buried section of the West Artificial Island were accurately docked and installed on the seabed, completing the first "kiss on the seabed". "Kiss under the sea", this expression is romantic, but in practice it is difficult.
In the whole project, the undersea tunnel of the Shenzhong Passage is called "one of the most technical and difficult control links". According to reports, the immersed pipe section of the undersea tunnel of the Shenzhong Passage is connected by 32 pipe sections weighing about 80,000 tons and a final joint. At a depth of more than 30 meters, the 80,000-ton standard immersed tube can achieve millimeter-level docking, which is as difficult as the docking of a manned spacecraft and the "Tiangong" space station.
"But it is difficult, but it is more courageous." The construction of this super project demonstrates the strength of the country and the hard work of the builders. A builder once sighed, "This is an exam without difficulty, because it is all difficult." "More than 10,000 builders participated in the construction of the Shenzhen-Zhongshan Corridor. Without their efforts, there would be no "Bay Area Dragon", and there would be no way to talk about "sighing Lingding" becoming "cross-Lingding".
There is a figurative saying that the completion of the Shenzhen-Zhongshan Corridor is to connect the east and west banks of the Pearl River Estuary again after the Hong Kong-Zhuhai-Macao Bridge, and make up for the key "one horizontal" for the main framework of the "A" shaped traffic in the Guangdong-Hong Kong-Macao Greater Bay Area.
What does this key "one horizontal" bring? After the opening of the Shenzhen-Zhongshan Corridor, it only takes half an hour to drive from Shenzhen to Zhongshan. In other words, the construction of the Shenzhong Corridor shortens the geographical distance and shortens the psychological distance.
From a broader perspective, the construction of the Shenzhen-Zhongshan Corridor is of much more significance. The Shenzhen-Zhongshan Corridor cannot be mentioned without mentioning the Guangdong-Hong Kong-Macao Greater Bay Area, and the Guangdong-Hong Kong-Macao Greater Bay Area cannot be mentioned without mentioning an important planning outline - the "Outline Development Plan for the Guangdong-Hong Kong-Macao Greater Bay Area".
In the chapter on "Spatial Layout", the Outline clearly proposes to build a regional economic development axis and form a networked spatial pattern of efficient connections between major cities by relying on the rapid transportation network with high-speed railways, intercity railways and high-grade highways as the main body, as well as port clusters and airport clusters.
The outline also proposes to give better play to the role of the Hong Kong-Zhuhai-Macao Bridge, speed up the construction of important transportation facilities such as the Shenzhen-Zhongshan Corridor and the Shenzhen-Mao Railway, improve the development level of the west bank of the Pearl River, and promote the coordinated development of the east and west coasts. Further, the construction of the Shenzhen-Zhongshan Corridor should not be viewed in isolation, but should be linked to improving the development level of the west bank of the Pearl River, to promoting the coordinated development of the east and west coasts, and to building the Guangdong-Hong Kong-Macao Greater Bay Area.
The Guangdong-Hong Kong-Macao Greater Bay Area is one of the regions with the highest degree of openness and the strongest economic vitality in the mainland, and has an important strategic position in the overall development of the country. The construction of the Guangdong-Hong Kong-Macao Greater Bay Area is of far-reaching significance, for example, it can change the situation that Hong Kong's economic growth lacks sustained and stable support, Macao's economic structure is relatively simple, development resources are limited, and the market economy system of the nine cities in the Pearl River Delta needs to be improved. Another example is the construction of a world-class urban agglomeration, the implementation of the new development concept, the further deepening of reform, the expansion of opening up, and the promotion of the "Belt and Road" construction.
"Bay Area integration, transportation first." From this point of view, the construction of the Hong Kong-Zhuhai-Macao Bridge and the Shenzhen-Zhongshan Corridor, as well as the enhancement of the radiation and driving role of Hong Kong, Macao, Guangzhou and Shenzhen in the development of the surrounding areas, will have a deeper understanding.
"Build a good bridge and pave a concentric road". After the news that the Shenzhong Channel passed the delivery and acceptance, many cities in Guangdong were ready to do a big job. For example, Jiangmen, Guangdong Province, said that the opening of the Shenzhen-Zhongshan Corridor will greatly shorten the traffic distance between the east and west banks of the Pearl River Estuary. Shenzhen-Jiangxi cooperation is an important hand-in-hand across the east and west banks of the Pearl River Estuary, and a cross-regional integrated development to promote the rational flow and optimal allocation of production factors.
"Embrace the Shenzhen-Zhongshan Channel, 'hand in hand' with the three-trillion-level metropolis, and a more dynamic Jiangmen is coming." This kind of imagination will eventually turn from a dream into a reality. Correspondingly, the Shenzhen-Zhongshan Corridor is about to open to traffic, and the Zhongkai (Zhongshan-Kaiping) Expressway, which is the expressway connection line of the Shenzhen-Zhongshan Corridor, will also be opened soon. The Zhongkai Expressway Project is the "seventh horizontal" in the "12 vertical, 8 horizontal, 16 shooting and two rings" of the Guangdong Provincial Expressway Network Plan, passing through Nanlang Street, Torch Development Zone, Dongqu Street, Shaxi Town, Henglan Town, and crossing the Modaomen Waterway into Jiangmen City.
Ling Yunjian's pen is vertical and horizontal. The Shenzhen-Zhongshan Corridor, the key "one horizontal" that is about to be "put on the job", and the "traffic backbone" that crosses the Lingding Ocean, will bring more imagination to the future of the Guangdong-Hong Kong-Macao Greater Bay Area.
