动力牵引高壩运土卷扬机高壩运土卷扬机,是水利施工中的一个革命创举。它有效地解决了运土上高壩的困难;为水利施工实现机械化做出了榜样。它的优点是:适用范围广,不受地形道路限制,具有升高、下坡、跨河、越岭的性能,造价低、操作易、工效高。一部卷扬机以十六人操作计算,每日能运土三百九十公方,平均每人工效为二十四点三公方,比人推(由壩脚到壩顶)提高工效二十倍以上。紫云山水库全面推行高壩运土卷扬机后,上壩人数减少一半,工程可以提前一年建成。
Power Traction High Dam Earth Hoist High Dam Earth Hoist, is a revolution in water conservancy construction. It effectively solves the difficulties of transporting high dam on the earth and sets an example for the mechanization of water conservancy construction. Its advantages are: wide range of applications, not limited by terrain roads, with the rise, downhill, across the river, the performance of the ridge, low cost, easy operation, high efficiency. A winch was operated by 16 persons and was able to carry 390 kilometers of earthwork per day. The average manpower per worker was 24.3 kilometers, which was 20 times more effective than pushing (from dam feet to crest) Times more. Ziyunshan reservoir full implementation of high-dam soil hoist, the dam reduced by half the number of people, the project can be completed one year in advance.
