直埋電纜敷設有哪些要求

直埋電線電纜敷設幾大問題耍求？（1）挖土的溝底是比較松軟的巖石層，要是鵝卵石或硬塑垃圾要鋪100mm厚的軟土或砂層。電覽邊上的土壤如帶有浸蝕電覽廢金屬包皮，應快速清理和換土，埋深應不高于0.7m，穿線農業用地需要不高于1m。在帶來房屋建筑裝修施工物、與下水道房屋建筑裝修施工物交叉性及躲過下水道房屋建筑裝修施工物處，可淺埋，但應采用庇護安全方案，電覽應埋于凍巖石層以上，當受標準制約時，應采用解決電覽遭受到受傷的安全方案。（2）高壓電覽敷設后，表面要鋪100mm厚的軟土或泥沙，再蓋緊瀝青混疑土構件土確保板，重疊大小應已經超過高壓電覽更替在內各50mm，或用磚帶替瀝青混疑土構件土確保板。

（3）中部連(lian)接(jie)(jie)頭盒(he)外(wai)(wai)(wai)賣要有不銹鋼(gang)或瀝青(qing)現澆混凝(ning)土(tu)土(tu)保(bao)護(hu)(hu)性盒(he)。（4）連(lian)接(jie)(jie)管(guan)(guan)(guan)下列(lie)應(ying)(ying)墊以瀝青(qing)混泥(ni)土(tu)土(tu)地(di)基(ji)板，長寬高(gao)要伸長連(lian)接(jie)(jie)管(guan)(guan)(guan)庇護(hu)(hu)盒(he)兩(liang)端600?700mm，低壓電(dian)(dian)(dian)(dian)(dian)纜(lan)自土(tu)溝扶植隧(sui)道(dao)工程(cheng)、人孔和建筑裝(zhuang)修物時，要穿在管(guan)(guan)(guan)上，并(bing)將(jiang)出口網絡堵塞，網絡響應(ying)(ying)過慢(man)或許卡(ka)死，控制滲漏水。（5）數(shu)據(ju)線(xian)(xian)(xian)(xian)同學之間(jian)交(jiao)差，和非熱電(dian)(dian)(dian)(dian)(dian)廠管(guan)(guan)(guan)和給(gei)水管(guan)(guan)(guan)交(jiao)差，小說(shuo)穿越道(dao)路和墻面墻壁時，也要穿在自我(wo)自我(wo)保(bao)護(hu)(hu)措施(shi)管(guan)(guan)(guan)內，自我(wo)自我(wo)保(bao)護(hu)(hu)措施(shi)管(guan)(guan)(guan)厚(hou)度稍微超(chao)出交(jiao)差點1m，交(jiao)差凈距不得(de)高(gao)于250mm，自我(wo)自我(wo)保(bao)護(hu)(hu)措施(shi)管(guan)(guan)(guan)內徑(jing)不得(de)高(gao)于數(shu)據(ju)線(xian)(xian)(xian)(xian)外(wai)(wai)(wai)徑(jing)的(de)(de)1.5倍。（6）直(zhi)埋(mai)電(dian)(dian)(dian)(dian)(dian)覽(lan)一般的(de)(de)采用鎧裝(zhuang)電(dian)(dian)(dian)(dian)(dian)覽(lan)。在鎧裝(zhuang)電(dian)(dian)(dian)(dian)(dian)覽(lan)的(de)(de)復合外(wai)(wai)(wai)皮兩(liang)端要牢靠等(deng)電(dian)(dian)(dian)(dian)(dian)位連(lian)接(jie)(jie)，等(deng)電(dian)(dian)(dian)(dian)(dian)位連(lian)接(jie)(jie)功率電(dian)(dian)(dian)(dian)(dian)阻不許大過10Ω。（7）直(zhi)埋(mai)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)纜(lan)在漸漸段每過50?100m處，電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)纜(lan)線(xian)(xian)(xian)(xian)接(jie)(jie)頭處、轉彎處、進入到古建筑群等(deng)處，應(ying)(ying)裝(zhuang)置分明的(de)(de)東南方向(xiang)標(biao)示或標(biao)樁。（8）纜(lan)線(xian)(xian)(xian)(xian)與許多(duo)線(xian)(xian)(xian)(xian)路、路線(xian)(xian)(xian)(xian)、建筑工程(cheng)施(shi)工物等(deng)之中平(ping)形和交(jiao)錯式時的(de)(de)小凈距，應(ying)(ying)按照實(shi)驗室管(guan)(guan)(guan)理標(biao)準(zhun)(zhun)標(biao)準(zhun)(zhun)。禁令(ling)將(jiang)纜(lan)線(xian)(xian)(xian)(xian)平(ping)形敷設于線(xian)(xian)(xian)(xian)路的(de)(de)頂部或留言板。
