Abstract

PURPOSE: To greatly increase the follow-up deformation quantity of a pig to a pipe as compared to conventional pigs, by pushing the pig to an in wall surface of the pipe by fluid pressure after making the pig flixible.
CONSTITUTION: A cylindrical pig 4 with a bottom, to which a concave portion 4a opening to the rear is shaped while which circumferential surface whole body consisting of a flexible materials, which diameter can freely be changed, as containing a fringe portion 4b by the deflection, is connected by a corded matter 5 in a condition that the pig 4 is inserted into a pipe, the other end sides of a plurality of corded matters 5 are collected in one bundle, and a line d is connected. This is inserted into the pipe through an opening at the pressure fluid feeder 3 side while installing a mechanism 6 for providing the line d with resistance. Fluid pressure from the feeder 3 is fed to the concave portion 4a of the pig 4, the movement speed of the pig 4 is controlled by means of a resistance adding mechanism 6 while expanding the circumferential surface in the diameter direction and adhering it to the whole circumference of an inner surface of the pipe as containing the fringe portion 4b, and the pig 4 is shifted in a conduit 1
