直埋電纜敷設有哪些要求

直埋線纜敷設有有哪些工作請求？（1）挖開的溝底是松散的土壤，假設是石頭或硬性拉圾要鋪100mm厚的軟土或砂層。電線通信電線旁有的小石子如具有生銹電線通信電線合金包皮，應去掉和換土，埋深應不值為0.7m，穿梭到農業用地時先不值為1m。在注入工程裝修工程施工物、與下水道工程裝修工程施工物交差及跳過下水道工程裝修工程施工物處，可淺埋，但應遵循庇護錯施，電線通信電線應埋于凍土壤層壤之下，當受經濟條件的限制時，應遵循解決電線通信電線遭受破損的錯施。（2）高壓通信電纜敷設后，上述要鋪100mm厚的軟土或泥沙，再蓋緊瀝青現澆水泥混凝土土土保護措施區板，包含大小應大于高壓通信電纜下方本身各50mm，或用磚取代了瀝青現澆水泥混凝土土土保護措施區板。
