In recent years, it has created a number of China's first port-building technology in China, and has successively delivered a new report on technological innovation, adding a new chapter to its scientific and technological achievements. The technology of "new structure of blind-type sheet pile terminal" developed by the company has improved the berth level of Jingtang Port from 20,000 tons to 100,000 tons, breaking the traditional textbook in the field of hydraulic construction. The conclusion that the characteristics are only suitable for the construction of small and medium-sized wharfs makes the dream of building a large-scale deep-water wharf of 100,000-ton and above in the sheet pile terminal a reality.
The construction of the blind-type sheet pile wharf does not require the large replacement of the prefabricated plant and the earthwork. The construction process is simple, the speed is fast, and the quality is easy to guarantee. At the same time, under the foundation conditions suitable for the construction of sheet pile wharf, the construction cost is 10% to 30% less than other structures. The completion of the large-tonnage sheet pile wharf has achieved a major breakthrough in China's port construction technology, opening up broad prospects for the application of sheet pile structure wharf.
The completion of the 100,000-ton berth has solved the "bottleneck" that restricts the development of Jingtang Port, and laid a solid foundation for the Jingtang Port to reach the billion-ton port. Tangshan Port subsequently built several large berths in the Jingtang Port Area. At the same time, it extended this new structure to the Caofeidian Port Area, adding a heavy weight to the early realization of the construction goal of the Tangshan Port.
In 2006, the two technologies of “new structure of semi-blind sheet pile terminal†and “new structure of full curtain type sheet pile terminal†were granted the national utility model patent. The results of the “Research and Development of Complete Structure Technology for Deep Water Sheet Pile Terminal†were appraised by the results of the China Water Transport Construction Industry Association. It is believed that the achievement has reached the international leading level in general and won the Special Award of Science and Technology Award of China Water Transport Construction Industry Association in 2011. .
In addition, CCCC First Aviation Institute has also pioneered the “semi-circular caisson†in recent years, developed and applied the new structure of in-line vacuum preloading and strengthening soft soil foundation, and the application of key technologies for the design of corrosive silty coastal port, offshore. Deepwater port waves – breakwaters – research on ground interaction issues.
At the same time, in the design of Tianjin Port Channel, CCCC First Airways proposed the concept of “complex channel†for the first time in China, effectively increasing the passage capacity of the channel, and achieving navigation capacity for Tianjin Port and achieving 700 million tons of throughput capacity by 2020. Provide technical support.
The compound channel plan is to dig a one-way channel of 10,000-ton ships parallel to the main channel on the north and south sides of the main channel, and go north and south to divert the large and small ships. Thus, the main channel and the 10,000-ton waterway on both sides of the north and south constitute a complex channel. This not only facilitates the entry and exit of the 10,000-ton and below ships from both sides of the one-way channel, but also leaves only 30% of the main channel with more than 10,000-ton ships, greatly reducing the navigation density of the main channel.
It is reported that since 1978, Yihang Institute has won 297 engineering project awards and technical achievement awards, and only 83 national and provincial awards. At present, the company has 28 effective national patents, and 27 technical achievements have been selected as new records for Chinese enterprises. At the same time, it has presided over the preparation of nearly 100 national standards and industry norms.
