Buried cable

The invention discloses a buried cable. The cable comprises a cable outer protective layer, and the cable outer protection layer is provided with a cable installation cavity. A cable core wire is mounted in the cable mounting cavity; two sides of the cable core wire are respectively provided with a middle spacer; the inner wall surface of the cable outer protective layer is connected through the middle spacer; the upper end and the lower end of the cable core are each provided with an elastic supporting part, the elastic supporting parts are arranged at the upper end and the lower end of the middle spacer, the elastic supporting parts are elastically deformed and limited through limiting supporting parts arranged on the inner wall of the cable installation cavity, and arched convex faces formed by the elastically-deformed elastic supporting parts make contact with the outer side face of the cable core. According to the cable, the elastic supporting parts are adopted as spring bufferingsupports at the upper en
