自1770年荷兰造成第一艘链斗式挖泥船用于疏浚工程以来,机械疏浚事业的发展至今已有200余年的历史。我国最早于1889年开始在黄浦江使用挖泥船施工,1929年江南造船厂造成第一条国产链斗式挖泥船—“海龙号”。建国前后,挖泥船多用于港口、航道疏浚及滩涂造地等,船型多为中小型链斗式、抓斗式和绞吸式挖泥船。水利水电系统 Since the first chain dredger dredged in the Netherlands in 1770 for dredging, the development of mechanical dredging has been more than 200 years old. As early as 1889, China started to use dredgers in the Huangpu River. In 1929, Jiangnan Shipyard created the first domestic chain bucket dredger, “Dragon”. Before and after the founding of the People’s Republic of China, dredgers were mostly used in ports, waterway dredging and land reclamation. Most of them are small and medium-sized chain bucket, grab and cutter suction dredgers. Water conservancy and hydropower system
