Method of lining an inner surface of a pipe.

摘要

An amount of resin necessary for lining an inner surface of a pipe (2) is calculated. A lining pig (13) is inserted in the pipe from an open end thereof, and the calculated amount of resin is supplied in the pipe from the open end subsequent to the insertion of the lining pig. A blocking pig (14) is inserted in the pipe behind the resin, and a pressurized liquid is supplied in the pipe subsequent to the insertion of the blocking pig thereby feeding the charged resin through the blocking pig until a front end of the resin reaches an inner end of the pipe. The resin is sucked together with the lining pig and the blocking pig so that the inner surface of the pipe is lined with the resin. <IMAGE>
