PURPOSE: A wave type wire pipe used in a road is provided to allow the wire pipe to be bent in a predetermined direction by integrally forming a guide plate with an inner portion of the wire pipe, such that the other end of the guide plate is spaced from the inner portion of the wire pipe. CONSTITUTION: A guide plate(3) is formed at an inner portion(2a) of a flank part(2) of a wave type wire pipe(1). One end of the guide plate(3) is integrally formed with the inner portion(2a) of the wire pipe(1). The other end of the guide plate(3) is spaced from the inner portion(2a) of the wire pipe(1), so a gap(4) is formed between the other end of the guide plate(3) and the inner portion(2a) of the wire pipe(1). The wire is inserted into a direction of the guide plate(3) attached to the inner portion(2a) of the wire pipe(1), so an end of the wire is guided by the guide plate(3) without making contact with the inner portion(2a) of the wire pipe(1). |
