我国有丰富的水利资源,河流、湖泊、水库、排灌沟渠众多,多年来淤积比较严重。我们对一些地区的中小河道和沟渠的淤积及新渠的开挖工作做了调查。例如江南水网地区中小内河航道因淤积影响航运的畅通;内蒙巴盟灌区和新疆等地的排灌沟渠由于自然淤积和塌坡引起的淤积占总长度的40～85％;三江平原七星河等数条河道需要治理,因此河道和沟渠的清淤与治理工作日趋迫切。为满足这一工作的需要,水利电力部长春机械研究所与江苏省水利建筑工程公司船厂联合研制了SLX Qy-40型液压两栖绞吸式清淤机。(见封四)
China has abundant water conservancy resources, rivers, lakes, reservoirs and irrigation and drainage ditches are numerous, with siltation more serious over the years. We investigated the siltation of small and medium channels and ditches in some areas and the excavation of new ditches. For example, the inland waterways of small and medium inland waterways in the Jiangnan Water Network affected the smooth flow of shipping due to siltation; the siltation caused by natural siltation and slope collapse in the basin irrigation districts of Inner Mongolia and Xinjiang reached 40-85% of the total length; Qixinghe The need for treatment of river courses, dredging and treatment of rivers and ditches is becoming increasingly urgent. In order to meet the needs of this work, Changchun Institute of Hydraulic Machinery and Shipbuilding Co., Ltd., Jiangsu Province, jointly developed a hydraulic SLX Qy-40 amphibious cutter.
