PIPING REMOVAL METHOD
To provide a piping removal method that can cut and remove piping while suppressing dispersion of powder dust or the like within the piping.SOLUTION: A piping removal method is the piping removal method which removes a removed object part that is a portion of the piping, by cutting the piping at a predetermined cutting position. The piping removal method comprises: an injection foaming step of injecting foamable resin before foaming into the inside of the piping and foaming it, so as to be solid by the foamable resin after foaming in at least the cutting position of the piping; and a cutting removal step of cutting the piping at the cutting position and then removing the removed object part, after the injection foaming step.SELECTED DRAWING: Figure 1
【課題】配管内部の粉塵等の飛散を抑制しつつ配管を切断して撤去できる配管撤去方法を提供する。【解決手段】配管撤去方法は、配管を所定の切断位置で切断することで、前記配管の一部である撤去対象部を撤去する配管撤去方法であって、前記配管の少なくとも前記切断位置が発泡後の発泡性樹脂で中実になるように、前記配管の内部に発泡前の前記発泡性樹脂を注入して発泡させる注入発泡ステップと、前記注入発泡ステップの後に、前記配管を前記切断位置で切断し、前記撤去対象部を撤去する切断撤去ステップと、を少なくとも備える。【選択図】図１
