Summary:PROBLEM TO BE SOLVED: To draw a buried pipe efficiently, if the full length of a buried pipe to be removed is drawn, by repeating an operation to hold the both ends of the buried pipe, draw a part of the pipe, cut the drawn part cylindrically, then hold the ends of the buried pipe after cut and draw a part of it. SOLUTION: A buried pipe drawing jig capable of holding a buried pipe and a rope body 1 jointly by making the rope body 1, which is passing through the length of the buried pipe to be removed, engaged with the both ends of the buried pipe. A pressure contact member 3 that receives a tensile reaction force of the rope body and that can pressure contact longitudinally the end portion of the buried pipe and a mounting part 4 that can mount/demount the pressure contact member 3 for the rope body 1 in the radial direction are provided. The pressure contact member that is mounted to the mounting part 4 enables the rope body to be engaged with the both end portions of the buried pipe and a plurality of mounting parts are provided at plural locations to a long side of the rope body.
