一、概述 耙吸式挖泥船是利用泵机通过耙头将水下泥沙挖吸入自备泥舱的自航式挖泥船(图一)。从1903年开始有这种挖泥船至今已有七十余年。我国于1935年从德国进口的“建设”号、于1943年从日本引进的“浚快”、“浚利”号,都属于较大型的自航耙吸式挖 I. Overview Trailing suction dredger is a self-propelled dredger that utilizes a pumping machine to drag underwater sediment into the self-propelled hopper through a rake head (Figure 1). This dredge has been in existence for more than seventy years since 1903. China’s “Construction” imported from Germany in 1935 and “Jun Express” and “Junli” imported from Japan in 1943 all belonged to the larger self-propelled trailing suction excavators
