清淤是农田基本建设的重要环节。据调查,我国南北方的灌区和低洼易涝地区,每隔1～3年,就要清淤一次。而目前的清淤工作基本上还是靠人工锹挖肩担,劳动强度很大,效率很低,一般每个劳力每天只能清淤2～4方土,每年用于清淤的劳动量是非常大的。我省辽中县每年就要动用大约450万个工日清淤,与“三秋”和其它农田基本建设项目争工争时。因此,随着农业学大寨运动的深入发展,农田排灌面积的不断增加,迫切需要解决清淤机械化问题。 Dredging is an important part of farmland construction. According to the survey, irrigated areas in the north and south of our country and low-lying flood-prone areas are dredged once every 1 to 3 years. At present, the dredging work basically still depends on shoulder shoveling by artificial spade, so the labor intensity is very high and the efficiency is very low. Generally, each labor force can only dredge 2 to 4 earths per day, and the annual amount of labor for dredging is very large big. Liaozhong County in our province will spend about 4.5 million man-days of dredging every year to fight against the “Three Autumn” and other farmland infrastructural projects. Therefore, with the deepening development of agricultural science Dazhai movement, increasing irrigation and drainage area of ​​farmland, there is an urgent need to solve the mechanization of dredging.
