1.在被改換電桿的(de)桿項(xiang)打四方姑且拉線(xian)，并在上段(duan)桿焊口柱(zhu)上500m處打好互成120。部(bu)署的(de)3條拉線(xian)。

2.操作原桿起立一副人字抱桿及2—2滑車組，抱桿坐位于被改換電桿外側的(de)地面。在人字抱桿的(de)起吊相反(fan)側打(da)好抱桿姑且撿線，操作人字抱桿的(de)2—4滑車組吊緊被換桿段(duan)以上(shang)的(de)桿身(綁扎點在焊口以上(shang)一700m凹處(chu))。

3.拆開與被換桿段相連的叉梁討論并作好姑且牢靠。挖開桿根，拆除卡盤，水泥頂管，并挖至底盤處，將被改換的整根電桿向L吊(diao)離底(di)盤(pan)10nm

根據監(jian)(jian)控安(an)裝(zhuang)需求在水泥電(dian)線(xian)(xian)桿預留穿線(xian)(xian)孔(kong)，根據電(dian)線(xian)(xian)的粗(cu)細在生產水泥電(dian)線(xian)(xian)桿時(shi)預留2mm和(he)4mm的穿線(xian)(xian)孔(kong)，監(jian)(jian)控探頭連接線(xian)(xian)通過電(dian)線(xian)(xian)桿內心(xin)穿到底線(xian)(xian)線(xian)(xian)路(lu)，防(fang)止切斷線(xian)(xian)路(lu)的作(zuo)用。節省(sheng)人力(li)和(he)物力(li)，大大節約時(shi)間和(he)工期。

一，監控(kong)水泥電線桿穿線孔預留，在(zai)生產水泥電線桿時才有(you)鍍鋅(xin)鋼(gang)管連接在(zai)鋼(gang)筋骨架上，將(jiang)鋼(gang)管的外端才有(you)白紙(zhi)封堵。

二，監控(kong)水(shui)泥電線桿打(da)孔，在生產(chan)好(hao)的水(shui)泥電線桿上采用水(shui)鉆(zhan)開孔法，進行打(da)孔。
