水(shui)泥電線桿的焊接要求(qiu)：  

1、首(shou)先兩節(jie)桿對接(jie)調直(zhi)，將水泥(ni)電線桿下節(jie)放置平整的(de)地(di)面，然(ran)后對接(jie)上節(jie)對直(zhi)。  

2、其次焊(han)(han)接固(gu)(gu)定(ding)，在水泥電線桿調直以(yi)后按照焊(han)(han)接位置平(ping)均打(da)點固(gu)(gu)定(ding)，在整個焊(han)(han)接法蘭焊(han)(han)接三(san)個點進行固(gu)(gu)定(ding)，打(da)點固(gu)(gu)定(ding)完(wan)成開始校(xiao)直，用水平(ping)儀檢測(ce)電線桿是(shi)否對直，在焊(han)(han)接時主要的注意的問題(ti)就(jiu)是(shi)焊(han)(han)接工序(xu)以(yi)及(ji)要點。  

3、焊(han)接(jie)水泥(ni)電(dian)線(xian)桿(gan)(gan)，在焊(han)接(jie)時注意(yi)焊(han)點均勻，整個(ge)焊(han)接(jie)需要三(san)遍(bian)焊(han)接(jie)方可完成，涂刷除銹(xiu)漆，除去焊(han)接(jie)位置銹(xiu)斑，涂刷防腐漆，電(dian)線(xian)桿(gan)(gan)注意(yi)用于高壓電(dian)力(li)架設，如(ru)果(guo)焊(han)接(jie)不牢固導(dao)致電(dian)線(xian)桿(gan)(gan)拉(la)力(li)減弱(ruo)強度減小從而造成損壞。

  4、偷工減料后果(guo)及影響： 

在生產水(shui)(shui)泥電線(xian)(xian)(xian)(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)(gan)是減(jian)(jian)(jian)少材料(liao)(liao)(liao)使(shi)(shi)用量，水(shui)(shui)泥、鋼筋、內外(wai)環，一(yi)根電線(xian)(xian)(xian)(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)(gan)可以減(jian)(jian)(jian)少20元成本，偷工(gong)(gong)減(jian)(jian)(jian)料(liao)(liao)(liao)導致(zhi)后(hou)果，不(bu)達標電線(xian)(xian)(xian)(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)(gan)在安裝(zhuang)使(shi)(shi)用上危險極(ji)大(da)，在架(jia)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)、緊(jin)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)是容(rong)易(yi)拉(la)斷(duan)電線(xian)(xian)(xian)(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)(gan)。偷工(gong)(gong)減(jian)(jian)(jian)料(liao)(liao)(liao)的(de)電線(xian)(xian)(xian)(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)(gan)在運輸(shu)上容(rong)易(yi)壓(ya)裂，壓(ya)碎，偷工(gong)(gong)減(jian)(jian)(jian)料(liao)(liao)(liao)的(de)電線(xian)(xian)(xian)(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)(gan)強度(du)差距很大(da)，導致(zhi)運輸(shu)壓(ya)碎、緊(jin)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)拉(la)斷(duan)事情不(bu)在期數。偷工(gong)(gong)減(jian)(jian)(jian)料(liao)(liao)(liao)的(de)電線(xian)(xian)(xian)(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)(gan)使(shi)(shi)用年限較短，減(jian)(jian)(jian)少水(shui)(shui)泥使(shi)(shi)用量導致(zhi)水(shui)(shui)泥電線(xian)(xian)(xian)(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)(gan)強度(du)大(da)大(da)降低，表(biao)面脫皮，使(shi)(shi)用年限減(jian)(jian)(jian)少，熱脹冷(leng)縮(suo)；所以夏天架(jia)設(she)電線(xian)(xian)(xian)(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)(gan)時(shi)，要留出足(zu)夠的(de)余(yu)量，以免冬天時(shi)電線(xian)(xian)(xian)(xian)(xian)(xian)(xian)收(shou)縮(suo)而拉(la)斷(duan)電線(xian)(xian)(xian)(xian)(xian)(xian)(xian)或(huo)者拉(la)倒電線(xian)(xian)(xian)(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)(gan)。  

三、水泥電線桿變(bian)彎的(de)預防方法  

1、采購水泥電線(xian)(xian)(xian)桿時，應嚴(yan)把質(zhi)量關，對電線(xian)(xian)(xian)桿做基本(ben)的(de)檢測，主要是看出廠的(de)電線(xian)(xian)(xian)桿表面是否(fou)有裂紋，電線(xian)(xian)(xian)桿內壁是否(fou)平整(zheng)，電線(xian)(xian)(xian)桿整(zheng)體(ti)是否(fou)垂直(zhi)，還有就(jiu)是看下露(lu)出的(de)鋼筋(jin)是否(fou)已經生銹或容易掰彎。  

2、電線(xian)桿(gan)在安裝時，電線(xian)桿(gan)底部深度應保證(zheng)在1米左右，防(fang)止(zhi)電線(xian)桿(gan)歪倒，另(ling)外(wai)安裝好以后，在嚴(yan)寒(han)季節應對使用捆扎的草裙(qun)圍(wei)繞電線(xian)桿(gan)周圍(wei)，防(fang)止(zhi)因為嚴(yan)寒(han)出(chu)現裂紋。
