Recently, the Ministry of Transport's “Eleventh Five-Year Plan” major science and technology project – “Key Technology Research on Offshore Deepwater Port Construction” passed the acceptance test. The project has laid a solid theoretical and technical foundation for the development of China's port construction to offshore deep water, and has broad application prospects in offshore deep-water ports, trans-sea passages and marine engineering.
It is reported that the project was established in 2006, led by China Communications Construction Co., Ltd., and concentrated on the strengths of 25 units of research institutes, universities, design and construction in the domestic water transport industry. 100 million yuan is the largest water transport transportation technology project since the founding of New China.
For the first time, the project proposed the concept of suspended equilibrium sediment concentration and sedimentary equilibrium sediment concentration. The port facilities of soft ground based on the construction of ports on offshore islands, port construction on silty coast, durability of offshore concrete and waves There are many independent innovations in key technologies such as construction and offshore construction equipment under the conditions of deep water and big waves. For the first time, the project has established a life prediction model that is consistent with the typical offshore concrete structure in China. It has also developed a new type of deepwater riprap leveling ship, which realizes the riprap, leveling and quality inspection of the gravity type hydraulic structure underwater riprap bed. The integrated mechanized leveling operation fills the blank of China's deepwater mechanization leveling technology, and has developed a complete set of underwater compacted sand pile construction equipment, construction technology and construction management software.
