WELDING SEWER PIPE REINFORCED BY REINFORCING TUBE AND TUBE FOR REINFORCING WELDING SEWER PIPE

摘要

The present invention relates to a welded sewer pipe reinforced by a reinforcing tube, and a tube for reinforcing the welded sewer pipe. According to the present invention, in the welded sewer pipe, an external surface of a sewer pipe (10) is reinforced by a welding connection band (100), and an internal surface of the sewer pipe (10) is reinforced by a reinforcing tube (1). The welding connection band (100) comprises an elastic band (110), a support sheet (120), and a welding sheet (130). Therefore, a repair state of the sewer pipe can be maintained for a long period of time with impregnated tube construction of a double reinforcing structure.
