施工(gong)方法
一(yi)、地埋電纜護套管(guan)管(guan)徑的選擇(ze)
根據電纜外徑、容許電壓、電流及工(gong)程其(qi)他條件選擇。
二、挖工程溝
根據有關部門規定(ding)用戶要求挖溝，其寬度、深度須根據敷設(she)電纜根數而定(ding)。管與溝之(zhi)間的距離(li)是50mm，管與管之間的距(ju)離(li)為30mm。
三、鋪設(she)
將地埋(mai)電(dian)纜護套管(guan)(guan)放入溝中后(hou)，彎度(du)大(da)的地方為防止其(qi)纏繞(rao)或擠壓(ya)，須用水泥灌封。在兩根護套管(guan)(guan)連接口處，須用磚砌并(bing)用水泥將護套管(guan)(guan)管(guan)(guan)頭固(gu)定。
四(si)、對連(lian)
兩根地埋電纜護套管對接(jie)時，先將(jiang)接(jie)頭(tou)旋(xuan)至(zhi)被(bei)接(jie)管的(de)一(yi)端(duan)，然(ran)后倒旋(xuan)至(zhi)另一(yi)被(bei)接(jie)管的(de)一(yi)端(duan)，再用PVC密封膠(jiao)帶(dai)纏繞即(ji)可。
五、回填(tian)
按要求將(jiang)地(di)(di)埋電纜護套鋪設好后，用(yong)挖地(di)(di)溝的原(yuan)土回填即可，并將(jiang)回填土夯實(shi)。
六、注(zhu)意
鋪設過程(cheng)中，須放置砂(sha)土進入地埋電纜護套管中。
