Abstract
PURPOSE:To pull out an imbedded pipe by opening a long hole circumferentially at one part of a pipe body, and inserting into the long hole unfolded fan shaped wedge plates at the tips of pulling rods, and inserting into the long hole tapered wedges at the tip of a compression rod, and breaking the long hole as well as generating a crack circumferentially through compression and pulling. CONSTITUTION:Pulling rods 4 are made to be engaged with the expanded diametered recess portions of a support main body 1 and made to be rotatable. Unfolded fan shaped wedge plates 7 are provided monolithically at the tips of rods 4. A compression rod 5 is fixed at a hydraulic jack 8 whose base end portion is fixed at the support main body 1, and is expanded/contracted upward and downward, and tapered wedges 9 are provided at the tip of it. A long hole 10 is opened along the direction of circumference at one part of the upper surface of a pipe body, and then, the support main body 1 is descended, and wedge plates 7 are inserted into the long hole and rotated by 90 deg., and caught by the pipe body. And the tapered portions of wedge plates 9 are inserted into the long hole, and the pipe body is broken at its perimeter portion by means of the jack 8 as a result of the relative movements of rods 4, 5, and at the same time, a crack is generated circumferentially from the end portion of the long hole 10 and breaking-off is done.
