從水(shui)泥電桿裂(lie)紋(wen)發(fa)生以(yi)及發(fa)展的(de)原(yuan)因來(lai)看，進(jin)行及早的(de)處理，阻止(zhi)或減緩裂(lie)紋(wen)發(fa)展是非常重要的(de)。總的(de)來(lai)講，可對(dui)(dui)裂(lie)紋(wen)進(jin)行修補(bu)或換桿。修補(bu)時應遵(zun)循封閉性、耐侯性、高強長(chang)效的(de)原(yuan)則，環氧樹脂經(jing)過合理配(pei)方能夠滿足要求，對(dui)(dui)于裂(lie)紋(wen)面積大、裂(lie)紋(wen)嚴重的(de)水(shui)泥電桿可分段更(geng)(geng)換或全桿更(geng)(geng)換。

鋼(gang)(gang)筋混凝(ning)土(tu)打樁法 一般桿(gan)(gan)根(gen)部(bu)位彎應(ying)力比(bi)(bi)較大，而且接近土(tu)壤與潮(chao)氣，內部(bu)可能(neng)存水、結冰，是(shi)容易產生裂(lie)(lie)紋的(de)(de)部(bu)位，裂(lie)(lie)紋發展也比(bi)(bi)較快。如果線路的(de)(de)下(xia)(xia)叉(cha)梁抱箍(gu)安裝位置比(bi)(bi)較靠上(shang)，可以(yi)環(huan)繞桿(gan)(gan)根(gen)澆鑄鋼(gang)(gang)筋混凝(ning)土(tu)形成(cheng)護(hu)樁。護(hu)樁厚(hou)度150～200 mm，地面(mian)(mian)以(yi)下(xia)(xia)0.5 m左(zuo)右，14米部(bu)分預應(ying)力混凝(ning)土(tu)電(dian)桿(gan)(gan)供(gong)應(ying)商(shang)，地面(mian)(mian)以(yi)上(shang)高度不超(chao)過1.5 m，否則(ze)影(ying)響使用(yong)腳扣上(shang)桿(gan)(gan)。

水(shui)(shui)泥電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)分為預應力(li) 水(shui)(shui)泥電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)和(he)非預應力(li)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)兩(liang)種，通常制(zhi)作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)為電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)鋼(gang)筋加工及鋼(gang)筋籠的(de)制(zhi)作(zuo)(zuo)，鋼(gang)筋的(de)冷拔，堵截曲折(zhe)和(he)綁(bang)扎等。電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)混(hun)凝(ning)土(tu)(tu)配料和(he)然后(hou)對(dui)制(zhi)作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)的(de)資料進(jin)行離(li)心(xin)成型(xing)(xing)，轟動(dong)拌和(he)制(zhi)作(zuo)(zuo)成型(xing)(xing)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)，部分預應力(li)混(hun)凝(ning)土(tu)(tu)電(dian)(dian)(dian)(dian)(dian)桿(gan)(gan)(gan)(gan)供應商，電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)的(de)模(mo)具是(shi)兩(liang)個半模(mo)組成的(de)，在制(zhi)作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)時(shi)需(xu)求必定的(de)離(li)心(xin)力(li)。使水(shui)(shui)泥料構成中心(xin)空的(de)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)，然后(hou)對(dui)成型(xing)(xing)的(de)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)進(jin)行維護。水(shui)(shui)泥電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)，是(shi)重要的(de)建設資料。市政建設是(shi)重要大事，輸電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)路的(de)鋪設與運轉離(li)不開水(shui)(shui)泥電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)的(de)撐持。

因而，水泥電線(xian)(xian)(xian)桿(gan)(gan)的(de)(de)(de)質量(liang)是zui重要(yao)的(de)(de)(de)思考要(yao)素之一(yi)。水泥電線(xian)(xian)(xian)桿(gan)(gan)的(de)(de)(de)選購(gou)，建設(she)者需(xu)求多方面(mian)思考問題，8米部(bu)分預(yu)應力混凝(ning)土電桿(gan)(gan)供應商，其(qi)間質量(liang)必定是di一(yi)位的(de)(de)(de)。質量(liang)包含(han)許多方面(mian)：運(yun)用年限，分量(liang)、資料等多方面(mian)要(yao)素。我們曉得(de)(de)，水泥電線(xian)(xian)(xian)桿(gan)(gan)是使用離心力將(jiang)混凝(ning)土均勻得(de)(de)鋪設(she)在模板上終制成(cheng)的(de)(de)(de)，雖然是的(de)(de)(de)出產流(liu)程，但是技術方面(mian)，各個電線(xian)(xian)(xian)桿(gan)(gan)廠(chang)家(jia)是不一(yi)樣的(de)(de)(de)。電線(xian)(xian)(xian)桿(gan)(gan)廠(chang)家(jia)的(de)(de)(de)出產技術水平也并非是時代越久就越好，主要(yao)是看(kan)電線(xian)(xian)(xian)桿(gan)(gan)廠(chang)家(jia)的(de)(de)(de)歸納實力怎么。
