On November 28, 2023, the Shenzhen-China Channel undersea Tunnel was successfully completed, which is the world's widest undersea tunnel with a length of about 6.8 kilometers. The construction of the tunnel was unprecedented and was constructed using the "immersed tube method", consisting of 32 pipe sections and one final joint, each weighing tens of thousands of tons. In the construction process, it is necessary to dig the base trough in the seabed, lay gravel, etc., these work require superb skills and fine operation, which can be said to be "submarine embroidery".

In the process of sinking tube docking, 32 sinking tubes weighing 80,000 tons need to be precisely connected together, and the docking accuracy needs to reach the millimeter level, which requires very superb technology and precise operation. In order to achieve this goal, the builders have adopted a variety of intelligent manufacturing technologies, such as automated monitoring, data acquisition, etc., which run through the entire construction process and constantly refresh the world record.

The construction of the Shenzhen-China Corridor is not only an important infrastructure construction project, but also a representative project to demonstrate national strength and scientific and technological innovation. The completion of this tunnel will not only set a new benchmark for the traffic construction in our country, but also provide strong support for future traffic development. In this major country project, we have seen the hard work and wisdom of the builders, let us praise their hard work and excellent achievements! Editor/Xu Shengpeng
