輸配電線路的架起是電網建造中的一部分，而水泥桿的排桿、對接與焊接是線路施工中一項重要的生產流程，也是關系到整個工程施工質量、施工進度的重要環節。      

架空電力線路建造施工中，直線桿通常選用水泥電桿，運用現澆混凝土套筒根底與電桿銜接，它的長處是強度高，經久耐用，占地少，便利農業機械化耕耘。跟著社 會經濟的開展，人民生活水平的不斷進步，當前鄉村房子的樓層通常為2~3層。電力線路與房子及“三線”的穿插跨過不可避免，這就需求進步電力線路桿塔高 度，如今直線桿已遍及運用24m、27m、30m水泥桿，水泥桿直徑大，全體分量到達7~8t，有必要分節加工，每棵電桿的接頭數量少則3個，多則5個，而 焊接質量的好壞將直接影響到電力線路安全運轉。

從水泥電桿裂紋發生以及發展的原因來看，進行及早的處理，阻止或減緩裂紋發展是非常重要的。總的來講，可對裂紋進行修補或換桿。修補時應遵循封閉性、耐侯性、高強長效的原則，環氧樹脂經過合理配方能夠滿足要求，對于裂紋面積大、裂紋嚴重的水泥電桿可分段更換或全桿更換。 

鋼(gang)筋(jin)混(hun)凝土打樁法(fa) 一般桿根(gen)部位彎應力比(bi)較(jiao)大，而且(qie)接近土壤與潮氣，內部可能存水(shui)、結冰，是容易(yi)產生裂紋的(de)部位，裂紋發展也比(bi)較(jiao)快。如果線(xian)路的(de)下(xia)叉梁抱箍安裝位置(zhi)比(bi)較(jiao)靠上(shang)，可以環繞桿根(gen)澆鑄鋼(gang)筋(jin)混(hun)凝土形成護樁。護樁厚度150～200 mm，地(di)面以下(xia)0.5 m左右，地(di)面以上(shang)高(gao)度不超過(guo)1.5 m，否則(ze)影響使用腳(jiao)扣上(shang)桿。

水(shui)泥電線桿的焊接要求：  

1、首先兩節(jie)桿(gan)(gan)對接調直，將(jiang)水泥電線(xian)桿(gan)(gan)下節(jie)放(fang)置平整的地面，然后對接上節(jie)對直。  

2、其次焊(han)(han)接固(gu)(gu)定(ding)，在水(shui)泥電線(xian)桿調直以后按(an)照焊(han)(han)接位置(zhi)平(ping)均打點(dian)固(gu)(gu)定(ding)，在整個焊(han)(han)接法蘭焊(han)(han)接三個點(dian)進(jin)行固(gu)(gu)定(ding)，打點(dian)固(gu)(gu)定(ding)完(wan)成開始校直，用水(shui)平(ping)儀檢測電線(xian)桿是(shi)否對直，在焊(han)(han)接時主要的注意的問題就是(shi)焊(han)(han)接工序(xu)以及要點(dian)。  

3、焊(han)接水泥(ni)電線(xian)桿(gan)，在焊(han)接時注意(yi)(yi)焊(han)點均勻，整個焊(han)接需(xu)要三遍(bian)焊(han)接方可完成，涂刷除銹漆，除去焊(han)接位置(zhi)銹斑(ban)，涂刷防腐漆，電線(xian)桿(gan)注意(yi)(yi)用于高壓電力架(jia)設，如果焊(han)接不牢固(gu)導(dao)致電線(xian)桿(gan)拉力減弱強度減小(xiao)從而造成損壞。

  4、偷工減料后果及影(ying)響： 

在生產水(shui)泥(ni)(ni)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)桿(gan)是(shi)減(jian)(jian)少(shao)(shao)材料使用量，水(shui)泥(ni)(ni)、鋼(gang)筋(jin)、內外環(huan)，一根電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)桿(gan)可(ke)以減(jian)(jian)少(shao)(shao)20元成本，偷(tou)工(gong)減(jian)(jian)料導(dao)致(zhi)后果(guo)，不(bu)達標(biao)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)桿(gan)在安(an)裝使用上危險(xian)極大(da)，在架(jia)線(xian)(xian)(xian)(xian)(xian)、緊(jin)線(xian)(xian)(xian)(xian)(xian)是(shi)容(rong)易拉斷電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)桿(gan)。偷(tou)工(gong)減(jian)(jian)料的電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)桿(gan)在運輸(shu)上容(rong)易壓裂，壓碎，偷(tou)工(gong)減(jian)(jian)料的電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)桿(gan)強(qiang)(qiang)度差距很(hen)大(da)，導(dao)致(zhi)運輸(shu)壓碎、緊(jin)線(xian)(xian)(xian)(xian)(xian)拉斷事(shi)情不(bu)在期數。偷(tou)工(gong)減(jian)(jian)料的電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)桿(gan)使用年限較短，減(jian)(jian)少(shao)(shao)水(shui)泥(ni)(ni)使用量導(dao)致(zhi)水(shui)泥(ni)(ni)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)桿(gan)強(qiang)(qiang)度大(da)大(da)降(jiang)低，表面脫皮，使用年限減(jian)(jian)少(shao)(shao)，熱脹冷(leng)縮(suo)(suo)；所(suo)以夏天架(jia)設電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)桿(gan)時，要留出(chu)足夠的余量，以免冬天時電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)收縮(suo)(suo)而拉斷電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)或者拉倒電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)桿(gan)。
