Wave structure 16 having a ridge and circumferentially continuous peaks 12
And a wave structure 20 having a valley 18. Wave structure 16
Since the peaks 12 are shared by the wave structure 20 and the wave structure 20, it is apparently recognized as a structure in which block-shaped protrusions (peaks 12) are formed at predetermined intervals in the axial direction and the circumferential direction. Ma
In addition, when focusing on the valley 14, the valley 1 of the wave structure 16 is obtained.
4 is flat and continuous at a constant thickness over the entire length in the circumferential direction.
First, the valleys 14 of the wave structure 20 are aligned over the entire length in the tube axis direction.
The valleys 14 extend in the pipe axis direction and
It is understood as a structure formed in a mesh shape in the circumferential direction.
Their to tube wall of the cable protection tube 10 is cut by the cut surface 22 through the circumferential direction of the one point of the cable protection tube 10 (central part of the mountain portion 12 in this embodiment), and extending axially . Na us, the cable protection tube 10, for example, be obtained by secondary processing of pipes formed by extrusion molding of a synthetic resin such as polyvinyl chloride.

4 is flat and continuous at a constant thickness over the entire length in the pipe axis direction
Therefore, by deforming the tube wall at the valley portion 14,
Thus, the split surface 22 can be easily opened. Also, wave structure
The valley of the structure 16 is flat with a constant thickness over the entire length in the circumferential direction.
Since it is continuous, the tube wall is deformed at the valley portion 14
Thereby, the cable protection tube 10 is bent in an arbitrary direction.
Can be done. The existing cable 28 can be accommodated in the cable protection tube 10 by opening the split surface 22, so that the utility pole 32 and the like can be moved without switching the cable 28.
