    • PROBLEM TO BE SOLVED: To provide a cable protecting pipe member capable of making improved the workability at insertion into an existing pipe, and to provide a cable protecting pipe channel that uses the cable protecting pipe member.
      SOLUTION: The cable protecting pipe member 10 is inserted into the existing pipe 200 with an existing cable 202 installed therein, and the mutual ends of the pipe member in an axial direction are connected with a joint member 42 and constitute a cable protecting pipe channel 100. The cable protecting pipe member includes a body (12) having mutually separable first and second pipe members 14, 16; the first pipe member 14 is formed with a first divided pipe part (32) and the second pipe member 16 is formed with a second divided pipe part (40), wherein the first divided pipe part (32) cooperates with the second divided pipe part (40), to form a first pipe channel part (20) for accommodating the existing cable 202. A first water cut-off member 28 cuts off the water between the first and second pipe members 14, 16 with the first and second pipe members 14, 16 connected together.

    • PROBLEM TO BE SOLVED: To provide a technique for pulling only a cable protection material attached to a cable in a duct out of the duct without having an effect on existing cables. SOLUTION: A method for pulling out a cable protection material includes the steps of: opening the cylinder of a cable protection material 20 along the direction of the length of a cable 4; separating the opened cable protection material from the cable; and pulling the separated cable protection material out of a duct 2. The fit between a fitting part 10d and a part to be fitted 10c is opened and a cable tension reduction jig 50 is towed in the duct along the cable. The cylinder of the cable protection material is thereby opened, With the cable protection material inserted into a cable protection material separating jig 60, the cable protection material separating jig is towed along the cable and the cable protection material is thereby separated from the cable.
