Chinese technology!The 6000 -ton structure is accurately inserted into the bottom of the sea to complete the penetration of the Hong Kong -Zhuhai -Macao Bridge Underwater Tunnel

Hong Kong -Zhuhai -Macao Bridge

The total length of the Hong Kong -Zhuhai -Macao Bridge with a total length of 5.6 kilometers is completed. It is a perfect proof of Chinese technology. The 6,000 -ton structure is accurately inserted into the sea floor and allows the bridge to be completed. This not only further strengthened the connection between regional, but also provided great convenience for China's surrounding economic and trade activities.

The Hong Kong -Zhuhai -Macao Underwater Bridge is currently the world's longest road sinking tunnel and the only deep -buried sink tunnel. The Hong Kong -Zhuhai -Macao Bridge started construction from the end of December 2009. In September 2016, the main bridge and submarine tunnel of the bridge were connected. By 2017, the main project of the Hong Kong -Zhuhai -Macao Bridge achieved the entire line. Since then, it has the conditions for traffic, which has greatly shortened the time between exchanges between several areas, and also provided operating channels for the Pearl River Pass channel. Among them, the Hong Kong -Zhuhai -Macao Bridge Underwater Tunnel can be said to be the most difficult underwater tunnel project worldwide. However, Chinese infrastructure has still overcome difficulties and perfectly completed the project.

So what are the great difficulties in the process of building the Hong Kong -Zhuhai -Macao Bridge? First of all, the underwater environment increases the construction difficulty of the submarine tunnel. The bottom of the sea is basically soft. It is impossible to fix the sinking pipe and 6000 tons of connecting structures in the soft soil. Therefore, before the construction of the tunnel, the soft soil on the bottom of the sea should be reinforced to its extent to be able to withstand the weight of the joint structure and the weight of sinking pipes, and it is also necessary to ensure that there will be no sinking problems in the future. In this regard, Chinese infrastructure engineers have used a method that have never been used in China to use many sand piles into hard soils under the seabed 40 meters full of silt, and solve the problem of unable to fix the joints and sinking pipes on the bottom of the sea. It laid a solid foundation for the continued construction of the tunnel in the future, so that subsequent projects can be carried out smoothly. This method of infrastructure in China has created a precedent for domestic infrastructure. Even if it is a very rare operation in the world, the Chinese infrastructure gives full play to its wisdom and perfectly overcome this problem with its superb construction technology. Essence

Secondly, the construction of tunnels under 40 meters itself is a big difficulty. Because during the construction of the tunnel, the sinking tunnel needs to be spliced, and the tunnel splicing project has great requirements for technical requirements, and there must be no errors. Once the stitching is wrong, it will not only cause the tunnel operation to be directly paralyzed, but also will also be paralyzed. Make the sea water into the tunnel and put the traversing vehicles in a huge danger, causing great casualties and losses. Therefore, the tunnel splicing project of the Hong Kong -Zhuhai -Macao Bridge must be dripped without leakage. It must rely on high -end construction technology and advanced construction management. All parties cooperate with each other and meticulous to ensure that the tunnel will not seep in the end. This has very high requirements for the overall technical level of China's infrastructure, and it is not upset for expectations and solves another problem with its own strength.

China Infrastructure uses its superb technologies and capabilities, which not only has built many worldwide projects for China. The construction of infrastructure in ports overseas is also the top spot, and the strength of many countries will be convinced by strength. For so many years, Chinese infrastructure has left profound marks at home and abroad. Needless to say, the domestic Hong Kong -Zhuhai -Macao Bridge Underwater Tunnel is called "the best bridge in the world" by the Jiaozhou Bay Bridge. The Port of Gwadar built in Pakistan, the Port Castle Castle of Colombo, etc. built in Sri Lanka, etc., is unbearable, and China has also won the title of "Infrastructure Magic" because of its excellent infrastructure technology. Until now, many countries have actively sought cooperation with China, because these countries have seen the strength of Chinese infrastructure and have greatly trust the level of Chinese infrastructure. In the future, China's infrastructure will also move to the world with its own technology and strength to help more countries build high -quality engineering projects and promote common development.
