A protection tube for a subterranean cable is provided to absorb external impact by forming a lower inner circumference of the subterranean cable with a semicircular rubber tube. A protection tube for a subterranean cable includes a semicircular cover tube(10), a semicircular support tube(20), an elastic cable protection tube(30), and left and right end supports(40a). The semicircular cover tube wraps and protects an upper part, a left part, and a right part of the subterranean cable. The semicircular support tube is closely adhered to a lower part of the semicircular cover tube and forms a circle. The elastic cable protection tube wraps and protects the subterranean cable while extending and fixing the semicircular support tube in a longitudinal direction. The left and right end supports wrap and protect right and left lower parts of the semicircular support tube. |
