監(jian)(jian)控(kong)攝(she)像(xiang)(xiang)頭所用(yong)的(de)(de)(de)電(dian)(dian)線(xian)(xian)桿(gan)與普通(tong)的(de)(de)(de)電(dian)(dian)線(xian)(xian)桿(gan)有一定的(de)(de)(de)區別，監(jian)(jian)控(kong)攝(she)像(xiang)(xiang)頭選用(yong)的(de)(de)(de)水泥電(dian)(dian)線(xian)(xian)桿(gan)，要求制作(zuo)工(gong)藝(yi)上比較麻煩，在電(dian)(dian)線(xian)(xian)桿(gan)的(de)(de)(de)頂(ding)部(bu)(bu)和(he)底(di)部(bu)(bu)預(yu)留(liu)穿線(xian)(xian)孔和(he)避雷(lei)孔。監(jian)(jian)控(kong)一般采用(yong)15米(mi)電(dian)(dian)線(xian)(xian)桿(gan)和(he)18米(mi)電(dian)(dian)線(xian)(xian)桿(gan)，21米(mi)水泥電(dian)(dian)線(xian)(xian)桿(gan)幾種(zhong)。在生產監(jian)(jian)控(kong)電(dian)(dian)線(xian)(xian)桿(gan)時(shi)，預(yu)留(liu)在電(dian)(dian)線(xian)(xian)桿(gan)上的(de)(de)(de)預(yu)留(liu)孔采用(yong)鋼管預(yu)留(liu)，將5公(gong)分的(de)(de)(de)鋼管焊接在鋼筋籠(long)上，避雷(lei)孔預(yu)留(liu)18mm螺絲孔。

1，監(jian)控電(dian)線(xian)桿網線(xian)預(yu)留孔(kong)(kong)，網線(xian)預(yu)留孔(kong)(kong)預(yu)留在電(dian)線(xian)桿上(shang)下(xia)兩頭(tou)。上(shang)頭(tou)與(yu)下(xia)頭(tou)預(yu)留的位置在上(shang)頭(tou)向下(xia)20公分處，下(xia)頭(tou)向上(shang)2.5米處，用鋼管焊(han)接到(dao)鋼筋(jin)籠上(shang)即可。

水泥電線桿的焊接要求：  

1、首(shou)先兩(liang)節(jie)桿對接(jie)調(diao)直，將水泥電線桿下(xia)節(jie)放置平(ping)整的地面，然后對接(jie)上節(jie)對直。  

2、其次焊(han)(han)接(jie)(jie)固(gu)定(ding)，在(zai)水泥電線(xian)(xian)桿調直(zhi)(zhi)以(yi)后按照焊(han)(han)接(jie)(jie)位置平均打點固(gu)定(ding)，在(zai)整(zheng)個焊(han)(han)接(jie)(jie)法蘭(lan)焊(han)(han)接(jie)(jie)三個點進(jin)行固(gu)定(ding)，打點固(gu)定(ding)完(wan)成(cheng)開(kai)始校直(zhi)(zhi)，用水平儀檢(jian)測(ce)電線(xian)(xian)桿是否對直(zhi)(zhi)，在(zai)焊(han)(han)接(jie)(jie)時(shi)主要的注意的問題就是焊(han)(han)接(jie)(jie)工序以(yi)及要點。  

3、焊(han)(han)接水泥電線桿(gan)，在焊(han)(han)接時注意焊(han)(han)點(dian)均勻，整個焊(han)(han)接需(xu)要(yao)三遍焊(han)(han)接方可(ke)完(wan)成，涂(tu)刷除(chu)銹漆，除(chu)去焊(han)(han)接位置銹斑，涂(tu)刷防腐漆，電線桿(gan)注意用于高壓電力架設，如果焊(han)(han)接不(bu)牢固導(dao)致(zhi)電線桿(gan)拉力減(jian)弱強度減(jian)小從而造成損壞。

  4、偷工減料后(hou)果及影響： 

在(zai)生產水(shui)泥(ni)電(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)是(shi)減(jian)少(shao)材(cai)料(liao)(liao)使(shi)用(yong)量(liang)，水(shui)泥(ni)、鋼筋、內外環，一根電(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)可以(yi)減(jian)少(shao)20元成本(ben)，偷(tou)工(gong)減(jian)料(liao)(liao)導致(zhi)后果，不達標電(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)在(zai)安裝使(shi)用(yong)上(shang)危險極大(da)，在(zai)架線(xian)(xian)(xian)(xian)、緊(jin)線(xian)(xian)(xian)(xian)是(shi)容易拉(la)斷(duan)電(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)。偷(tou)工(gong)減(jian)料(liao)(liao)的(de)電(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)在(zai)運(yun)輸上(shang)容易壓裂，壓碎(sui)，偷(tou)工(gong)減(jian)料(liao)(liao)的(de)電(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)強度差距很大(da)，導致(zhi)運(yun)輸壓碎(sui)、緊(jin)線(xian)(xian)(xian)(xian)拉(la)斷(duan)事情不在(zai)期數。偷(tou)工(gong)減(jian)料(liao)(liao)的(de)電(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)使(shi)用(yong)年(nian)限(xian)(xian)較(jiao)短，減(jian)少(shao)水(shui)泥(ni)使(shi)用(yong)量(liang)導致(zhi)水(shui)泥(ni)電(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)強度大(da)大(da)降低，表面脫皮(pi)，使(shi)用(yong)年(nian)限(xian)(xian)減(jian)少(shao)，熱脹(zhang)冷(leng)縮；所以(yi)夏天架設電(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)時，要留(liu)出足夠的(de)余(yu)量(liang)，以(yi)免冬天時電(dian)(dian)線(xian)(xian)(xian)(xian)收縮而拉(la)斷(duan)電(dian)(dian)線(xian)(xian)(xian)(xian)或者拉(la)倒電(dian)(dian)線(xian)(xian)(xian)(xian)桿(gan)。  

架設(she)水(shui)泥(ni)電(dian)(dian)線(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)無法(fa)(fa)安裝(zhuang)拉(la)(la)線(xian)(xian)(xian)采用(yong)(yong)什么(me)方(fang)法(fa)(fa)，采用(yong)(yong)無拉(la)(la)線(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)進(jin)行施工，大彎(wan)矩水(shui)泥(ni)電(dian)(dian)線(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)主要使用(yong)(yong)在終端(duan)桿(gan)(gan)(gan)(gan)，轉(zhuan)角桿(gan)(gan)(gan)(gan)，無拉(la)(la)線(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)使用(yong)(yong)。在農(nong)村電(dian)(dian)力線(xian)(xian)(xian)路架設(she)時經常出現沒(mei)有(you)(you)地方(fang)安裝(zhuang)拉(la)(la)線(xian)(xian)(xian)，在農(nong)村狹窄地方(fang)架設(she)安裝(zhuang)水(shui)泥(ni)電(dian)(dian)線(xian)(xian)(xian)桿(gan)(gan)(gan)(gan)沒(mei)有(you)(you)辦法(fa)(fa)安裝(zhuang)拉(la)(la)線(xian)(xian)(xian)，采用(yong)(yong)什么(me)方(fang)法(fa)(fa)進(jin)行施工。

 一，根(gen)據(ju)我們多年的(de)經驗給大家分享一下無(wu)法打拉(la)(la)線(xian)怎么(me)施工(gong)，根(gen)據(ju)地(di)理環境在因地(di)而異的(de)情況下采(cai)用無(wu)拉(la)(la)線(xian)桿(gan)(gan)作為轉角桿(gan)(gan)或(huo)終端桿(gan)(gan)使(shi)用，節省拉(la)(la)線(xian)沒有地(di)方安裝的(de)問題(ti)。

 二(er)，采用(yong)混凝土(tu)澆(jiao)筑(zhu)的(de)方法解決無(wu)法安(an)裝拉線的(de)問題，在無(wu)法拉線的(de)位置(zhi)加(jia)深水泥電線桿的(de)坑基，回填一半采用(yong)混凝土(tu)澆(jiao)筑(zhu)一半的(de)方法進行施工(gong)。
