<p><P>PROBLEM TO BE SOLVED: To provide an intra-pipe cleaning method and a reconstruction method of a pipe using it which can significantly improve the whole workability by taking such measures as devising the shape of a diffusion member used for an abrasive in the pipe. <P>SOLUTION: A suction device 24 connected to one end of the pipe 10 is operated, and the abrasive B is charged from the upstream side of the pipe 10. A traction wire 27 connected to the diffusion member 30 in the pipe 10 is towed to the upstream side, and a conical hood 32 is attached to the spherical body 31 of the diffusion member 30. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
