施工(gong)方法
一、地埋電纜護套管(guan)管(guan)徑的選(xuan)擇
根據電(dian)纜外徑(jing)、容許電(dian)壓、電(dian)流及工程其他條(tiao)件選擇。
二、挖工程溝
根(gen)(gen)據有(you)關部門(men)規定用戶要(yao)求挖溝，其寬度、深度須根(gen)(gen)據敷設電纜根(gen)(gen)數(shu)而定。管與溝之間的(de)距離是50mm，管(guan)與管(guan)之間(jian)的距離為30mm。
三(san)、鋪設
將地埋電纜護(hu)套(tao)管(guan)放入(ru)溝(gou)中后，彎度(du)大的(de)地方為防止其纏繞(rao)或擠壓(ya)，須(xu)用(yong)水(shui)泥灌封。在兩根護(hu)套(tao)管(guan)連接口處，須(xu)用(yong)磚(zhuan)砌并用(yong)水(shui)泥將護(hu)套(tao)管(guan)管(guan)頭固定。
四、對(dui)連
兩根地埋電(dian)纜護套管(guan)(guan)對接(jie)時，先將(jiang)接(jie)頭旋(xuan)至(zhi)被接(jie)管(guan)(guan)的(de)(de)一端(duan)，然后倒旋(xuan)至(zhi)另一被接(jie)管(guan)(guan)的(de)(de)一端(duan)，再用PVC密封膠帶(dai)纏繞即可。
五、回填(tian)
按要求將(jiang)地(di)埋(mai)電纜(lan)護套鋪設(she)好后，用挖地(di)溝的原土回填即(ji)可(ke)，并將(jiang)回填土夯實。
六(liu)、注意
鋪設(she)過程中(zhong)，須放(fang)置砂土進入地(di)埋電纜護套管中(zhong)。
