PROBLEM TO BE SOLVED: To provide a chip recovering device in a continuously-supplied water cutting off device which surely takes out the excess chip to the external when cutting off a fluid conduit without mixing the chip in the fluid conduit. SOLUTION: In this chip recovering device in a continuously-supplied water cutting off device for cutting off the fluid conduit 1 in a sealed state, the chip recovering device is composed of a mesh part 7 composed of a bendable elastic strip piece 10 forming an outer periphery and a soft mesh 11 attached to the periphery of the strip piece, and an operating part 6 for moving the mesh part 7 between a sealing chamber outside of an opening and the inside of the fluid conduit 1 in the opening through the opening formed on a peripheral wall of the fluid conduit, and the elastic strip piece 10 is closely abutted on an inner wall of the fluid conduit 1 by an expanding and contracting member 24 when the mesh part 7 is inserted into the fluid pipe.
