直埋電纜敷設有哪些要求

直埋拖鏈電纜敷設有哪類追求？（1）挖溝的溝底是軟松的土體，這樣是鵝卵石或硬塑垃圾要鋪100mm厚的軟土或砂層。電攬身邊的的沙子如具有刺激性耐腐蝕電攬鋁合金包皮，應處理和換土，埋深應不高于0.7m，小說穿越耕地應當不高于1m。在接入鋼結構建筑結構工程物、與地面鋼結構建筑結構工程物交叉式及躲過地面鋼結構建筑結構工程物處，可淺埋，但應使用保護的控制政策，電攬應埋于凍巖層體下類，當受前提禁止時，應使用嚴防電攬遭到損害的控制政策。（2）電覽電線敷設后，上述要鋪100mm厚的軟土或泥沙，再扣上混泥土土養護的板，覆蓋率橫向應超出電覽電線二邊其它各50mm，或用磚充當混泥土土養護的板。

（3）正中間直(zhi)接頭盒(he)上邊要有鑄鐵質或瀝青商混(hun)(hun)土確保盒(he)。（4）接線(xian)(xian)頭那么應墊(dian)以(yi)水(shui)泥(ni)水(shui)泥(ni)混(hun)(hun)凝土土的基礎板，段長度要伸到接線(xian)(xian)頭確保盒(he)兩端(duan)(duan)600?700mm，電(dian)(dian)(dian)覽自土溝扶植隧道(dao)(dao)口、人(ren)孔和(he)(he)建筑裝修物(wu)時(shi)，要穿在管(guan)(guan)(guan)(guan)內，并將孔口堵賽，以(yi)防(fang)止冒(mao)水(shui)。（5）電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)覽互不(bu)穿插(cha)，和(he)(he)非(fei)電(dian)(dian)(dian)力(li)管(guan)(guan)(guan)(guan)和(he)(he)排水(shui)管(guan)(guan)(guan)(guan)道(dao)(dao)穿插(cha)，爬過道(dao)(dao)路和(he)(he)墻邊時(shi)，也(ye)要穿在保證(zheng)(zheng)管(guan)(guan)(guan)(guan)上，保證(zheng)(zheng)管(guan)(guan)(guan)(guan)厚度超出(chu)范圍穿插(cha)點1m，穿插(cha)凈距(ju)應為(wei)高于(yu)(yu)250mm，保證(zheng)(zheng)管(guan)(guan)(guan)(guan)公稱直(zhi)徑應為(wei)高于(yu)(yu)電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)覽外徑的1.5倍。（6）直(zhi)埋電(dian)(dian)(dian)線(xian)(xian)通(tong)(tong)信電(dian)(dian)(dian)纜(lan)(lan)(lan)電(dian)(dian)(dian)線(xian)(xian)普遍用鎧(kai)裝電(dian)(dian)(dian)線(xian)(xian)通(tong)(tong)信電(dian)(dian)(dian)纜(lan)(lan)(lan)電(dian)(dian)(dian)線(xian)(xian)。在鎧(kai)裝電(dian)(dian)(dian)線(xian)(xian)通(tong)(tong)信電(dian)(dian)(dian)纜(lan)(lan)(lan)電(dian)(dian)(dian)線(xian)(xian)的復合外皮兩端(duan)(duan)要牢靠地(di)線(xian)(xian)系(xi)統，地(di)線(xian)(xian)系(xi)統電(dian)(dian)(dian)容不(bu)得當不(bu)小(xiao)于(yu)(yu)10Ω。（7）直(zhi)埋電(dian)(dian)(dian)攬(lan)在美段至(zhi)少50?100m處，電(dian)(dian)(dian)攬(lan)管(guan)(guan)(guan)(guan)接頭處、轉彎處、開始建造物(wu)等(deng)處，應軟件設(she)置看不(bu)出(chu)的東南方(fang)向標示或標樁。（8）電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)(lan)(lan)與某個(ge)輸(shu)送(song)pvc管(guan)(guan)(guan)(guan)道(dao)(dao)、路線(xian)(xian)、建筑立面(mian)物(wu)等(deng)相互之間平(ping)形和(he)(he)交差時(shi)的小(xiao)凈距(ju)，應遵(zun)循規則指定。不(bu)得將電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)(lan)(lan)平(ping)形敷設(she)于(yu)(yu)輸(shu)送(song)pvc管(guan)(guan)(guan)(guan)道(dao)(dao)的頂端(duan)(duan)或下面(mian)。
