The insertion member mounting structure of the corrugated pipe and the corrugated pipe and the inlet member

摘要

There is provided a wave tube mounting structure for easily attaching a pulling member to a mounting end of the wave tube in an operation of pulling the wave tube into an existing pipe, and the wave tube and the pulling member.;(20) is attached to an end portion of the corrugated pipe when the corrugated pipe having a corrugated axial cross section is pulled in its axial direction, wherein an end of the corrugated pipe has an insertion member (20) inserted into the mounting end, The insertion member 20 has a mounting structure of the mounting end of the corrugated tube, and a corrugated tube and a corrugating member suitable for the mounting structure of the corrugated tube, and the corrugated tube is preferably provided with the engaging means 11 (11a) extending in a direction opposite to the end at the end of the corrugated tube on the inner wall of the corrugated tube and a maintenance part (11b) of the transverse groove continuously extending in the circumferential direction of the corrugated tube in the corrugated tube, And a latching portion extending from the stopper portion toward the opening of the mounting end portion, the latching groove being composed of three grooves. The wave tube has an engagement groove (11) at a predetermined interval in the longitudinal direction of the wave tube. When attaching the pulling-in member to the corrugated pipe, the corrugated pipe is cut so that the engaging means appears at the end.
