  Moreover, as shown in FIG. 4, the carrying-out process from the inside of the housing | casing 2 of the carry-out thing (pipe piece P1 and the existing pipe excision apparatus 1) after the cutting of the existing water pipe P is carried out. Since the pipe cutting device 1) is lifted from the opening 2b at the top of the housing 2 into the working cylinder 2c and then the on-off valve 2a is closed, the fluid in the existing water pipe P leaks outside the housing 2. Therefore, it is possible to carry out the work in an unrestricted water state.

  Also, as shown in FIGS. 4 and 5 (a) and 5 (b), the space between the two predetermined cut surfaces of the existing water pipe P is the predetermined excision site of the present invention, and a partition body 11 (water control body) to be described later. ), And the inner surface of the housing 2 that contacts the side peripheral surface of the upper lid 13 of the partition 11 and the side peripheral surface of the partition wall 12 is convex over the inner side surface and the inner bottom surface. A step portion 15 and a step portion 16 are formed.
