China applies the earliest artificial dredging method to dig the canal, dredge the river, communicate the water system to develop shipping, flood drainage, irrigation civilization. It can be traced back to the great yu river control, the spring and autumn period and the warring states began the great project of canal excavation, some of which still play an important role today, such as DUJIANGYAN in sichuan irrigation county, lingqu in guangxi, beijing-hangzhou grand canal and so on. The excavation of the qin dynasty chief bing and his son built dujiangyan project from its design ideas, scale, function, and built weir "" deep clean out beach, low maintenance principle shows step of the scientific level, not only for the countries all over the world nearly as hard, also for today's science, the treasure of the dujiangyan project until now also play an important role in sichuan plain agricultural irrigation.
From dredging tools, as early as the song dynasty invented the "dredging harrow", "iron broom", "scraper", "dredging river iron thorn" and other disturbance dredging maintenance tools. These advanced tools of production were not yet available in Europe.
The long and backward feudal society, especially the modern semi-feudal and semi-colonial society, fundamentally hindered the development of productive forces. China's science and technology changed from advanced to backward.
After the founding of new China in 1949, dredging, like other economic fronts, began to recover and expand. Shanghai, tianjin, guangzhou and other ports have been successfully dredged to ensure the normal operation of ports across the country. Tanggu new port, built in 1952, is a 10,000-ton channel and harbor pool dug out of the silt. The methods of regulation, dredging and reef blasting have been adopted in sichuan river to make the dangerous, urgent and shallow water roads into sichuan become thoroughgoing. Port construction, especially the large-scale construction of coastal deep water port, has put forward unprecedented new requirements for dredging, and traffic dredging has been developed rapidly in China. Since 1973, the navigation bureau under the ministry of communications has introduced a large number of advanced dredgers in the short period of several years, especially the large rake suction vessels and winder suction vessels suitable for operation in the estuary and coastal areas, which have rapidly expanded the dredging project and scale and ensured the smooth completion and production of the coastal port construction. In 1975, the successful opening of the artificial channel into the sea at the changjiang estuary of Shanghai harbor and its subsequent successful maintenance marked a new period in which the dredging technology level of China began to improve and surpass the international advanced level. China's dredging capacity has jumped to the front of the world. After 1981, we successfully entered the international dredging market, more than ten years, has achieved a good reputation.
