BELT-LIKE BODY INCLUDING REINFORCEMENT MATERIAL FOR PIPE PRODUCTION OF CORRECTED PIPE AND PIPE PRODUCTION METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a belt-like body including a reinforcement material for pipe production of a corrected pipe which allows use of a reinforcement material high in yield strength and construction with large earth covering or use of large diameters and a pipe production method using it.;SOLUTION: A belt-like body 100 including a reinforcement material for pipe production of a corrected pipe is for producing a corrected pipe by winding spirally and includes a belt-like substrate 101, a rib 102 erected from the substrate 101 and a metal-made reinforcement strip 104 which is embedded so that no clearance is formed throughout the whole length of the rib 102. In the boundary between the substrate 101 and the rib 102, an inclined surface 105 which is inclined in the direction of protrusion from the outer surface of the rib 102 is formed. The end part of the reinforcement strip 104 on the side of the substrate 101 extends to the inside of the substrate 101.;COPYRIGHT: (C)2016,JPO&INPIT
