1991年宁波市镇海区10台机械挖泥船,共挖泥35.2万土方,挖河长度达40千米以上,受到了该区干部和农户的好评。他们说:“上几年一到冬季一家一户分河段挖泥,有些农户男女老少齐出动还不够,还要招兵买马来拼凑,既冷又苦。现有机械挖泥,保质、省时、效益高,疏河清淤常不懈,真是太好了。” 据该区骆驼镇试验,机械挖泥比人工挖泥提高工效65倍以上,成本可节约70%以上,而且大大减轻了劳动强度。机械挖泥提高了抗旱排涝能力。同时机械挖泥不需打坝抽水,不影响河运,而且还解决了部分砖瓦厂用土,保护了良田,取得了
In 1991, 10 mechanical dredgers in Zhenhai District of Ningbo City dredged a total of 352,000 earthworks and dredged rivers of more than 40 kilometers in length. They were praised by cadres and farmers in this area. They said: “In the past few years, in the winter, one family of households dredging one by one, some of them were not enough to mobilize men, women, and children, and recruiting troops and horses to piece together both cold and hard work. , High efficiency, Shu dredging often unrelenting, really good. ”According to the town camel test, mechanical dredging than artificial dredging to improve work efficiency more than 65 times, the cost can be saved more than 70%, but also greatly reduce the labor strength. Mechanical dredging improves drought and drainage capacity. Mechanical dredging at the same time do not need to fight dam pumping, does not affect river transport, but also to solve some of the brick mills with soil, protect the fertile land, made
