An insulating tube for an underground wire is provided to block the inflow of the underground water by filling a sealant between bodies. An underground wire is installed inside a pipe(10). A pressing unit(20) is protruded to the longitudinal direction in the front side of the pipe. A tip part of the pressing unit has a needle-shaped section. A first flange(30) is protrusively formed in an outer circumference of the tip art of the pipe. A sealant receiving unit(40) is formed in the rear tip part of the pipe. The sealant receiving unit includes an inserting groove, a receiving groove, an outflow hole, a filling hole, and a cover. The pressing unit is inserted into the inserting groove. The sealant is received in the receiving groove. One end of the outflow hole is connected to the receiving groove. The sealant is filled in the filling hole. The cover opens and closes the filling hole. A second flange(50) is protruded in an outer surface of the sealant receiving unit. |
