目前世界上用于清淤的机械主要有:1.水力吸泥清淤,又称虹吸排淤装置。此种清淤装置1970年首先在阿尔及利亚色拉河Baugivd 水库上试验成功。这种方法是利用坝上下游水位差,按虹吸原理将泥沙排往下游。输泥管悬挂在库中的浮筒上,其进口端由操作船沿淤积面移动,排出浓度达15%,最大可超过50%,以后又在 Sidimkhammed 水库及我国田 Currently the world for dredging machinery are: 1. Suction dredging, also known as siphon silt device. The dredging plant was first successfully tested on the Baugivd reservoir in the Sera in Algeria in 1970. This method is to use the dam upstream and downstream water level difference, according to the siphon principle to discharge sediment downstream. The dredging pipe is suspended on the pontoon in the warehouse, and its inlet end is moved along the silt surface by the operating vessel to discharge a concentration of 15% and a maximum of over 50%. Later on, the Sidimkhammed Reservoir and our country
