我国各大水系的河道疏浚、湖泊港口治理,多采用挖泥船进行施工,这是人所共知的事实,它不但效率高、单价低、质量好,更重要的是它能完成人力和其他机械不能胜任的水下土石方开采任务。我局自六十年代初组建以来,首先担负了卫河清淤,随后疏浚了马颊河、徒骇河、双龙河,治理了大明湖、洪泽湖、南四湖等几十项工程。所有这些工程都按设计要求,定期保质胜利地完成了任务,为防洪、排涝、治碱、通航作出了贡献。七十年代末我们又从荷兰 IHC 公司引进了海狸大型绞吸式挖泥船。引进的目的是为解决荆江大堤加固,使长江汉水分洪,确保武汉及其下游的安全。这种船舶比较先进,除采用液压传动和操纵外,还有产量计、剖面控制器、定位桩台车以及潜管等设备,同
It is a well-known fact that river dredging and lake harbor management in major water systems of our country are mostly carried out by dredgers. It not only has high efficiency, low unit price and good quality, but more importantly, it can complete manpower and other Machinery can not do the task of underwater rock and stone mining. Since the formation of the bureau in the early 1960s, we have taken over the dredging of the Wei River and dredged the Majia River, Tuhai River and Ssangyong River and dredged dozens of projects such as the Daming Lake, Hongze Lake and Nansi Lake. All of these projects according to the design requirements, the periodic durability of the successful completion of the task, for flood control, waterlogging, alkali treatment, navigation made a contribution. In the late seventies we again introduced the Beaver large cutter suction dredger from IHC Netherlands. The purpose of the introduction is to solve the reinforcement of the Jingjiang River embankment and to flood the Han River and the Yangtze River to ensure the safety of Wuhan and its downstream areas. This ship is more advanced, in addition to the use of hydraulic transmission and control, as well as production meters, profile controllers, positioning pile trolley and submarine and other equipment,
