张庄入黄闸位于河南省台前县黄河大堤与北金堤交汇处,1966年交付使用。闸门门扇两端用钢丝绳悬吊,6孔闸门共12根钢丝绳,在水下的长度为50多米。由于闸室长年积水,闸门法兰盘下部钢丝绳经常浸在水下及泥沙之中,极易发生腐蚀,削弱承载能力。 张庄间投入运用至1969年,每年在钢丝绳上涂抹黄油4次,下水后黄油很快失效或脱落。1969年～1971年对此方法作了改进,即涂抹黄油后再缠绕一层麻绳,但防腐效果仍不好。 自1972年起,改用棉纱(或棉布)蘸柴油,把钢丝绳上的杂物油腻洗刷干净,再用干的棉纱(或棉布)擦去钢丝绳上的柴油,然后涂抹上新鲜黄油一层,厚2～3毫米;黄油外面再包裹塑料布2～3层,以免黄油被水沙冲磨掉。塑料
Zhangzhuang into the Yellow Gate is located in the county of Henan Province, the Yellow River embankment and the North Jindi Interchange, delivered in 1966. Gates at both ends of the door hanging with a steel wire rope, a total of 12 6-hole steel wire rope in the underwater length of 50 meters. As the sluice chamber for many years of water, the lower gate flange of the rope often immersed in water and sediment, vulnerable to corrosion, weakening the carrying capacity. Zhang Zhuang into operation until 1969, every year in the wire rope smear butter 4 times, the butter soon after the failure or fall off. This method was improved from 1969 to 1971, that is, a layer of hemp rope was applied after the butter was applied, but the preservative effect was still not good. Since 1972, using cotton yarn (or cotton cloth) dipped in diesel oil to clean the wire rope debris greasy, and then use dry cotton yarn (or cotton cloth) to wipe off the diesel wire rope, and then apply a layer of fresh butter, thick 2 ~ 3 mm; plastic wrap outside the butter and then wrapped 2 to 3 layers, so butter is washed away by water and sediment. plastic
