PIPING REMOVAL TOOL AND PIPING REMOVAL METHOD
PROBLEM TO BE SOLVED: To enable a piping mainly to be easily removed without chipping a slab.SOLUTION: This invention relates to a piping removal tool 4 for removing a piping 3 buried in a slab 2 while being passed through it without chipping the slab 2. This invention comprises a rotary blade 12 having the same diameter as an outer diameter of the piping 3 or an effective cutting radius more than a thickness of the piping 3 and capable of cutting the piping 3 along an axial direction 11; a rotary driving part 13 for rotatably driving this rotary blade 12; and an axial direction guiding mechanism 14 for moving the rotary blade 12 inserted into the piping 3 along the axial direction 11 of the piping 3.SELECTED DRAWING: Figure 2
【課題】主に、配管を、スラブをはつることなく容易に撤去できるようにする。【解決手段】スラブ２に貫通状態で埋設された配管３を、スラブ２をはつることなく撤去するための配管撤去工具４に関する。配管３の外径と同等の直径を有するか、または、配管３の肉厚と同等以上の有効切断半径を有して、上記配管３を軸線方向１１に沿って切断可能な回転刃１２と、この回転刃１２を回転駆動する回転駆動部１３と、上記配管３の内部へ挿入した上記回転刃１２を、上記配管３の軸線方向１１に沿って移動させる軸線方向案内機構１４と、を備える。【選択図】図２
