The picture shows the artificial island that was initially successfully filled.
As China moved the world's largest eight-way vibrator onto the field, it knocked the 550-ton giant offshore round steel drum into the seabed. This process does not allow for any loss. So what is it that makes China have to carry out such complicated engineering steps?

As a superpower, China will obviously not use the world’s largest eight-way vibrator to lift a large steel structure weighing up to 550 tons without any necessity. The cylinder is directly knocked under the seabed , because this action is unlikely to promote China's economic development. It is obvious that these large steel cylinders, which weigh up to 550 tons, are designed to target certain pedestrian paths or water surfaces. Buildings are specially designed and built on foundations.

In fact, these steel cylinders are specially customized and produced for the Hong Kong-Zhuhai-Macao Bridge. As long as these steel cylinders have a diameter of up to 22 meters and a height of up to 50 meters Steel cylinders are inserted directly into the seabed according to a predetermined plan, and then enough soil is filled between these steel cylinders. Then China can use these super-large steel cylinders to control the soil and water loss caused by the artificial island landfill process. Block, so that China can complete the construction of the east and west artificial islands of the Hong Kong-Zhuhai-Macao Bridge as quickly as possible.
But it is not easy for China to come up with and realize the construction plan of this artificial island. As mentioned before, there are huge challenges in getting the construction of artificial islands in perfect condition. The diameter and depth of the steel columns must be inserted exactly where they should be. As long as the difference from the planned target is more than two centimeters, the installation of this steel column will fail. Therefore, if you want to complete Such installation work not only requires high demands on China's production and construction capabilities, but also ensures that China can produce large round steel pipes that meet the requirements and have sufficient strength, as well as super-high-speed steel pipes that can lift these round steel pipes and install them at designated locations. Large hoisting mechanisms also require China to have engineers with sufficient skills and a high-precision positioning system to ensure that these steel columns can be installed accurately where they should be installed.

Otherwise, after the hoisting of these steel columns was completed, people discovered that they were not installed in the correct position, and wanted to rework or pull out the heights and re-install them. Inserting it is very difficult; in addition, China is building artificial islands in the ocean, rather than the past land reclamation work of tidal flats, and wants to turn these land enclosed by highways into real artificial islands. , China also needs to use some of its special skills in the process of reclamation and island building to ensure that the two artificial islands built for the Hong Kong-Zhuhai-Macao Bridge can be successfully completed.
Therefore, this time the construction of the two artificial islands of the Hong Kong-Zhuhai-Macao Bridge is not an easy task even for a superpower like China. If China had not already had a lot of experience in reclamation and island building, even today China is a big industrial country, and it is also an industrial power. If you want to build these two artificial islands for the Hong Kong-Zhuhai-Macao Bridge, you may have to pay a certain price.
