In 1966, China imported dredgers from abroad, a 4-ton gold, and now, how good are these new island-making artifacts developed by China Xue shame? Now that China's newly developed reclamation artifacts take only one week, or 7 days, to build an island, what is the reason why China is so serious about the development of dredgers? Dredgers are responsible for dredging the silt of waterways and rivers so that other ships can pass smoothly. It is also a sharp weapon for blowing sand and reclaiming the sea. There are types of suction dredgers, rake suction dredgers and so on. The smooth flow of the river is all dependent on dredgers.

In 2013 and 2015, China's latest dredger, The Sky Whale, operated in the South China Sea for more than two hundred days, blowing in 10 million cubic meters of mud and creating several islands, and this super dredger can not only dig mud, even if the underwater mud is mixed with coral reefs or rocks, it can also be dug up correctly, and they can be crushed into fine sand mixed in the mud and blown out together. And this is the fundamental reason why dredgers such as the Celestial Whale have also become famous in the mouths of Western countries.

If the Tian whale and the Tiankun can use their excavation capacity of 4500 cubic meters per 6000 cubic meters per hour to blow and fill an island the size of a football field in a week, then the "New Haixu" built by China, which uses all the power to blow and fill the work and gives up its self-navigation ability, has more powerful performance than the Tian whale and the Tiankun combined: this super dredging boat with 3 mud pumps and a flow rate of up to 20,000 cubic meters per hour. It only takes an hour to raise an area the size of the same football field by 3 meters. If the water depth is relatively shallow, it may take 1 day to complete the blowing and filling of this island the size of a football field. If you want to do good things, you must first use your tools, and because China has so many powerful dredgers, you can have such a strong performance in the reclamation and land reclamation project and the port dredging project, you don't see, the construction of Huanghua Port, China only took 11 months, this originally piled up silt small river beach finally became a deep-water port that can berth 200,000 tons of large ships, the dredging project of Tianjin Port is as high as 1.1 billion cubic meters, so that China can not only dig out a length of 47 kilometers, a water depth of 21 meters, The excellent waterway with a width of nearly 800 meters also provides 100 square kilometers of new land for Tianjin New Area.

Moreover, today's Chinese dredger design and production system can not only serve the country, but also provide strong design and production capacity for other countries: the Netherlands' top rake suction dredger "BONNY RIVER" is designed and manufactured by China for the Netherlands, and China's domestic dredger technology breakthrough at the same time, the related design and production industries can also get the corresponding technical and market support, thus promoting China's special shipbuilding industry also to achieve great progress. With the gradual growth of China's economy and the improvement of the demand for marine environment development, China's demand for dredgers will become higher and higher, and China's demand for dredgers will become larger and larger in the future.
