拉(la)线(xian)(xian)(xian)棒是(shi)指(zhi)将拉(la)线(xian)(xian)(xian)连接(jie)(jie)到地(di)锚上(shang)的(de)(de)杆(gan)件(jian)或其他金属部件(jian)。许多(duo)(duo)输电线(xian)(xian)(xian)路杆(gan)塔处于(yu)水田(tian)或湿地(di)中，水质、土(tu)质污染日(ri)趋严重(zhong)，致使(shi)越来越多(duo)(duo)的(de)(de)杆(gan)塔接(jie)(jie)地(di)引下线(xian)(xian)(xian)及拉(la)线(xian)(xian)(xian)棒腐蚀(shi)严重(zhong)，无(wu)(wu)法(fa)达到有效的(de)(de)使(shi)用寿(shou)命，从而(er)导(dao)致接(jie)(jie)地(di)电阻无(wu)(wu)法(fa)保证(zheng)，雷击跳闸率(lv)增高，拉(la)线(xian)(xian)(xian)杆(gan)稳定性下降，严重(zhong)威协线(xian)(xian)(xian)路的(de)(de)安全运行。

随(sui)着(zhe)电力事业的飞速发展(zhan)，输(shu)电线路(lu)杆(gan)塔的使用(yong)(yong)(yong)日益增(zeng)多(duo)，但由于江南水(shui)乡水(shui)域及各种湿(shi)(shi)地(di)(di)(di)(di)面积有(you)536平(ping)方(fang)公里，占全市土地(di)(di)(di)(di)面积的11%，还有(you)大面积的水(shui)田。许多(duo)输(shu)电线路(lu)杆(gan)塔处于水(shui)田或湿(shi)(shi)地(di)(di)(di)(di)中，水(shui)质、土质污(wu)染日趋严(yan)重，致使越来(lai)(lai)越多(duo)的杆(gan)塔接地(di)(di)(di)(di)引下线及拉线棒腐(fu)蚀严(yan)重，无(wu)法达到(dao)有(you)效的使用(yong)(yong)(yong)寿(shou)命，从而(er)导(dao)致接地(di)(di)(di)(di)电阻无(wu)法保证，雷击跳闸率增(zeng)高(gao)，拉线杆(gan)稳定(ding)性(xing)下降，严(yan)重威(wei)协线路(lu)的安全运行。同时随(sui)着(zhe)政(zheng)策(ce)处理难度的增(zeng)加，线路(lu)的维修(xiu)(xiu)费用(yong)(yong)(yong)每年耗费巨大。通过分析(xi)发现，在施(shi)工阶(jie)段做好(hao)(hao)相应的防(fang)护措(cuo)施(shi)是解决后续(xu)日常维修(xiu)(xiu)和维修(xiu)(xiu)带来(lai)(lai)的青(qing)苗赔偿费用(yong)(yong)(yong)、人工费用(yong)(yong)(yong)等一(yi)系列问题最好(hao)(hao)的途径。
