带电更换直线砼杆下(中)节施工方法

本文主要针对输电线路砼杆长期运行,由于受到不平衡张力及自然条件下长期风化作用,使得部分杆段出现老化裂纹现象,如果不能及时处理,会严重影响输电线路安全运行。所以本文提出采用"带电更换砼杆下(中)节"的施工方法,并对带电更换砼杆下(中)节的可行性及采用的设备及工具进行分析计算,以提高带电更换砼杆下(中)节作业的安全性,此作业方法可以实现及时更换砼杆受损的部分,提高了设备可用率,避免了输电线路长时间停电造成的损失,其产生的经济效益和社会效益是重大的。

Replacement of the Low(Middle)Concrete Pole Section in Live-working

After a long-term operation, the aging phenomenon such as crack will appear in some sections of the concrete pole because of the unbalance tension and efflorescence,. If not dealt with properly, it will affect the security of transmission line operation seriously. In this passage, we suggest replacing the low (middle) concrete section in live-working. To improve the safety, we need to analyze the tools of replacing in live-working, estimate the feasibility. In this method, we can achieve to replace the dama...
