为探索一条防治根石走失的新途径,河南黄河河务局过去曾在马渡险工85坝一个附垛上修建了一个铅丝网罩石垛,其原理与鱼网相似。但是对九堡下延铅丝笼沉排坝进行的解剖分析表明:铅丝在使用7～8年后就发生严重腐蚀,失去了其应有的作用。为解决铅丝腐蚀问题,河南萧河河务局有关技术人员在查阅国内外水利工程有关资料和对水利工程进行现场考察的基础上,于1999年在马渡险工22～39坝之间(相应黄河南岸大堤桩号24+000～25+000)的13个坝垛上,
In order to explore a new way to prevent the loss of roots and stones, Henan Yellow River River Bureau in the past had an attached to the Mudou 85 dam on the construction of a wire mesh cover stack, the principle and the net similar. However, the anatomical analysis of the Jiubao lower lead wire cage sedimentation dam shows that the lead wire has suffered serious corrosion after 7 to 8 years of use, losing its proper function. In order to solve the problem of corrosion of lead wire, relevant technicians from Henan Xiaohe River Bureau, on the basis of consulting the domestic and foreign water conservancy projects and on-site inspection of water conservancy projects, South Bank embankment station 24 + 000 ~ 25 + 000) of the 13 dams,
